“Signal Transmission Method Signal Transmission Device And Signal Reception Device”

Abstract: A process of a 3D compatible terminal to which content is distributed is made convenient. Meta information and a control signal are transmitted together with content transmitted from a content server 10 in a predetermined transmission mode. The meta information includes information indicating whether the entirety of the content is 3D or a part thereof is 3D, information indicating whether this starts with 2D or 3D when a part thereof is 3D, and identification information of a 3D transmission method when the content is 3D. The control signal includes a signal for identifying 2D and 3D, that is, switching information.regarding switching timing between 2D and 3D. An encoding unit 154 encodes the content stored in a content storage unit 151, the meta information generated by a meta information generating unit 152, and the control signal generated by a control signal generating unit 153 in a predetermined encoding system. The meta information is inserted into a meta file or an MP4 container, for example, to be transmitted.
