Embodiment Construction

[0036] The present invention describes a system for automatically selecting an IR code set suitable for remotely controlling a particular video device, such as a junction box, from a plurality of IR code sets stored, for example, in a VCR. The system sends a series of commands to the specific video device using a selected test IR code set, and monitors the results of these commands by examining the video signal from the video device. The results are analyzed to determine if the test IR code set successfully controlled the video device. If the test IR code set does not successfully control the video device, the system will cycle through all stored IR code sets as test IR code sets until an IR code set that successfully controls the video device is found.

[0037] Figure 1 depicts an embodiment of the present invention in which a tuner 10 receives a television signal from an external source and outputs a video signal derived from the television signal on the channel on which the...

Abstract

A television tuner (10) controller has a memory (22) with a number of sets of remote control codes for use in controlling a television tuner (10), such as a cable box. The television tuner changes the channel it is tuning to a specific channel when it receives a set channel remote control command identifying the specific channel. The tuner (10) controller can detect the channel tuned by the television tuner (10) whenever the predetermined base channel is tuned by the television receiver (14).

Description

technical field [0001] The invention relates to a system and method for automatically selecting a code set of a remote controller, in particular to an automatic programming of a controller, which enables the controller to remotely control another device through an infrared signal. Background technique [0002] As televisions, video cassette recorders, and other household devices have become more common, the number of devices that can be remotely controlled has increased. Most of these devices use an infrared signal transmitter (combined with a receiver connected to the device itself) as a "remote control". Typically, the manufacturer of the device has integrated such a remote control with the device. Of course, the remote control is already capable of controlling its associated devices. However, because different manufacturers use different sets of infrared codes, one manufacturer's remote typically cannot control another manufacturer's device. As the number of remote-con...
