RcEnable R/W Rate Control Enable
If this flag is set to 0, the value of register PictureQs is
used as a Quantization Step in whole sequence.
BitRate R/W Target Bit Rate in kilo bit per seconds (kbps)
This value is ignored if RcEnable = 0
Maximum allowed value is 32767 (0x7FFF)
InitDelay R/W Reference Decoder initial buffer removal delay in mili-
second (ms)
This value is ignored if RcEnable = 0
Maximum allowed value is 32767 (0x7FFF)
This bit is ignored if SliceMode bit is 0
In H.263 Mode with Annex K = 0, this bit is ignored
If SliceSizeMode is 0, macro-block number of one
slice must be set to this register
If SliceSizeMode is 1, encoded bit count of one slice
must be set to this register
This bit is ignored if SliceMode bit is 0
In H.263 Mode with Annex K = 0, this bit is ignored
