100 CONTROLLING THE BIT RATE OF STREAMING VIDEO AND AUDIO DATA It is possible to change the bit rate of the encoder. Since the settings of the encoder are not overwritten, the changed rate will return by turning on/off the encoder. ■Format ■Response ■Important Notice •"rate=(parameter value)&ch=(parameter value)"(Required) ■Item List Item Parameter name Parameter value Description Change the bit rate rate 01=1.5M Designate the bit rate to be changed. 02=3.0M 03=3.8M 04=4.6M 05=6.1M (150ms) 06=9.2M (150ms) 07=6.1M (100ms) 08=9.2M (100ms) 00=To the set value reset VIDEO IN connector number ch 01 - 04 Select one of the VIDEO IN connector of which the bit rate to be changed. ■Examples 1.
