Table 5.11: H.264/AVC Encoder Option Descriptions (continued)
Selected Item Options Description
Bitrate:
Defines the maximum bitrate
generated by the video encoding
module. This can be set to be
between 0.256 Mbit/s and a
maximum of 10.0 Mbit/s for
SD.
1 Mbit/s to 20 Mbit/s for HD The menu system could reduce this maximum if the MUX bitrate is lower
than 5.0 Mbit/s. The bitrate is measured over a period of 1.0 second.
CPB Size: 0.08 Mbit/s to 10 Mbit/s (SD)
0.32 Mbit/s to 15 Mbit/s (HD)
Copyright:
Controls the Copyright flag in the
bitstream. If set to On the bitstream is shown to be protected by copyright.
GOP Length:
Defines the maximum distance in
steps of video frames between
two consecutive I frames in the
encoded bitstream. 12 to 250 frames As the video encoding module inserts I frames when it will improve the
encoding quality, the time between two I frames is often less.
IP P frames are used between the intra-coded I frames.
IBP A single B frames can be inserted into the sequence.
IBBP Two B frames can be inserted into the sequence.
IBBBP Three B frames can be inserted into the sequence
GOP Structure:
Sets the GOP structure.
This sets what type of frames are present and the order of the frames in the stream.
I Frame Intvl:
Displays the maximum time in
seconds between two
consecutive I frames in seconds. This is calculated from the video frame rate and the GOP length specified
above.
MCTF: Enables Motion Compensated Temporal Filtering. (SD Only)
Standard The default mode should be used unless channel change is an issue.
Low Delay Standard mode but with a smaller video decoder buffer.
Mega Low Delay Standard mode but with a further reduced video decoder buffer.
Mode:
Defines how the maximum
decoder buffer size in terms of
time.
Seamless Var. Delay VBR mode primarily for use in statmux system.
Original:
Controls the setting of the
Original flag in the bitstream. If set to On the bitstream will be signaled as an original, if set to Off the
bitstream will be signaled as a copy of an original bitstream.
PCR on Video PID:
Defines whether PCR
timestamps are included into the
video elementary stream.
per Sequence Defines all random access point. PES:
Defines where PES headers are
placed.
per Frame Defines each frame.
PID:
Defines the PID used for the
elementary stream in the
transport stream. PIDs 32 to 8190 are
available for use. This option will only be visible if the output has been selected to be TS. To
be DVB compliant, PIDs below 32 are reserved. In the event of a clash,
one of the PIDs will be changed by the Encoder’s internal checking
algorithm.
Pre-Proc Version:
Shows the version of the code in
the pre-processing software. This is for status only and cannot be changed.
