The above objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings by those skilled in the art.

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

1 is a schematic block diagram of a video cassette recorder, which includes a key input unit 10, a microcomputer 20, a tuner 30, a signal processing unit 40, and a deck unit 50.

In such a configuration, the key input unit 10 is provided as an input means for operating the video cassette recorder, and is provided with a plurality of keys including a batch mode mode key, numeric keys, direction keys, and the like to provide a key signal corresponding to a user's key operation. In general, a remote control capable of being input from a remote location is used, and a key signal carried on an infrared carrier wave from the remote control is detected and output.

The microcomputer 20 is a means for controlling the overall operation of the video cassette recorder. As can be seen from the description below, the microcomputer 20 uses the OSD for batch processing based on the batch processing mode key signal from the key input unit 10. On Screen Display) controls the screen output, controls the OSD screen output for selecting a combination of detailed items to be batch processed based on the numeric key signal and the direction key signal from the key input unit 10, The combination is stored in a memory (not shown), and the tuner and modulator 30, the signal processor 40, and the deck unit 50 are controlled to execute a batch processing mode such as executing a selected batch process.

The tuner and modulator 30 outputs a broadcast signal of a channel corresponding to the control of the microcomputer 20 (PLL data for channel tuning) among a plurality of broadcast frequency signals transmitted from the broadcast system. It is configured to receive and output to (RF IN), and modulates the applied video and audio signals to a predetermined channel (for example, channel 3, channel 4) and outputs them to the RF output terminal RF OUT.

On the other hand, the signal processing unit 40 converts the broadcast signal applied from the tuner and the modulation unit 30 or the video and audio signals from the line input terminal LINE IN under the control of the microcomputer 20 as a signal for easy recording. Each line is processed and applied to the deck unit 50, or the video and audio signals reproduced from the deck unit 50 are processed into easy-to-display video and audio signals, so that the line output terminal (LINE OUT), tuner and modulator 30 are processed. Is applied.

In addition, the OSD (On Screen Display) unit in the signal processing unit 40 outputs a synthesized video signal or blue-back signal that reads and outputs a character (font) signal corresponding to the control from the microcomputer 20. do.

The deck unit 50 includes a deck mechanism in which a video tape is loaded, a loading motor, a video and audio head, a head drum, a control head, a drum motor, a capstan motor, and the like, based on the control of the microcomputer 20. The video and audio signals from the signal processor 40 are recorded on the video tape, or the video and audio signals recorded on the video tape are read and output.

Next, a detailed description will be made with reference to the flowchart of FIG. 2 and the OSD screens of FIGS. 3A and 3B attached to a batch process according to a preferred embodiment of the present invention in a video cassette recorder including the above-described configuration unit.

First, the microcomputer 20 determines whether a batch processing mode key signal is applied from the key input unit 10 (step 200).

At this time, when the batch processing mode key signal is applied from the key input unit 10, the microcomputer 20 controls the OSD unit in the signal processing unit 40 to display the OSD screen for batch processing as shown in FIG. 3A (step 202).

The OSD screen at this time is read out and displayed together with the number set for batch processing and the combination of sub-items (combination of auxiliary operation and main operation of the video cassette recorder) stored in the memory (not shown) corresponding to the number.

On the other hand, when the OSD screen is displayed in step 202, the user sees the OSD screen and makes a selection, and the microcomputer 20 determines the user's selection based on the key signal from the key input unit 10 ( Step 204).

At this time, when the numeric key signal is applied from the key input unit 10, it is determined whether a combination of detailed items to be batch processed corresponding to the number corresponding to the numeric key signal is stored in the memory (not shown) (step 206).

Next, if there is no combination of the detail items stored in the memory in step 206, the microcomputer 20 recognizes the fact of the batch processing and displays and controls the OSD screen as shown in FIG. 3B for selecting the detail item combination (step 208). .

At this time, the user views the OSD screen and uses the numeric keys of the key input unit 10 to select detailed items (for example, play, record, rewind, change channel, power on / off, operation time, reservation time, etc.). The microcomputer 20 stores the combination of the detailed items selected based on the numeric key signal from the key input unit 10 in correspondence with the selected number in the not shown memory (step 210), and the illustration is omitted. However, when the batch mode key signal is applied from the key input unit 10, the process returns to the step 202.

In detail, when the user combines the detailed items in the OSD screen shown in FIG. 3B, the playback 1 or the recording 2 or the like typically reproduces the operation time 7 for performing the playback operation or the recording operation. It can be combined after (1) or the detail item of recording (2), and it can be seen that the channel change (4) does not need to select the operation time (7).

On the other hand, the reserved time 8 of the detailed items is a detailed item that can reserve the combined execution time of the selected detailed items similar to the reserved recording function of the video cassette recorder.

Next, if the combination of the detail items is stored in the memory corresponding to the number selected in step 206, the microcomputer 20 recognizes the execution of the batch processing and reads out the combination of the stored detail items corresponding to the selected number. The tuner and modulator 30, the signal processor 40, and the deck unit 50 are selectively controlled to perform a batch process (step 212), and the process ends.

On the other hand, if the user's selection in step 204 is a modification of the set batch processing, that is, when the direction key signal is applied from the key input unit 10, the microcomputer 20 displays the OSD screen as shown in Fig. 3B for selecting a detailed item combination. Control (step 214).

Next, similarly to the step 210, the combination of the sub-items selected by the user is re-stored and corrected in the memory corresponding to the number corresponding to the direction key signal from the key input unit 10 (step 216). Although omitted, if the batch mode key signal is applied from the key input unit 10, the flow returns to the step 202.

On the other hand, when the user's selection is terminated in step 204, that is, when the batch processing mode key signal is applied from the key input unit 10, the batch processing mode ends.

As described above, according to the present invention, there is an effect that it is possible to provide a convenience that can be bundled and executed operations frequently used repeatedly in a video cassette recorder.
