BROADCAST DISPLAYING DEVICE, BROADCAST DISPLAYING METHOD, AND COMPUTER PROGRAM

摘要

An MPEG extending portion (21) extends a video signal inputted from a tuner (2) and stores frame-by-frame video data in a buffer portion (22). A displaying portion (23) displays the video of the program on a display (13) based on the video data read out sequentially from the buffer portion (22). A video processing portion (24) copies onto a memory (17) a region in the frame-by-frame video data read out sequentially from the buffer portion (22) which is indicated by the place about the broadcasting station which broadcasts the program which has been defined during the definition of emergency broadcast. A judging portion checks whether either one of the character patterns defined during the definition of emergency broadcast is included in the video data. When either one of the character patterns is included in the video data, a file recording portion (27) records a portion of the video after a portion of the video wherein the character pattern is included for a predetermined period of time as video data on a hard disc (11). Then, a processing portion (26) displays the message saying that there were emergency broadcast on a display (13) and reads out the video data from the hard disc (11) and reproduces it according to the demand for reproduction from a viewer.
