摘要

The present invention is designed to easily avoid the occurrence of display mute at the time of service switching. An image coding unit codes image data of each picture constituting moving image data to generate a video stream. A transmission unit transmits a container in a predetermined format continuously including a first video stream and a second video stream that have been generated in the image coding unit. The first video stream and the second video stream are each composed of first to Mth (M≤N) streams among the first to Nth streams. The transmission unit gives a fixed identifier to each of the first to Nth streams.
