Transmission device, transmission method, reception device, reception method, program, and communication system

摘要

The present technique relates to a transmission device, a transmission method, a reception device, a reception method, a program, and a communication system which can realize a system capable of promptly addressing a newly-generated disturbance wave. A broadcasting device of the present disclosure includes: a reception unit which receives reception interference information notified from the reception device; a setting unit which sets a frequency of a notch to be provided in a transmission signal on the basis of the reception interference information that has been received; a modulation unit which provides the notch in accordance with the set frequency of the notch while at the same time generates a modulated signal by modulating information to be transmitted; and a send-out unit which sends out the modulated signal as the transmission signal. For example, the present disclosure can be applied to a broadcasting system which transmits a broadcasting signal conforming to DVB-C2 via a CATV network or a CATV Internet system (DOCSIS), a physical layer of which conforms to the DVB-C2 standard.

主权项

1. A transmission device comprising:
a reception unit configured to receive reception interference information from a reception device; an interference wave analysis unit which receives the reception interference information from the reception unit and analyzes a scale of disturbance to the reception interference information; a setting unit which receives a frequency of an interference wave from the interference wave analysis unit and sets a frequency of a notch to be provided in a transmission signal as the frequency of the interference wave; a modulation unit which receives the frequency of the notch in the transmission signal from the setting unit, provides the notch and simultaneously generates a modulated signal by modulating information to be transmitted; and a send-out unit which receives the modulated signal from the modulation unit and sends out the modulated signal as the transmission signal.
