Managing splice points for non-seamless concatenated bitstreams
First Claim
1. A method performed by a digital home communication terminal (DHCT), comprising:
- receiving a video stream in a transport stream from a headend by the DHCT, the video stream comprising a first message comprising first information from a splicer; and
controlling an overlap transition period via the first information from the splicer;
wherein controlling the overlap transition period includes;
controlling, via the first information, output of decoded picture buffer (“
DPB”
) pictures at the splice point of non-seamless concatenated bitstreams; and
controlling, via the first information, DPB space usage for the overlap transition period lasting a number of picture output times defined in the first information.

Abstract
Receiving a video stream in a transport stream comprising a plurality of compressed pictures, wherein information in the video stream includes plural data fields comprising: a first data field corresponding to a location in the video stream of a potential splice point, wherein the first data field identifies a location in the video stream after the location of the received information; a second data field corresponding to decompressed pictures yet to be output (DPYTBO) by a video decoder at the identified potential splice point (IPSP) when the video decoder decompresses the video stream, wherein the second data field is a number corresponding to the DPYTBO by the video decoder at the IPSP; and a third data field corresponding to pictures with contiguous output times (WCOT), wherein the third field corresponds to a set of pictures WCOT of the DPYTBO by the video decoder at the IPSP.

9. A method comprising:
-
transmitting a video stream in a transport stream from a headend to a digital home communication terminal (DHCT) coupled to the headend; controlling an overlap transition period via first information from a splicer at the headend; wherein controlling the overlap transition period includes; controlling at the DHCT, via the first information, output of decoded picture buffer (DPB) pictures at a splice point of non-seamless concatenated bitstreams; and controlling at the DHCT, via the first information, DPB space usage for the overlap transition period lasting a number of picture output times defined in the first information. - View Dependent Claims (10, 11, 12, 13)
