The second benefit of the increased horsepower is the increased utilization of ITU defined Annexes that are the compression tips and tricks used to optimize the limited bandwidth for delivering the best possible picture possible. At Polycom, we emphasize picture quality above all other aspects of video. We also realize the importance of smooth motion handling. Because we are not willing to comprise on either, we cannot sacrifice the overall quality of the picture to deliver 30 frames per second at lower bandwidths than 336 kbps.
Audio Quality: The audio performance of a video communication is critical to the user's perception of a good videoconference. If the audio signal breaks up, or becomes out of sync with the speaker's lips, the videoconference is not contributing to clarity of communication.
Polycom supports numerous algorithms ranging in capability from G.711, (low bandwidth (7 kHz) and high bit rate (48, 56, 64 kbps)), to G.722, (high bandwidth (7 kHz) and high bit rate (48, 56, 64). The ability to automatically adjust the quality of audio is important when supporting low bandwidth calls. When more bandwidth is available, the codec wants to use more bandwidth to get better audio.
Streaming: Streaming is the process of sending audio and video over a local area network (LAN) from one source to many viewers. You can use streaming to conduct live broadcasts of meetings or events.
For example, employees can view a live speech from your company's CEO. The ViewStation FX allows on-the-fly streaming capability! It's as easy to turn on as placing an audio call while in a videoconference.
