摘要:
A multiplexing apparatus for multiplexing audio data into transport stream (TS) packets includes a first encoding section encoding the audio data by a first encoding method; a second encoding section encoding the audio data by a second encoding method, which is a variable-length encoding method and which differs from the first encoding method, for attaching a timing value indicating a timing used when audio data is decoded in units of predetermined audio data; a packetization section packetizing the audio data encoded by the first encoding section and the audio data encoded by the second encoding section into TS packets and for attaching the same ID to a plurality of packetized TS packets; a determination section determining a TS packet to be multiplexed from among the plurality of TS packets packetized by the packetization section; and a multiplexing section multiplexing the TS packet determined by the determination section.

The present invention relates to a multiplexer, a multiplexing method, a program, and a recording medium, whereby TS packets encoded with different encoding methods can be multiplexed. In the event of multiplexing each TS packet of a BS audio TS 173 wherein a BS audio ES 171 encoded with a first encoder is subjected to TS packetizing, and each TS packet of an HQ audio TS 183 wherein an HQ audio ES 181 encoded with a second encoder is subjected to TS packetizing, a control unit assumes a first virtual decoder capable of decoding a BS audio ES alone, and a second virtual decoder capable of decoding an HQ audio ES alone, and determines TS packets to be multiplexed based on an elementary buffer of each virtual decoder, a data transfer rate for the elementary buffer, and multiplexing constraints for random access. The present invention can be applied to a multiplexer configured to multiplex TS packets.

The present invention relates to a data structure, an information processing apparatus, an information processing method, a transmitting apparatus, a transmitting method, a multiplexing apparatus, a multiplexing method, and a program that ensure a receiving side to decode hierarchically coded audio streams each including a base stream and an extension stream. A TS packetizing section 537 packetizes each of base and extension audio streams into TS packets. A control section 535 controls TS packet transmitting timing. At this time, the control section 535 control the TS packet transmitting timing with timing that an elementary buffer of a virtual receiver is prevented from overflowing and underflowing. The present invention is applicable to a multiplexing apparatus that multiplexes TS packets.

The present invention relates to a recording apparatus, a recording method, a playback apparatus, a playback method, a program, and a recording medium in which random access playback of TS of audio data encoded using different encoding methods can be performed. A controller obtains PTS from TS, and sets a BS audio TS packet 261-1 as an entry point when an HQ audio TS packet 271-1 having the same PTS exists after the BS audio TS packet 261-1 in the TS. Further, the controller generates EP_map based on the PID of the BS audio ES and the HQ audio ES, the source packet number of the BS audio TS packet 261-1 set as the entry point, and the PTS.

摘要:
The present invention relates to a playback apparatus and a playback method which allow setting of picture-in-picture display, a program, a program storage medium, a data structure, and a recording-medium manufacturing method. Pip_metadata states information required for the picture-in-picture display. Pip_horizotal_position indicates, on the frame of a primary video, an X coordinate at the upper left corner of a sub display screen on which a secondary video is displayed. Pip_vertical_position indicates, on the frame of the primary video, a Y coordinate at the upper left corner of the sub display screen on which the secondary video is displayed. Pip_scale states information indicating the size of the sub display screen on which the secondary video is displayed. For example, pip_scale states the size ratio of the secondary video to the primary video, the scale ratio of the secondary video to its original image, or information indicating how many pixels is included in the sub display screen in each of the vertical direction and horizontal direction. The present invention is applicable to playback apparatuses.

The present invention relates to a playback apparatus, a playback method, a program, a recording medium, a data structure, and a manufacturing method for a recording medium in which content to be played back can be switched between streams different from a main stream. A PlayList includes Main path for referring to Video and Audio within a main TS, Sub Path-A for referring to Secondary Video and Secondary Audio in a sub TS, and Sub Path-B for referring to Audio in a sub TS. STN_table( ), which is information for selecting Video and Audio in a clip AV stream file-0 as PlayItem-1 and selecting Secondary Video and Secondary Audio in clip AV stream file-1, or Audio in clip AV stream file-2 as SubPlayItem (SPI) which is simultaneously played back with PlayItem-1, is used. The present invention is applicable to a playback apparatus.
