The Evolution Of Audio Video Conferencing

Writen by Steve Valentino

Audio video conferencing is a shorthand way of describing a virtual conference where no one has to leave her office to meet up with the rest of the group. A virtual conference may use telephones, televisions, computers, conferencing software, collaborative software, file sharing, headsets, the Internet, or any combination of these equipments and tools. Slide presentation, streaming audio, and document sharing are some of the extras you can incorporate into this conferencing method. The ultimate goal is to make the meeting as realistic as possible, where everyone can see each other, hear each other, view and modify projects, and so on – all at a cost that eventually pays for itself in travel savings.

The audio video industry has yet to work out all of the kinks. As you can imagine, there can sometimes be technical difficulties in which lines can get torn down in a storm, computers and other equipment can malfunction, and so on. Furthermore, audio video conferencing doesn't work very well for complicated communication techniques, such as those used in closing a sales deal. Audio video conferencing lends a rather impersonal air to meetings, and socializing and bonding don't take place as they would in the real world.

You can set up for audio video conferencing in a number of different ways. The older method, still great for a wide variety of teleconferencing purposes, is to have one group in one room, another group in another room (perhaps in another city or country), and have them talk to each other. Each of the two groups utilizes a television, a video camera mounted on the television, a speakerphone, and perhaps some file sharing software for collaboration on computer projects. The newer style is online audio video conferencing, wherein each participant has her very own station in her very own office. This utilizes a computer, the Internet, a web cam, a headset, and file sharing software. This new method allows for even greater ease of planning and attendance, applicability to collaboration, and mobility. You could attend a web conference on the beach while the other attendees are on a train, at home, in a restaurant, or anywhere else.

Video Conferencing Basics

Writen by Navneetkumar Kumar

This article will provide you a brief introduction about what actually video conferencing is. By video conferecing we can connect with some other identity and also can see the video online in real time. It is now useful and very interesting technology and widly used worldwide.

What is Video Conferencing: Video conferencing is the integration of video, audio and peripherals to enable two or more people to communicate simultaneously over some type of telecommunications lines. By video conferencing you are transmitting synchronized images and verbal communications between two or more locations in lieu of them being in the same room.

Video conferencing ingredients: 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.

How video conferencing works: 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.

In the earlier days, video conferencing was very much expensive than today. Some time back video conferencing was used by T1, ATM and ISDN lines. These all process were very costly for video conferencing. Since internet is very cheap and it is a very good medium for video conferencing. The TCP/IP connections of the Internet are much less expensive and can carry large quantities of information for video conferencing, 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.

The problem faced was in video conferencing was that when we convert analog to digital for transmission then it is the loss in clarity of image. The most important factor in video conferencing 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.

Advantages of video conferencing: Using video conferencing you can communicate with whole groups of people at once either through networking a group of computers or by form of broadcast. This is a huge step forward for both companies and for schools. video conferencing is very useful for students in their studies. Students can enjoy learning this way much more than from a textbook. Informed people can talk to classes and help them learn, where otherwise they wouldn't be able to because of time and distance restrictions. This is also a bonus for children who have different learning styles. The more visual types who understand better when they can see what they're working with.

Web Conferencing Software Choosing Your Application

Writen by Diane Parker

It is worth bearing in mind that, when you are deciding which web conferencing application to utilize, none of the applications currently available will do everything well.

Each system has its own strengths and weaknesses and it is therefore important for you to identify what you hope to gain from your web conferencing application. The first step you should take is to draw up a list of essential features - decide what the most important aspects of web conferencing are to you and what you hope to gain from your system.

By identifying what is most important to you, you can narrow down your field of selection to those vendors who are supplying a product that most closely matches your requirements. By immediately discarding those that do not match your criteria, you will find yourself considering a far more manageable number of applications.

Communication: Meetings, Webcasts and Webinars For example, if the key function you want your web conferencing application to perform is that of communication then you require an application that will allow you to exchange with others. An application that has the capability to host meetings, transmit webcasts and hold training seminars will be required.

Different web conferencing applications have different capabilities, some allowing you to invite hundreds of delegates to your seminar, others allowing a maximum of say, ten. Levels of interaction vary too so be very clear about what functions you will need your application to be able to perform.

Before investing in your new system you should thoroughly review exactly what each provider is offering to ensure it meets with your requirements.

Vendors:

Vendors of this type of application include:

* Centra

* Netbriefings

* Placeware

* Smiletiger

* Spartacom

Online Collaboration and Project Management

Online collaboration software is particularly effective for project management. These applications allow users to share files and documents, to view files at the same time and update documents in real time. Previously, this level of collaboration could only be achieved by being physically present in the same location but online collaboration applications are extremely effective.

Vendors:

Vendors of this type of application include:

* Genesys

* Interwise

* Viditel

* WebEx

You need to consider too, whether or not your chosen application will be compatible with your existing software and operating platform. This information will be readily available from the application vendor. Also, do you have sufficient broadband capability to run your chosen application?

The cost, of course, is a major consideration when deciding upon your web conferencing application and will undoubtedly influence your ultimate decision. Applications range from the elementary (some can even be set up with a plug-in the likes of Yahoo Messenger) to the most sophisticated systems that will allow broadcasting to hundreds of delegates.

When deciding how much to spend, take into account how much money you are already spending in terms of time and money on travel. The chances are, if you choose your application sensibly, you will earn back its cost in a relatively short period of time.

Wireless Video Conferencing How The Smithsonian Went Wireless

Writen by Harold German

Nestled modestly along the shores of the Chesapeake Bay, the Smithsonian Environmental Research Center (SERC) goes about its daily business of finding solutions to grand environmental challenges that the world faces in the 21st century. SERC is the Nation's leading research and education center dedicated to understanding ecological processes that sustain life on both land and the ocean. Over 70 percent of the world's population lives in the coastal zone, which includes the Earth's most biologically productive ecosystems, supports the majority of the world's fisheries and provides vast reserves of oil, gas and other non-living resources. The SERC Campus serves as a central campus for exploring the environment with other research that extends throughout the world. SERC educators provide rich content to the public based on their research through distance learning, web-based programs and on-site visits.

Recently, the institution concluded that they could improve their ability to research the environment with the help of a technological upgrade. "What we really needed was a wireless, mobile video conferencing solution so that we could bring the unit wherever our subject matter was," said SERC director of education Mark Haddon. SERC's research projects are comprised of a variety of outdoor studies, which include shoreline and marine life research. "We wanted to maintain the integrity of the program, which focuses on learning about Science outdoors, so we were particularly interested in bringing the students right to the scene of the research, for maximum impact and an enhanced educational experience," said Haddon. "The only way we could visualize this type of format was through video conferencing, but we were unsure about what would be involved from a product standpoint. We tried to set it up by using one of our old systems but it wasn't practical. A wireless, mobile solution is what was needed but we didn't know if such a system was available so we contacted our vendor IVCi and they configured and installed our Mobile Video Interactive Companion II (MVIC II). We use the system out in the water, specifically, on the boat and on the shore to study marine life; things like shells, crabs, plant life, etc. We also have future plans to begin extending our studies into the forest."

The MVIC II is a mobile, wireless video conferencing system that provides two-way, high-end quality and performance in a compact wireless mobile offering. The MVIC II can act as a stand-alone video conferencing system or work as an extension to existing video systems. The MVIC II system that was configured for SERC can be rolled about the campus freely and uses a Polycom unit as the video codec.

Even before the wireless video conferencing installation, SERC had always relied on technology to improve the way they worked and shared knowledge with other institutions. "We are, in essence, a content provider to schools that have invested in video conferencing technologies, continued Haddon. " It gives students from these schools the ability to visit the Smithsonian and learn all about different types of life forms found throughout our environment, without leaving their classrooms. The fact is that many school districts are looking for content providers with good equipment because it justifies usage and encourages more schools to get involved in video conferencing. Video conferencing has developed into an excellent way for schools to provide quality education for their students, regardless of where the subject matter is located."

SERC has been using video conferencing for ten years but the wireless feature opens up a new world of possibilities. "The great thing about our current usage of this technology is that we really have access to true 360 degree video conferencing," said Haddon. "We have the unobstructed ability to share what we see and hear in real time. I've never heard of anyone anywhere with this type of application."

Recent improvements by equipment manufacturers and enhancements to related technologies, such as IP networks, have made video conferencing more reliable and affordable. As a long-time user of video conferencing systems, Haddon is very pleased with the changes. "There's no question that the technology has gotten much better, said Haddon. "We no longer experience the types of connection problems we used to encounter. At one time, video conferencing was a very unreliable way to meet. Those issues are gone." Added Haddon, "We've also learned that it is very important to work with companies that are highly knowledgeable in this technical area. It's a specialized technology; therefore, you should only seek out specialists with the right experience and industry certifications."
