no. 1 example

[0252] FIG. 4 is a diagram showing an example of the overall configuration of the first embodiment of the transmission / reception system to which the present invention is applied.

[0253] This transmission / reception system 40 includes a transmitter 41 and a receiver 42 . The transmitter 41 is, for example, a device such as a broadcasting station that transmits a plurality of TS packets, and the receiver 42 is, for example, a home device such as a home set-top box.

[0254] In the first embodiment, the transmitter 41 encodes an audio stream and transmits the resulting TS packets, and the receiver 42 receives and decodes the TS packets and obtains the resulting audio stream.

[0255] FIG. 5 is a block diagram showing an example of the configuration of the transmitter 41 in FIG. 4 .

[0256] The transmitter 41 includes: an input section 71, an audio encoder 72, a basic buffer 73, extension buffers 74-1 to 74-n, an extraction information adding section 75, a PES packetizing secti...

[0482] Then, the second embodiment of the transmission / reception system to which the present invention is applied is described.

[0483] Fig. 29 shows an example of the second embodiment of the transmission / reception system to which the present invention is applied. Limitations in the case where the transmitter 511 encodes an audio stream by using MPEG (Moving Picture Experts Group) 2-TS (Transport Stream) (hereinafter referred to as MPEG2-TS) technology are described with reference to FIG. 29 .

[0484] The transmitter 511 is a device at a place such as a broadcasting station for transmitting a stream including a plurality of MPEG2-TS packets. For example, the transmitter 511 encodes a video or audio stream by using MPEG2-TS technology when assuming a virtual receiver 512 at the receiving end, and transmits the encoded stream to an actual receiver (not shown).

[0485] The second embodiment will be described assuming that the transmitter 511 encodes an audio stream into TS p...

[0583] Next, a third embodiment of the transmission / reception system to which the present invention is applied is described.

[0584]Fig. 40 shows an example of the configuration of the third embodiment of the transmission / reception system to which the present invention is applied. Limitations in the case where the transmitter 811 encodes an audio stream using MPEG (Moving Picture Experts Group) 2-TS (Transport Stream) (hereinafter referred to as MPEG2-TS) technology are described with reference to FIG. 40 .

[0585] The transmitter 811 is a device for transmitting a stream including a plurality of MPEG2-TS packets in a place such as a broadcasting station. For example, the transmitter 811 encodes a video or audio stream by using MPEG2-TS technology when assuming a virtual receiver 812 at the receiving end, and transmits the encoded stream to an actual receiver (not shown). The transmitter 811 also encodes (multiplexes TS packets) the stream by using MPEG2-TS technology when ...

Abstract

There are provided a data structure, an information processing device, an information processing method, a transmission device, a transmission method, a multiplexing device, a multiplexing method, and a program enabling a reception side to surely decode an audio stream having a basic stream and an extended stream and subjected to hierarchical encoding. A TS packetization unit (537) packetizes the basic audio stream and the extended audio stream into TS packets and a control unit (535) controls timing of transmission of the TS packets. Here, the control unit (535) controls timing of multiplexing the TS packet at such a timing that an elementary buffer of a virtual reception device will not overflow or underflow. The present invention may be applied to a multiplexing device for multiplexing TS packets.

Description

technical field [0001] The present invention relates to a data structure, an information processing device, an information processing method, a sending device, a sending method, a multiplexing device, a multiplexing method, and a program, and more particularly, relates to a method for ensuring that a receiving end decodes each A data structure of a hierarchically encoded audio stream including a basic stream and an extended stream, an information processing device, an information processing method, a transmitting device, a transmitting method, a multiplexing device, a multiplexing method, and a program. Background technique [0002] A method of packetizing and encoding (multiplexing) video and audio streams includes MPEG (Moving Picture Experts Group) transport stream technology (hereinafter referred to as MPEG2-TS technology). [0003] FIG. 1 is a schematic diagram of restrictions in a case where a transmitter 1 performs encoding using MPEG2-TS technology. The transmitter ...
