Abstract:
The present invention enables a given partial image within a wide view angle image to be consistently displayed between receivers. According to the present invention, a container having a prescribed format and including a video stream acquired by encoding moving image data of a wide view angle image is transmitted. Information about a target point set within the wide view angle image is inserted into the video stream. For example, information about the target point includes information about the angle from a horizontal axis and the relative radius of an ellipse with respect to a reference point set on an effective image region of an ellipse present within the rectangular region of the wide view angle image. Furthermore, for example, information about the target point includes information about a two-dimensional relative positon from a point which becomes a reference within the rectangular region, when the rectangular region of the wide view angle image is set as the effective image region.
