Appendix B: 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 from 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. 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.
