Transmission device, transmission method, receiving device, and receiving method for rendering a multi-image-arrangement distribution service

A receiving device, comprising:

• circuitry configured to:
• receive a container including a plurality of video streams, each one of the video streams including encoded image data of a plurality of images and a corresponding piece of position information that includes group picture identification information and location identification information,
• the group picture identification information identifying a group picture that is formed according to the video streams, and
• the location identification information indicating an arrangement position in the group picture for arranging the respective images from the video streams into the group picture;
• extract the video streams and the pieces of control information included in the container;
• decode the encoded data of each of the video streams to obtain a respective piece of decoded image data of the each of the video streams;
• and
• arrange the pieces of decoded image data of the video streams into the group picture according to the piece of the position information of each of the video streams.
