Description

VSI system having the function to execute the operation mode before power failure

The present invention relates to a VSI system having a function of performing a power failure operation mode, in particular, in a state such as a power failure or a set power plug being pulled out from an outlet while a user of a VSI system performs the operation in a operation mode. The operation mode before power failure can be memorized as it is, and after power failure, the operation mode before the power failure can be performed as it is.

The VSI system is a device that receives various video / audio sources from the outside, records them on a tape, and plays and views the recorded tape. A typical type of the VSI system is illustrated in FIG. 1.

In this case, the microcomputer 21 which controls the system of VSI system, the servo circuit 22 which controls the deck part under control of this microcomputer 21, and the remote control receiver connected wirelessly with the remote control transmitter 30 ( The timer circuit 23 to which the 23a and the key part 23b are connected, the audio circuit 25, the video circuit 27, etc. are provided.

The system also includes a DMS (DMSS) circuit 26 for providing an audio signal in a normal state during double speed playback, an OSD processor 24 for displaying a text subtitle on a screen, and a broadcast signal. A tuner for receiving, an IF circuit 28, a power supply circuit 29, and the like are included.

In the conventional system, the tuned channel and the tuned tuner of the tuner and the IF unit 28 are stored in the microcomputer 21 or in a separate EEPROM memory. This operation is performed in the screen interactive storage method through the OSD processor 24.

As an example, an example of the OSD program which presets the auto search of the broadcast signal and the tuned channel is shown as shown in Figs. 2A to 2D.

Here, when the menu button is pressed from the remote control transmitter of the system or the like, a menu screen 31 as shown in FIG. 2A is displayed, and when a number 3 is pressed to set a channel from this menu screen 31, the channel preset screen 32 as shown in FIG. 2B is displayed. ) Is displayed, and when the number 1 is pressed, the manual search screen 33 appears as shown in FIG. 2C.

Then, the user selects the channel and program station name, station number, etc. to be memorized from this screen. To check whether the selected channel, station name, station number, etc. are correctly memorized in the channel requested by the user, press the channel analogy button. It consists of a pressing process.

In addition, when clearing the contents of memory such as a channel from the channel preset screen 32, when the second press is pressed, the channel clear screen 34 as shown in Fig. 2D appears, and the memory channel is cleared through this screen.

In addition, by using this OS function, various functions such as clock setting and weak recording setting can be performed, and the contents thus executed were registered in the system memory.

However, in such a conventional system, there are various system operation modes such as tape advance mode FF / tape reverse mode REW / tape reverse play mode REV / play mode PL, which are general operation modes, in addition to the channel preset operation described above. When an unexpected power failure occurred in the process of performing the mode, even if the above operation mode is stopped and the power failure returns, the operation mode previously performed was not performed unless the operation mode command was issued again.

As such, in the related art, there is no means for connecting the operation mode execution according to the unexpected power outage and return of the power failure during system operation, which causes inconvenience in using such a system.

The object of the present invention is to ensure the convenience of using such a system by remembering the operation mode of the power failure after the return of the power failure even if a power failure or the like occurs in the operation mode of such a system to improve the conventional problems as described above. I did it.

In order to realize the object of the above example, the present invention checks whether the system has a key input command inputted through the key input unit, and checks whether it is an operation mode. A microcomputer to perform control, a memory unit storing operation mode data in key input data under the control of the microcomputer, and a power unit connected to the microcomputer to provide a power failure signal. This is a special feature of VSI system that has the function to perform the operation mode before power failure.

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

That is, FIG. 3 shows a circuit block diagram of a VSI system having a function of performing an electrostatic operation mode according to the present invention.

Here, if there is a key input command input through the key input unit 11, it is checked whether it is an operation mode, and if it is an operation mode, the data is stored in the memory unit 13 and controlled to perform the power failure operation mode after the power failure and the power failure return. It is connected to the microcomputer 12, the memory unit 13 which stores the operation mode data in the key input data under the control of the microcomputer 12, and the microcomputer 12 to provide a power failure recovery signal. It consists of a configuration including a power supply unit 17 or the like.

Here, reference numeral 14 denotes a broadcast signal receiver, 15 denotes a green wood signal processor, and 16 denotes a deck unit.

The present invention of such a configuration is to turn on the power to the system through the power supply unit 17 when the user is turned on (ON) the power switch of the VSI system as shown in FIG.

In this state, the user can insert a tape into the deck unit 16 to record a broadcast signal received through the broadcast signal receiving unit 14, or to play an operation of reproducing a tape containing a specific program.

In the above operation, when the recording command or the playback command, the tape forward, the tape reverse, the tape reverse play, and the like are issued through the key input unit 11, the microcomputer 12 recognizes this and the deck unit 16 is operated. It is driving or controlling the broadcast signal receiving unit 14 and the green wood signal processing unit 15 and the like.

On the other hand, in the VSI operation mode as described above, when the function key input through the key input unit 11 is the operation mode key, the microcomputer 12 stores the data related to the mode currently operated in the memory unit 13.

At this time, the data related to the currently operating mode is deleted.

In this state, when the system has an unexpected power failure, the power supply of the power supply unit 17 is cut off and the system operation is stopped. When the power failure is restored after a predetermined time, the microcomputer 12 stores the memory in the memory unit 13. Pre-outage operation mode After retrieving data, the pre-outage operation mode continues.

This operation is performed by the microcomputer 12 together with the pre-outage operation mode memory program 100 and the post-outage operation mode execution program 200 as shown in FIGS. 4A and 4B.

Here, as shown in Fig. 4A, the system checks whether there is a key input, and if there is a key input, checks whether the operation mode key data is used, and if it is the operation mode key data, the value is stored in the memory (steps 101 to 103).

In addition, in FIG. 4B, the system checks whether the power failure recovery mode is performed by a signal detected through the power supply unit 17, and if the power failure recovery mode, the operation mode data stored in the memory unit 13 is stored before power failure and the operation is performed. (Steps 201 to 203).

The present invention can easily cope with unexpected power failure by remembering the power failure operation mode as it is when the power failure occurs while using the VSI system and automatically performing the power failure mode after the power failure returns.
