Web Conferencing: A Boon to Businesss

It is Sunday evening and you are preparing again to go on a business trip. Monday morning the alarm goes off at 4:00 am, you drag your body and your briefcase to your car, drive to the airport, wait in a long line, get on a plane, get off a plane, and find your way to your client's office. When you finally get home Monday night, you have spent more time traveling than meeting and you have dozens of emails and several important phone calls to return.

According to leading web conferencing service providers, the typical sales cycle can be cut two to three weeks with web conferencing. Providing a virtual conference room environment, web conferencing eliminates the need to travel, linking geographically disperse workgroups and telecommuters. The return on investment for web conferencing can be measured not only in dollars and cents, but also in personnel efficiency, knowledge distribution and increased sales opportunities.

The ability to virtually link workgroups and project teams enables real-time collaboration, a task that once required lengthy email threads or face-to-face meetings.

Web conferencing enables businesses to:

• Reduce operating costs
• Minimize unnecessary travel
• Close sales and negotiate contracts faster
• Enhance the efficiency and effectiveness of communication
• Deliver clear, concise and consistent training
• Encourage real-time collaboration between distant and local co-workers
• Engage in greater levels of communication with clients and business partners

Since its inception, web conferencing usage has expanded to a number of business applications such as daily sales and marketing efforts, interaction with co-workers and customers, corporate presentations and training initiatives. Financial corporations use web conferencing for internal meetings, customer briefings, employee training, client consultations and investment workshops. Healthcare and pharmaceutical companies use Web conferencing for product promotion and marketing, sales presentations and demonstrations, and product training and development. Educational institutions use web conferencing for project teams and student workshops. And, government agencies rely on web conferencing for training and inter-agency communication.

Most organizations use outsourced web conferencing. Why? Because of the quickly changing technology, businesses opt not to invest in what could soon be obsolete. In addition, on a day-to-day basis, it is more cost effective to have web conferencing outsourced. Additional reasons include:

• Leading edge functionality provides greater levels of security, moderator control, and participant options.
• Your people can now focus on your core business, not support systems.
• The external company makes the investment in new features so that your fixed costs are reduced and your overall expenditures are lowered.
• With no capital expense, new technology can be implemented with minimal impact to the bottom line.

When beginning the search for a web conferencing solution, start with setting your objectives and determining the features you require. Here are a few basic questions that should be answered:

• How many participants do you anticipate attending your online meetings or events?
• Will the number of participants remain consistent from meeting to meeting or will the number change?
• How many meetings will be conducted each week, month, quarter? Will usage fluctuate depending on the time of the year?
• What type of content will be presented (Power Point slides, software applications, web-based applications, documents, or spreadsheets)?
• What degree of interactivity do you require (Q&A, polling/voting, application sharing, text chatting, live video, file sharing, etc.)?
• Do you want your own software or a hosted solution?
• How much technical support or event management support do you require?
• What is your monthly budget?
• Are there any special security requirements?

Once you have determined your requirements, screen a number of vendors. Visit their web site, review live demos, and seek client testimonials. Here are few suggestions for choosing a vendor:

Select a pricing model. Determine whether you want to pay-per-use (you pay only for the time you and your attendees spend in web conferences) or pay-per-seat (you pay a flat monthly fee for a certain number of "seats"). Pay-per-use pricing is the better conservative choice for most companies learning to how to use web conferencing for their business. You avoid set up charges and you don't have to monitor the number of concurrent users in order to avoid overage charges. You can always start with a pay-per-use plan and switch to a pay-per-seat plan once there is a clear, long-term financial advantage.

Get the features you need. Some web conferencing solutions only support online presentations while others offer full-featured packages that include polling, chatting, application-sharing, white boarding and group web surfing. Make sure that the product meets your needs.

Check into customer support levels. Is training and ongoing support available? What hours? Is there an extra fee? Is there a telephone number available so that you can contact a support person or is only email support offered? What are their support hours? Call each vendor's customer service number and see if you get a live person vs. a menu or voice mail. You don't want to be in a situation where an attendee has technical problems joining a critical meeting and not be able to contact a live person immediately.

Consider security requirements. Depending on the audience and the information being sharing, security may be a concern. Most solutions are secure enough and do not store meeting data any place except on the presenter's PC. Participants only see a graphical representation of the data through a standard web browser. Some services provide pass code authorization, basic encryption, and the ability to lock and unlock the meeting.

So, the next time Sunday night comes around and you are faced with another week of travel, email trails, difficulty in scheduling training and long lead times in closing sales and negotiating contracts, do yourself a favor and look into web conferencing for your business.

Tips On Planning A Successful Video Conference

Planning a successful video conference can actually be harder then it sounds. There are several key factors you want to make sure and get right or your conference could become a total nightmare. This short article gives several tips on making sure you succeed with your next video conference.

Nobody likes long-winded meetings and video conferences are no different. Always plan your conferences to last no longer then 1 or 2 hours long. Longer sessions will leave participants tired and bored.

Make sure you prepare an agenda before the event. Double check to make sure you have all of your graphic aids, teaching materials and any other important or relevant materials on hand. Prepare a suitable seating arrangement and ensure that nameplates or tags (if you use them) are clearly legible and nothing is misspelled.

Try to plan your video conference as far in advance as possible. Make sure you do the necessary coordination with your company's IT department for any support you may need in order for your conference to be a success. If your dealing with an overseas location early preparation and coordination is vital to your success.

Attend all test sessions to make sure that your video link is clearly working properly. Use this time to also familiarize yourself with the equipment that will be used during the session. Hand any and all materials for transmission to the video conferencing site technician at least two days in advance so that he/she can get familiar with it. For optimum readability, use large and clear fonts. Use a wide margin, as the sides will be slightly cut off on screen. Keep to the landscape format, with simple pictures and few words.

Prepare a list of questions and answers prior to the conference in order to keep the session flowing in a smooth, quick manner. Arrange for participants to assemble at the video conferencing venue 10 minutes before the session begins so that you will have time to hand out all materials.

Some final tips include:

· Dress appropriately

· Arrive 15 minutes early to spot any last minute glitches

· Avoid wearing intense colored cloths to include all-light or all-dark clothing

· Avoid distracting gestures during the conference to include finger tapping and facial expression

· Test the microphones to be used during the conference in order to find any that may have flaws.

A successful video conference can be done all it requires is an attention to detail prior to and leading up to the minute the conference actually starts. Spend the necessary time needed to do the things this article outlines and you'll have everyone talking about how professional you are when it comes to setting up a video conference.

Video Killed The Telephone Star ...

You know the 80's song, "Video Killed the Radio Star." It was a big hit and one of the first videos to air on MTV. Well, what came true for music video is on it's way to becoming true for telephone.

You're the star of all your phone conversations already, right? Everyone loves to hear your voice and hold endless conversations on the phone with you ? well, you better get prepared to dress up for your appearances now too.

Yup, video phones are now the newest trend to hit the market and it's not being provided via your traditional phone carrier either. The video phone is available only through a broadband phone provider or phone supplier, but it is already taking off in the market as the next household necessity much like the cell phone and high speed Internet did.

My Privacy ? I Just Got Out of the Shower!

Before you worry about invasion of privacy issues, like just getting out of the shower, most video phones are optional in their viewing modes. This means you have the option of being on camera or not. Phew, got that off of your chest.

The Entire Globe

Now the great part is that it is through the broadband voice providers that most broadband phone services are available globally. So it is very likely that if you have relatives afar, you can video phone with them overseas.

Cost Savings with a Catch

With broadband phone calling, long distance or international is now running as low as 3 cents a minute or less so you don't pay much to call at all. You might even call it a steal. What's the catch? Well, it's the video phones themselves. The phones run about $500.00 or more a piece. Yikes!

With a little shopping ingenuity however you can find lower prices on these video phones. Packet8, a VoIP broadband phone company has a mail-in rebate for the time being on their line of video phones to notch down their price 50%. Their phones after rebate run at $250.00, which for many households, may still be a little too steep.

History Promises the Trend

Don't get too discouraged by phone prices though, this trend is still in a growing stage. Cell phones are free these days and they use to be only afforded by the rich and famous. Everyone has a cell phone now, a camera phone for that matter. So if price holds you back now, you can anticipate lower prices and even free offers in the future.

Video Phones Save On Travel

If you travel to visit relatives often or even once a year just to see them face to face, the video phone may very well pay for itself in travel expenses alone. So you can't give them a hug, well would you believe there is a prototype for a virtual kissing phone coming out for cell phones? Yes, you can virtually smooch back and forth between another phone owner.

Technology will never cease to amaze, and prices can't stay up forever so eventually you will more than likely find yourself a consumer in the video phone market. Rest assured today's growing technologies will have you saying, "Back in my day." I already say it.

How Video Conferencing Works - Multimedia, Interactive Communication Across the Miles

You may think you understand video conferencing pretty well until someone who isn't at all familiar with it approaches you for a simple definition. When they ask, "What exactly is video conferencing?" you could suddenly realize you're at a loss for words.

The simplest definition of how video conferencing works is simply by the integration of video, audio and peripherals to enable two or more people to communicate simultaneously over some type of telecommunications lines. In other words, you are transmitting synchronized images and verbal communications between two or more locations in lieu of them being in the same room. How video conferencing works is a little bit harder to explain than answering the question, "What is video conferencing?"

Millions of people use video conferencing every day around the globe, but very few people know just how the technical aspects of the process work. The main ingredients of successful video conferencing are video cameras, microphones, appropriate computer software and computer equipment and peripherals that will integrate with the transmission lines to relay the information.

The analog information recorded by the microphones and cameras is broken down into discreet units, translating it to ones and zeros. A Codec encodes the information to a digital signal that can then be transmitted to a codec at the other end, which will retranslate these digital signals back into analog video images and audio sounds.

The theory's the same, the transmission has changed

In the earlier days of video conferencing, T1, ATM and ISDN lines were used almost exclusively but were really only practical for room-based video conferencing systems. These dedicated lines were expensive and only large corporations tended to have the facilities and money to invest in this type of set-up.

As the Internet became more a part of the everyday lives of all businesses, however, it changed how video conferencing was conducted. The TCP/IP connections of the Internet are much less expensive and can carry large quantities of information, including video packets for conferencing, relatively easily. Because of this, video conferencing has become much more prevalent in small businesses and in desktop packages that can be set up with software for computer-to-computer networking.

Compression makes video transmission practical

The problem that arises when you convert analog to digital for transmission is the loss of clarity in an image. Analog signals are a continuous wave of amplitudes and frequencies showing shades and ranges of color as well as depth and brightness. When you convert to digital, which is strictly 0's and 1's, you then need to develop a grid to represent values, intensities and saturations of different color values so that the image can be interpreted and reformed at the receiving end.

This vast amount of digital information requires huge bandwidth and means that the time it would take to transmit video images would be impractical for most applications. That's where compression is crucial. When determining how video conferencing works, one of the most important elements is the compression ratio.

The higher the compression ratio, the more quickly the information is capable of being transmitted. In many cases, however, this also means some loss in clarity or audio/video quality. For instance, a compression ratio of 4:1 would be terribly slow but have a fantastic picture quality. But by the time it was transmitted, everyone at the other end would probably have left the room for a cup of coffee. Lossy compression discards unneeded or irrelevant sections of a signal in order to transmit only the essentials, speeding up the transmission time significantly but sometimes resulting in loss of quality.

Compression can either be intra-frame or inter-frame for material that is repetitive or redundant, such as that wall behind the conference participant. Since the wall remains static and never changes, this image is redundant and can be eliminated from transmissions to an extent with proper compression. Intra-frame compression assumes the redundancy will be present in parts of a frame that are close to each other. Inter-frame compression assumes that there is redundancy over time (i.e., like that wall). Either of these can achieve a fairly high degree of accuracy and reduce the bandwidth needed for transmittal of signals.

A newer version of compression/decompression is SightSpeed technology, developed by Cornell University. SightSpeed compresses only images considered essential and eliminating what is considered 'filler,' relying on the brain to fill in the decompression at the other end. Based on an artificial intelligence model, SightSpeed achieves compression of about 90:1, compared to the typical 15:1 for video conferencing.

Any video conferencing session you use will provide compression of the transmission signal. The key is determining the balance between speed and video picture quality that is right for your needs.

Point to point video conferencing

Point to point video conferencing is just what it sounds like - a link between two different points on the planet, or two different video conferencing terminals. It could be between an office in New York City and a conference room in Munich. Point to point video conferencing can easily be initiated by someone on one end contacting the other end as though making a standard telephone call. There are no special arrangements to be made other than knowing that the participants will be there.

Multipoint conferencing is more complex

Multipoint conferencing is more complicated because it has to coordinate several different locations simultaneously. Since you can't be in direct contact with several places at once while they are all in contact with others, you need one source that will tie them all together. In video conferencing, this is called a multipoint bridge or multipoint conferencing unit (MCU).

An MCU enables multi-location video conferencing by providing a sort of "central processing center" for all of the locations through which all the information flows. The MCU receives all information from the various locations and then sends it out to each location. In some cases the MCU is located on a particular PC, and in other cases it is located on a remote server (the most common structure, particularly for more powerful MCU networks).

Audio is usually sent and received simultaneously in all locations with an MCU with no problem because of the relatively small bandwidth needed for transmittal. It is broadcast in what is called "full duplex" mode, meaning everyone can talk and hear at the same time with no cutting off when one person or another speaks.

Video transmission, however, can be broadcast in a number of ways with an MCU depending upon the quality of the software and the complexity of the system. Some common types of video transmission for video conferencing include:

• Continuous Presence video conferencing, which allows up to four conference sites to be seen simultaneously on split screens. This is usually used if you have a small group or individuals in separate locations and will primarily be seeing close-up shots.
• Universal Control video conferencing is controlled by the initiating conference site. The primary site determines who sees what at all other sites.
• Voice Activated video conferencing is by far the most common type used today. The image with these systems shifts to the site that is currently activating the microphone so that you can always see whoever is speaking. However, if there is a good deal of background noise participants should mute their microphones when they aren't talking in order to avoid the image jumping about needlessly.

Overcoming the language barrier

Obviously, communicating through video conferencing can't be achieved unless both ends of the conference are "speaking the same language." That is, whatever is being transmitted electronically will need to be reassembled properly and heard and seen clearly at the other end. The Codec system (Coder-Decoder) is useless if both ends aren't using the same virtual language to interpret the signals.

The International Telecommunications Union (ITU) developed a set of standards in 1996 dubbed H.323 to outline specific guidelines for Video Conferencing standards and protocols so that compliance and support across networks would be easier to achieve and maintain. Since then, many manufacturers and developers of video conferencing tools have adopted the H.323 guidelines as their own.

Web conferencing solutions such as Click to Meet, Lotus's SameTime, and WebEx also offer corporate solutions that are based on Internet video conferencing. These systems have shared protocols that can be downloaded and used anywhere at any location for subscribers through the Internet. These are becoming more popular with companies who like the convenience and user-friendliness. They will no doubt become more and more refined over time, vying with and perhaps surpassing the H.323 standards.

Overcoming firewall issues

There are, of course, obstacles to overcome when you take a look at how video conferencing works. After all, you're sending vast amounts of translated data either directly or through a gatekeeper system (the MCU) that is switching and transferring information between a variety of computers. Just about any business these days has a firewall system to provide security and protect the system from potential viruses. Trouble is, many firewalls also block the transmission of data for video conferencing.

Recent innovations have largely circumvented these problems by designing firewall solutions that recognize video conferencing signaling requests and allow the information packets to bypass the firewall or router without disabling the firewall protection for other traffic. Even with this, however, there may be occasions when packets are dropped because of heavy traffic on the system, so investing in a firewall system that can handle substantial traffic is essential to quality video conferencing performance.

How video conferencing works will certainly evolve over time and improve in the coming years, but a basic understanding of what it is and how it works now will help you make the best choice for you when you're ready to begin using video conferencing yourself.

The History of Video Conferencing - Moving Ahead at the Speed of Video

No new technology develops smoothly, and video conferencing had more than its share of bumps along the way before becoming the widely used communications staple it is today. The history of video conferencing in its earliest form goes back to the 1960's, when AT&T introduced the Picturephone at the World's Fair in New York. While viewed as a fascinating curiosity, it never became popular and was too expensive to be practical for most consumers when it was offered for $160 a month in 1970.

Commercial use of real video conferencing was first realized with Ericsson's demonstration of the first trans-Atlantic LME video telephone call. Soon other companies began refining video conferencing technologies, including such advancements as network video protocol (NVP) in 1976 and packet video protocol (PVP) in 1981. None of these were put into commercial use, however, and stayed in the laboratory or private company use.

In 1976, Nippon Telegraph and Telephone established video conferencing (VC) between Tokyo and Osaka for company use. IBM Japan followed suit in 1982 by establishing VC running at 48000bps to link up with already established internal IBM video conferencing links in the United States so that they could have weekly meetings.

The 1980's introduce commercial video conferencing

In 1982, Compression Labs introduces their VC system to the world for $250,000 with lines for $1,000 an hour. The system was huge and used enormous resources capable of tripping 15 amp circuit breakers. It was, however, the only working VC system available until PictureTel's VC hit the market in 1986 with their substantially cheaper $80,000 system with $100 per hour lines.

In the time in between these two commercially offered systems, there were other video conferencing systems developed that were never offered commercially. The history of video conferencing isn't complete without mentioning these systems that were either prototypes or systems developed specifically for in-house use by a variety of corporations or organizations, including the military. Around 1984, Datapoint was using the Datapoint MINX system on their Texas campus, and had provided the system to the military.

In the late 1980's, Mitsubishi began selling a still-picture phone that was basically a flop in the market place. They dropped the line two years after introducing it. In 1991, the first PC based video conferencing system was introduced by IBM - PicTel. It was a black and white system using what was at the time an incredibly inexpensive $30 per hour for the lines, while the system itself was $20,000. In June of the same year, DARTnet had successfully connected a transcontinental IP network of over a dozen research sites in the United States and Great Britain using T1 trunks. Today, DARTnet has evolved into the CAIRN system, which connects dozens of institutions.

CU-SeeMe revolutionizes video conferencing

One of the most famous systems in the history of video conferencing was the CU-SeeMe developed for the MacIntosh system in 1992. Although the first version didn't have audio, it was the best video system developed to that point. By 1993, the MAC program had multipoint capability, and in 1994, CU-SeeMe MAC was true video conferencing with audio. Recognizing the limitations of MAC compatibility in a Windows world, developers worked diligently to roll out the April 1994 CU-SeeME for Windows (no audio), followed closely by the audio version, CU-SeeMe v0.66b1 for Windows in August of 1995.

In 1992, AT&T rolled out their own $1,500 video phone for the home market. It was a borderline success. That same year, the world's first MBone audio/video broadcast took place and in July INRIA's video conferencing system was introduced. This is the year that saw the first real explosion in video conferencing for businesses around the globe and eventually led to the standards developed by the ITU.

International Telecommunications Union develops coding standards

The International Telecommunications Union (ITU) began developing standards for video conferencing coding in 1996, when they established Standard H.263 to reduce bandwidth for transmission for low bit rate communication. Other standards were developed, including H.323 for packet-based multi-media communications. These are a variety of other telecommunications standards were revised and updated in 1998. In 1999, Standard MPEG-4 was developed by the Moving Picture Experts Group as an ISO standard for multimedia content.

In 1993, VocalChat Novell IPX networks introduced their video conferencing system, but it was doomed from the start and didn't last. Microsoft finally came on board the video conferencing bandwagon with NetMeeting, a descendent of PictureTel's Liveshare Plus, in August of 1996 (although it didn't have video in this release). By December of the same year, Microsoft NetMeeting v2.0b2 with video had been released. That same month, VocalTec's Internet Phone v4.0 for Windows was introduced.

VRVS links global research centers

The Virtual Room Videoconferencing System (VRVS) project at Caltech-CERN kicked off in July of 1997. They developed the VRVS specifically to provide video conferencing to researchers on the Large Hadron Collider Project and scientists in the High Energy and Nuclear Physics Community in the U.S. and Europe. It has been so successful that seed money has been allotted for phase two, CalREN-2, to improve and expand on the already in-place VRVS system in order to expand it to encompass geneticists, doctors, and a host of other scientists in the video conferencing network around the world.

Cornell University's development team released CU-SeeMe v1.0 in 1998. This color video version was compatible with both Windows and MacIntosh, and huge step forward in pc video conferencing. By May of that year, the team has moved on to other projects.

In February of 1999, Session Initiation Protocol (SIP) was launched by MMUSIC. The platform showed some advantages over H.323 that user appreciated and soon made it almost as popular. 1999 was a very busy year, with NetMeeting v3.0b coming out, followed quickly by version three of the ITU standard H.323. Then came the release of iVisit v2.3b5 for both Windows and Mac, followed by Media Gateway Control Protocol (MGCP), version 1. In December, Microsoft released a service pack for NetMeeting v3.01 (4.4.3388) and an ISO standard MPEG-4 version two was released. Finally, PSInet was the first company to launch H.323 automated multipoint services. Like we said, 1999 was a very busy year.

SIP entered version 1.30 in November of 2000, the same year that standard H.323 hit version 4, and Samsung released their MPEG-4 streaming 3G video cell phone, the first of its kind. It was a hit, particularly in Japan. Rather predictably, Microsoft NetMeeting had to release another service pack for version 3.01.

In 2001, Windows XP messenger announced that it would now support Session Initiation Protocol. This was the same year the world's first transatlantic tele-surgery took place utilizing video conferencing. In this instance, video conferencing was instrumental in allowing a surgeon in the U.S. to use a robot overseas to perform gall bladder surgery on a patient. It was one of the most compelling non-business uses in the history of video conferencing, and brought the technology to the attention of the medical profession and the general public.

In October of 2001, television reporters began using a portable satellite and a videophone to broadcast live from Afghanistan during the war. It was the first use of video conferencing technology to converse live with video with someone in a war zone, again bringing video conferencing to the forefront of people's imaginations.

Founded in December of 2001, the Joint Video Team completed basic research leading to ITU-T H.264 by December of 2002. This protocol standardized video compression technology for both MPEG-4 and ITU-T over a broad range of application areas, making it more versatile than its predecessors. In March of 2003, the new technology was ready for launch to the industry.

New uses for video conferencing technologies

2003 also saw the rise in use of video conferencing for off-campus classrooms. Interactive classrooms became more popular as the quality of streaming video increased and the delay decreased. Companies such as VBrick provided various MPEG-4 systems to colleges across the country. Desktop video conferencing is also on the rise and gaining popularity.

Companies newer to the market are now refining the details of performance in addition to the nuts and bolts of transmission. In April of 2004, Applied Global Technologies developed a voice-activated camera for use in video conferencing that tracks the voice of various speakers in order to focus on whoever is speaking during a conference call. In March 2004, Linux announced the release of GnomeMeeting, an H.323 compliant, free video conferencing platform that is NetMeeting compatible.

With the constant advances in video conferencing systems, it seems obvious that the technology will continue to evolve and become an integral part of business and personal life. As new advances are made and systems become more reasonably priced, keep in mind that choices are still determined by network type, system requirements and what your particular conferencing needs are.

Seven Steps to a Vital Videoconference

When it's time for your fifteen minutes of fame will you be ready? With videoconferencing becoming common place in 21st century communication, executives, entrepreneurs, and leaders need to be media savvy. Here's how to put your best face forward:

1. Prepare. It's not enough to show up to speak. Practice with the technology an hour before your presentation and rehearse your message points. Don't wing it.

2. Pause and Listen. Expect time delays. A weak video signal could cause a delay or echo. Allow ample time for your message to reach the other site and wait for a response before you resume making new remarks.

3. Use Small Gestures. Actions are amplified on videoconference. Wild, sweeping movements can result in distorted, fuzzy images.

4. Appoint a Moderator. The moderator facilitates the meeting, introduces guests, and keeps the presentation movoing. The moderator or a designated person operates the technology to free speakers to focus on the message.

5. Dress for TV. Avoid distracting jewelry, shiny clothing, and large, bold patterns. Keep another shirt or blouse in the office for late day videoconferences. Perspiration stains and wrinkles will be noticeable on video. Keep powder handy for shiny noses and bald spots.

6. Create a Connection. Begin with hello. The wave is a standard greeting in videoconferencing. Use the zoom function on the camera to establish eye contact. It's difficult to communicate without viewing facial expressions from the remote site.

7. Minimize Distractions. Keep noise down by restricitng movement in and out of the room. Turn off all beepers and cell phones at the beginning of the meeting. Place a "Do Not Enter" sign on the door and change activities frequently to maintain attention and avoid the boredom factor.
