Abstract
A frame generation method includes: demodulating a digital broadcast signal that is based on a received digital broadcast wave; generating a packet including content information obtained in the demodulating; and generating a transmission frame including appended information and the packet. The appended information includes received information that is obtained in the demodulating. The received information is information other than the content information.
Claims10
A frame generation method comprising:
- demodulating a first digital broadcast signal that is based on a received digital broadcast wave;
- generating a first packet including content information obtained in the demodulating of the first digital broadcast signal;
- and
- generating a first transmission frame including appended information and the first packet, the appended information including first received information obtained in the demodulating of the first digital broadcast signal, the first received information being information other than the content information,
- wherein the first received information includes at least interference signal detection information.
