Abstract
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.

Claim 1
Independent Claim
283 words
A videocassette recorder, comprising: means for selecting a particular television signal from a plurality of signals for recording, said particular television signal having an identifying signal encoded therein, said identifying signal being subject to content error; control means coupled to said selecting means for causing said selecting means to select said particular television signal for recording; means for receiving said identifying signal of said particular television signal when said particular television signal is transmitted; means for receiving data related to a schedule of times and dates television programs to be transmitted at a future times, said data related to said schedule of times and dates television programs being subject to content error; means for producing a signal which when displayed produces a display comprising a user readable schedule corresponding to said schedule data; means for selecting individual ones of said television programs to be transmitted at a future time for recording; storage means coupled to said control means for storing said schedule data and for storing data related to said selected individual ones of said television programs to be transmitted at a future time; wherein said control means in response to a reception of said identifying signal of said particular television signal when said particular television signal is transmitted searches said data related to a schedule of times and dates television programs to be transmitted at a future time for said identifying signal of said particular television signal, and upon failure to detect data related to said identifying signal of said particular television signal, automatically changes said identifying signal of said particular television signal to the identifying signal of a particular television program which said schedule indicates as the currently running television program.
Claim 2
Dependent Claim
283 words
A videocassette recorder, comprising: means for selecting a particular television signal from a plurality of signals for recording, said particular television signal having an identifying signal encoded therein, said identifying signal being subject to content error; control means coupled to said selecting means for causing said selecting means to select said particular television signal for recording; means for receiving said identifying signal of said particular television signal when said particular television signal is transmitted; means for receiving data related to a schedule of times and dates television programs to be transmitted at a future times, said data related to said schedule of times and dates television programs being subject to content error; means for producing a signal which when displayed produces a display comprising a user readable schedule corresponding to said schedule data; means for selecting individual ones of said television programs to be transmitted at a future time for recording; storage means coupled to said control means for storing said schedule data and for storing data related to said selected individual ones of said television programs to be transmitted at a future time; wherein said control means in response to a reception of said identifying signal of said particular television signal when said particular television signal is transmitted searches said data related to a schedule of times and dates television programs to be transmitted at a future time for said identifying signal of said particular television signal, and upon failure to detect data related to said identifying signal of said particular television signal, automatically changes said identifying signal of said particular television signal to the identifying signal of a particular television program which said schedule indicates as the currently running television program.
Claim 3
Dependent Claim
22 words
