Abstract
There is provided a transmission device including: a transmission unit that transmits a container in a predetermined format including a first component stream that has, as component data, transmission video data obtained by switching between a plurality of types of transmission video data, and a predetermined number of second component streams that have pieces of other component data; and an information insertion unit that inserts dynamic range information of the component data that each of the component streams has into the component streams.
Claims10
A transmission device comprising:
- circuitry configured to:
- generate a video component stream that has video component data, the video component data being obtained by switching between a plurality of types of video data;
- generate a non-video component stream that includes non-video component data;
- insert first control information specifying a first dynamic range of the video component data into the video component stream;
- insert second control information specifying a second dynamic range of the non-video component data into the non-video component stream;
- and
- generate a container in a predetermined format that includes the video component stream with the first control information inserted therein, and the non-video component stream with the second control information inserted therein;
- and
- transmit the container.
