Title: METHOD OF DETECTING PORTION OVERLAPPING BETWEEN BROADCAST PROGRAMS, AND IMAGE AND VOICE RECORDING DEVICE MOUNTING THEREOF
Abstract:
When n is set to be an integer not less than 2, (n-1)th program data and (n)th program data relating to a serial drama are recorded in a video data recording section (11), and a voice decoding section (12) generates voice data relating to respective programs.  An overlapping portion determining section (13) detects an overlapping portion by respectively extracting partial data to be compared from the end portion of the voice data relating to the (n-1)th program and the leading portion of the voice data relating to the (n)th program, and records the overlapping period of the (n-1)th program and the(n)th program in an overlapping period storing section (14).  A video data compiling section (15) deletes the portion of the overlapping period recorded in the overlapping period storing section (14) from the end of the (n-1)th program data, recording the data in the video data recording section (11) as compiled data relating to the (n-1)th program.
