As the user selects the simple reservation function, the corresponding program sequence stored in the storage medium is detected and displayed on the monitor (see FIG. 1). . Therefore, when the user checks the displayed program order and selects the broadcast contents to be reserved, the reserved recording function is automatically performed at the time when the broadcast contents are started.

On the other hand, each channel for receiving a broadcast signal transmitted from a broadcasting station is set differently for each region divided by a predetermined unit, and when the user moves the television from one region to another, the channel must be reset manually. . Therefore, there is a problem that the user feels uncomfortable.

In addition, as the channels allocated to each broadcasting station for the region are different from each other, the user must remember the channel number corresponding to the broadcasting station of the region, and the user must remember the channel number corresponding to the broadcasting station for each region. Since it is almost impossible, there is a problem in that the user has to search all channels in order to tune in the broadcasting contents transmitted from the corresponding broadcasting station, and there is a problem in that time loss occurs.

Accordingly, the present invention is to solve the above-mentioned problems, the purpose of the present invention, if the user selects the broadcast station name, the channel corresponding to the broadcast station name regardless of the region by analyzing the packet data by the Korean reservation recording system It is to provide a channel automatic tuning method using the Korean reservation recording system that is automatically selected.

A feature of the present invention for achieving the above object is a manipulator equipped with a plurality of direct tuning keys assigned to respective broadcasting stations to directly select a broadcasting station, a tuner for receiving a broadcast signal, and a tuner received by the tuner. A channel automatic tuning method using a Korean reservation recording system of a broadcast signal processing apparatus having a memory for detecting and storing packet data included in a broadcast signal, and a microcomputer for controlling each component according to a broadcast station name input from the manipulator. Detecting the packet data among the received broadcast signals, storing the station name included in the packet data and the channel of the corresponding region corresponding to the station name in the memory, and detecting the station name corresponding to the direct channel selection key input from the manipulator. And compares the detected broadcasting station name with the broadcasting station name stored in the memory. A channel auto-tuning method using a Korean-type reservation recording system which performs a process of tuning a corresponding channel controlling the tuner after detecting a channel corresponding to a broadcasting station name.

In the above aspect of the present invention, a first step of receiving the packet data of the broadcast signal to store the broadcast station name and channel data of the region in the memory; A second step of detecting the same broadcast station name by comparing the broadcast station name corresponding to the input direct tuning key with the broadcast station name stored in the memory; Detecting a channel corresponding to the detected broadcast station name; And controlling the tuner to perform a fourth process of tuning the corresponding channel.

Further, as a result of comparing the broadcasting station name corresponding to the direct channel selection key input through the second process with the broadcasting station name stored in the memory, if the same broadcasting station name does not exist, the process of outputting a predetermined alarm signal indicating that an error has occurred is further performed. It is desirable to.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of a channel automatic tuning method using the Korean reservation recording system according to the present invention will be described in detail.

2 is a schematic block diagram for performing the channel automatic tuning method using the Korean reservation recording system according to the present invention.

Referring to FIG. 2, a tuner 2 for tuning packet data by the Korean reservation recording system among broadcast signals received from the antenna 1, and mounted at a predetermined position of a television so that a user can directly select various functions of the television. Key control section 3, memory 4 for storing packet data, monitor 5 for displaying broadcast signals tuned by tuner 2, and operation signals and remotes applied from key control section 3; It consists of a microcomputer 6 which controls each of the above-described components in accordance with a remote control signal applied from a controller (not shown).

On the other hand, the remote controller and the key control section 3, as shown in (a) and (b) of FIG. 3, a plurality of direct tuning keys assigned to each broadcasting station name so that each broadcasting station can be selected by one key operation. (7) is provided.

The operation of the present invention having the configuration as described above will be described with reference to FIG.

The microcomputer 6 checks whether the main switch is turned on by applying a predetermined control signal from the key operating section 3 or the remote controller (refer to (a) and (b) in FIG. 3) (S1). If it is determined in this step S1 that the main switch is not turned on, the microcomputer 6 returns to the above-described step S1 to continuously check whether the main switch is turned on.

If it is determined in step S1 that the main switch is turned on, the microcomputer 6 receives the packet data among the broadcast signals received by the tuner 2 and receives the broadcast station name and channel included in the packet data. It stores in the memory 4 (S2).

Thereafter, the microcomputer 6 checks whether the direct tuning key 7 mounted on the remote controller or the key control section 3 (refer to (a) and (b) in FIG. 3) has been selected to directly tune into the broadcasting station.
