Abstract
Synchronous acquisition of a plurality of pieces of image data on the reception side is provided. Each of the plurality of pieces of image data is encoded by an encoder to obtain a plurality of streams. A container of a predetermined format containing the plurality of streams is transmitted. A plurality of encoders performs encoding so as to achieve matching in display timings of corresponding pictures of the plurality of pieces of image data. Alternatively, the plurality of encoders inserts information for associating pictures with each other into each of encoded image data of corresponding pictures of the plurality of pieces of image data.
Claims18
A transmission apparatus comprising:
