摘要:
Digital compressed codes, associated with advertisements enable a user to selectively record additional information, which would be broadcast on a television channel at a later time. The advertisement could be print advertisement or broadcast advertisement on television or radio. The user enters the digital code (I code) associated with an advertisement into a unit with a decoding means which automatically converts the code into CTL (channel, time and length). The unit within a twenty four hour period activates a VCR to record information on the television channel at the right time for the proper length of time. The decoded channel, time and length information can be communicated directly to a VCR and used by the VCR directly to automatically activate the VCR to record a given television information broadcast corresponding to the communicated channel, time and length. Alternately, the channel, time and length information can be decoded directly in a remote control unit and only start record, stop record and channel selection commands sent to the VCR at the appropriate times. Algorithms for decoding the I codes can be a function of time to ensure security of the decoding method. A method is included for use of the I codes with cable channels.
