Full Description

This standard supports the splicing of MPEG-2 streams for the purpose of Digital Program Insertion,which includes advertisement insertion and insertion of other content types. An in-stream messagingmechanism is defined to signal splicing and insertion opportunities and it is not intended to ensureseamless splicing. As such, this recommendation does not specify the splicing method used orconstraints applied to the streams being spliced, nor does it address constraints placed on splicingdevices. This standard also supports accurate signaling of events in the stream.

A fully compliant MPEG-2 transport stream (either Multi Program Transport Stream or Single ProgramTransport Stream) is assumed. No further constraints beyond the inclusion of the defined cueingmessages are placed upon the stream.

This standard specifies a technique for carrying notification of upcoming Splice Points and other timinginformation in the transport stream. A splice information table is defined for notifying downstreamdevices of splice events, such as a network break or return from a network break. The splice informationtable, which pertains to a given program, is carried in one or more PID(s) referred to by that program'sProgram Map Table (PMT). In this way, splice event notification can pass through most transport streamremultiplexers without need for special processing.
