BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a device capable of making a reservation recording of a broadcast program such as a VCR (Video Cassette Rrcorder). The present invention relates to a menu control apparatus and method for making reservation recording by using a menu control apparatus using the same.

In general, reservation recording in a device that can reserve a broadcast program such as a VCR is performed as follows.

First, when a user inputs information about a broadcast program to schedule recording and turns off the power, the VCR compares the reservation recording start time with the current time. As a result of the comparison, if the scheduled recording start time and the current time coincide, the reserved program is recorded after the power is turned on. During recording of the reserved program, it is determined whether the scheduled recording is completed. If the scheduled recording is to be completed, the recording is completed and then the power is turned off. At this time, if there is a separate tuner in the VCR, recording of the reservation recording program proceeds when the corresponding reservation time arrives while watching a program of another broadcast through the TV.

However, conventionally, a lot of information about a program has to be input in order to perform a reservation recording. That is, the start time (year, month, day, hour, minute), end time, repeat board (NOMAL, DAILY, WEEKLY) and VCR of the broadcasting station's channel and program through the data (newspaper or TV information sheet) on which the program is written. The speed mode (SP, LP, SLP) must be set.

In particular, the information input process for the program is very complicated, and the user has been inconvenient by inputting the channel, date, start time and end time in numbers. Recently, in order to eliminate the inconvenience, a method of using a code has been developed to simplify reservation recording.

However, in such a method, since several programs of each broadcasting station must be coded, not only a large number of user inputs but also a reservation recording cannot be performed when data on which a broadcast program is written is damaged.

As a way to improve this, when a broadcast station transmits a broadcast signal to each home, the program schedule data for reservation recording is transmitted as a broadcast signal in a band where the broadcast signal that can be actually watched is not loaded, that is, VBI (Vertical Blanking Interval). There is a way. This allows a user to execute a scheduled recording while viewing a screen and checking a program by displaying a menu for the reserved recording on the screen without the user having to check various information of the broadcast program.

1 is a block diagram of a conventional menu control apparatus.

The broadcast signal received through the aerial line is input to the data separator 1 and the display controller 2. The data separator 1 separates and outputs only program schedule data from the input broadcast signal.

The program schedule data may include channel data, broadcast date data, start time data, end time data, title data, classification code data, current time data, and the like.

Such program schedule data is information previously promised between a broadcasting station and a receiving side, and the broadcasting station continuously transmits program schedule data in a predetermined unit.

The data detector 2 inputs the data separated by the data separator 1 to detect the error correction and the respective data included in the program schedule data described above, and store the data in the first memory 3.

The first memory 3 is for storing information on a predetermined unit of broadcast program transmitted from a broadcasting station, and stores data for each piece of information output from the data detector 2.

The second memory 4 temporarily stores information for displaying on one screen. The second memory 4 stores background information data for a background screen, variable information data such as time, date, or current time according to a program, and program title data. do.

The third memory 5 has a lookup table for converting the background information data which does not change on the screen and the data stored in the second memory 4 into characters that can be viewed by the user under the control of the microcomputer 8. The look-up table has character bits that can be viewed by the viewer with data inputted as addresses.

The command applier 7 may be a means for a user to input a command for reservation recording. For example, in the case of a remote controller, the command applier 7 may assign a key according to a menu selection to the front panel of the remote controller to apply a command.

When the user selects the menu selection screen for reserved recording through the command granting unit 7, the microcomputer 8 selects the necessary data from the first memory 3 to display the necessary data on one screen of the second memory 4. Is stored in the second memory 4, and the third memory 5 controls to convert one screen of data stored in the second memory 4 into character bits.

The display control unit 6 is for OSD (On Screen Display) of the characters for the broadcast program, and combines the image signal received through the aerial with the characters for the broadcast program output from the third memory (5) display means ( (Not shown).

Such a conventional menu control device has a problem that the processing speed is slow because the microcomputer is dedicated to the control of each memory. In addition, if a large amount of data needs to be processed, for example, the program schedule data contained in the broadcast signal must be compared and searched in a sort mode for searching a specific program on a specific day. It has a lookup table that converts it into characters that can be viewed. The look-up table has character bits that can be viewed by the viewer with data inputted as addresses.

The command applier 7 is a means for a user to input a command for reservation recording. For example, in the case of a remote controller, the command applier 7 may assign a key according to a menu selection to a front panel of the remote controller and apply a command.

The user selects a menu selection screen for reserved recording through the command granting unit 7, and the microcomputer 8 selects the necessary data from the first memory 3 to display the necessary data on one screen of the first memory 4. Is stored in the second memory 4, and the third memory 5 controls to convert one screen of data stored in the second memory 4 into character bits.

The display control unit 6 is for OSD (On Screen Display) of the characters for the broadcast program, and combines the image signal received through the aerial with the characters for the broadcast program output from the third memory (5) display means ( (Not shown).

Such a conventional menu control device has a problem that the processing speed is slow because the microcomputer is dedicated to the control of each memory. In addition, when a large amount of data needs to be processed, for example, in a sort mode for searching for a specific program on a specific day, the program schedule data contained in the broadcast signal must be compared and searched. There was a problem of rising costs.

Step 101), determining the movement of the cursor to obtain the address of the first memory according to the cursor position (step 102), and obtaining the maximum number of specific types of programs for sorting in the sort mode (Step 103 ~ Step 107), storing the variable information data in the second memory (step 108), obtaining the address of the first memory according to the cursor position in the sort mode (steps 109 to 110), and a screen maximum value. Storing the screen information data in the second memory up to the maximum value or the program maximum value (step 111), storing the screen information data in the second memory up to the maximum value value (step 112), and disrespect The process of applying to the play control unit (step 113).

5 is a view showing a screen state to explain the present invention.

Next, the operation of FIGS. 2 and 3 will be described in detail with reference to FIGS. 4 and 5.

The broadcast signal received through the air line is separated into program schedule data only in the data separator 10, and the data detector 20 inputs the separated data from the data separator 10 and stores the data in the first memory 30. The data is converted into data and stored in the first memory 30.

When the user applies the menu control command to the command application unit 70 for the reserved recording, the microcomputer 80 outputs a system control signal according to the command of the command application unit 70. In this case, the system control signal may be a signal for menu control or a signal for sort mode during reservation recording. When a menu control command is input to the menu control unit 90, an initial screen indicating the first program of the day up to the screen maximum value is displayed on the display means (not shown) and provided as a background image stored in the third memory 50. The data DATA3 is stored in the second memory 40 through the second memory data MUX 926 (step 101). For example, in FIG. 5, the underlined characters in lines (1) and (2) are preset background information irrespective of the position of the cursor.

The following steps show the process of composing a screen as a process of vertical sync.

When the user moves the cursor to see another program, the cursor control signal is applied to the menu controller 90 according to the movement of the cursor in the microcomputer 80 through the command application unit 70. That is, the user can control the movement of the cursor by using the up key ↑ or the down key ↓ in FIG. 5.

When a cursor control signal according to the movement of the cursor is applied, the cursor control unit 911 obtains a program rank according to the position of the cursor (step 102). In the main mode, the program rank is used as an address of data for a program stored in the first memory 30 as it is. That is, the first memory address control unit 913 inputs the program rank obtained by the cursor control unit 911 to output the first memory address. The cursor controller 911 may include a page controller (not shown) for adjusting the movement of the cursor in units of pages in order for a user to quickly search.

However, in sort mode, the program that appears on the screen should be the specific program you want to sort, not the entire program. When the sort mode command is applied through the command application unit 70, the microcomputer 80 applies a system control signal indicating the sort mode to the menu controller 90 (operation 103). The system controller 931 enables the sort controller 912 by a system control signal indicating the sort mode, and the sort controller 912 calculates the maximum number of specific programs (step 104). When the sort control unit 912 calculates the number of specific programs, if there is no specific program (step 105), a screen for notifying the user that there is no specific program may be displayed (step 106). If the user selects another date among the search programs through the command applier 70, the process returns to step 101 to display a new initial screen and store the background data in the second memory 40. Otherwise, the screen indicating that there is no specific program is continuously displayed (step 107).

Next, the variable information data is stored in the second memory 40 (step 108). The variable information is underlined characters in lines (1) and (2) of FIG. 5 and may be a current time, date, broadcast station name, broadcast date of a currently displayed program, and the like. At this time, in the case of the current time information, the time compensator 924 transmits the error signal detected by the data detector 20 to the microcomputer 80 when the time data DATA21 of the data contained in the broadcast signal includes an error. The current time information data is output to the second memory data MUX 926 by using the time of the clock of the microcomputer 80 as the effective time. In addition to the current time information, information corresponding to the cursor position is output through the second memory data MUX 926 in step 102.

After the screen information other than the program is stored in the second memory 40, the screen information about the program is stored. In the sort mode (step 109), the program rank obtained in step 102 is different from the program rank in the main mode.

Table 1 shows that all program ranks show classification codes and sorted program ranks. All program ranks show the sequence of programs in order from the first broadcast among information received from a broadcasting station, and a classification code indicates a specific broadcast. For example, 1 is news, 2 is drama, 3 is sports relay, 4 is foreign currency, etc., and the sorting program rank is sorted by the classification code when the user wants to record a specific program only. Indicates a rank.

As shown in Table 2, the program rank in the sort mode is not the rank of all programs, but a program rank obtained by sorting only a specific program.

Therefore, in the sort mode, the total program rank must be obtained from the sort program rank of the program where the cursor is located (step 110). For example, if a user wants to pre-record a drama and selects a desired program while watching only the drama instead of watching the entire program, the cursor moves only in the program for the drama. At this time, if you select sort program ranking 2 among the dramas, the total program ranking is 6.

Screen information data is stored in the second memory 40 up to the screen maximum value or the maximum number of programs obtained in step 104 using the total program rank obtained in step 110 (step 111). According to FIG. 5, the maximum screen value is 7 (3 to 9 lines). The cursor data synthesizing unit 922 stores the cursor position information output from the cursor control unit 911 in the second memory 40 according to the second memory address generated by the second memory address control unit 921. The data is converted into cursor position information and output to the second memory data MUX 926, and the data converter 923 is stored in the first memory 30 by the first memory address output from the first memory address controller 913. The data DATA1 is input, converted into data for storage in the second memory 40, and output to the second memory data MUX 926. The second memory data MUX 926 is output from the cursor data synthesis unit 922, the data converter 923, the time compensator 924, and the third memory controller 925 under the control of the system controller 931. The data is multiplexed and stored in the second memory 40, where each line is stored in the second memory 40 and stored up to seven lines, the maximum screen value. If the maximum number of programs obtained in step 104 is smaller than the screen maximum value, the maximum number of programs is obtained.

In the main mode, the screen information data is stored in the second memory 40 up to the screen maximum value using the program rank obtained in step 102 (step 112).

When all of the screen information is stored in the second memory 40, one screen information data is converted into a viewable character bit by a look-up table stored in the third memory 50, and is output to the display controller 60 to be displayed on the screen. (Step 113). At this time, the third memory controller 925 outputs a third memory control signal and an address to the system controller 931 under control. In addition, the first and second memory control signal generators 932 output the first and second memory control signals under the control of the system control unit 931.

If one screen is displayed, the process returns to step 102 to obtain data for displaying one screen and display the next screen.

As described above, the apparatus and method for menu recording during reservation recording according to the present invention controls the menu through subtitles displayed on the screen instead of the microprocessor in the system for controlling the menu by using the broadcast signal containing the program schedule data. By providing a menu control apparatus and method having a menu control means possible, there is an advantage that the processing speed of the menu control can be increased, and the production cost can be reduced by the simple manufacture of the microprocessor.
