Method and device for channel selection

Abstract

A method (500) for enabling channel selection for an electronic apparatus such as a television signal receiver is performed via a user input device having a key capable of being rotated and pressed. According to an exemplary embodiment, the method includes enabling selection of a plurality of channel numbers to form a group (505), enabling a first one of the channel numbers to be selected as a initial channel number in response to the selection of the plurality of channel numbers in the group (520), enabling display of the initial channel number, enabling display of a second one of the channel numbers that is larger than the initial channel number if the key is rotated in a first direction (530), enabling display of a third one of the channel numbers that is smaller than the initial channel number if the key is rotated in a second direction (530),; and tuning to one of the initial channel number, the second channel number and the third channel number responsive to depression of the key (530).

Description

technical field [0001] The present invention mainly relates to a channel selection technology of an electronic device such as a television signal receiver and / or a radio receiving device, and in particular, relates to a user input device with rotatable and depressible keys, enabling the user to A method of selecting a channel for an electronic device in a simple and convenient manner. Background technique [0002] Electronic devices, such as television signal receivers, are often controlled by user input devices, such as handheld, wireless remote control devices, and / or other user input devices. Current designs of such user input devices typically include a relatively large number of keys / buttons to accommodate the many functions provided by the device. For example, these designs include dedicated keys / buttons dedicated to controlling certain device functions and numeric keypads to aid in channel selection. [0003] User input device designs of the type described above mak...

Problems solved by technology

Also, channel selection using the numeric keypad is difficult if the individual numeric keys are located relatively close to each other on the keypad, even in a well-lit environment

Another disadvantage of using a numeric keypad for channel selection is that it requires the user to remember and enter the exact channel number they desire, increasing their cognitive workload
