The present invention relates to direct K screen control of a video recording apparatus, and in particular, when receiving data of various broadcasting stations performing direct K broadcasting and displaying the immediately K screen, data of several broadcasting stations are simultaneously displayed on one screen. Method and apparatus for displaying multiple programs on one screen while displaying a portion that is not represented (in the case of a long broadcast title is cut off at the back of the title) multi-screen control device of K-bar, It relates to a control method.

In general, the instant recording method using the direct K method has been invented to improve the following problems according to the timer reservation recording by the conventional time setting.

The timer reservation recording method by time setting is achieved by recording a broadcast signal of a set channel from a set date and time by a set length using a timer built in a video recorder. Since the time-controlled reservation recording method is controlled only by the set time and the set channel, there is no relation to what the contents of the recorded program are. Therefore, if the program and the set time do not coincide exactly with the preset recording setting, the video recorder will generate a false record.

Therefore, the reservation recording method using the direct K method avoids the conventional reservation recording method for inputting the start time and length of a program, and transmits a unique identification code to the broadcast program, and transmits the identification signal transmitted using an appropriate decoder at the receiving end. Detecting and when the identification signal of the pre-recorded recording program input in advance coincides with the reservation recording program.

In the reservation recording method using the bar K method as described above, in the conventional bar K screen display method, as shown in FIG. 1, broadcasting station data is allocated to each allocation area of the RAM of the video recorder at the receiving end. K data is stored.

If the user inputs the K key while the bar K data is stored in the RAM, the data of the designated area on the first channel of the channel being watched is read and the menu screen as shown in FIG.

The control method for the conventional bar K screen as described above is as follows. For convenience of explanation of the conventional method, K data service is

RAM Address Station Name Channel

00 SBS 06

01 KBS1 09

02 MBC 11

Suppose that only three broadcasting stations transmit (hereafter, the same).

The database RAM separately stores and stores the K data of each broadcasting station. That is, SBS data is stored at address = 00, KBS1 data is stored at address = 01, and MBC data is stored at address = 02.

At this time, if the user directly inputs the K key while watching the SBS broadcast, the data of the SBS area of the database RAM is read and the bar information of the SBS broadcast is displayed on the screen. In this state, by pressing the CHANNEL UP / DOWN key, you can see the direct K screen of KBS1 or MBC.

Therefore, in the conventional method, if a user inputs a K key while watching an SBS broadcast, only the K data corresponding to the SBS can be viewed, and the channel K up / down key must be input to view the K data of another broadcasting station. That is, according to the above method, since the user cannot simultaneously view data of several broadcasting stations on one screen, there is a problem in that viewing and reservation can not be made in detail in connection with other broadcasting stations.

Accordingly, an object of the present invention, in order to solve the above-mentioned problems, when displaying a K screen, simultaneously display data of several broadcasting stations on one screen, and search even the unexpressed portion while displaying several program titles on one screen.
