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.
