Apparatus and method using compressed codes for scheduling broadcast information recording
First Claim
1. An apparatus for using compressed codes for information broadcast recording that comprises:
- an interface that receives compressed codes each having at least one digit and each representative of, and compressed in length from, a combination including a set of channel, time-of-day and length commands for an information broadcast;
a decoder that decodes a compressed code having at least one digit into a set of channel, time-of-day and length commands; and
a controller configured to have a recorder start recording according to the time-of-day command during the twenty-four hour period following receipt of the compressed code by the interface.

Abstract
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.
