Abstract

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.

Claims

exact text as granted — not AI-modified
At least the following is claimed: 
     
         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.   
     
     
         2 . The method of  claim 1 , wherein the value of one of the plurality of the second data fields corresponds to foregoing the output of the picture corresponding to the respective second data field. 
     
     
         3 . The method of  claim 1 , wherein the value of one of the plurality of the second data fields corresponds to allowing the output of the picture corresponding to the respective second data field to be repeated once. 
     
     
         4 . The method of  claim 2 , wherein the value of another of the plurality of the second data fields corresponds to allowing the output of the picture corresponding to the respective second data field to be repeated twice. 
     
     
         5 . The method of  claim 1 , wherein the value of one of the plurality of the second data fields corresponds to allowing the output of the picture corresponding to the respective second data field to be repeated one of more than once or until the output of next picture to be output from the DPYTBO. 
     
     
         6 . The method of  claim 1 , wherein the received information in the video stream is provided in a message in the video stream. 
     
     
         7 . The method of  claim 1 , wherein the received information further comprises of a third data field wherein the value of the third data field represents a number of pictures. 
     
     
         8 . The method of  claim 1 , wherein the received information further comprises of a fourth data field, wherein the fourth data field identifies the last picture in a set of pictures with contiguous output times of the DPYTBO. 
     
     
         9 . The method of  claim 1 , wherein the received information further comprises of a fifth data field, wherein the fifth data field provides an initial delay of a compressed picture buffer at the IPSP when the video stream is decompressed. 
     
     
         10 . The method of  claim 1 , wherein the received information further comprises of an sixth data field, wherein the sixth data field provides an output picture delay of a decoded picture buffer at the IPSP when the video stream is decompressed. 
     
     
         11 . The method of  claim 1 , wherein the received information further comprises of a seventh data field, wherein the seventh data field provides an output picture delay of a decoded picture buffer at the IPSP when the video stream is decompressed. 
     
     
         12 . A method, comprising:
 providing a video stream in a transport stream, the first video stream comprising a plurality of compressed pictures; and   providing information in the video stream, wherein the information includes plural data fields, the provided 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.   
     
     
         13 . The method of  claim 12 , wherein the value of one of the plurality of the second data fields corresponds to foregoing the output of the picture corresponding to the respective second data field. 
     
     
         14 . The method of  claim 12 , wherein the value of one of the plurality of the second data fields corresponds to allowing the output of the picture corresponding to the respective second data field to be repeated once. 
     
     
         15 . The method of  claim 13 , wherein the value of another of the plurality of the second data fields corresponds to allowing the output of the picture corresponding to the respective second data field to be repeated twice. 
     
     
         16 . The method of  claim 12 , wherein the value of one of the plurality of the second data fields corresponds to allowing the output of the picture corresponding to the respective second data field to be repeated one of more than once or until the output of next picture to be output from the DPYTBO. 
     
     
         17 . The method of  claim 12 , wherein the provided information in the video stream is provided in a message in the video stream. 
     
     
         18 . A method, comprising:
 providing a video stream in a transport stream, the first video stream comprising a plurality of compressed pictures; and   providing information in the video stream, wherein the information includes plural data fields, the provided 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 that provide information corresponding to the relative output times of the DPYTBO by the video decoder at the IPSP.   
     
     
         19 . The method of  claim 18 , wherein the provided information conveys repeating the output of at least one of the DPYTBO by the video decoder at the IPSP. 
     
     
         20 . The method of  claim 18 , wherein the provided information conveys a gap in output of the DPYTBO by the video decoder at the IPSP.
