送信装置、送信方法、受信装置および受信方法
Document Type and Number:
Japanese Patent JP6801662
Kind Code:
B2
Abstract:
Convenience in a decoding process on a receiver side for when a predetermined number of high-quality-format image data is transmitted together with basic-format image data is achieved. A base stream including, as an access unit, encoded image data for each picture of basic-format image data, and a predetermined number of enhanced streams, each including, as an access unit, encoded image data for each picture of high-quality-format image data are generated. Here, a predictive coding process is performed on image data in high-quality format by referring to the image data in basic format or image data in another high-quality format, by which an enhanced stream is generated. Then, information indicating decoding order is added to each access unit of the enhanced streams. A container in a predetermined format that includes the base stream and the predetermined number of enhanced streams is transmitted.
