Appendix C: Bandwidth and Video Size
Estimation
The frame rate of video transmitted from the ICA-310 depends on connection bandwidth
between client and server, video resolution, codec type, and quality setting of server. Here is a
guideline to help you roughly estimate the bandwidth requirements for your ICA-310.
The required bandwidth depends on content of video source. The slow motion video will
produce smaller bit rate generally and fast motion will produce higher bit rate vice versa.
Actual results generated by the ICA-310 may be varying.
Image Resolution
160 x 120 (QQVGA)
320 x 240 (QVGA)
640 x 480 (VGA)
Note: Audio streaming also takes bandwidth around 5 kbps to 64kbps. Most
xDSL/Cable modem upload speeds may not even reach up to 128 kbps. Thus,
you may not be able to receive any video while streaming audio on a 128 kbps or
lower connection. Even though the upload speed is more than 128kbps, for
optimal video performance, disabling audio streaming will get better video
performance.
