摘要： A system, method, and apparatus for time stamping compressed video data is disclosed. A delay parameter is generated and can be encoded with the compressed video, representing the number of picture delay between the decoded sequence and the presented sequence . The presentation time stamp is associated with each of the pictures. The presentation time stamp is a function of the delay parameter and other parameters associated with picture associated therewith.

摘要： To extract a sub-bitstream from a 3-dimensional video (3DV) bitstream, a device determines a texture target view list that indicates views in the 3DV bitstream that have texture view components that are required for decoding pictures in a plurality of target views. The target views are a subset of the views in the bitstream that are to be decodable from the sub-bitstream. In addition, the device determines a depth target view list that indicates views in the 3DV bitstream that have depth view components that are required for decoding pictures in the plurality of target views. The device determines the sub-bitstream based at least in part on the texture target view list and the depth target view list.

摘要： A transmitting method includes: inputting, per unit time, a plurality of transfer packets less than or equal to a predetermined number; and transmitting, per the unit time, the plurality of transfer packets that have been input, in a state where definitions compliant with a receiving buffer model are satisfied (S2301). Each of the plurality of transfer packets includes a variable-length packet header and a variable-length payload. The definitions compliant with the receiving buffer model are predetermined for guaranteeing a buffering operation of a receiving device, and specify converting a first packet into a second packet and outputting the second packet from a buffer of the receiving device at a predetermined extraction rate. The first packet is included in the transfer packets received and includes a variable-length packet header and a variable-length payload. The second packet has a fixed-length packet header that is extended.

摘要： The present invention relates to a broadcast signal transmitting device for transmitting broadcast signals, a broadcast signal receiving device for receiving broadcast signals, and a method for transmitting and receiving broadcast signals. The broadcast signal receiving device, according to the present invention, comprises: a receiving unit for receiving a three-dimensional television (3DTV) service video stream, which is frame-compatible with a video component, and broadcast signals which include signaling information for signaling the video stream, wherein the signaling information includes a first piece of information for indicating whether the video stream is in a frame-compatible 3DTV video format or a high definition television (HDTV) format, service type information which indicates whether a service type of the video stream is a high-efficiency video coding (HEVC) service, and a plurality of component descriptors which indicate the type of the HEVC service to the video stream; a signaling information processing unit for identifying the type of the video stream, based on the signaling information; and an output unit for outputting the video stream in the 3DTV video format or the HDTV video format, based on the type of the video stream.

摘要： Video parameter storage and processing techniques with MPEG-4 file format are described. In one or more implementations, techniques are described in which sequence and parameter sets are specified in-band with collections of pictures of video as the default option. Techniques are also described in which different parameter set identifiers (IDs) are specified for the collections within the video. Techniques are also described in which maximum clip parameters are specified in a sample description box. Further, techniques are described in which parameter sets are inserted at a beginning of sample data when an access unit delimiter (AUD) network access layer (NAL) unit is not present or are inserted after the AUD NAL unit in the video when present.
