  The present invention relates to a video display device having a display unit such as a television receiver, and when an external device connected to a DVD recorder or the like is operated by a remote controller or the like, the operation screen is displayed on the display unit for operation. The present invention relates to a video display device capable of

  In recent years, a system has appeared that connects digital AV equipment compliant with the IEEE 1394 standard to each other via an IEEE 1394 dedicated cable, transmits and receives digital data of video and audio, and records and plays back. Here, the IEEE 1394 standard is a serial SCSI standard capable of transferring a large amount of digital data between a plurality of AV devices at high speed. The IEEE 1394 dedicated cable allows digital AV equipment to be connected in a daisy chain (a daisy chain connection) or a branch connection.

  For example, as shown in FIG. 8 (a), it is possible to daisy chain connect external devices 102 and 103, which are recording / playback devices, to the television receiver 101 via the IEEE 1394 dedicated cable 110. It is. Further, as shown in FIG. 8B, the external device 102 can be connected to the television receiver 101 via the IEEE 1394 dedicated cable 110, and the external devices 103 and 104 can be branched and connected to the external device 102. It is. The position for branch connection is not limited to this, and branch connection is possible from any device.

  In this way, it is possible to control the digital AV device connected by the IEEE 1394 dedicated cable by using a predetermined command conforming to the IEEE 1394 standard. When controlling a digital AV device connected in this way, the OSD screen display function of the television receiver is used to display a GUI (Graphical User Interface) operation screen superimposed on the television image on the television screen, However, by operating an operation button on the remote controller or the digital broadcast receiving apparatus main body based on the displayed GUI operation screen, a command is transmitted to control the external device.

For example, Patent Document 1 discloses a related art relating to performing a recording operation in cooperation with a television receiver and a recording / playback device (external device) connected by an IEEE 1394 dedicated cable. In this case, the playback operation and the recording operation of the external recording device are displayed on the same OSD-displayed operation screen, and are operated by the user.
JP 2003-274297 A

  For external devices that are conventional recording / playback devices, the playback status indicating the content of the playback operation and the recording status indicating the content of the recording operation are displayed on the same control panel (operation screen). There were many operation items (PLAY, REC button, etc.). In particular, recent recording / playback apparatuses have many functions, so there is a tendency for the number of operation items to increase, and the operation screen becomes large. For this reason, when an external device is operated while displaying an image on the image display device, there is a large area hidden by the operation screen, which makes it difficult to view the image that the user originally wants to see.

  In addition, if the playback status and recording status are displayed in the same area on the operation screen, the display itself is switched depending on the function status. It is difficult for the user to determine the current recording status.

  Moreover, in a recording / playback apparatus such as a DVD recorder having an HDD, it is possible to simultaneously record and play back completely different contents. Furthermore, since the IEEE 1394 standard connection cable can connect a plurality of devices, it is also possible to connect a plurality of external devices to simultaneously perform recording and playback. For this reason, when most of the operation details are displayed on a single screen as in the past, the number of operation items becomes very large, and multiple different operations are performed simultaneously on the external device. This makes it difficult to determine which operation the user is currently performing.

  Accordingly, an object of the present invention is to provide a video display device capable of displaying an operation screen that allows a user to easily determine which operation is being performed.

The present invention provides a video display device capable of receiving video / audio information output from any of a plurality of external AV devices and acquiring identification information for identifying the external AV devices.
Registration means for registering the identification information acquired from the external AV device, storage means for storing an operation screen for the user to operate the external AV device, and the user registered in the registration means When any one of the external AV devices is selected, an operation screen corresponding to the selected external AV device is selected from the storage unit, and based on the identification information registered in the registration unit, Control means for generating an operation screen to be displayed, and display means for displaying the operation screen generated by the control means,
The storage means stores a single operation screen that enables all operations on one operation screen, and an operation state operation screen provided for each operation state operation,
The control means determines whether the selected external AV device is a specific type of AV device having many operation items so as to require the operation state operation screen based on the identification information. If there is, an operation screen is generated from the operation state operation screen corresponding to the operation selected by the user, and the operation screen can be switched according to the user's selection. An operation screen is generated from a single operation screen .

Further, the operation state operation screen is constituted by operation items necessary for at least a recording state or a reproduction state of an external AV device.

  The video display device has an interface for connecting to the external AV device, and the identification information is automatically acquired when the external AV device is connected via the interface. It is characterized by.

  Further, the identification information includes at least one of a type, a manufacturer name, a product type name, and a product number regarding each external AV device.

The operation screen can be switched when the control means determines that the selected external AV device is of a specific type.

  When the operation screen display process is performed, at least one of the type, manufacturer name, product model name, and product number related to the selected external AV device is displayed on the screen.

The operation screen is displayed at a corner of the display means .

Further, as the video information displayed on the display unit in the previous period, display processing is performed by selecting the target video information in the operating state of the AV device corresponding to the operation screen display selection operation. To do.

  According to the present invention, since different operation screens are set for each operation state of the external AV device, the total number of operation items in one operation screen can be reduced, and the display area of the operation screen can be reduced. it can. Therefore, when the operation screen is displayed as an OSD image on the video displayed on the video display device, the area hidden by the operation screen can be reduced. In addition, since the display is switched to the operation screen corresponding to the user's operation, it is possible to easily determine which operation the user is performing. This eliminates the possibility of the user performing a recording operation during reproduction.

  In addition, according to the present invention, the identification information of the external AV device is automatically acquired when the external AV device is connected via the interface, so it is necessary to register the identification information by the user's own operation. And usability is improved.

  In addition, according to the present invention, it is possible to perform the switching process when it is determined that the selected external AV device is an AV device having a certain type, that is, an operation device having a large number of operations so as to require a plurality of operation state operation screens. Therefore, only when necessary, the operation screen with the minimum number of operations can be displayed for each operation state.

  Also, according to the present invention, when the operation screen is displayed, information on the selected external AV device is displayed, so it is easy to determine which AV device is operating. I can judge.

  Further, according to the present invention, since the operation screen is displayed at the corner of the image display screen, the area hidden by the operation screen is limited to the corner, and the video displayed on the display screen can be easily viewed.
