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.

Fault tolerant VCR recording control

A known system derives information from the VPS- and Teletext signals and displays the title of the current program and the network name on screen for a few seconds, each time a new channel is selected. The VPS- and Teletext signals contain more program-related information than mentioned above. The present invention concerns deriving the end-time and/or the remaining duration of the current program as well as the starting-time of the next program for display on-screen.

Apparatus for providing TV program information

A driver stage of a horizontal deflection output transistor includes a transformer having a first winding coupled to an input signal at a horizontal deflection frequency, a second winding coupled across a base-emitter junction of the output transistor and a third winding coupled to the emitter of and in series with the output transistor. The third winding couples the emitter current to the base of the output transistor for supplying a substantial portion of the base current during the second half of trace.
