63. 例)Media segments の運用規則
Transport Stream segments MUST contain a single MPEG-2 Program.
There SHOULD be a Program Association Table (PAT) and a Program Map
Table (PMT) at the start of each segment. A segment that contains
video SHOULD have at least one key frame and enough information to
completely initialize a video decoder.
A Transport Stream or audio elementary stream segment MUST be the
continuation of the encoded media at the end of the segment with the
previous sequence number, where values in a continuous series, such
as timestamps and Continuity Counters, continue uninterrupted -
unless the media segment was the first ever to appear in the Playlist
file or has an EXT-X-DISCONTINUITY tag applied to it.
Clients MUST ignore private streams inside Transport Streams that
they do not recognize.
