Abstract
A new service can be provided as maintaining the compatibility with a related audio receiver, without deteriorating an efficient usage of a transmission band. A predetermined number of audio streams having first encoded data and second encoded data which is related to the first encoded data are generated, and a container in a predetermined format including these audio streams is transmitted. The predetermined number of audio streams are generated so that the second encoded data is discarded in a receiver which is not compatible with the second encoded data.
Claims19
A transmission device comprising:
- an encoding unit configured to generate a predetermined number of audio streams including first encoded data and second encoded data which is related to the first encoded data;
- and
- a transmission unit configured to transmit a container in a predetermined format including the generated predetermined number of audio streams,
- wherein the encoding unit generates the predetermined number of audio streams so that the second encoded data is discarded in a receiver which is not compatible with the second encoded data.
A transmission method comprising:
- an encoding step of generating a predetermined number of audio streams including first encoded data and second encoded data which is related to the first encoded data;
- and
- a transmission step of transmitting, by a transmission unit, a container in a predetermined format including the generated predetermined number of audio streams,
- wherein, in the encoding step, the predetermined number of audio streams are generated so that the second encoded data is discarded in a receiver which is not compatible with the second encoded data.
A reception device comprising
- a reception unit configured to receive a container in a predetermined format including a predetermined number of audio streams having first encoded data and second encoded data which is related to the first encoded data,
- wherein the predetermined number of audio streams are generated so that the second encoded data is discarded in a receiver which is not compatible with the second encoded data,
- the reception device further comprising a processing unit configured to extract the first encoded data and the second encoded data from the predetermined number of audio streams included in the container and process the extracted data.
A reception method comprising
- a reception step of receiving, by a reception unit, a container in a predetermined format including a predetermined number of audio streams having first encoded data and second encoded data which is related to the first encoded data,
- wherein the predetermined number of audio streams are generated so that the second encoded data is discarded in a receiver which is not compatible with the second encoded data,
- the reception method further comprising a processing step of extracting the first encoded data and the second encoded data from the predetermined number of audio streams included in the container and processing the extracted data.
