BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a storage channel display device in which C / TV and VCT equipped with a channel storage device can identify a channel corresponding to a broadcasting station by displaying all stored channels and broadcast station names on a CRT at a time.

In the conventional C / TV and VCR, the radio wave received through the tuner was tuned by operating the microcomputer by operating the remote controller transmitter and the controller configured in the C / TV or VCR itself in order to receive the radio wave transmitted from each broadcasting station.

At this time, the user can arbitrarily set the channel for tuning the radio wave received through the tuner using the remote controller and the controller and store it in the microcomputer, and then operate the remote controller or controller to receive the radio wave received through the tuner. When the channel is selected, the microcomputer recognizes the operation of the remote control transmitter or the controller and tunes and receives only the tuned channel among the radio waves received through the tuner.

If the OSD function is used, the microcomputer that recognizes the channel tuned by the remote control transmitter or the controller tunes the radio wave through the tuner, and outputs the channel OSD data according to the tune by the OSD circuit. Shown in the phase.

However, the channel memorized by key input of the remote control transmitter or controller was selected by using the remote control transmitter or controller, and the selected channel was tuned and the OSD circuit was operated to display on the CRT.

Therefore, when a user selects a channel several times, it is troublesome to find a channel memorized according to a stored station while sequentially selecting all available channel numbers.

In particular, as a channel is selected, only one channel is displayed on the CRT, and thus, it is cumbersome to repeatedly operate a remote control transmitter or a controller in order to select a channel of a desired broadcasting station.

Therefore, the object of the present invention

The present invention provides a circuit for identifying a channel according to a broadcasting station by temporarily displaying all channels and broadcasting station names arbitrarily set by a user on a CRT by operations of a remote control transmitter and a controller.

That is, a channel display (in the present invention, a key for displaying all channels and broadcast stations stored on the CRT is described as a channel display key) on a remote control transmitter or controller, and the channel stored in the operation of the channel display key The station name can be displayed on the CRT.

The present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of the present invention.

Remote control transmitter 10 for transmitting a wireless data signal to control the microcomputer 30 to control various functions of the C / TV and VCR, and wired to the C / TV and VCR to control the operation of the microcomputer 30 With controller 20 to do,

A microcomputer 30 for tuning the received radio wave by operating the tuner 40 at the output of the remote controller transmitter 10 and the controller 20 and outputting various OSD data to the OSD circuit 50;

It consists of an OSD circuit 50 for operating OSD data of the microcomputer 30 to output the OSD characters on the CRT.

That is, in the circuit for storing the channel and the broadcast station name of the radio wave received through the tuner 40 by the key input of the remote control transmitter 10 and the controller 20 in the microcomputer 30,

And forming a channel display key for displaying all channels and broadcast station names stored in the remote control transmitter 10 and the controller 20.

The microcomputer 30 outputs OSD data of all channels and station names stored in the microcomputer 30 to the OSD circuit 50 by inputting the channel display keys of the remote controller transmitter 10 and the controller 20.

The OSD circuit 50 to which the OSD data is applied operates to display OSD data on the CRT for a predetermined time by operating with the OSD data.

Hereinafter will be described the operation and effect of the present invention.

In the C / TV and the VCR having the channel memory device, the microcomputer 30 operates by key input of the remote controller transmitter 10 and the controller 20 to tune the radio wave received through the tuner 40 so that the tuner 10 operates. It tunes the radio wave received through.

At this time, the user operates the kernels formed in the remote controller 10 and the controller 20 to store the name of the broadcasting station and the corresponding channel of the received radio wave in order to tune the radio wave received by the tuner 40 to be stored in the microcomputer 30.

The channel and broadcasting station names stored in the microcomputer 30 are displayed on the CRT through the OSD circuit 50, so that the user can confirm which broadcasting station name is stored in which channel.

In this way, the channel and the station name are stored in the microcomputer 30 by the key input of the remote control transmitter 10 and the controller 20, and the channel of the broadcast station that the user wants to watch is the key input of the remote control transmitter 10 and the controller 20. If selected, the selected channel of the radio waves received by the tuner 40 is tuned to the microcomputer 30.

In addition, the microcomputer 30 outputs the selected channel and broadcast station name OSD data of the corresponding channel to the OSD circuit 50 to operate the OSD circuit 50 to display the selected channel and broadcast station name on the CRT.

In this case, when a user who does not know which station is to be tuned by inputting the numeric keys of the remote control transmitter 10 and the controller 20 wants to tune into the broadcasting station by inputting the numeric keys of the remote control transmitter 10 and the controller 20, The sequential input of the numeric keys formed on the remote control transmitter 10 and the controller 20 should find a broadcasting station to be tuned.

In addition, the microcomputer 30 sequentially outputs OSD data of channel and broadcast station names according to the numeric key input to the OSD circuit 50 so that the selected channel and broadcast station name are displayed on the CRT.

In this way, the user must sequentially input the numeric keys formed on the remote controller 10 and the controller 20 to form a channel display key on the remote controller 10 and the controller 20 to eliminate the inconvenience. All channel and broadcasting station names stored in the microcomputer 30 are displayed on the CRT.

This will be described in detail with reference to the second flowchart of the present invention.

While watching normal TV using C / TV or VCR, if the user wants to watch another broadcast but does not know the channel number of the broadcast to be watched, input the channel display key formed on the remote controller transmitter 10 or the controller 20. Let's do it.

At this time, the microcomputer 30 recognizes the input of the channel display key of the remote controller transmitter 10 and the controller 20 and outputs OSD data of all channels stored in the microcomputer 30 and the name of the corresponding broadcasting station to the OSD circuit 50. An operation 50 is performed to display all channels and corresponding broadcast station names stored on the CRT.

As such, all channel and station names displayed on the CRT disappear after being displayed on the CRT for a predetermined time unless the user fades out by using the remote controller 10 and the controller 20.

Accordingly, the user can select a channel of a broadcast to be watched by inputting numeric keys of the remote controller 10 and the controller 20.

As described above, the present invention

All channels and station names memorized by the channel display key inputs of the remote control transmitter and the controller are displayed on the CRT at a time so that the channels according to the stations can be easily identified.
