Remote controlled receiver with provisions for automatically programming a channel skip list
First Claim
1. A remote control system of a communications receiver including channel tuning apparatus, comprising:
- a remote control transmitter including a remote keyboard having at least one scan key;
remote channel number generating means for causing coded signals representing sequential channel numbers to be generated when said scan key of said remote keyboard is activated;
a remote memory including memory locations corresponding to respective channels which are addressable in response to said coded channel number representative signals, each of said memory locations storing a coded indication of whether or not the respective channel is preferred for reception;
remote memory examining means for examining the contents of addressed ones of said memory locations of said remote memory and causing said remote channel number generating means to stop changing said coded channel number representative signals when an addressed one of said memory locations contains a preferred channel indication; and
transmitting means for transmitting in a remote control message the coded channel number representative signals generated by said remote channel number generating means;
a local keyboard mounted on said communications receiver including at least one scan key of the same type as said scan key of said remote keyboard;
a remote control receiver included within said communication receiver including receiving means for receiving a transmitted remote control message;
local channel number generating means for causing coded signals representing sequential channel numbers to be generated when said scan key of said local keyboard is activated;
a local memory including memory locations corresponding to respective channels which are addressable in response to said coded channel number representative signals generated by said local channel number generating means, each of said memory locations of said local memory storing a coded indication of whether or not the respective channel is preferred for reception;
local memory examining means for examining the contents of addressed ones of said memory locations of said local memory and causing said local channel number generating means to stop changing said coded channel number representative signals when an addressed one of said memory locations contains a preferred channel indication; and
programming means responsive to said remote control message for automatically programming said local memory with the same preferred and nonpreferred channel information as is contained in said remote memory; and
tuning means included within said communications receiver and responsive to the coded channel number representative signals generated by said local channel number generating means to tune the corresponding channel.

Abstract
A remote control system for a television receiver includes a remote control transmitter with keys for initiating a scan type channel selection operation and a memory for storing a list of preferred channels and non-preferred channels. During a scanning operation the non-preferred channels are passed over (i.e., "skipped"). The battery of the remote control transmitter advantageously also maintains the contents of the "skip" memory so that it may be volatile. So that the same type of channel selection is available locally at the television receiver itself scan keys and an associated skip memory are also incorporated with the chassis of the television receiver. Apparatus is provided to automatically program the local skip memory with the contents of the remote skip memory so that a user does not have to program both skip memories.
