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.
