Video Conferencing Rooms

Videoconferencing equipment does require room . Video conferencing rooms are rooms facilitated to accommodate meetings between people in different locations or countries. These rooms, along with videoconferencing public rooms, enable people to combine the technology of both sound and vision to interact with each other. A video conferencing room should emulate the traditional conference

Lighting: Lighting in the videoconferencing space is key to delivery of a good quality image. The best lighting to use is diffuse fluorescent lighting. It is important to minimize shadows in videoconference rooms and to create an evenly lit environment so that all participating people can be captured by the camera. To enhance the appearance of skin tones and to minimize annoying shadows, lights with a color of 3500 Kelvin should be used.

It is best for the room to not have any windows facing outside as incoming light can interfere with any light settings and arrangements.

Effort should be put into establishing uniform lighting in the room, and using curtains or opaque blinds to cover the windows will help. Another often overlooked issue is the color of clothing that the speakers are wearing. They should be pale colors, which do not have a high degree of contrast in comparison to the human face colors. Very dark clothing colors show even darker and in fact may create an unattractive image of the speaker.

Interior Room Design: When considering the interior design of the videoconferencing space, the primary goals should be to make the room as comfortable as possible, de-emphasizing the technology in the room and making the user interface to the system uniform and predictable.
Specific colors are recommended for backgrounds and wall covering to enable better recognition of attendees without straining the capture capabilities of the video camera. A neutral non-white color such as a grey tone is the best color for the walls in video conferencing rooms. Light grey, blue or beige can also be used. There should be no patterned wallpaper or items with busy colorful prints in the area that is to be filmed. This can also cause disturbance.

When considering furniture and walls be aware of color and physical characteristics that may make your video or audio input have to work harder.

Audio System: Audio quality is the most important factor for a successful video conferencing experience. If you cannot properly hear what is being said, there is no reason to have a meeting, therefore good acoustics are paramount.
The audio system has four major components: one or more microphones (and mixer if required); the loudspeaker system; the video codec and digital phone hybrid that handles the signal processing allowing full duplex (two way) conversation and transmission/reception of the signals; and the acoustic echo cancellation (to prevent the source station hearing itself amplified and re-transmitted from the receive location). The performance of the entire audio chain is directly tied to the room acoustics. The performance of the echo cancelling is directly tied to the decay of sound in the room, and the quality of microphone pickup is likewise affected by early reflections and reverberation.

It is also important to isolate the videoconferencing public rooms from external noise sources like fans and duct work from heating and cooling systems, water pipes, office machines, telephones, and street noise.

Microphones

Microphone placement plays an important part of the sense of distance between the talker and the receiving station. . A microphone has to be placed at least six feet from the system speakers. Another microphone is placed ten feet from the first. A microphone cannot be farther than seven feet from a speaking person to ensure maximum audio quality and no more than three microphones can be used in a room .

Multipoint Video Conferencing

Multipoint video conferencing allows participants at more than two sites to engage in real-time communication by means of a Multipoint Control Unit (MCU) to which all the participants connect.
This is a bridge that interconnects calls from several sources (in a similar way to the audio conference call). All parties call the MCU unit, or the MCU unit can also call the parties which are going to participate, in sequence. There are MCU bridges for IP and ISDN-based videoconferencing. There are MCUs which are pure software, and others which are a combination of hardware and software. An MCU is characterised according to the number of simultaneous calls it can handle, its ability to conduct transposing of data rates and protocols, and features such as Continuous Presence, in which multiple parties can be seen onscreen at once

MCUs can be stand-alone hardware devices, or they can be embedded into dedicated VTC units

Some systems are capable of multipoint conferencing with no MCU, stand-alone, embedded or otherwise. These use a standards-based H.323 technique known as "decentralized multipoint", where each station in a multipoint call exchanges video and audio directly with the other stations with no central "manager" or other bottleneck.

The key difference in multipoint versus "normal" video conferencing is the fact that there are multiple participants at multiple locations rather than a single interaction between two webcams or two digital video cameras communicating directly through conferencing software.

Video conferencing is about making far-flung connections without the need to travel and conducting those interactions effectivel. With continued improvement in equipment, multipoint video conferencing will become an increasingly influential communication application.

There is an increasing demand for multipoint video teleconferencing for a number of reasons. Not only does it overcome the expense and delays caused by travel, but these meetings tend to be briefer and more focused than face-to-face encounters and thus more productive. Busy executives can budget their time more effectively when meeting with clients or employees and, compared to the cost of travel, establishing facilities for a multipoint video conference is much more cost effective.

Many systems now offer a built-in video conferencing bridge, which has made multipoint conferencing increasingly affordable. As multipoint video conferencing continues to grow in popularity, however, and systems with build-in bridges become more refined, prices will undoubtedly drop.

Planning a multipoint conference is similar to Planning for 2-Way Video. Multipoint vidconfonferences are more complex because you have to manage more sites and more people. Here are some suggestions for a successful multipoint videoconference:
Limit the number of sites to 3 or 4, especially if you're new to multipoint videoconferencing. Make sure that you have the voice number of each of the participants.

For important events, use your cell phone and stay connected throughout the event. That way you can monitor what is going on and make strategic changes to camera position, lighting, and so on without interrupting the flow of the event.
For large groups, it's helpful to have a "speaker's podium." With careful planning, you can switch views during the event from the whole group to the podium and back.

It's nice to have auxiliary microphones and cameras if possible. A wireless microphone can be passed around for audience participation. An auxiliary camera can be used for the podium and the regular camera and monitor can face the audience.

Video Conferencing: The Sony PCS set-top videoconferencing systems incorporate the most advanced IT and worldwide-proven AV technologies into a compact and stylish two-piece body. They're ideal for engaging in simple, immediate, and face-to-face communication with your staff or to make critical project decisions. The PCS Set-top systems provide effective data-sharing capabilities and bring superb acoustic quality into videoconferencing applications for more natural sound clarity.

Video conferencing
Video conferencing over The Internet is a new enabling technology for a number of applications in education, research, collaboration and day-to-day communication.
Video conferencing is a powerful tool and provides a virtual meeting environment that gives the benefit of real meeting. There are various kinds of conferences held using a video conferencing information system. Depending on the nature of the conference it becomes important to
plan the video conferencing information system schedule. It becomes very important to check the requirements for smooth progress of the meeting.A videoconference can be annual meeting of the organization or a product launch or it could be a virtual training session. The duration can vary from few minutes to hours. The long meetings on video conferencing has to be smooth and error free, no one likes distorted audio and video nor do they like any interruptions in between something crucial.

Long duration conferences need to be more comfortable, error free and interesting to hold people's attention for longer period. If the time involved is long it needs one has to be more cautious for smooth running of the system and the presentation should not become a nightmare for you.
Distance education and traditional classroom courses can benefit tremendously from this new, reliable and affordable means of interactive two-way communication.

The Videoconferencing for Learning website supports effective and educational uses of videoconferencing by providing basic information about the technology and instructional applications as well as resources to help you find and collaborate with other videoconferencing teachers, librarians, and content providers.

Tips for a Successful Video Conference Presentation
Know The Environment: Make acquainted yourself with the video conferencing system and place. For smooth running of the presentation and to make it effective it is essential know the environment. You need to know whether you have team member who are attending the conference for the first time. They need to be guided and trained in advance.

Other Participant Contact Details: You should have all the details so required for the conference of other participants of the conference in different locations. You should take technical support if so required while dialing out to start your conference.

Presentation Content: The materials that you need during the videoconference should be checked in advance, if you have soft copy of the materials in floppy or CD then load them on the PC and get yourself familiar with its usage. If you have uploaded it on the Internet then download and save it on your data PC.

Arrive on Time: Try to be at the venue some time before the videoconference start, this ensures you to check all the required peripherals, last minute settling in and checking the materials so required. All the people who will be attending the conference should be well settled and ready with their prerequisites. Position everyone in a manner so that everyone can be viewed as clearly as possible. Check the microphones and test the sound clarity and quality.

Video Conferencing

Image quality: Better image quality means more realistic conferences, with every participant clearly visible. Ultimately, subjective quality is limited by resolution a measure of the number of pixels making up a picture. For comparison, a modern notebook PC screen can offer a resolution of 1024 x 768 or even higher. Higher image resolutions also allow documents and diagrams from a connected computer to be seen more clearly by other conference participants but higher resolutions demand higher data rates. Sony systems such as the PCS-G70NP support video image qualities as high as 4CIF roughly equivalent to standard definition television broadcasts

Frame Rates: the number of images displayed per second has a dramatic effect on the quality and intelligibility of any videoconference. Low-cost webcam systems are often limited to just a few frames per second. This results in jerky, unnatural looking pictures that can be a distraction during a conference, particularly when the picture isn't smoothly synchronised with what the speaker is saying.

Using latest coding methods, Sony systems such as the PCS-G70NP support frame rates of up to 30 fps, or up to 50 interlaced fields (alternately scanned half frames) per second. Sony uses a range of QoS features including Real-time ARQ (Automatic Repeat reQuest), ARC (Adaptive Rate Control) and FEC (Forward Error Correction) to optimise frames rates plus audio quality under a wide range of real-world network conditions

Compression formats: All videoconferencing systems send video and audio across IP network connections or ISDN phone links as a stream of digitised data. There are several internationally-agreed standards for compressing data to deliver optimum sound and picture quality for a given bit-rate. The high efficiency of current standards such as H.264 now enables the transmission of high quality video and high bandwidth audio right up to High Definition

QOS: Frozen picture frames and annoying audio glitches: they're symptomatic of lost or degraded data packets sent over IP networks. It's a common problem, and congested networks or limited bandwidth can seriously impair the Quality of Service (QoS) enjoyed by videoconferencing users. Sony PCS Series videoconferencing systems use a range of QoS features including Real-time ARQ, ARC and FEC to optimise audio and picture quality under a wide range of real-world network conditions
