Furthermore, in the present invention, the VCR deck 118 searches for the VCR tape to be forwarded (FF) or rewinded (REW) in response to a key signal for generating a menu of the VCR transmitted from the key input unit 110, and the key input unit 110. The VCR tape is temporarily played at the preset time or when the preset signal is

In addition, the VCR image menu generating apparatus of the DVD / VCR combo system according to the present invention converts at least one video image screen temporarily reproduced by the VCR deck 118 using the ADC 126 into a digital signal and then converts the digital signal into a digital signal. Video images are grouped and stored in the memory 128 as a VCR image menu. At this time, the memory 128 is composed of a flash memory (flash memory) and the like can be rewritten.

In the present invention, the OSD block 122 adds an OSD screen, such as a menu for controlling system operation and various error messages, to the output unit 124 by adding a menu for controlling system operation to the VCR video signal. Furthermore, the OSD block 122 stores a VCR image menu stored in the memory 128. It generates one OSD screen and delivers it to the output unit 124.

The output unit 124 outputs a video or audio signal of a DVD or a VCR delivered by the selection of the selection unit 120 to a TV 136 or the like connected through an external connection terminal. In particular, in the present invention, the output unit 124 outputs the VCR image menu stored in the memory 128 to the TV 136 as one OSD screen.

Meanwhile, in the apparatus of the present invention, when a key signal for outputting a VCR menu is input from the key input unit 110, the VCR controller 114 loads the corresponding VCR image menu among menus stored in the memory 128 and displays an OSD block. Through the control unit 122, the OSD screen of the VCR image menu is generated and then output to the output unit 124.

3 is a diagram illustrating examples of a VCR video menu created in a DVD / VCR combo system according to the present invention. Referring to FIG. 3, the first and second OSD screens 128a and 128b each include a menu screen in which at least two VCR video screens are grouped.

4 is a flowchart illustrating a method of creating a VCR video menu of a DVD / VCR combo system according to the present invention. 2 and 4, a method of generating a VCR video menu according to an embodiment of the present invention proceeds as follows.

In the DVD / VCR combo system according to the present invention, the VCR controller 114 determines whether a key signal for generating a menu of the VCR is input from the key input unit 110 (S10).

As a result of the determination in S10, when a key signal for creating a menu of the VCR is input, the VCR controller 114 detects whether or not there is a VCR tape in the VCR deck 118. (S12) If no key signal is input, the VCR controller 114 continues with step S10.

As a result of the S12 detection, when the VCR deck 118 detects that there is a VCR tape, the VCR control unit 114 controls the VCR deck 118 to initialize the VCR tape to the front or the rear. (S14)

The VCR control unit 114 controls the VCR deck 118 to temporarily play back the VCR tape. (S16) At this time, the playback time is limited to within a few seconds.

The video and audio signals of the reproduced VCR tape are signal processed through the video / audio processing unit 116. The VCR controller 114 controls the selection, or switching, of the selector 120 so that only the front or the rear screen of the signal-processed VCR tape of the video / audio processor 116 is transmitted to the ADC 126.

The ADC 126 converts the video signal transmitted through the selector 120 into a digital signal and then displays the initial screen of one VCR image menu (for example, Menu 1, Menu 2, Menu 3,...) In the memory 128. Save as (S18)

After the storage of the initial screen is completed, the VCR controller 114 drives the VCR deck 118 to fast forward (FF) or rewind (REW) the VCR tape to search the screen.

During the step S20, the VCR control unit 114 detects whether the VCR tape under screen search is at the end or the beginning (start) in the VCR deck 118. (S22) In other words, the front screen during the initialization process of S14 in the present invention. If stored, the VCR controller 114 controls the VCR deck 118 to forward (FF). If the rear screen is stored during the initialization process of S14, the VCR controller 114 causes the VCR deck 118 to be rewound.

As a result of the S22 detection, when the VCR tape is not detected at the end or the front, the VCR controller 114 detects a signal set from the key input unit 110, for example, a video index search system (VISS) signal for recording the corresponding VCR screen. (S24)

As a result of the determination of S24, when the bis signal is not detected, the VCR controller 114 controls to continue the operation S20. However, when a vis signal is detected, the VCR control unit 114 causes the VCR deck 118 to stop searching the FF or REW screen at the time of detection, and drives the VCR deck 118 to temporarily play back the VCR tape (several seconds). Within) (S26).

The VCR control unit 114 processes the video and audio signals of the reproduced VCR tape through the video / audio processing unit 116 and performs signal processing of the video / audio processing unit 116 according to the switching of the selection unit 120. Only the temporarily reproduced video image screen of the tape is transferred to the ADC 126. Accordingly, the ADC 126 converts the video signal transmitted through the selector 120 into a digital signal, and then converts the video signal into a digital signal, and the same VCR image menu as the initial screen is stored in the memory 128 (for example, Menu 1, Menu 2, Menu 3, ... as a configuration screen. (S28)

After performing step S28, the VCR controller 114 returns to step S20 to repeat the process of searching the screen by fast forwarding (FF) or rewinding (REW) the VCR tape in the VCR deck 118.

When the VCR tape is detected at the end or the front in step S22, the VCR controller 114 groups the video image screens stored in the memory 128 and stores them as one VCR image menu (S30).

After the method of generating the VCR video menu is finished, the VCR controller 114 detects whether a key signal for outputting an arbitrary VCR menu is input from the key input unit 110. (S32) As a result of S32 detection, an arbitrary VCR menu When a key signal for output is input, the VCR controller 114 finds corresponding menu information among VCR image menus stored in the memory 128 and transfers the corresponding menu information to the OSD block 122. Accordingly, the OSD block 122 generates a corresponding VCR video menu as one OSD screen and transmits it to the output unit 124, and the output unit 124 outputs the OSD screen transmitted from the OSD block 122 to the TV 136. (S34-S36)

On the other hand, if the S12 detection result detects that there is no VCR tape in the VCR deck 118, the VCR controller 114 generates an OSD screen for inputting the VCR tape to the VCR deck through the OSD block 122 and outputs the same. (S38)

In the above-described method of generating a VCR menu of the DVD / VCR combo system of the present invention, the VCR deck 118 detects a predetermined time (for example, 5 seconds, 10 seconds, etc.) without the VCR controller S114 detecting a vis signal in step S24. ) Can be changed to play back temporarily. In addition, although the detailed description of the present invention has been described using the VCR control unit 114 as the main control unit in the combo system of FIG. 2, a method of generating a VCR menu through the DVD control unit as the main control unit or a separate integrated control unit will be described later. Various modifications are possible by those skilled in the art within the spirit and scope of the invention described in the claims.

As described above, in the DVD / VCR combo system, the VCR tape is temporarily reproduced at a set signal or at a set time, and the remaining portion is skipped after storing the reproduced screen in a memory.

Therefore, the present invention can shorten the time it takes for the user to find a specific VCR video screen on the VCR tape by providing the user with an OSD screen of the VCR video menu consisting of stored screens.

On the other hand, the present invention is not limited to the above-described embodiment, various modifications are possible by those skilled in the art within the spirit and scope of the present invention described in the claims to be described later.
