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 coded indication of as few as 1 to 8 digits, which are decoded by a decoder built into either the video cassette recorder or a remote controller to convert the compressed coded indication into channel, date, time and length information. The channel, date, time and length information is communicated to a VCR and used to automatically activate the VCR to record a given television program with the corresponding channel, date, time and length. Alternatively, the channel, date, time and length information is decoded directly in a remote controller and only start record, stop record and channel selection commands are sent to the VCR at the appropriate times. An encoder, which may be implemented on a computer, is used to generate the compressed coded indications. The compressed coded indications associated with each television program can be printed in a television program calendar in advance and used with a VCR or remote controller with the decoding means. Algorithms for decoding the compressed codes can be a function of time to ensure security of the decoding method.
