Abstract

The present invention relates to a means for guiding a state when a cassette tape margin is inserted into a set because there is no recording prevention step, and a tape margin that cannot be recorded during a recording operation in a system is conventionally used. It was inconvenient because the tape margins had to be automatically ejected and remanufactured at the time of loading.

According to the present invention, the system checks whether there is a recording key input and checks whether there is a recording prevention step, and if there is no recording prevention step, ejects a tape and sends an ODS guide so that the system can improve such a conventional problem. And a recording prevention step guide processing program (100) including the step of waiting for the system in the recording / pose mode and operating in the recording mode when the tape is inserted with the recording prevention step. The present invention provides a method for guiding anti-recording step of a sial system.

Description

How to process the recording prevention step guide of VSI system

The present invention relates to a tape recording means of VSI, which is particularly used for user guidance when a cassette tape margin is loaded into a set without an anti-tape tape when a blank tape is inserted into a VSIAL deck to perform a recording operation. While outputting the guide screen, the system can wait until the tape is inserted with the recording prevention tab, so that the user can eliminate the inconvenience of operation through a number of key operations.

In a conventional VSI system, a cassette tape margin was charged to a set and a recording switch was pressed to perform recording.

At this time, the side wall of the margin main body opposite to the tape opening of the rectangular cassette tape margin is provided with an anti-tape step that allows the user to record a specific pro and then remove the disc for random recording. When the anti-tape step is removed, Even if the user presses the recording switch, the recording cannot be performed. If the tab is attached, the recording can be performed.

For example, a VSI system circuit that performs a recording operation or the like in connection with the recording prevention step is illustrated in FIG. 1.

In this case, an automatic tuning tuner 55 receiving a regular broadcast signal from an antenna of a VSI system and performing channel tuning, and an intermediate frequency processing of the tuning signal provided by the automatic tuning tuner 55 to generate a video signal and an audio signal IF unit 56, microcomputer 54 for controlling the VSI system, OSD unit 60 for generating the on-screen display screen, VSI system memory 53, and key units for various key operations 65, a deck 63 for recording / playback deck operation, a servo circuit 64 for controlling a drive motor and the like on the deck 63 side, an audio processor 58 and a speaker 59, video The processor 57 includes a processing unit 57, a signal mixer 61, a TV receiver 62, and the like.

In the conventional VSI system, when the user presses the recording switch through the remote control transmitter 51 or the key unit 65 while recording, the microcomputer 54 recognizes this and writes to a blank tape loaded in the deck unit 63. It was to proceed with the recording.

At this time, if the tape margin does not have an anti-tapping step, the recording cannot be performed and the tape is forcibly discharged. If there is an anti-tapping step, the recording is performed as it is.

For example, the recording process related to the anti-tap step in such a system is illustrated as shown in FIG. 2.

Here, the system checks whether the recording key is pressed, and if the recording key is pressed, checks whether the mode is the stop mode again.

In the above stop mode, it is checked whether there is a tap, and when there is a tap, the drum and the capstan are driven, and the step detection port of the microcomputer 54 is outputted to logic 1.

If there is no tap, the tape is recognized as a tape that cannot be recorded and the tape is forcibly extracted.

As described above, when a user inserts a tape margin without a recording prevention tab and performs a recording operation, a user inserts a tape margin without a recording prevention tab → presses a recording button → presses a tape eject → releases a recording mode → has a recording prevention tab. It is necessary to perform the recording work in the order of loading the tape with the tape, press the record button and record mode.

However, in the conventional technology, when the user inserts the tape margin into the set without checking whether or not the tape margin is required for the recording operation, the user must go through the complicated operation process as described above to avoid the inconvenience of using such a system. It was causing.

An object of the present invention is to check that the tape margin is removed when the tape margin is removed in the recording protection state when the tape margin is already inserted into the set of VSI system to improve the above problems It outputs OSD instructions such as inserting a new tape margin and allows users to expect the convenience of using such a system by allowing recording operation without additional manipulation when entering a new tape margin.

In particular, the present invention checks whether there is a recording key input and checks whether there is a recording prevention step, and if there is no recording prevention step, the system ejects a tape and displays an OS message to implement the object of the above example. And a method of processing an anti-tape step input of a VSI system performed by an anti-tape step guide processing program, which includes a step of waiting the system in a recording / pose mode and operating a recording mode when a tape having an anti-tape step is inserted. It is characterized by.

Hereinafter, more specific features of the present invention will be understood by describing the same in detail with the accompanying drawings.

100. Anti-recording step guide processing program

That is, the anti-recording step guide processing program 100 which can implement the anti-tapping step input processing method of the VSI system according to the present invention is illustrated as shown in FIG. 3.

Here, the system checks whether there is a recording key input (step 101), and if there is a recording key input, checks whether there is a recording prevention step (step 102).

After that, if there is no recording prevention step, the tape is ejected and an OS message is displayed (step 104), the system is waited in the recording / posing mode (step 105), and it is checked again whether there is a tape insertion with the recording prevention step (step 105). 106), if there is an insertion, a series of processes are performed to operate in the recording mode (step 103).

The present invention of such a configuration loads a tape margin into a set when a user wants to record using a VSI system.

At this time, the system microcomputer 54 recognizes whether there is a recording prevention tap on the loaded tape as shown in FIG. 1, and if there is no recording prevention step, the system microcomputer 54 outputs the following OSD menu screen through the OS. will be.

Recording Guide Tape Margins loaded into the set are tapes that cannot be recorded. Make sure that there is a recording protection tab, and then insert a tape margin with a new recording protection tab.

Therefore, when the user inserts the tape margin with the recording prevention tab through the screen, the system automatically enters the recording operation even without pressing a separate recording button.

On the other hand, the above operation is performed by the microcomputer 54 together with the recording prevention step guide processing program 100, which checks whether the system has a recording key input, and if there is a recording key input, checks whether there is a recording prevention step. (Step 101, 102).

After that, if there is no record prevention step, the tape is ejected, the OS message is displayed, the system is in record / pose mode, and the tape is inserted again with the record prevention step. (Steps 103 to 106).

Therefore, the user can insert a new tape margin through the information on the tape margin loaded in the set when the recording prevention tab is removed, and recording can be automatically performed when the tape margin is loaded. It is.

In the present invention, when the user inserts a tape in which the recording prevention step is removed when the user performs a recording operation in the VSI system, the recording is automatically performed when the new tape margin is inserted again after providing the OS screen related to the recording. By making it possible, the convenience of such a system can be well pursued.
