Assistance for Processing Pictures in Concatenated Video Streams

摘要

Providing a video stream in a transport stream, the first video stream providing a plurality of compressed pictures and information, the information including plural data fields including: a first data field corresponding to a location in the video stream of a potential splice point, the value of the first data field identifies a location in the video stream after the location of the provided 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, the value of the second data field is a number corresponding to the DPYTBO; and a third data field corresponding to pictures with contiguous output times (WCOT), the value of the third field corresponds to a set of pictures WCOT of the DPYTBO.

主权项

1. A method, comprising:
receiving a video stream in a transport stream, the first video stream comprising a plurality of compressed pictures; and receiving information in the video stream, wherein the information includes plural data fields, the received information comprising: a first data field corresponding to decompressed pictures yet to be output (DPYTBO) by a video decoder at a potential splice point (IPSP) when the video decoder decompresses the video stream, wherein the value of the first data field is a number corresponding to the DPYTBO by the video decoder at the IPSP; and a plurality of second data fields, wherein each of the plurality of second data fields corresponds to a respective DPYTBO by the video decoder at the IPSP, wherein the number of second data fields in the plurality of second data field equals to the value of the first data field, and wherein the value of each of the second data field indicates how each of the respectively corresponding DPYTBO at the IPSP is to be output by the video decoder.
