Chapter 9. Bandwidth 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 for 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.
