BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable box controller connected between a cable line and a VCR applied from a cable TV station and more particularly to a cable box controller connected between a cable line and a VCR, And automatically storing all received broadcast channels by automatically searching for broadcast channels received by the VCR and the cable box controller, and a method for automatically storing the broadcast channel in a cable box controller will be.

Generally, when a cable TV is received from a cable TV station, a cable box controller is connected to the cable line that is connected from the cable TV station to the viet al.

Currently, only when the reserved recording function is activated, the VCR outputs a signal for converting the channel of the cable box controller to the channel on the reserved program to the cable box controller through the remote controller output terminal of the VCR, thereby changing the input channel of the cable box controller.

If you want to switch the cable TV channel while receiving cable TV, you must switch the cable box controller's input channel to the remote controller that controls the cable box controller. At this time, the VCR must have the VCR input channel set to match the output channel of the cable box controller (eg 3 or 4 channels).

More specifically, when a cable TV broadcast is scheduled to be recorded, the microcomputer initially changes the input channel of the VCR to the output channel of the cable box controller, and at the same time, Outputs the remote control signal for the box controller.

At this time, the remote controller signal output to the cable box controller recognizes the manufacturer of the cable box controller initially set, and outputs data corresponding to the remote controller signal of the manufacturer.

Thus, the cable box controller receives the remote control signal sent from the VCR and switches the input channel of the cable box controller to the broadcast channel that the user wants to reserve.

FIG. 1 is a block diagram schematically showing a connection state of a conventional cable box controller and Vsial. In FIG. 1, an RF signal including a video signal and a voice signal, which is input from a cable TV broadcasting station 1 through a cable 5, Is supplied to the VCR 20 through the box controller 10 and the VCR 20 is connected to the TV 30 in a wired manner so that the video and audio signals to be output are outputted through the screen of the TV 30. [

First, the control function when the conventional cable box controller 10 and the VCR 20 are connected will be described. First, the user plays back the video tape through the VCR 20, , The VCR 20 is stopped and the channel of the cable TV is tuned to the cable box controller 10 by using a dedicated remote controller so as to watch it.

If the broadcast channel of the cable TV received while watching the cable TV broadcast being operated as described above is auto-searched, the data corresponding to the broadcast channel received through the cable box controller is not output to the blogger.

More specifically, when the user first inputs the automatic setting function to the VCR 20, the VCR 20 selects the broadcasting frequency according to the mode input by the user, In memory.

That is, if the user inputs the channel selecting function of the television, the tuner performs the channel selecting function by receiving the broadcasting frequency of the television. If the user inputs the channel selecting function of the cable TV, And when the user selects a channel thereafter, it outputs the set broadcast frequency.

However, when the cable TV 1 and the television 30 are connected by the VCR 20 and the cable box controller 10 is connected between the cable TV 1 and the VCR 20, And then operates the VCR 20 again to tune into the cable TV 1. [0050]

That is, the user tries to select the broadcast frequency received on the TV through the VCR 20, and then operates the VCR again to tune into the cable TV channel, which is troublesome and time consuming .

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems, and it is an object of the present invention to provide a cable box controller, which is connected between a VCR and a cable TV broadcasting station, And a method for automatically storing a broadcast channel of a cable box controller capable of performing an automatic search of a channel.

In order to accomplish the above object, the present invention provides a cable box controller, which is connected between a cable TV station and a Vitis, to convert a broadcast signal of a cable TV and apply the signal to Vitis; And a VCR connected to the cable box controller,

A preamplifier built in the VCR and amplifying a broadcast signal applied to the VCR;

A video circuit unit built in the VCR and connected to the preamplifier unit to distinguish broadcast signals synchronized in a broadcast signal applied thereto;

A microcomputer built in the VCR and applying a fixed channel signal of the VCR to the preamplifier unit, detecting a broadcast signal of a cable TV having a synchronization signal from the video circuit unit, and outputting cable TV channel data;

And a cable box controller connected to the microcomputer of the VCR and having a receiver for receiving cable TV channel data from the microcomputer.

Preferably, the microcomputer further includes a VCR channel fixing step in which the channel of the VCR is fixed to the set channel;

A cable TV channel determination step of determining whether a cable TV channel is equal to or more than a set channel after the VCR channel fixing step;

A channel data output step of outputting cable TV channel data to the cable box controller if the channel is less than a channel set in the cable TV channel determination step;

A synchronization signal determination step of determining whether there is a synchronization signal in a signal applied to the VCR in the cable box controller after the channel data output step;

A memory step of storing broadcast channel data of a cable TV broadcast channel when a sync signal is detected in the sync signal determining step;

The step of determining whether the synchronization signal is present or the memory channel is stored in the memory step, and then incrementing the cable TV broadcasting channel data by one.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a schematic block circuit diagram according to the present invention; FIG. FIG. 3 is a flowchart of a VCR having a cable TV control function according to the present invention.

2, the microcomputer 230 sequentially outputs the cable TV channel data to the cable box controller 100 in a state in which the data corresponding to the fixed channel of the 3 or 4 channels of the VCR is applied to the pre-amplifier unit 210 do.

The cable box controller 100 applies the cable TV channel data applied through the receiver to the video circuit unit 220 through the preamplifier unit 210. The video circuit unit 220 receives the cable TV channel data, The signal is distinguished from the signal with and without the synchronization signal.

At this time, the microcomputer 230 detects and automatically memorizes the broadcast channel having the synchronization signal.

Referring to FIG. 3, the microcomputer fixes a channel of the VCR to a set channel composed of three channels or four channels (S10).

After the fixing step S10, it is determined whether the cable TV channel is equal to or more than the set channel (S20).

If it is less than the channel set in the determining step S20, the cable TV channel data is output to the cable box controller 100 (S30).

After the output step S30, the cable box controller 100 determines whether there is a sync signal in the signal applied to the VCR 200 (S40).

If the sync signal is determined in the sync signal determination step S40, the broadcast channel data of the cable TV broadcast channel is stored in the memory S50.

In step S40, the sync signal is not present or the broadcast channel data is memorized in the memory step S50, and then the cable TV broadcast channel data is incremented by one (S60).

As described above, according to the present invention, a cable box controller connected between a cable TV station and a VCR is provided with a receiver for receiving broadcast channel data generated in a microcomputer of the VCR, and a cable box controller Channel signal is detected by the video circuit section and only the channel signal in which the synchronizing signal exists is stored in the microcomputer. When the user performs the auto search using the VCR, the cable TV broadcasting channel applied to the cable box controller is automatically changed Cable TV broadcasts.
