METHOD AND APPARATUS FOR PROVIDING EMERGENCY ALERT BROADCASTING
摘要
PURPOSE: A disaster broadcasting providing method and apparatus are provided to offer disaster broadcasting to each channel through one source service encoder with the insertion of an abnormally RS encoded result. CONSTITUTION: An Ensemble MUX(Multiplexer)(240) multiplexes the disaster message of the disaster message generator(100a) in the ETI(Ensemble Transport Interface) frame of an ETI frame generator(230). According to the bit rate of a transfer rate controller(110), video stream bit rate controllers(140a~140c) switch the normally RS(Reed-Solomon) encoded stream of RS encoders(130a~130c) and the null stream of the generators(150a~150c) of an abnormally RS encoded null stream through video stream switches(141a~141c).
