BROADCASTING SIGNAL TRANSMISSION EQUIPMENT, BROADCASTING SIGNAL TRANSMISSION METHOD, PROGRAM, AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide broadcasting signal transmission equipment making data other than television broadcasting data, receivably data with a television receiver for receiving general digital broadcasting.

SOLUTION: The broadcasting signal transmission equipment acquires data from a network or a recording medium, while it receives a digital broadcasting signal. The equipment is equipped with: a conversion means; a detection means; a modulation means; a mixing means; and a transmission means. The conversion means converts the acquired data into a transport stream signal. The detection means detects a broadcasting band other than broadcasting bands where broadcasting is performed in the digital broadcasting signal. The modulation means modulates the transport stream signal into the detected band to generate a modulated signal, based on a modulation scheme of the digital broadcast signal. The mixing means mixes the digital broadcast signal with the modulated signal to generate a mixed signal. The transmission means transmits the mixed signal to the outside.
