Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that the number of times of operations until being switched to a desired signal is increased with the going-back of a switching order of input signals in the case of switching the input signals by the fixed switching order of the input signals in a video display device having a large number of inputs of a composite, a color difference, a game, an HDMI, etc. <P>SOLUTION: The input signals are grouped to kinds of signals, and the groups are replaced to change the switching order of the input signal so as to reduce the switching procedure of the input signals.

Description

  Video display device comprising input means, selection means, and output means, such as a television, a video playback device, and a selector

  When a recording / playback device is connected to a TV with a plurality of video / audio input terminals, the input switching operation is performed until the target video is displayed. As the number of inputs increases, the number of input switching operations has also increased.

  In the early days of televisions with video and audio input terminals, the number of terminals was about one or two, and the number of input signals was about one or two. However, there are many in current TVs, and there are five types of signals that can be input at 10 input terminals. As an input switching operation method, there is a method in which an input is switched according to a predetermined order each time an input switching button is pressed. In the case of this method, in a TV with little input, the number of operations of the input switching button is small when switching to the target video, and this is not a problem. However, the later the input switching order is on a television with more inputs, the more input switching buttons are operated, and the time and effort required for switching increase.

  Therefore, as a means for minimizing the number of times of pressing the input switching button, there is one using a function for selecting whether the input from the input terminal is valid or invalid. (See Patent Document 1). The following shows an AV device that minimizes the number of times of pressing the number of input switching buttons disclosed in the conventional example.

FIG. 1 shows an AV device capable of sequentially switching input / output terminals, and is provided with a terminal data register for holding data in which input / output terminal switching valid / invalid is set. The switching selection unit 101 is controlled so as not to switch the input / output terminals selected, and the video source display control is performed in accordance therewith, so that the sequential switching of unused input / output terminals is omitted. Thus, since only the video / audio source connected to the input terminal is sequentially switched, the number of key operations at this time can be minimized, so that the feeling of use is improved. In addition, enabling the switching enable / disable setting in the service mode and setting the function related to the input / output terminals corresponding to the model using the same board, chassis, etc., will obtain model variations at a minimum cost It is something that can be done.

  However, in the above configuration, the input signal that has been invalidated is skipped in the video switching operation, but the input signal switching order is fixed and the input signal switching order cannot be changed in the order desired by the user. There was a problem.

  The video display device according to the first aspect of the present invention is an input order for switching the order of the first terminal group for the first input signal, the second terminal group for the second input signal, and the terminal group of the input signal. The switching means, the storage means for storing the order of the terminal group of the input signal, and the input signal is stored in the storage means by changing the order of the terminal group by the input order switching means, thereby reducing the input switching procedure. The order of signal switching is variable.

  By grouping input signals into signal types, switching groups, and reducing the input signal switching procedure, the number of operations before switching to the desired signal can be minimized by changing the order of input signal switching. .

  The best mode for carrying out the present invention will be described below with reference to the drawings.

(Embodiment 1)
The configuration of the video display apparatus according to the first embodiment will be described with reference to FIG. In FIG. 2, the input signal switching means 201 includes composite 1 input terminal 202, composite 2 input terminal 203, composite 1 input terminal 204, color difference 1 input terminal 205, color difference 2 input terminal 206, and iLINK input terminal. 207, a PC input terminal 208, and an HDMI input terminal 209, to which devices are connected. When the input switching signal 210 enters the CPU 211, the input signal is read from the input signal switching unit 201 based on the information stored in the switching order storage unit 214, and the input signal is displayed on the output unit 215. When the input setting signal is input, the input signal switching order is called from the switching order storage unit 214, the OSD is generated by the OSD generation unit 213, and is output to the output unit 215. After changing the input signal switching order, it is stored in the switching order storage means, and the switching order is adopted thereafter.

  Next, the case where the order of input signal switching is changed as desired by the user will be described with reference to FIGS. FIG. 3 is a diagram showing the input signal switching order before the setting change, and FIG. 4 is a diagram showing the input signal switching order after the setting change. FIG. 5 shows a flowchart for switching from the order of FIG. 3 to the order of FIG.

  In FIG. 5, first, the user presses the menu button (S501), and the OSD of the menu is displayed on the display (S502). The input signal switching order item is selected from the displayed menu (S503), and the OSD in the current setting state is displayed on the display (S504). If you do not want to change the setting, select “Do not change” and exit. When changing the setting, select “Change setting” to determine and store the input signal switching order in order from the input item group with the highest ranking (S505, S506, S507).

  According to such a configuration, the number of operations until switching to a desired signal can be achieved by changing the order of input signal switching so that the input signals are grouped into signal types, the groups are switched, and the input signal switching procedure is reduced. Can be minimized.

  In the present invention, the video display device is described as an example, but the present invention is not limited to the video display device, and any device having a plurality of input terminals and display means may be used.

  The video display device according to the present invention is useful as a display device including input means, selection means, and output means because the input signal switching order can be set and changed in the order desired by the user.
