Encoded video recorder/player timer prepro- gramming information listed in a television calendar allows a timer preprogramming feature on a video cassette recorder VCR to be preprogramming using a compressed code of as few as 1 to 8 digits, which are decoded by a decoder built into a video recorder to convert the compressed code into channel, date, time and length information. The channel, date, time and length information is used to select channels, start recording, and stop recording at the appropriate time. A remote control transmitter mounted in the video recorder transmits signals to an external channel selection device to select channels for recording. A local channel map is stored so that the channel information from the compressed codes can be utilized to tune the correct channel even though channel numbers in different localities may be different. A remote for controlling the video recorder is included and may be a universal remote control capable of storing infrared code protocols for commanding different brands and model of video devices. The programming of infrared codes and protocols in the remote control is performed by transmissions over telephone lines. The programming of local channel map data and infrared codes and protocols in the video recorder are performed by transmissions over telephone lines to the remote control followed by transmissions from the remote control to the video recorder.
