Appendix C: Bandwidth and Video Size

Estimation

The frame rate of video transmitted from the device 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 form your
device.

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 device may be varying.

Audio streaming also takes bandwidth around 32kbps. Some xDSL/Cable modem
upload speeds could not even reach up to 128 kbps. Thus, you may not be able to
receive good quality video while also 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.
