TRANSMISSION DEVICE, TRANSMISSION METHOD, RECEPTION DEVICE, AND RECEPTION METHOD

Abstract:

The present technology relates to a transmission device, a transmission method, a reception device, and a reception method that make it possible to improve transmission efficiency. Provided is a transmission device including a first time interleaver that performs first time interleaving conforming to a first system, on an error correction code block to be included as a data frame in a physical layer frame, in which the error correction code block conforms to a second system, and when performing the first time interleaving, the first time interleaver applies a pointer indicating an offset of a start position of the error correction code block included at a start of the data frame. The present technology can be applied to, for example, a transmission system compatible with a broadcast system such as an ISDB-T system.
