Remote control dedicated keybutton for confirming tuner setting of a TV set to a specific channel setting

摘要

Portable remote controller for accessory television devices for program channel selection and other operating functions. A single uniquely identified keybutton enables the viewer to remotely reset a televisor's video input to an unused channel such as channel 3. After a reset, the remote controller's functions revert to whatever device was previously selected. A variation provides that intentional pressing of a a device selection button, such as a CBL cable box select button, for a few seconds implements the input reset mode to automatically urge a specific video input selection. Another variation senses an extent of a TV or other device's select keybutton action. A partial depression of the TV keybutton may merely initiate the usual device selection function. By further depressing the TV keybutton a preceptive wireless signal is automatically sent to remotely affirm the appropriate video input selection.
