Appendix C --- Bandwidth Estimation
The frame rate of video transmitted from the ICA-151 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-151.
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-151 may be varying.

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.
