Abstract
A remote control device includes a housing having one or more buttons, a processor unit received in the housing, and a memory coupled to the processor unit. The groups of required or selected channels may be selectively entered into the memory with keys or buttons, and the entered or selected groups of channels may then be easily and quickly controlled and selected by the button. For example, the movie channels and/or the news channels, and/or the sports channels may be stored in the memory and may be easily and quickly selected with the selected buttons.
