ADVERTISEMENT INSERTING SYSTEM AND METHOD WITHOUT USING CUE-TONE SIGNAL

摘要

PURPOSE: An advertisement inserting method capable of inserting an advertisement in a commercial break without a cue tone signal and a system thereof are provided to enable a broadcast platform service provider to insert an advertisement in the commercial break even though the cue tone signal which informs the commercial break is not inserted into a digital broadcast. CONSTITUTION: An image switching unit (121) selectively delivers a digital broadcast signal which is received by a transmission service provider and an advertisement signal which is autonomously organized by a broadcast platform service provider to a broadcast transmitting unit (130). A schedule programming unit (125) generates an inprogram advertisement schedule which includes the organization information about the advertisement signal which is autonomously organized by the broadcast platform service provider instead of an advertisement which is organized by a program provider for commercial breaks based on a digital broadcast signal transmission cue sheet. A switching control unit (123) selectively transmits the digital broadcast signal and the advertisement signal to the broadcast transmitting unit by controlling the image switching unit based on the inprogram advertisement schedule.
