Transmission device and transmission method thereof, and reception device

摘要

The present invention relates to a transmission device that enables transmission and reception of connected transmission channels in a 13-segment format and a transmission method of the transmission device, and to a reception device.;The transmission device transmits connected transmission information indicating that connected transmission of a plurality of transmission channels is being performed, the connected transmission information including a field that specifies the modulation method type of each of three or more layers of layered transmission that can be performed on at least one of the transmission channels in the three or more layers.;The reception device receives the connected transmission information transmitted by the transmission device. The present invention can be applied to transmission devices that transmit terrestrial digital broadcast signals, for example.

1. A transmission device for transmitting connected transmission information indicating that connected transmission of a plurality of transmission channels
which have transmission data in a combination of plurality of segment formats which are different from each other is being performed, the connected transmission information including a field for specifying a modulation method type of each of three or more layers of layered transmission that can be performed on at least one of the plurality of transmission channels in the three or more layers, wherein a value indicating that transmission is not to be performed in a second or later layer other than a first layer of the three or more layers is stored in the field for specifying the modulation method type of the layer in which transmission is not to be performed.
