Abstract
The present invention enables a receiving side to easily recognize a high-quality format corresponding to encoded image data included in an extended video stream. Two video streams including a basic video stream including encoded image data of basic format image data, and an extended video stream including encoded image data of high-quality format image data of one type selected from a plurality of types are generated. A container of a predetermined format including the basic video stream and the extended video stream is transmitted. Information indicating a high-quality format corresponding to the encoded image data included in the extended video stream is inserted into the extended video stream and/or the container.
Claims14
A transmitting device comprising:
- an image encoding unit configured to generate two video streams including a basic video stream including encoded image data of basic format image data, and an extended video stream including encoded image data of high-quality format image data of one type selected from among a plurality of types;
- a transmitting unit configured to transmit a container of a predetermined format including the basic video stream and the extended video stream;
- and
- an information insertion unit configured to insert information indicating a high-quality format corresponding to the encoded image data included in the extended video stream into the extended video stream and/or the container.
A transmitting method comprising:
- an image encoding step of generating two video streams including a basic video stream including encoded image data of basic format image data, and an extended video stream including encoded image data of high-quality format image data of one type selected from among a plurality of types;
- a transmitting step of transmitting, by a transmitting unit, a container of a predetermined format including the basic video stream and the extended video stream;
- and
- an information inserting step of inserting information indicating a high-quality format corresponding to the encoded image data included in the extended video stream into the extended video stream and/or the container.
A receiving device comprising:
- a receiving unit configured to receive a container of a predetermined format including two video streams including a basic video stream including encoded image data of basic format image data, and an extended video stream including encoded image data of high-quality format image data of one type selected from among a plurality of types,
- information indicating a high-quality format corresponding to the encoded image data included in the extended video stream being inserted into the extended video stream and/or the container, and
- the receiving device further comprising:
- an information extraction unit configured to extract the information from the extended video stream and/or the container;
- and
- a processing unit configured to obtain image data corresponding to a display capability from the basic video stream and the extended video stream, as display image data, on the basis of the extracted information and display capability information.
A receiving method comprising:
- a receiving step of receiving, by a receiving unit, a container of a predetermined format including two video streams including a basic video stream including encoded image data of basic format image data, and an extended video stream including encoded image data of high-quality format image data of one type selected from among a plurality of types,
- information indicating a high-quality format corresponding to the encoded image data included in the extended video stream being inserted into the extended video stream and/or the container, and
- the receiving method further comprising:
- an information extraction step of extracting the information from the extended video stream and/or the container;
- and
- a processing step of obtaining image data corresponding to a display capability from the basic video stream and the extended video stream, as display image data, on the basis of the extracted information and display capability information.
