  • Patent number: 6430359
    Abstract: Encoded video recorder/player timer preprogramming information listed in a television calendar allows a timer preprogramming feature on a video cassette recorder VCR to be programmed using a compressed code of as few as 1 to 8 digits, which are decoded by a decoder built into a remote control, video cassette recorder, television or other video device to convert the compressed code into channel, date, time and length information. The compressed code indications associated with each television program can be printed in a television program calendar in advance. The user would use the remote control or controls on the video device to enter the code that signifies the program to be recorded. The channel, date, time and length information is used to select channels, start recording, and stop recording at the appropriate time.
