摘要： A digital broadcast system is disclosed. The digital broadcast system including a transmitter, a receiver, and a method for transmitting and receiving a DTV signal comprising main service data and mobile service data multiplexed with the main service data. The DTV signal results from generating a second data by de-interleaving a first data group by a DTV transmitter.

摘要： A method and device for error concealment in a video sequence. When there is a scene transition (126) in the video sequence and there is an error in a picture belonging to the scene transition, an error concealment procedure based on the type of scene transition is used to conceal the error (136). Information about the type of the scene transition is provided to a video decoder in a supplemental enhancement information message. If the scene transition is a gradual scene transition, a spatio-temporal error concealment algorithm is used to concel the picture. If the scene transition is a scene cut and only a part of the picture is lost or corrupted, a spatial error concealment is used to conceal the lost or corrupted part of the picture. If a whole picture belonging to the scene cut is lost or corrupted and the picture starts a new scene, it is not concealed.

摘要： A system and method for recovering lost/damaged attribute data in a bitstream of encoded data comprising attribute data and encoded sample data is disclosed. The decoded neighboring data 445 is retrieved and lost/damaged attribute data is estimated using the encoded sample data, the decoded neighboring data, and available attribute data 465. In one embodiment, this is used in the transmission of video signals over a potentially lossy communications channel.

摘要： A system and method for recovering damaged data in a bitstream of encoded data (1705) is disclosed. In one embodiment, the encoded data is received and a plurality of candidate decoding (1710) are generated. An evaluation measurement is generated for each of the plurality of candidate decoding (1715). A candidate decoding to decode the bitstream of encoded data (1720) is selected dependent on the evaluation measurement. In one embodiment, this is used in the transmission of video signals over a potentially lossy communications channel.

摘要： A prediction image generator (108) generates a prediction image signal (212) according to the selected combination of reference image number and prediction parameter. A variable length encoder encodes orthogonal conversion coefficient information concerning prediction error signal for an input moving picture signal (100) and index information indicating related combination. An independent claim is also included for moving picture coding/decoding method.
