ABSTRACT:
A Videocassette Recorder including VPS (Video Program System) and VPT (VCR Programmed by Teletext) automatic programming capability continuously compares preprogrammed VPS data to incoming VPS time codes for the currently running program, and to VPS program schedule information. In this way, the VPS and VPT controller in the VCR can detect errors in the original schedule pages from which it was programmed, and correct for those errors in its own record programming memory. Moreover, circuitry according to the subject invention can detect an error in the VPS code of a currently-running television show, correct for the error, and properly record the show.
