AC3 Audio Bitrate Setup
Audio Bitrate: This monitor displays the bitrate on the AC3 audio.
Advanced Video Settings
GOP Size (15 to 60): This parameter allows the user to set the GOP (Group of Pictures) size of the
compressed stream.
IDR Pictures: This parameter allows the user to enable/disable insertion of IDR (Instantaneous
Decoder Refresh) frames. An IDR frame is a special type of I-frame in H.264. An IDR frame specifies
that no frame after the IDR frame can reference any frame before it. This makes seeking the H.264
frames easier and more responsive for the decoder.
Latency Mode: This parameter allows the user to set the latency mode. Possible values are ULL
(ultra low latency) and Low.
I-P Interval: This control allows the user to set the number of intervals between the I and P frames,
range is 1 to 4.
Closed GOP: This parameter allows the user to set the closed GOP. Possible values are open or
closed. A closed GOP cannot contain any frame that refers to a frame in the previous/next GOP.
Closed GOP only applies and visible when MPEG 2 is selected as codec.
Encoder Controls Advanced
SCTE 35: These parameters allow the user to set the SCTE 35 PID number, have the PID enable or
disable and select the max bitrate in kbps. If the max bitrate is exceeded the PID will be limited and
only SCTE 35 packets will be dropped so other stream components are unaffected. The SCTE 35
PID is generated by receiving SCTE 104 data or GPI triggers.
VANC: These parameters allow the user to set the VANC (SMPTE 2038) PID number, have the PID
enable or disable and select the max bitrate in kbps. If the max bitrate is exceeded the PID will be
limited and only Control Data packets will be dropped so other stream components are unaffected.
