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 television 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 television remote or controls on the television to enter the code that signifies the program to be recorded. When the codes are entered they are transmitted to the television and the decoded in the television and then the codes themselves and the CDTL information, which is the result of decoding the codes, could be displayed “on screen”so that the user can verify that the proper codes have been entered. Then at the appropriate time the television would transmit the proper commands to a VCR and a cable box, if present, to command the recording of the selected program. This control function can be carried out by using an infrared link by placing infrared transmitters on the television cabinet, preferably at the corners. The television circuitry would include the capability of storing or learning the infrared code protocols for the VCR and the cable box. The decoder can be embedded into various other equipments associated with television, such as a video cassette recorder, cable box or satellite receiver. In any system the decoder would only have to be present in one of the equipments, such as the cable box, which would then at the appropriate time distribute the proper commands to the other equipments such as a VCR and a satellite receiver to record the desired program. The infrared transmitter can be placed in a infrared dome on the equipment, mounted behind the front panel, or attached to a mouse coupled via a cable to the equipment.
An apparatus for using compressed codes for recorder preprogramming that comprises: a television receiver; means for entering into said television receiver compressed codes each having at least one digit and each representative of, and compressed in length from, the combination of channel, time-of-d
An apparatus for using compressed codes for recorder preprogramming that comprises: a television receiver; means for entering into said television receiver compressed codes each having at least one digit and each representative of, and compressed in length from, the combination of channel, time-of-day, date and length commands for a programs; said television receiver comprising: means for decoding each compressed code into the combination of channel, date, time-of-day and length commands, means for storing said combination of channel, date, time-of-day and length commands, a clock with an output as a function of time, means for reordering said combinations of channel, time-of-day, date and length commands in said means for storing into temporal order, and means for comparing the date and time-of-day commands of the temporally earliest in time combination in said means for storing to the output of the clock for a predetermined relation; means for recording; means for transmitting record on commands to said means for recording after the predetermined relation is found to exist according to the date and time-of-day commands of said temporally earliest in time combination, wherein said means for transmitting is compounded to said television receiver; means for channel selection; wherein said means for transmitting transmit channel select commands to said means for channel selection after the predetermined relation is found to exist according to the channel command of said temporally earliest in time combination wherein said means for transmitting is coupled to said television receiver; and wherein said means for transmitting transmit record off commands to said means for recording following an elapsed time interval corresponding to the length command of said temporally earliest in time combination.
