Description

[Combination system and operation switching method between electronical devices, among others]

The present invention relates to a combination system in which a first electronic device and a second electronic device are combined into one, and more particularly, to an operation switching device and a method between a first electronic device and a second electronic device constituting a combination system. It is about.

The integration of two or more different devices into a single system is called a 'combination system' or a 'combo-system', sometimes abbreviated as 'combo'. An example of a combination system is a DVDP / VCR combination system that can perform a combination of the functions of a digital versatile disk player (DVDP) and a video cassette recorder (VCR), a digital TV function, and a DVDP function. There is a combination system, and other combination systems are constantly being developed.

In a combination system, one of the most important functions is the freedom of movement from one device to another. Such operation switching is implemented by an input terminal provided in the main body of the combination system, or by an input terminal provided in the remote controller.

1 is a view schematically showing a DVDP / VCR combination system according to the prior art. Referring to the drawings, the DVDP / VCR combination system 100 includes a DVDP 101, a VCR 103, a main body input terminal 105, a remote input terminal 107, an operation switching signal receiver 109, and an operation switching unit. 111 is provided. In addition, the first electronic device 101 includes a first driver 101a for driving the first electronic device 101, and the second electronic device 103 includes a second driver for driving the second electronic device 103. The drive part 103a is provided.

The main body input terminal 105 or the remote input terminal 107 transmits an operation switching signal to the operation switching signal receiver 109 when an operation switching command by the user is input. Here, the main body input terminal 105 refers to a key input terminal provided in the main body of the combination system 100, the remote input terminal 107 refers to a key input terminal provided in the remote controller (not shown). The main body input terminal 105 and the remote input terminal 107 each include a key input terminal for inputting an on / off control command of the first driver 101a and the second driver 103a.

The operation change signal receiving unit 109 receives an operation change signal by a user input through the main body input terminal 105 or the remote input terminal 107. In addition, when the recording medium is inserted into the second driving unit 103a or the recording medium of the first driving unit 101a is discharged during the operation of the first driving unit 101a, the operation switching time signal receiving unit 109 inserts the recording medium. Recognize the discharge control signal as the operation switching signal.

When the operation switching signal receiver 109 receives the operation switching signal, the operation switching unit 111 changes the operation of the first electronic device 101 to the operation of the second electronic device 103 or the second electronic device 103. Is switched to the operation of the first electronic device 101. For example, in the case of the combination system 100 in which the first electronic device 101 is implemented as a video cassette recorder (VCR) and the second electronic device 103 is implemented as a digital versatile disk player (DVDP), video is transmitted through a VCR. If the tray of the DVDP is ejected or an operation switching signal is received through the main body input terminal 105 or the remote input terminal 107 while watching the video, the image being played back by the driving of the VCR is recorded on the DVD by the driving of the DVDP. The image is switched. In the case of the combination system 100 in which the first electronic device 101 is implemented as a digital television (DTV) and the second electronic device 103 is implemented as a DVDP, the broadcast image is generated by the operation of the DTV by the received operation change signal. Is converted to the video recorded on the DVD by the operation of the DVDP.

By the way, the combination system as described above is switched from the operation of one electronic device to the operation of another electronic device by the wrong operation input command, there is a fear that unwanted screen switching occurs. For example, if an eject command of a recording medium that is being played back is incorrectly input or a screen change command is incorrectly input during video playback by a VCR operation or broadcast viewing by a DTV operation, the video screen being played or the broadcast screen being watched is automatically displayed. By switching to another screen, a screen change that is not desired by the user occurs.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a combination system and an operation method thereof which can prevent unwanted screen switching by allowing a user to select whether to switch the operation.
