FIELD: physics.
SUBSTANCE: transmission device comprises: a hierarchical classification section for classifying, into multiple layers, image data for each frame included in the moving image data; an image encoding section for encoding the classified image data for each layer and generating a plurality of video streams comprising the encoded image data of each of the plurality of layers; a transmission section for transferring the container of a predetermined format including the generated video stream, and an identification information insertion section configured to insert stream identification information to identify the video stream of each layer in the container layer. The image encoding section is configured to perform encoding such that the referenced frame belongs to the image data layer performing the reference and/or the lower layer as compared to the image data layer performing the reference.
EFFECT: adaptation of the receiving device to play video at an appropriate frame rate.
