Abstract
A content distribution device includes data output means for outputting encoded data and transmission means for transmitting encoded data which is outputted from the data output means. The data output means outputs encoded data obtained by hierarchical encoding as the encoded data. The transmission means transmits at least a part of data of at least one layer among the encoded data obtained by the hierarchical encoding.
Claims56
A contents distributing apparatus, comprising
- a data output device that outputs encoded data;
- a plurality of transmitters that transmits the encoded data outputted from the data output device;
- and
- a computer that controls at least one of the data output device and the plurality of transmitters, wherein:
- the data output device outputs data encoded by hierarchical encoding as the encoded data;
- each of the plurality of transmitters transmits at least a part of data of at least one layer among the data encoded by the hierarchical encoding.
A contents receiving apparatus, comprising:
- a plurality of receivers that receives device for receiving encoded data transmitted by a plurality of transmitters;
- a device that receives the encoded data received by each of the plurality of receivers, and discriminates and separates individual encoded data units therefrom;
- and
- a reconstruction device which extracts encoded data received without a transmission error and a fault from the discriminated and separated encoded data, and reconstructs and outputs encoded data from the extracted encoded data;
- and
- a computer that controls at least one of the plurality of receivers, the device and the reconstruction device.
A contents transmitting/receiving system, comprising a contents distributing apparatus, a contents receiving apparatus, and a communication network that connects the contents distributing apparatus and the contents receiving apparatus, wherein:
- the contents distributing apparatus comprises
- a data output device that outputs encoded data;
- a plurality of transmitters that transmit at least a part of data of at least one layer among the data encoded by the hierarchical encoding outputted from the data output device;
- and
- a first computer that controls at least one of the data output device and the plurality of transmitters;
- and
- the contents receiving apparatus comprises
- a plurality of receivers that receive device for receiving encoded data transmitted by the a plurality of transmitter;
- a device that receives the encoded data received by each of the plurality of receivers, and discriminates and separates individual encoded data units therefrom;
- a reconstruction device which extracts encoded data received without a transmission error and a fault from the discriminated and separated encoded data, and reconstructs and outputs encoded data from the extracted encoded data;
- and
- a second computer that controls at least one of the plurality of receivers, the device and the reconstruction device.
A contents distributing method, comprising the steps of:
- an output step of outputting encoded data;
- and
- a transmission step of transmitting the encoded data outputted in the output step by a plurality of transmitters, wherein
- data encoded by hierarchical encoding is outputted as the encoded data in the output step, wherein the encoding is performed by a computer, and
- at least a part of data of at least one layer among the data encoded by the hierarchical encoding is transmitted by each of the plurality of transmitters in the transmission step.
A contents receiving method, comprising the steps of:
- a receiving step of receiving encoded data transmitted by a plurality of transmitters;
- a step of discriminating and separating individual encoded data units therefrom wherein the discriminating and separating is performed by a computer;
- and
- a reconstruction step of extracting encoded data received without a transmission error and a fault from the discriminated and separated encoded data, and reconstructing and outputting encoded data from the extracted encoded data.
A contents transmitting/receiving method, comprising the steps of:
