DIGITAL TELEVISION BROADCASTING WAVE TRANSMISSION APPARATUS AND BROADCASTING WAVE TRANSMISSION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a digital TV broadcasting wave transmission apparatus which transmits highly definite still image information to be required in emergency, while requiring neither a broadcasting device to transmit a still image in emergency, nor a receiver side circuit corresponding to the device, and also to provide a broadcasting wave transmission method.;SOLUTION: A video input control part 102 selects an arbitrary input video (still image data) converted into a digital video signal by a video signal input part 101. The input video is stored in a video data memory 103 and encoded by compression in a video signal processing part 104. The compression video signal of each frame included in a head VOB is stored in a head VOB memory 106, repetitively read by a video stream control part 105 until the input video signal (the still image) is changed-over, and multiplexed with a compression sound signal, etc., in a signal multiplexing part 112. Then, the signal is transmitted as broadcasting waves from a modulation signal transmitting part 113 via an antenna 114.;COPYRIGHT: (C)2008,JPO&INPIT
