more details and moving fast, then it takes up more bandwidth to transmit, and
reversely it occupies less bandwidth. When the setting goes with constant bit
rate, then the image is transmitted under a constant bandwidth.
Bit Rate Upper Limit:
You have to set the upper limit of bit rate if “vbr” is
selected; the stream size will be fixed if “cbr” is selected and the stream size is
defined in the “Bit Rate Upper Limit”. For major stream, the bit rate upper limit
can be
1000Kbps ~10000Kbps; for minor stream, the bit rate upper limit can be
256Kbps ~2000Kbps.
