Description

  The present invention relates to a system for controlling a separate television receiver having a structure in which a display unit and other parts (hereinafter referred to as a tuner unit) are combined in a separate case so as to be separable, and in particular, such a separate television. The present invention relates to a control method for a separable television receiver in an AV (Audio Video: audio video equipment) system in which an external device is connected to an interface as a root device and routed through an interface connection.

  Conventionally, various AV devices such as a television receiver, a DVD (Digital Versatile Disc) recorder, an HDD (Hard Disc Drive), an audio device, and the like, for example, HDMI (High Definition Multimedia Interface) A system configuration is known in which a connection is made based on a video digital interface standard such as a media interface, the AV device is used as a root device, and root devices are sequentially connected by a route. By using a control method defined by a video digital interface (for example, in the case of HDMI, a CEC (Consumer Electronic Control) method), it is possible to control another device from a certain root device ( For example, non-patent literature Reference).

  FIG. 5 is a block diagram showing a conventional example of such an AV system, where 1 is a separation type television receiver, 2 is an image display unit, 3 is a tuner unit, 4 is a video digital interface, 5 is an amplifier, A DVD recorder, 7 is an HDD, and 8 to 10 are video digital interfaces.

  In the figure, a separation-type television receiver 1 has a configuration in which an image display unit 2 and a tuner unit 3 are configured as separate casings and are separably combined, and the tuner unit 3 has a display screen. The image display unit 2 having a different size or the image display unit 2 having a different manufacturer can be used in combination. The image display unit 2 and the tuner unit 3 are provided with interface terminals for connecting them, so that the image display unit 2 and the tuner unit 3 are communicably connected by the video digital interface 4. .

  Further, here, the tuner unit 2 of the separation type television receiver 1 and the amplifiers 5 and HDDs 7 as peripheral devices are communicably connected by video digital interfaces 8 and 10, respectively, and the amplifier 5 is connected as a peripheral device. It is assumed that the DVD recorder 6 and the video digital interface 9 are communicably connected.

  By such connection, the route from the DVD recorder 6 to the amplifier 5 via the video digital interface 9 and from the amplifier 5 to the tuner unit 3 of the separation type television receiver 1 via the video digital interface 8 A route is formed from the HDD 7 to the tuner unit 3 of the separation type television receiver 1 via the video digital interface 10, and the image display unit of the separation type television receiver 1 is connected from the tuner unit 3 via the video digital interface 4. 2 is formed, and the image display unit 2, the tuner unit 3, and the peripheral devices 5 to 6 constitute a route device constituting the route.

  Such a video digital interface also enables transmission of content such as video and audio, and also enables transmission of a control signal for a control method defined by the standard of the interface. A control line is also configured. Then, in order to enable control signals (commands) to be communicated from one root device to other devices on the route, a physical address (root address) is set (addressed) to each root device. In the following, this route address is assumed to consist of a 4-digit numerical value.

  In the routing system shown in the figure, the image display unit 2 that finally acquires the content acquires the route address (0.0.0.0) in which all digits are “0”, and the tuner unit 3 connected to this acquires the route address. The first digit obtains a route address (1.0.0.0) different from the route address of the image display unit 2, and the amplifier 5 and the HDD 7 connected to the tuner unit 3 are the second digit respectively. The route addresses (1.1.0.0) and (1.2.0.0) which are different from the route address 3 and different from each other are acquired. Further, the DVD recorder 6 connected to the amplifier 5 acquires a loop address (1.1.1.0) whose third digit is different from the root address of the amplifier 5.

  Although not shown, if a peripheral device is further connected to the tuner unit 3, the route address of this peripheral device is (1.3.0.0), and the peripheral device is connected to the amplifier 5. For example, the route address of this peripheral device is (1.1.2.0). If a peripheral device is further connected to the DVD recorder 6, the route address of this peripheral device is (1.1.1.1.1). If a peripheral device is further connected to the HDD 7, the route address of this peripheral device is (1.2.1.0).

  Thus, the root address of the root device is expressed hierarchically according to the position on the route, and the image display unit 2 is set as the root device of the highest hierarchy, and one digit of the root address. The first corresponds to the root device of the highest hierarchy, the second digit of the root address corresponds to the root device of the next higher hierarchy, and the third digit of the root address corresponds to the root device of the next higher hierarchy. The fourth digit of the root address corresponds to the root device of the lowest hierarchy. And in the root address of each root device excluding the root device of the highest hierarchy, the digit corresponding to the root device of the higher hierarchy is retained as the value assigned to the root device of the higher hierarchy. is doing.

As described above, by addressing each root device, a series of routes (connection of devices) is clarified by the route address, and by specifying the route address of the destination of contents and control signals, these are specified. Will be sent to the destination via the route.

When the separable television receiver 1 having the above-described configuration is used, a problem occurs.

  For example, when a command (OSD menu display command) for displaying the OSD menu screen (setting screen) on the image display unit 2 is sent from any peripheral device, the route address (0.0.0.0) is used. When the image display unit 2 is designated as the transmission destination, this OSD menu display command is sent to the tuner unit 3 of the separation-type television receiver 1 through the previous route, and this command is sent to the tuner unit 3. Therefore, the tuner unit 3 sends this command to the image display unit 2 via the video digital interface 4 as it is. However, since the image display unit 2 has only a display function, even if such an OSD menu display command is received, the image display unit 2 cannot function in response to this command. The display command cannot be supported.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram showing a first embodiment of a control method for a separable television receiver according to the present invention. 11 is a serial interface, 12 is a video digital interface, 13 is a peripheral device, and FIG. Corresponding portions are denoted by the same reference numerals and redundant description is omitted.

  In the figure, the first embodiment is similar to the conventional example shown in FIG. 5 in that the image display unit 2 and the image display function having only a part of the image display function and the control processing function for image display are as follows. Although not provided, the tuner 3 having most control processing functions for displaying an image on the image display unit 2 is provided in a separate television receiver 1 having a separate housing, for example, by a video digital interface 12 such as HDMI. In this configuration, peripheral devices 13 such as amplifiers, DVDs, and HDDs are communicably connected. Here, the tuner unit 3 and the image display unit 2 may be connected by the video digital tenter interface 4 or may be connected by the serial interface 11 such as RS-232C.

  When such devices are connected, the tuner unit 3 is connected to a root device in the route in which the image display unit 2 connected to the control line of the video digital interface 4 is a standard, that is, a television receiver. It is confirmed whether or not the device has a function as. As such a confirmation method, it may be performed based on information on the image display unit 2 such as a vendor (manufacturer, etc.) or a model of the image display unit 2, or image display using the video digital interface 4 or the serial interface 11. The function of the unit 2 may be detected. As described above, when the function of the image display unit 2 is confirmed using the video digital interface 4 or the serial interface 11, a device other than the image display unit 2 does not respond, for example, a vendor-specific command may be used. .

  Here, in the first embodiment, the image display unit 2 has almost no function other than the image display function and does not have a function to cope with the control command, and the tuner unit 3 confirms this. The image display unit 2 is recognized as a display unit having only the image display function of the separation type television receiver. First, the self (that is, the tuner unit 3 itself) is recognized as the root device of the control line of the video digital interface. Then, (0.0.0.0) is acquired as the first physical address (route address). In addition, the tuner unit 3 that has acquired the route address in this way has an addressing function for assigning the route address to the device connected thereto.

  The image display unit 2 is provided with a root address by the addressing function of the tuner unit 3 to which the image display unit 2 is connected, and becomes the root device of the control line of the video digital interface. In order that the control command required for 2 can be handled by the tuner unit 3 instead of the image display unit 2, the same route address (0.0.0.0) as the route address of the tuner unit 3 Is given to the image display unit 2.

  In this way, the image display unit 2 becomes a root device having the same root address (0.0.0.0) as the tuner unit 3 in the control line of the video digital interface. Therefore, the image display unit 2 and the tuner unit 3 are integrated, and the root device of the root address (0.0.0.0) as the split-type television receiver 1 is obtained.

  A peripheral device 13 is connected to the division type television receiver 1, that is, the tuner unit 3 by a video digital interface 12 of the same standard as the video digital interface 4, and this connection is recognized by the tuner unit 3 and the peripheral device 13. As in the case of the image display unit 2, if it is confirmed that the connected peripheral device 13 is a device that can cope with the control command, the peripheral device 13 is routed to the tuner unit 3 by the addressing function of the tuner unit 3. The root address (1.0.0.0) next to the address (0.0.0.0) is acquired and becomes the root device of the control line of the same video digital interface. The peripheral device 13 has an addressing function for the peripheral devices connected thereto. Therefore, when the peripheral device 13 is an amplifier and a DVD recorder is connected thereto as shown in FIG. 5, this DVD recorder is a root device having the root address (1.1.0.0) on the same control line. It becomes.

  In this way, a routing system is formed. In this routing system, for example, when an OSD menu display command is transmitted from the peripheral device 13, this command is sent to the image display unit of the split television receiver 1. The transmission destination address at this time is the root address (0.0.0.0) of the image display unit 2, and the tuner of the split-type television receiver 1 is also used. It is also an address for designating part 3. For this reason, the tuner unit 3 that has received this OSD menu display command recognizes that it has been transmitted to itself, and performs possible processing for OSD menu display in response to this OSD menu display command. By this processing, a video signal of the QSD menu screen is created, and the video signal of the QSD menu screen is sent to the image display unit 2 together with a control signal for displaying the video. A command that cannot be handled by the unit 3 (this command can be handled by the image display unit 2) is sent from the tuner unit 3 to the image display unit 2 together with the video signal of the created QSD menu screen. The image display unit 2 receives the video signal of the QSD menu screen and receives this command to perform a control process for a predetermined display, whereby the OSD menu screen is displayed on the image display unit 2. become. When the tuner unit 3 and the image display unit 2 are connected by the serial interface 11, it is of course possible to perform such communication between the tuner unit 3 and the image display unit 2 using this.

  In this way, in the first embodiment, even when the image display unit 2 of the split-type television receiver 1 has only an image display function and a part of the control processing function, the tuner unit 3, the image display unit 2, The OSD menu display command can be dealt with by sharing the part that can be dealt with, whereby the OSD menu screen can be displayed. Even if a control command other than the OSD menu display command is transmitted to the image display unit 2, this can be dealt with by the same processing in the tuner unit 3.

  FIG. 2 is a block diagram showing a second embodiment of a control method for a separable television receiver according to the present invention. 14 is a television receiver, and parts corresponding to those in FIG. A duplicate description is omitted.

  In the figure, the second embodiment is such that a television receiver 14 is connected to the tuner section 2 via a video digital interface 4. In this case, the television receiver 14 is connected to an OSD menu display command or the like. The tuner unit 3 has a function as a root device that can cope with various commands, and by confirming this, the tuner unit 3 obtains a root address (1.0.0.0) and controls the video digital interface control line. In addition, a root address (0.0.0.0) is addressed to the television receiver 14 as a root device of this control line. Other than this, the second embodiment is the same as the first embodiment shown in FIG. In this case, the route address of the peripheral device 13 is (1.1.0.0).

  In this way, the routing system is formed. In this routing system, for example, when an OSD menu display command is transmitted from the peripheral device 13, this command is issued to the television receiver 14. The destination address at this time is the root address (0.0.0.0) of the television receiver 14. Therefore, the tuner unit 3 that has received this OSD menu display command recognizes that it has not been transmitted to itself, and sends this OSD menu display command to the television receiver 14. In response to this command, the television receiver 14 performs a process for displaying the OSD menu. By this process, the video signal of the QSD menu screen is created and the OSD menu screen is displayed.

  As described above, in the second embodiment, when the device connected to the tuner unit 3 is the television receiver 14 having a function as a root device capable of handling the OSD menu display command, the OSD menu is displayed. A display command can be directly acquired by the television receiver and can be dealt with. The same applies when a control command other than the OSD menu display command is transmitted to the television receiver 14.

  FIG. 3 is a block diagram showing a third embodiment of the control method of the separation type television receiver according to the present invention. 2a, 3a and 3b are interface terminals, and the parts corresponding to those in FIG. A duplicate description is omitted.

  In this figure, the third embodiment has the same configuration of the routing system as the first embodiment shown in FIG. 1, and the route address of the tuner unit 3 as viewed from the peripheral device 13 is also the same. (0.0.0.0), the route address (1.0.0.0) is set to the interface terminal 3a connected to the image display unit 2 and the video digital interface 4 in the tuner unit 3, and the tuner. A route address (0.0.0.0) is set in the interface terminal 3b connected to the peripheral device 13 in the unit 3 through the video digital interface 12.

  Here, the route address of the tuner unit 3 viewed from the peripheral device 13 is the route address (0.0.0.0) set to the interface terminal 3b to which the peripheral device 13 of the tuner unit 3 is connected. The route address of the tuner unit 3 viewed from the image display unit 2 is a route address (1.0.0.0) set in the interface terminal 3a to which the image display unit 2 of the tuner unit 3 is connected. In the split-type television receiver 1, the route address is different for each of the interface terminals 3a and 3b of the tuner unit 3.

  In the third embodiment, the tuner unit 3 deals with all the control commands from the peripheral device 13, and the control line of the video digital interface is not connected inside the tuner unit 3. Therefore, for example, when there is an OSD menu display command from the peripheral device 13, the tuner unit 3 responds to all the commands and creates a video signal of the OSD menu screen, and displays a control signal for the display. Necessary signals are generated, and an address (0.0.0.0) is designated from the interface terminal 3a and transmitted to the image display unit 2. The image display unit 2 receives this from the interface 2a and displays the OSD menu screen. However, the command for requesting the video signal of the OSD menu screen to the tuner unit 3 is address (1.0.0.0. 0) is designated and transmitted from the interface terminal 2a to the tuner unit 3. When the tuner unit 3 and the image display unit 2 are connected by the serial interface 11, it is of course possible to perform such communication between the tuner unit 3 and the image display unit 2 using this.

  As described above, the tuner unit 3 has a different physical address for each terminal, and by switching the address according to the communication destination, it is possible to realize communication without defects as in the previous embodiment.

  FIG. 4 is a block diagram showing a fourth embodiment of the control method of the separation type television receiver according to the present invention, in which 15 is an audio amplifier (amplifier), 16 is a speaker, and 17 is a remote controller (remote controller). The parts corresponding to those in FIG.

  In the figure, the fourth embodiment has the same configuration and operation as the first embodiment shown in FIG. 1, but the image display unit 2 receives the remote control code from the remote controller 17 and controls it. It is designed to deal with orders.

  The image display unit 2, the tuner unit 3 and the peripheral device 13 on the control line are addressed in the same manner as in the first embodiment, and the same route address (0) is assigned to the image display unit 2 and the tuner unit 3. 0.0.0) is set, and the route address (1.0.0.0) is set to the peripheral device 13.

  Further, the image display unit 2 is provided with an audio amplifier 15 and a speaker 16 and has a function of receiving a remote control code of a control command from the remote controller 17, and a function of processing this control command. Not equipped. The tuner unit 3 confirms that the audio amplifier 15 and the speaker 16 are included in the components of the image display unit 2. Such confirmation is preferably executed when confirming the function of the image display unit 2 at the time of addressing described in the first embodiment.

  When the remote control code is transmitted from the remote controller 17 in the state where the addressing and the connection device confirmation are completed and the routing system is formed in this way, the image display unit 2 receives the remote control code of the control instruction. And transmitted to the tuner unit 3. The tuner unit 3 receives this remote control code, determines whether or not this is a command for a control process that can be dealt with by the image display unit 2, and if it can deal with it, a control that can execute the control process If the signal is sent back to the image display unit 2 and the command of the control process cannot be dealt with by the image display unit 2, the tuner unit 3 performs the process.

  Here, as an example, a case where the remote control code is a volume control code will be described.

  When a volume control code is transmitted from the remote controller 17 (arrow (A)) and received by the image display unit 2, the image display unit 2 transmits the received volume control code to the tuner unit 3 (arrow (B)). ). The tuner unit 3 determines that the necessary processing for the received volume control code is, for example, control processing of the audio amplifier 15 or volume adjustment OSD display, and further, the control processing of the audio amplifier 15 is performed by the image display unit 2. It is determined that the volume adjustment OSD display is performed by the tuner unit 3. As a result of this determination, the tuner unit 3 transmits a control signal for volume adjustment of the audio amplifier 15 to the image display unit 2 (arrow (c)), and performs volume adjustment OSD display processing to display the volume adjustment OSD display. Is generated and transmitted to the image display unit 2 (arrow (d)).

  Thereby, based on the volume adjustment OSD display, when the user operates the remote controller 17 to obtain a desired volume, the volume control code for designating the volume adjustment amount corresponding to the operation from the remote controller 17 is displayed on the image. A control signal for volume adjustment is sent from the tuner unit 3 to the audio amplifier 15 of the image display unit 2 to control the volume adjustment in the audio amplifier 15.

  The communication between the image display unit 2 and the tuner unit 3 may be performed using the video digital interface 4 or may be performed using the serial interface 11. .

  In this example, the remote control code from the remote controller 17 is a volume adjustment code. However, the present invention is not limited to this, and the same applies to other remote control codes.

  In this way, the remote control code received by the image display unit 2 is transmitted to the tuner unit 3, and the tuner unit 3 determines the optimum process, so that the image display unit 2 is the root device on the control line of the video digital interface standard. Or, even without having some of the necessary functions as a television receiver, it is possible to operate without any malfunction.
