Both ViewStation FX, and VS4000, have a tremendous amount of power. Polycom uses that power is two ways for video. At high bandwidths (512 kbps up to 1.922Mbps), it delivers TV quality, 60 fields video, for an outstanding video image and complete motion capture! The secret is capturing both fields, which comprise a frame. (For NTSC, there are 30 frames per second). By capturing both fields, the resolution is greatly heightened and the motion is captured much more accurately. The resulting image is amazingly brilliant!

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.
