Abstract

A complex television system is provided for accommodating at the same time both highly technically oriented and less technically oriented users of the system. The system includes a state of the art complex television, a complex remote control transmitter device for use by the technically oriented user in both programming and, if desired, controlling the television, and a simple auxiliary remote control transmitter device for the less technically oriented user. The simple auxiliary remote control transmitter device has a minimum of keys, such as power-on, channel-up, channel-down, volume-up, and volume-down, as well as a switch which identifies the user. Different power-on and channel-up and down codes for each switch position is provided by the simple auxiliary remote control transmitter device, and each such code is different than the corresponding codes of the complex remote control transmitter device. In this manner, a microprocessor in the television will recognize which user is in control. By using the complex remote control transmitter device, values for personal preference parameter and/or channel rings associated with each user may be entered and stored in a programmable memory of the television. Then, when the television recognizes the power-on code for a particular user, the personal preference parameter and/or channel rings are immediately accessed. In this manner, less technically oriented users may be the beneficiaries of complex personal preference rings programmed by them by a highly technically oriented user, and will only have to deal with a simple auxiliary remote control transmitter device to control the television.
