Combination System Control Apparatus And Control Method

 The present invention relates to a combination system, and more particularly, to an output control method of a combination system in which a plurality of devices performing independent functions such as DVDP and VCR are combined into one system.

Two or more different devices connected to one integrated system are referred to as a 'combination system' or 'combo-system', which is abbreviated as 'combo'. An example of a combo system is a DVDP / VCR combo system developed to perform a combination of a DVDP function and a VCR function.

1 is a block diagram showing an internal configuration of a combo system of the prior art, in particular, a DVDP / VCR combo system 10 capable of performing the functions of DVDP and VCR.

The DVDP / VCR combo system 10 is output from a VCR unit 80 performing a function of a general VCR, a DVDP unit 20 performing a function of a general DVDP, a VCR unit 80 and a DVDP unit 20. An external signal input unit 40, a VCR unit 80, and a DVDP unit 20, which provide a signal input from an external device such as a selector 30, a camcorder, etc. to perform a selection operation on the signals to the selector 30. On-screen display (OSD) function is added to the output unit 50 for providing signals outputted from the NVR to peripheral devices such as a TV or an amplifier, and video signals output from the VCR unit 80 and the DVDP unit 20. OSD block 60 and the like are provided.

The VCR unit 80 includes a VCR deck 11 for recording a signal on a magnetic tape or reproducing a signal recorded on a magnetic tape, and a video block for processing video and audio signals to be recorded or reproduced for the VCR deck 11. 12 and an audio block 13, a VCR deck 11 and a VCR control unit 14 for controlling the overall operation of the video block 12 and the audio block 13, and the like. In addition, the VCR unit 80 includes a display 16 for displaying information such as its operation state and operation mode to the outside so that the user can know, an operation panel 17 for receiving various commands from the user, and a remote controller ( 70, a remote control sensor 18 for receiving various commands from the user is provided.

The VCR unit 80 also includes a command storage unit 15 for storing various commands. In the command storage unit 15, codes relating to various operation commands necessary for the operation of the VCR unit 80 and the DVDP unit 20 are stored, and each operation command is a command used only in the VCR unit 80. Information about whether the command is used only in the unit 20 or used in both the VCR unit 80 and the DVDP unit 20 is also stored. The VCR controller 14 compares the commands stored in the command storage unit 15 with the commands input through the remote control sensor 18 or the operation panel 17, so that the command inputted only in any device 20 or 80. It may be determined whether the command is used exclusively or whether the command is used in both devices 80 and 20.

The DVDP unit 20 has a DVD deck 21, a DVD servo 22, a DVD control unit 23, a DVD encoder 24, and the like. The DVD deck 21 reads data recorded on the DVD in order to perform a playback operation on the DVD, and the DVD servo 22 performs position control and speed control of the DVD deck 21. The DVD encoder 24 receives the data read by the DVD deck 21 through the DVD control unit 23 and outputs DVD image data and DVD sound data. The DVD controller 23 controls the overall operation of the DVD deck 21, the DVD servo 22, and the DVD encoder 24.

In addition, the VCR controller 14 and the DVD controller 23 are connected to each other to transmit and receive commands.

The output of the DVD encoder 24, the output of the video block 12 and the audio block 13, the signal from the input unit 40, and the like are input to the selector 30. The selector 30 is controlled by the VCR controller 14 and the DVD controller 23 to perform a selection operation on the input signal, and the output of the selector 30 is an OSD block 60 and an output unit 50. Is entered.

The OSD block 60 functions to add an OSD function to the signal input from the selector 30.

The output unit 50 receives signals from the DVD encoder 24, the selector 30, and the OSD block 60, and outputs signals related to the DVD image, the DVD sound, the VCR image, and the VCR sound. A peripheral device such as a TV or an audio device is connected to the output unit 50, and thus the image and sound are output from the peripheral device.

The external signal input unit 40 is connected to the selector 30 and functions to transmit a signal input from the outside to the selector 30. A signal output terminal of an external device such as a camcorder is connected to this external signal input unit 40. Therefore, the signal recorded in the external device can be transmitted to the combo system 10 through the external signal input unit 40, and can also be recorded on the magnetic tape using the VCR unit 10 or reproduced through the TV. .

Usually, the operation panel 17 and the remote control 70 are provided with a plurality of operation buttons. These buttons include the play / pause button, the record button, the stop button, the eject button, the forward fast button, and the rewind button. It includes (not shown).

As described above, the combo of the prior art is used to distinguish between the VCR-only key, the DVDP-only key, or the public key among the input keys.

In other words, the play command and the pause command are operated by one operation button. When the play / pause button is first pressed, it is recognized as a play command and when it is pressed again, it is recognized as a pause command.

That is, the VCR control unit 14 controls the VCR deck 11 to play the signal recorded on the magnetic tape when the current operation mode is the VCR mode when the play command is input, and if the current operation mode is the DVD mode, the VCR control unit 14 It transmits to the control part 23. The DVD controller 23 controls the DVD deck 21 to reproduce the signal recorded on the DVD as the playback command is transmitted. On the other hand, when the play / pause button is pressed during the play operation of the VCR unit 80 or the DVD unit 20, the play operation of the device 20 or 80 currently in play operation is stopped.

Forward fast commands, rewind commands, stop commands, and eject commands are operation commands common to both devices 20 and 80, and both operation modes and re-entry are considered. . Accordingly, when the fast forward button, the rewind button, the stop button, or the eject button is pressed, such a command is input, the device 20 or 80 corresponding to the set operation mode first performs the input operation command. That is, when the current operation mode is the VCR mode, the operation input by the VCR unit 80 is performed. When the current operation mode is the DVDP mode, the operation input by the DVDP unit 20 is performed. Then, when the same operation command is input again, the operation command inputted again is transmitted to the other device 20 or 80, and the operation command input by the received device 20 or 80 is performed.

However, the stop command is not only when the same operation command is actually re-input, but also when the operation of the device 20 or 80 corresponding to the set operation mode is already stopped or the device corresponding to the operation mode is not operated. If not, the same operation command is determined to be re-entered.

Since the record command is executed only in the VCR unit 80, the operation mode and re-input or not are not considered. Therefore, when the recording button is pressed and the recording command is input, the VCR controller 14 controls the VCR deck 11 to record the input signal on the magnetic tape.

According to the type of each operation command as described above, the conditions that are applied among the various conditions, such as whether the operation command common to each device 20, 80, set operation mode, whether to re-enter the operation command, etc. As a result, when the user presses a certain operation button, it is possible to perform a proper operation corresponding to the actual operation intention of the user.

However, when implementing a combo system that combines more and more complex devices by adding new functions to the combo system as described above, the product becomes complicated and thus difficult to use due to the increase of the function keys for controlling each system. .

 In particular, in an environment where the use of storage devices is activated, the above-mentioned combo system stores image information recorded in a large memory device, and if necessary, reproduces the image information and transmits the image information recorded on another playback medium.
