Patent ID: 7630442

Claim:
A receiving apparatus comprising: a media demultiplexer, for demultiplexing a multiplex stream generated by a media multiplexer into packets of coded video streams and packets of coded audio and data streams; an error detector for decoding an error detecting code contained in each of said packets to obtain an error detection result; and a video decoder for decoding packets of coded video streams into video packets based on said error detection result for each coded video stream concerned, wherein each of said coded video streams is composed of plural pieces of compressed block coded data, said plural pieces of compressed block coded data are composed of plural kinds of data elements, said data elements of the same kind are arranged in succession over plural blocks, and said coded video stream is divided, at the point of change in the kind of said data elements arranged in succession, into said each packet, said each packet being added, for each of said divided video coded streams, with an error detecting code for obtaining said error detection result, wherein said plural kinds of data elements include motion vector data and texture information, such that motion vector data is provided in separate packets than texture information in each of said coded video streams, wherein said video decoder determines a position of a decoding error based on the error detection result and selectively performs error concealment based on the position of the decoding error.
