Benefits of technology

[0006]To solve the above problems, it is an objective of the present invention to provide a channel memory device for determining whether a signal is present in a tuned channel when a channel is tuned, and for automatically memorizing the channel number if a signal is present in the tuned channel.

Problems solved by technology

However, in the former method, if the channel memory button is not pressed after pressing the digit button for the tuned channel, the desired channel cannot be memorized.
In the latter method, a specific menu must be set, which is inconvenient in practical use.

Embodiment Construction

[0013]As shown in FIG. 2, an automatic channel memory device according to the present invention includes a key input 200, a tuner 202, a signal processor 204, a memory 206, a character signal generator 208, a mixer 210, a display 212 and a controller 214.

[0014]FIG. 3 shows a key input and a main body of a broadcasting signal receiver, in which reference numeral 30 denotes the main body, and reference numeral 32 denotes a remote controller. In particular, a light receiving element 301 for receiving light incident from the remote controller 32 is provided in a specific portion of the main body 30.

[0015]The key input 200 includes a typical remote controller, having digit buttons, as shown in FIG. 3. Unlike the remote controller shown in FIG. 1, in the present invention, a memory button is not provided in the remote controller.

[0016]The tuner 202 tunes to a channel selected among broadcasting signals received through an antenna, in response to the control of the controller 214.

Abstract

In a broadcasting signal processor, an automatic channel memory device for determining whether a broadcasting signal is present in a channel tuned according to user's selection, and for automatically memorizing the tuned channel if a broadcasting signal is present in the tuned channel, is provided. A user's selected broadcasting channel can be accurately stored in a memory without using a separate memory button, thereby simplifying key operation.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a broadcasting signal processor, and more particularly, to an automatic channel memory device for determining whether a broadcasting signal is present in a channel tuned according to user's selection, and for automatically memorizing the tuned channel if a broadcasting signal is present in the tuned channel.[0003]2. Description of the Related Art[0004]In a conventional channel memory method, in order to memorize a tuned channel, first, a user selects a desired channel using a digit button on a remote controller and then presses a channel memory button (10 of FIG. 1) to memorize the tuned channel. In a second conventional channel memory method a menu setting key for setting a menu screen (12 of FIG. 1) is pressed to scan all channels and then channels having a broadcasting signal are automatically memorized.[0005]However, in the former method, if the channel memory button is not pressed a...
