Description

[0001] The present invention relates to a method of changing a fast channel of a remote controller,

The present invention relates to a fast channel changing method of a remote controller, and more particularly, to a quick channel changing method of a remote controller for transmitting a channel key signal and an acknowledge key signal in conjunction with a microcomputer of a remote controller when a channel key signal is input .

1 shows a television 1 for displaying images of various channels. To change the channel of the video equipment, a remote controller 4 having a channel increase key 2 and a channel decrease key 3 ) Is usually used.

When the channel increase key 2 of the remote controller 4 is pressed once, one channel increases. When the channel decrease key 3 is pressed once, one channel decreases.

If the channel increase key 2 is continuously depressed for a predetermined time, the channel is continuously increased for a certain period of time. If the channel decrease key 3 is continuously depressed for a predetermined time, .

Accordingly, in the conventional channel changing method, when a user presses the channel keys 2, 3 to display images of a plurality of channels one by one on the screen M of the video apparatus, The channel is selected by not depressing the channel keys 2, 3.

However, in the conventional channel changing method, when changing the channel by pressing the channel keys 2 and 3 once, there is a problem that a considerable time is delayed until the channel is actually switched compared to the pressing speed of the channel keys 2 and 3.

This is because the waiting time is required for judging whether the signal inputted from the data processing unit of the remote controller side is a single key signal or a plurality of continuous combined key signals. For example, if there is no additional key signal input for a certain period of time after the initial key operation, it is determined as a single key signal, and if the input of the additional key signal continues within a predetermined time, it is determined as a combined key signal.

Further, in the prior art, a separate confirmation key is formed on the remote controller 4 in order to shorten the waiting time, and when the user presses the confirmation key, the channel is immediately changed without waiting time. However, this method has a problem in that the channel key 2 and the confirmation key must be continuously pressed.
