2-4 Sun MediaCenter Server Administrator’s Guide • December 1997
2.3.2 closed_gop
The closed_gop is a one-bit flag that indicates the nature of the predictions used in
the B-pictures immediately following the first coded I-frame following the group-of-
pictures header. The closed_gop must be set to 1 to indicate that these B-pictures
have been encoded using only backward prediction.
2.3.3 payload_unit_start_indicator
For an MPEG-2 Transport Stream, the first MPEG-2 transport packet following a
splice point must have the payload_unit_start_indicator set, and the packet must
contain a payload.
2.3.4 adaptation_field_control
For an MPEG-2 Transport Stream, the first MPEG-2 transport packet following a
splice point must have the adaptation_field_control set to indicate an adaptation
field as well as payload (value of 11).
2.3.5 random_access_indicator
For an MPEG-2 Transport Stream, the first MPEG-2 transport packet following a
splice point must have the random_access_indicator set to 1.
2.3.6 PCR_flag
For an MPEG-2 Transport Stream, the first MPEG-2 transport packet following a
splice point must have the PCR_flag set to 1, and must contain the PCR value in the
adaptation field.
Note – The above requirements for splice points apply to the video stream. If the
bit stream contains audio, and/or other elementary streams, the requirements apply
to those streams as well.
