Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic view of a video cassette recorder capable of performing the batch processing method according to the present invention and includes a key input unit 10, a microcomputer 20, a tuner and a modulation unit 30, a signal processing unit 40, 50).

The key input unit 10 is an input means for operating the video cassette recorder. The key input unit 10 includes a plurality of keys including a batch mode key, a numeric key, and a direction key to output a key signal corresponding to a user's key operation. And detects a key signal on an infrared carrier wave from a remote controller using a remote controller capable of inputting from a remote site and outputs the detected signal.

The microcomputer 20 is a means for controlling the overall operation of the video cassette recorder. As can be seen from the following description, the microcomputer 20 is an OSD (On Screen) for batch processing based on a batch mode key signal from the key input unit 10. [ The OSD unit 41 controls the OSD unit 41 to output a display screen and controls the OSD screen output for selecting a combination of sub-items to be subjected to batch processing based on the numeric key signal and the direction key signal from the key input unit 10 , And controls the batch processing mode such as storing the combination of the selected detailed items in a memory (not shown) and controlling the tuner and modulation unit 30, the signal processing unit 40, and the deck unit 50 to execute the selected batch process .

The tuner and modulation unit 30 converts a broadcast signal of a channel corresponding to the control of the microcomputer 20 (PLL data for channel tuning) from a plurality of broadcast frequency signals transmitted from the broadcasting system to an RF (Radio Frequency) IN), and outputs the modulated video and audio signals to a predetermined channel (for example, channel 3 and channel 4) to be output to an RF output terminal (RF OUT).

The signal processing unit 40 processes the broadcast signal applied from the tuner and modulation unit 30 and the video and audio signals from the line input terminal LINE IN as easy signals recorded on the basis of the control of the microcomputer 20 The video and audio signals reproduced from the deck unit 50 are processed into video and audio signals that are easy to display and are then applied to the line output terminal LINE OUT or the tuner and the modulator 30 . The OSD (On Screen Display) unit 41 in the signal processing unit 40 reads a character (font) signal corresponding to the control from the microcomputer 20 and synthesizes it into a video signal or a Blue- And outputs it.

The deck portion 50 is a deck mechanism (not shown) in which the video tape is loaded. Such as a loading motor (not shown), a video and audio head (not shown), a head drum (not shown), a control head (not shown), a drum motor (not shown), a capstan motor And records the video and audio signals from the signal processing unit 40 on the video tape under the control of the microcomputer 20 or reads and outputs video and audio signals recorded on the video tape.

FIG. 2 is an operational flowchart of a batch processing method according to the present invention, and FIGS. 3 (a) and 3 (b) are illustrations of an OSD screen in batch processing. The batch processing method shown in FIG. 2 will be described in detail with reference to FIGS. 1 and 3 (a) and 3 (b).

First, the microcomputer 20 determines whether a batch mode key signal is applied from the key input unit 10 (step 200). At this time, when the batch mode key signal is applied from the key input unit 10, the microcomputer 20 controls the OSD unit 41 in the signal processing unit 40 to display the OSD screen for the batch process like the 3a Step 202).

At this time, in addition to the numbers set for batch processing, the OSD screen also reads and displays the combination of the detailed items (combination of the auxiliary operation and the main operation of the video cassette recorder) stored in the memory (not shown) corresponding to the number. Referring to the displayed OSD screen, the user selects a desired function. The microcomputer 20 determines the user's selection based on the key signal from the key input unit 10 (step 204).

As a result of the determination, if a numeric key signal is applied from the key input unit 10, the microcomputer 20 determines whether the combination information of the detailed items to be processed in a batch corresponding to the applied numeric key signal is stored in a memory (Step 206).

As a result of the determination in step 206, if the combination information of the detailed items corresponding to the unshown memory is not stored, the microcomputer 20 recognizes the batch process setting mode and selects the third item (b) So that an OSD screen such as a tile is displayed (step 208).

The user can refer to the OSD screen displayed as shown in FIG. 3 (b) to display detailed items (for example, playback, recording, rewind, channel change, power on / off, operation time, And the microcomputer 20 combines the detailed items corresponding to the applied numeric key signal into an operation to be collectively processed and stores the combined items in a memory (not shown). The storage is made so that the detailed items stored in the current memory (not shown) are collectively processed (step 210) when the number (or number) selected in step 204 is selected.

For example, when the number applied in step 204 is '2' and the number of detailed items stored in step 210 is '3, 6', the user can input numerical values through the OSD screen shown in FIG. When the key '2' is controlled, numeral information for '3 and 6' is read out from the unshown memory, and the corresponding video cassette recorder automatically performs the rewinding mode and then collectively processes the power- . The reservation time (8) of the detailed items is a detailed item that can reserve the combination execution time of the selected detailed items similar to the reserved recording function of the video cassette recorder. When the storage of the selected item in step 210 is completed, the microcomputer 20 returns to step 202. [

On the other hand, if a combination of the sub-items corresponding to the selected number is stored in the memory (not shown) at step 206, the microcomputer 20 recognizes the combination information of the sub-items stored in correspondence with the selected number And performs a corresponding batch process by selectively controlling the tuner and modulation unit 30, the signal processing unit 40, and the tech unit 50 based on the read out combination information (step 212), and ends the operation .

As a result of the determination in step 204, if the user has controlled the direction key in a state where the OSD screen of FIG. 3 (a) is being displayed, the microcomputer 02 recognizes that correction for the set batch process is requested, The OSD screen as shown in FIG. 3 (b) is displayed (step 214).

The information stored in the memory (not shown) is stored in the memory (not shown) so that the combined information of the sub-items selected by the user is re-stored as the batch process information for the number set by the direction key control through the key input unit 10, (Step 216), and then proceeds to step 202 to return.

As a result of the determination in step 204, when the user controls the batch process mode key via the key input unit 10, the microcomputer 20 recognizes the end of the batch process mode and ends the process.

As described above, the present invention provides a method by which a plurality of operation modes can be collectively processed in a single key control by grouping operations frequently used repeatedly in a video cassette recorder, It is possible to provide a menu screen for an operation mode in which a batch process can be performed as well as an operation mode in which a batch process is easily performed even when the user does not memorize the numerical information specified for the operation mode desired for batch processing There is also an advantage to choose.
