The present invention relates to a peripheral control system, a display device, and a peripheral, and to a peripheral control system enabling a display device to operate a peripheral connected to the display device, a display device making up the system, and a peripheral.
Up until now, it has been performed to operate peripherals such as a recorder, a player, an STB (Set Top Box), and an AV amplifier through a television apparatus (TV) by connecting the peripherals to the television. For example, Patent Document 1 describes a television set capable of displaying, on its screen, operation panels for operating the peripherals. In the case of the television set described in Patent Document 1, when a menu display key of a remote control is depressed, there appear selectably on the screen a VTR, a VHD, a BS tuner, a teletext receiver, etc., as peripherals connected to the television set. Then, when the user operates the remote control to selectively specify one of the peripherals, an operation panel corresponding to the specified one appears on the television screen.
In the method described in Patent Document 1, however, the television prepares in advance the operation panels for the peripherals and changes over the operation panels in response to a specification from the user, and therefore, the television is merely allowed to connect to only the predetermined peripherals at all times. That is, the television retains in advance operation panels for specified peripherals, and hence, if the specified peripherals are connected, the television can display operation panels corresponding thereto, but if a peripheral other than the specified ones is connected, the television cannot display any operation panel since it retains no corresponding operation panel.
In this manner, when operating peripherals through the television, the operation has hitherto been limited to peripherals corresponding to operation panels retained in advance by the television, as a result of which even if the user tries connecting a new peripheral to the television, the operation through the television may be difficult to perform, leading to a problem of lacking in the expandability in the operation of the peripherals.
The present invention was conceived in view of the above circumstances, and it is an object thereof to provide a peripheral control system, a display device making up the system, and a peripheral, the peripheral control system capable of enhancing the expandability in the operation of peripherals, by enabling the customization and display of operation panels for each of the peripherals irrespective of whether the display device retains the operation panels.

Referring to the accompanying drawings, preferred embodiments will now be described of a peripheral control system, a display device configuring the system, and a peripheral, according to the present invention. The embodiments of the present invention will describe a case where the display device and the peripherals are connected to each other via an HDMI (High Definition Multimedia Interface).
More specifically, a function of HDMI Ethernet (registered trademark) Channel (hereinafter, referred to as HDMI HEC) in which two-way communications of Ethernet (registered trademark) signals are carried out through an HDMI cable is added in HDMI standard (version 1.4) published on May 28, 2009. This HDMI HEC-enabled HDMI is utilized. Naturally, the other communication means may be utilized such as HDMI CEC (Consumer Electronics Control), IEEE1394, LAN (Local Area Network), PLC (Power Line Communications), radio communication, and optical communication.
The HDMI will now be simply described. The HDMI is a digital interface for digitally connecting the TV and the peripherals and is adapted for the AV device by adding an audio transmission function and a copyright protection function to DVI that is connection standard specifications for the PC and the display. Until now, a plurality of cables for respective signals for video, audio, and control have been used for connecting the TV and the peripherals, but the HDMI merely requires a single cable so that wiring between the TV and the peripherals can be simplified.
Basic specifications as the standard for HDMI were formulated (HDMI standard version 1.0) in December, 2002 by HDMI Licensing, LLC that is a standardization organization, and thereafter the provision of CEC (Consumer Electronics Control) was added thereto as a control protocol for performing the control between AV devices in December, 2005 (HDMI standard version 1.2a).
Terms on CEC are defined in HDMI standard “2.2. Glossary of Terms”, “CEC 2.2 Glossary of Terms”, etc., in which a Sink device is defined as one having an HDMI input terminal to display output an AV stream, with a Source device defined as one having an HDMI output terminal to output the AV stream, and with a Repeater device defined as one having both the HDMI input terminal and the HDMI output terminal to input and output (transfer) the AV stream.
The HDMI standard defines a device-to-device control using the CEC. This CEC enables various controls based on proper physical addresses and logical addresses allocated to peripherals existing on an HDMI network. For example, if a DVD player connected via the HDMI is reproduced when the user views digital broadcasting, the television automatically performs a switch to the input to which the DVD player is connected. The remote control of the television may be used to operate a menu displayed on the DVD player or the power on/off thereof.
The HDMI cable 40 includes a TMDS (Transition Minimized Differential Signaling) line 41 that transmits a video/audio stream as digital signals in a differential mode, a CEC line 42 that is a bidirectional bus for transmitting a control signal (CEC message) common to the peripherals, and an HEC line 43 that performs a two-way communication of the Ethernet (registered trademark) signal. The HDMI cable 40 further includes an I2C line that is used e.g., for sending EDID (Extended Display Identification Data) or for HDCP (High-bandwidth Digital Content Protection System) authentication.
The recorder 10 is provided with an HDMI transmitter 11, a main microcomputer 12, a front microcomputer 13, a CEC I/F 14, a communication I/F 15, a remote control light receiving portion 16, an HDMI connector 17, a LAN I/F 18, and a memory portion 19.
The HDMI transmitter 11 is connected via the HDMI connector 17 to the TMDS line 41 inside the HDMI cable 40, and reads out video data and audio data recorded in a recording medium such as a BD or a DVD for example to convert into an HDMI format stream consisting of video signals and audio signals interposed in blanking periods of the video signals. The stream obtained by the conversion is transmitted through the TMDS line 41 to the TV 20.
The main microcomputer 12 is a main CPU that controls the entire device and includes an HDMI controller to control the actions of the HDMI transmitter 11 and the LAN I/F 18.
The CEC I/F 14 is connected via the HDMI connector 17 to the CEC line 42 inside the HDMI cable 40 and enables a two-way communication of the CEC message with the TV 20. The action of the CEC I/F 14 is controlled by the front microcomputer 13 that includes a CEC controller, enabling the HDMI connected devices to be controlled by the CEC message. In the case of the CEC, the logical address (the device type) and the physical address (the device position) of each of the HDMI connected devices are acquired so that the CEC message can be sent to a desired device by specifying these logical address and physical address.
The front microcomputer 13 works with a low electric power and monitors at all times the CEC message transferred from the CEC line 42. The front microcomputer 13 is a sub-CPU that controls the remote control light receiving portion 16 receiving a remote control signal from a remote control device not depicted. Then, even when the main microcomputer 12 is powered off during the device standby mode, etc., the front microcomputer 13 operates and keeps enabling the sending/reception of the CEC message and the reception of the remote control signal.
The communication I/F 15 serves to perform a communication with the TV 20 via other means than the HDMI, allowing a connection with the TV 20 through communication means such as IEEE1394, LAN, PLC, radio communication, and optical communication, for example.
The LAN I/F 18 is connected via the HDMI connector 17 to the HEC line 43 inside the HDMI cable 40, to enable a two-way communication of the Ethernet (registered trademark) signals with the TV 20. The LAN I/F 18 may be incorporated within the HDMI transmitter 11.
The memory portion 19 is a nonvolatile memory such as an EEPROM (Electrically Erasable and Programmable Read Only Memory) that stores the logical addresses and the physical addresses in the HDMI and stores image data for operation buttons which will be described later. The memory portion 19 is accessed as needed by the front microcomputer 13 or the main microcomputer 12 for the execution of data reading or writing. The memory portion 19 is not limited to the EEPROM, but instead it may be for example an HD (hard disc), a flash memory, etc.
The TV 20 is provided with a main microcomputer 21, an HDMI receiver 22, a monitor microcomputer 23, a CEC I/F 24, a communication I/F 25, a remote control light receiving portion 26, an HDMI connector 27, a LAN I/F 28, a memory portion 29, and a display portion 30. A tuner is not depicted.
The HDMI receiver 22 is connected via the HDMI connector 27 to the TMDS line 41 inside the HDMI cable 40 and receives a stream transferred from the recorder 10. The HDMI receiver 22 may be incorporated within the main microcomputer 21.
The main microcomputer 21 is a main CPU that controls the entire device and includes an HDMI controller to control the actions of the HDMI receiver 22 and the LAN I/F 28.
The CEC I/F 24 is connected via the HDMI connector 27 to the CEC line 42 inside the HDMI cable 40 and enables a two-way communication of the CEC message with the recorder 10. The action of the CEC I/F 24 is controlled by the monitor microcomputer 23 that includes the CEC controller, enabling the HDMI connected devices to be controlled by the CEC message.
The monitor microcomputer 23 works with a low electric power and monitors at all times the CEC message transferred from the CEC line 42. The monitor microcomputer 23 is a sub-CPU that controls the remote control light receiving portion 26 receiving a remote control signal from a remote control device R. Then, even when the main microcomputer 21 is powered off during the device standby mode, etc., the monitor microcomputer 23 operates and keeps enabling the sending/reception of the CEC message and the reception of the remote control signal.
The communication I/F 25 is intended to perform a communication with the recorder 10 via other means than the HDMI, allowing a connection with the recorder 10 through communication means such as IEEE1394, LAN, PLC, radio communication, and optical communication, for example.
The LAN I/F 28 is connected via the HDMI connector 27 to the HEC line 43 in the HDMI cable 40 and enables a two-way communication of the Ethernet (registered trademark) signals with the recorder 10. The LAN I/F 28 may be incorporated within the HDMI receiver 22.
The memory portion 29 is a nonvolatile memory such as the EEPROM that stores the logical addresses and the physical addresses in the HDMI and that stores operation panel information which will be described later. The memory portion 29 is accessed when necessary by the monitor microcomputer 23 or the main microcomputer 21 for the execution of data reading or writing. The memory portion 29 is not limited to the EEPROM, but instead it may be for example the HD (hard disc), the flash memory, etc.
The display portion 30 is configured from a display such as an LCD (Liquid Crystal Display). In the TV 20, video/audio of the stream is separated by the HDMI receiver 22 and, if required, predetermined video signal processing and audio signal processing are performed to display a video on the display portion 30 and a sound is output from a loudspeaker (not depicted).
A main feature of the present invention lies in that the expandability in the operation of peripherals can be enhanced by making it possible to customize and display the operation panels on a peripheral-by-peripheral basis irrespective of whether the display device retains the operation panel. In the above example, the display device and the peripheral correspond respectively to the TV 20 and recorder 10.
The TV 20 has the memory portion 29 corresponding to a first memory portion that operation panel information including array information for arranging, on the screen, image data for operation buttons making up the operation panel of the recorder 10. The recorder 10 is provided with the memory portion 19 corresponding to a second memory portion that stores image data for operation buttons and the LAN I/F 18 corresponding to an image data sending portion that sends the image data for operation buttons stored in the memory portion 19 in correspondence with the array information to the TV 20, depending on the operation panel information acquired from the TV 20. When displaying the operation panel of the recorder 10, the TV 20 arranges and displays the image data for operation buttons sent from the recorder 10 at positions corresponding to the array information.
Then, when any image data for operation buttons is selectively specified by the user, the TV 20 sends the array information on the selectively specified image data to the recorder 10. The recorder 10 is provided with a data table that correlates the array information sent to the TV 20 with functions allocated respectively to the image data for operation buttons, and the recorder 10 is controlled to identify from the data table a function corresponding to the array information on the image data sent from the recorder 10, to execute the identified function. The data table is intended to be stored in the memory portion 19.
The operation panel information is intended to contain, specifically, in addition to the above array information, the display region size, the display position, the number of the display colors, and the display size of the image data for operation buttons, of the operation panel. The array information represents arrayable position and number of image data for operation buttons in the form of a matrix pattern of e.g., 3 columns (A, B, and C)×5 rows (1, 2, 3, 4, and 5), the number of image data arrayable being 15 in this case.
In the above, the image data for operation buttons include image data functioning as the operation buttons themselves and used as the real operation buttons, and image data used only for the representation such as operation guidance (operational explanation). The image data format may be any format as long as it can handle images of bitmap, JPEG (Joint Photographic Experts Group), etc.
The recorder 10 may send to the TV 20 attribute information together with image data of operation buttons and/or operation guidance and array information thereof (see
When the recorder 10 acquires 3 columns×5 rows as the array information from the TV 20, it allocates the image data for operation buttons, for example, image data of “power button” to column A, row 1, and image data of “play button” to column A, row 2, and sends the image data for operation buttons in correspondence with the array information to the TV 20. The recorder 10 stores the correspondence relationships (image data, array, and function) at that time as the data table in the memory portion 19. Then, the TV 20 arrays and displays the image data for operation buttons sent form the recorder 10 in compliance with the positions (hereinafter, also called coordinates) indicated by the array information.
Although the TV 20 can display the operation panel containing the image data for operation buttons of the recorder 10 in this manner, the TV 20 has merely to provide the display region of the operation panel and the recorder 10 determines which one of operation button image data is to be disposed at which position, whereupon as long as supporting the operation panel expansion display function according to the present invention, any peripherals can display the operation panel.
When one of the image data for operation buttons on the screen is selectively specified by the user acting on the remote control device R, the TV 20 has only to send the coordinate of the image data for the operation button, not the operation command of that operation button, to the recorder 10. Based on the coordinate sent from the TV 20, the recorder 10 can specify a corresponding function and execute the function. For example, if the coordinate is “column A, row 2 (A2)”, “play button” is allocated thereto allowing the recorder 10 to execute a play.
In this manner, according to the present invention, the operation panel can be customized and displayed on a peripheral-by-peripheral basis irrespective of whether the display device retains the operation panel, thereby achieving enhanced expandability in the operation of the peripherals.
Although the recorder 10 acquires the operation panel information from the TV 20 at this time, two methods are conceivable in the case of the HDMI connection, i.e., a first method of utilizing the EDID and a second method of utilizing a vendor command of the CEC message.
The Sink device (TV 20 in this case) in conformity with the HDMI standard has the EDID in its internal memory. The EDID is an ID proper to the TV for transmitting the TV model name and set values (resolution, etc.) to the Source device (recorder 10 in this case) connected to the TV, and an HDMI control signal line (12C) is used for the interchange of the EDID. For example, when the recorder 10 is connected to the TV 20 via the HDMI, the recorder 20 accesses the TV 20 to read the EDID so that it can output videos at a resolution adapted to the TV 20.
In the first method, the operation panel information is written in advance into the EDID. This allows the recorder 10 when accessing the TV 20 to read in and acquire the operation panel information contained in the EDID.
In the second method, the CEC message is sent together with the operation panel information added thereto from the TV 20 to the recorder 10. Available as the CEC message may there be e.g., the vendor command that the maker can define on its own terms.
At this time, the TV 20 performs a scaling of the input video signal, which will be described below, so as to prevent the display region of the input video signal from overlapping the display region of the operation panel of the recorder 10.
In the example of
For example, in the case where the user allows a display of the operation panel of the recorder 10 by the operation of the remote control device R during viewing a program on the TV 20, the video signal of the program is subjected to the scaling so that the video in the program does not overlap with the operation panel.
This prevents the video in the program from being hidden by the operation panel during watching, and the visual recognizability is not impaired.
The example of
As set forth hereinabove, the operation panel information is composed of five pieces of information, i.e., the display region size, the display position, and the number of display colors of the operation panel as well as the display size of the image data for operation buttons and array information (matrix pattern) indicating, in a matrix form, the arrayable position and number of image data for operation buttons, and in this example, those being set to 384×810, (1536, 270), 256 colors, 128×128, and 3 columns, 5 rows in the mentioned order. Then, this operation panel information is acquired by the recorder 10, by being sent to the recorder 10 from the TV 20 using the CEC message or by reading the EDID of the TV 20 by the recorder 10.
First, the TV 20 inquires of the recorder 10 a support level for determining whether it supports the operation panel expansion display function according to the present invention (S1), and the recorder 10 returns (notifies) its own support level to the TV 20 (S2). The recorder 10 retains in advance its own support level in the internal memory and retains “level 1” if not supported and “level 2” if supported.
Then, the TV 20 determines whether recorder 10 supports the operation panel expansion display function, based on the support level returned from the recorder 10 (S3). At that time, if the return from the recorder 10 is “level 2”, then the TV 20 determines that the recorder 10 is a supporting peripheral (case of YES) and sends the operation panel information to the recorder 10 (S4). If the return from the recorder 10 is “level 1” at S3, then the TV 20 determines it as being an unsupporting peripheral (case of NO) and displays an operation panel for the default of the recorder 10 that the TV 20 has (S5). In the absence of any return to the inquiry at S1, the TV 20 may determine the recorder 10 as being unsupporting.
The operation panel for the default (hereinafter, referred to as default operation panel) of the recorder 10 at S5 means an operation panel corresponding to the recorder 10 that the TV 20 has in advance, and it differs from the operation panel according to the present invention (hereinafter, it is often referred to as a custom operation panel). This default operation panel is intended, similar to the prior art, to allow the user to operate the remote control device R to send an operation command of an operation button selectively specified. In case that the peripheral connected to the TV 20 is an unsupporting peripheral and that the TV 20 has no default operation panel, the TV 20 desirably makes an error display, etc., since it cannot display the operation panel.
Although this example may use the vendor command of the CEC message for example for the communication between the TV 20 and the recorder 10, the communication means is not limited to the CEC.
The 2×2 array pattern depicted in
First, as set forth above referring to
Next, the recorder 10 performs optimization processing of the operation panel depending on the operation panel information sent from the TV 20 (S12). As first optimization processing, the recorder 10 determines whether among a plurality of different array patterns held by the recorder 10 there is one coinciding with the matrix pattern sent from the TV 20, and, if there is one coinciding therewith, selects the coinciding array pattern, and, if there is no one coinciding therewith, selects the maximum array pattern accommodated within the matrix pattern.
Since the matrix pattern from the TV 20 is 3×5 in this example, the array pattern of pos—3×5 is determined to coincide therewith among the plurality of array patterns stored in the recorder 10. In a case for example where the matrix pattern from the TV 20 is 2×5 without any array pattern coinciding therewith, the maximum array pattern accommodated within the 2×5 matrix pattern is determined to be 2×4. In this case, one row is blank.
It is determined as second optimization processing whether the image data for operation buttons coincide in display size. Here, a first display size of the image data for operation buttons held by the recorder 10 is 100×80 (
The recorder 10 may retain image data for operation buttons of a plurality of display sizes corresponding to the custom operation panel so that any one is selected from among these image data for operation buttons. If, for example, there exists image data for operation buttons coinciding with the second display size sent from the TV 20, the recorder 10 selects this image data for operation buttons, whereas if there exists no image data for operation buttons coinciding with the second display size, it selects image data for operation buttons smaller than the second display size. Then, similar to the above, if the display sizes do not coincide, the recorder 10 performs offset/resizing processing.
As depicted in
x=(Wt−Wr)/2=14,y=(Ht−Hr)/2=24
to consequently obtain the offset amount (x=14, y=24). Then, when sending the image data for operation buttons to the TV 20, the recorder 10 sends the obtained offset amount as the offset information thereto.
If the first display size retained by the recorder 10 does not coincide with the second display size sent from the TV 20, the recorder 10 may resize the image data of the first display size so as to fit the second display size. If, for example, the first display size of the recorder 10< the second display size of the TV 20 as described above, it may expand the image data of the first display size so as to be of the same size as the second display size. On the contrary, if the first display size of the recorder 10> the second display size of the TV 20, it may reduce the image data of the first display size to be of the same size as the second display size.
As depicted in
In
Since image data are sent in the processing of data sending from the recorder 10 to the TV 20, a more high-speed data sending becomes feasible by using the HDMI HEC line 43 higher in the communication speed than the HDMI CEC line 42.
Here, the TV 20 may store the image data for operation buttons sent from the recorder 10, together with the identification information of the recorder 10, in correspondence with the coordinate. In this case, at the time of next connection with the recorder 10, the TV 20 specifies image data for operation buttons stored in the TV 20, based on the identification information of the recorder 10, and disposes and displays the specified image data at a position corresponding to the coordinate. This eliminates the necessity of sending image data for operation buttons each time of power on/off or detachment/attachment of the HDMI cable, thereby reducing the communication load.
Use may be made of a part of a default operation panel held by the TV 20. In this case, the recorder 10 notifies the TV 20 of substituting, in accordance with the operation panel information sent from the TV 20, some of the operation buttons making up the operation panel of the recorder 10 with operation buttons of the default operation panel corresponding to the recorder 10 held by the TV 20. Then, the recorder 10 is configured to send to the TV 20 image data for the remaining operation buttons making up the operation panel of the recorder 10, in correspondence with the coordinate.
The TV 20 substitutes, based on the notice from the recorder 10, the some of the operation buttons making up the operation panel of the recorder 10 with the operation buttons of the default operation panel. Then, when the user acts on the remote control device R to selectively specify the substituted operation button, the TV 20 sends to the recorder 10 an operation command corresponding to the selectively specified operation button. That is, the operation command is sent for the operation buttons substituted by the default operation panel, whereas the coordinate is sent for the operation buttons of the custom operation panel. As a result, the recorder 10 need not send image data for all the operation buttons making up the operation panel, contributing to a reduction in the communication load.
The recorder 10 may retain in advance a plurality of image data that defer for each operation status for one operation button and send them to the TV 20. In this case, the TV 20 is configured to change over and display the plurality of image data of the operation button sent from the recorder 10, depending on the operation status of that operation button. The TV 20 changes over, for each operation button, the plurality of image data depending on the operation status of the recorder 10 such as for example valid, invalid (inoperable), selection, and determination. Specifically, the recorder 10 may notify the TV 20 of the operation status of the operation button, while in response to the notice, the TV may change over the plurality of image data depending on the operation status notified of.
For example, if the recorder 10 determines the stop button to be inoperable, then it notifies the TV 20 of the fact. When receiving the notice, the TV 20 changes over the image data of the stop button to image data indicative of being inoperable for the display. If the stop button in inoperable status is depressed and selectively specified, then control is provided such that the TV 20 does not send the coordinate of the stop button to the recorder 10. Alternatively, the TV 20 may gray out the stop button so that the button cannot be selected or may prohibit the cursor from moving to the position of the stop button so that the button cannot be selected.
Exemplary actions of the peripheral control system according to the present invention will now be described based on the screen transition of the TV 20 depicted in
First, the user turns on the power of the recorder 102 (S61) and thereafter acts on the remote control R to display a peripheral list 202 of peripherals connected to the TV 20 (S62). The peripheral list 202 carries names of peripherals being currently connected to the TV 20. The recorder 101, the recorder 102, the recorder 103, and the AV amplifier 50 correspond respectively to recorder 1, recorder 2, recorder 3, and AV amplifier. At that time, the display of the recorder 1 being off is grayed out.
In the peripheral list 202, most recently powered-on recorder 2 is recognized as an active peripheral and is displayed in an emphasized manner by a bold frame on the peripheral list 202 so that it can be distinguished from the other peripherals. By selecting the recorder 1 being power-off, the recorder 1 may be powered on and operated. In this case, the display of the recorder 1 is emphasized.
Then, when the user acts on the remote control device R to select a peripheral whose operation panel is desired to be displayed from the peripheral list 202, there appears the default operation panel 201 corresponding to the peripheral. In a display example of the default operation panel 201, it is displayed as depicted in

Then, when the user operates the remote control R to depress the play button, the TV 20 recognizes that the coordinate corresponding to the play button is B2 and notifies the recorder 10 of the depression of the coordinate B2 (S84). In response to this notice, the recorder 10 specifies a function (PLAY in this case) corresponding to the coordinate B2 and executes the play function (S85). In this manner, although the TV displays the operation buttons for operating the peripherals connected thereto, the TV need not grasp what functions the operation buttons have and has simply to send the coordinates of the operation buttons. For this reason, the load on the TV can be reduced to a large extent.
In this case, it is considered that the TV 20 determines in advance the array position and size of the information display region to be arrayed on the screen so as to impart thereto region identification information (for example, identification number 1, 2, . . . , etc.) for identifying the information display region. Then, the TV 20 retains the operation panel information containing the array position and the size of the information display region and the region identification information. When the operation panel information is sent from the TV 20 to the recorder 10, the recorder 10 determines a region to array the display information and sends the region identification information of this region together with the display information to the TV 20. The TV 20 displays the display information sent from the recorder 10 in the information display region corresponding to the region identification information.
