A Packed Audio Segment has no Media Initialization Section.
|
|
|
|
Each Packed Audio Segment MUST signal the timestamp of its first
|
|
sample with an ID3 PRIV tag [ID3] at the beginning of the segment.
|
|
The ID3 PRIV owner identifier MUST be
|
|
"com.apple.streaming.transportStreamTimestamp". The ID3 payload MUST
|
|
be a 33-bit MPEG-2 Program Elementary Stream timestamp expressed as a
|
|
big-endian eight-octet number, with the upper 31 bits set to zero.
|
|
Clients SHOULD NOT play Packed Audio Segments without this ID3 tag.
