Description

  The present invention relates to an OSD signal processing apparatus that generates and outputs an OSD signal, an AV apparatus and a video display system including the OSD signal processing apparatus, and an OSD display method for displaying an OSD.

In recent years, various video display devices such as a television receiver (hereinafter referred to as a TV receiver) having an OSD (On Screen Display) function for displaying arbitrary characters and symbols on a display screen have been developed. The TV receiver has a built-in OSD signal processing device, and the OSD signal generated by the OSD signal processing device and the video signal input to the OSD signal processing device are switched and output to the display unit. Thus, the OSD is displayed on the display screen of the display unit.
In a TV receiver equipped with an OSD function, only a few numerical buttons such as an up / down button, a selection button, and an enter button are provided on the TV receiver main body, and the buttons corresponding to the OSD appearing on the display screen are operated. Make various settings and adjustments. As a result, the number of parts of the TV receiver can be reduced and the cost can be reduced, and since the setting is made on the large screen of the TV receiver, complicated operations such as input frequency and color temperature adjustment can be performed.

When an AV device including a recording / playback device such as an HDD (Hard Disk Drive), a DVD (Digital Versatile Disc) recorder, or a BD (Blu-ray Disc) recorder is connected to the TV receiver, recording reservation of the AV device is performed. , And various settings can also be made based on the OSD. The AV device incorporates an OSD signal processing device, and the OSD signal generated by the OSD signal processing device is superimposed on the video signal input to the OSD signal processing device and output to the display unit of the TV receiver. Thus, an image based on the OSD is displayed on the display screen of the display unit.
However, when a plurality of playback devices, recording devices, recording / playback devices, etc. are connected to the TV receiver, the OSD generated by the TV receiver and the image including the OSD of the playback device overlap, making it difficult to see. Sometimes.

FIG. 13 is an explanatory diagram showing a display screen of the display unit 82 of the TV receiver to which a conventional recording / playback apparatus is connected.
On the display screen, a video 820 reproduced by the recording / reproducing apparatus is displayed. An image 821 based on the OSD generated by the recording / reproducing apparatus is displayed on the video 820, and the image 821 is mostly overlapped with the image 821. An OSD 822 generated by the TV receiver is displayed. In this case, most of the “program content” of the image 821 is hidden under the OSD 822 and is not visible.

  When the warning by the OSD of the TV receiver and the warning by the image based on the OSD from the recording / playback apparatus are displayed at the same time, there is a problem that the warning by any device is not known.

In addition, in a multi-function device in which a TV receiver and a recording / playback device are integrated, such as a DVD built-in TV receiver and a BD recorder built-in TV receiver, the TV receiver main body and the recording / playback device are operated by respective control units. It is often configured as a so-called add-on type that is controlled. Furthermore, in order to efficiently supply products not only to multifunction peripherals but also to other areas with different specifications such as broadcasting system and additional functions, for example, an analog tuner unit is incorporated in the main board of a TV receiver, In some different regions, tuner units including digital tuners may be produced by adding them as add-ons on separate boards and supplied to the entire world. In this case, as in the case of the recording / reproducing apparatus, the tuner unit outputs an OSD signal independently.
In the case of these add-on types, the add-on recording / playback device and tuner unit (hereinafter referred to as add-on unit) may be manufactured by a company different from the TV receiver, and the OSD of the TV receiver main body and the OSD of the add-on unit are installed. There is a problem that the image including the image may be displayed in a state where both of the images are superimposed on the upper right of the display screen. In this case, the add-on unit may not be operated or an incorrect operation may be performed.

  In order to solve the above-described problem, there is a conventional method in which the OSD color is set for each AV device such as a TV receiver, a recording / playback device, and the like. However, with this method, the user must set a color for each TV receiver and AV device in advance. In addition, there is a method of displaying “TV”, “Recorder”, etc. in an EPG (Electronic Program Guide), but “TV”, “Recorder”, etc. are displayed only on an image based on a specific OSD, and “ There is a problem that unnecessary information such as “TV” is displayed, and when a plurality of AV devices of the same type are connected, it is not possible to distinguish which OS device is based on which AV device.

In the present embodiment, the OSD (1) and the OSD (2) are displayed so as not to overlap each other by the OSD display method described later.
The speaker 21 reproduces sound based on the given sound signal.

The OSD display method (OSD position / color information setting process) according to the embodiment of the present invention will be described in detail below.
3 and 4 are flowcharts showing a processing procedure of the control unit 7 of the TV receiver 2, a processing procedure of the control unit 36 of the first recorder 3, and a processing procedure of the control unit of the second recorder 4. 5 and 6 are explanatory diagrams showing communication between the TV receiver 2 and the first recorder 3 and the second recorder 4 and display contents of the display unit 22. Hereinafter, as an example, when a video is being reproduced from a recording medium attached to the first recorder 3, the OSD (1) is displayed from the TV receiver 2, and the OSD (2) is further displayed from the first recorder 3. Explain when.

The control unit 7 determines whether or not the video reproduced by the first recorder 3 is being displayed (S1). If it is determined that the video is not being displayed (S1: NO), this determination is repeated.
When it is determined that the video is being displayed (S1: YES), the control unit 7 determines whether display of OSD (1) is requested (S2). For example, the control unit 7 determines whether or not an OSD (1) display instruction is given by an operation of the user's remote control 10. When it is determined that the display of OSD (1) is not requested (S2: NO), the control unit 7 repeats this determination.

When the control unit 7 determines that the display of the OSD (1) is requested (S2: YES), the control unit 7 reads the information of the OSD (1) from the storage unit 11 and outputs the information to the OSD signal generation unit 12. The OSD signal generation unit 12 generates an OSD signal based on the input information and outputs it to the synthesis unit 13.
The synthesizer 13 switches between the recorder video signal input from the video processor 20 and the OSD signal and outputs the signal to the display unit 22. Thus, OSD (1) is displayed (S3). FIG. 5A shows a state in which a video 220 is displayed on the display unit 22 and an OSD (1) image 221 is displayed at a substantially central portion of the video 220.

  Next, the control unit 7 reads the position / color information of the OSD (1) from the storage unit 11, and the read position / color information is read via the HDMI communication unit 5 as shown in FIG. The data is transmitted to the first recorder 3 and the second recorder 4 (S4).

  The control unit 36 of the first recorder 3 records the received position / color information of the OSD (1) in the storage unit 40 (S21). Similarly, the control unit of the second recorder 4 records the position / color information of the OSD (1) received in the storage unit in the storage unit (S41).

  The control unit 36 of the first recorder 3 determines whether or not display of the OSD (2) is requested (S22). As an example of the OSD (2) display request, there is an instruction to display the contents of the recorded video by the user.

The control unit 36 reads the first position information and the first color information from the information of the OSD (2) from the storage unit 40. Then, it is determined whether OSD (1) and OSD (2) overlap and whether the colors of OSD (1) and OSD (2) match or approximate (S23).
As described above, the storage unit 11 stores the coordinate values (x ₁ , y ₁ ), (x ₂ , y ₁ ), (x ₁ , y ₂ ) of the four corners of the OSD (1) as the position information of the OSD (1). ) And (x ₂ , y ₂ ) are recorded, and (x ₃ , y ₃ ), (x ₄ , y ₃ ), (x ₃ , y ₄ ), and the first position information of the OSD (2) (X ₄ , y ₄ ) is recorded. In order, the coordinates of the upper left corner, the upper right corner, the lower left corner, and the lower right corner of the rectangle are shown. Based on these coordinates, it is determined whether or not there is a portion where the position of OSD (1) and the position of OSD (2) overlap.

When the control unit 36 determines that there is an overlapping part (S23: YES), the OSD (2) first position information is translated so that the coordinates of the OSD (2) do not overlap with the OSD (1). To the position information represented by the coordinates (x ₅ , y ₅ ), (x ₆ , y ₅ ), (x ₅ , y ₆ ), (x ₆ , y ₆ ).
The control unit 36 also has coordinates (x ₇ , y ₇ ), (x ₈ , y ₇ ), (x ₇ , y) when the size of OSD (2) is reduced so as not to overlap with OSD (1). ₈ ) and (x ₈ , y ₈ ) may be used to change the position information. Furthermore, the OSD (2) may be reduced by reducing the font of the OSD (2).

Furthermore, the control unit 36 determines whether or not the colors of OSD (1) and OSD (2) match or approximate. Here, both “colors match” means that the luminance values of each RGB match, and both “colors approximate” means that the difference between the luminance values of both RGB is a predetermined value. It is within range.
When it is determined that the two colors match or approximate, the control unit 23 changes the first color information to color information relating to a color different from the OSD (1). Specifically, the RGB luminance values are changed to change the colors. When it is determined that the two colors are not approximate, the color is maintained.
Even when OSD (1) and OSD (2) do not overlap, the control unit 36 changes the color of OSD (2) when the colors of OSD (1) and OSD (2) match or approximate.
As described above, when OSD (1) and OSD (2) overlap, the control unit 36 changes the position information of OSD (2), and the color matches or approximates the color of OSD (1). The color information is changed, and the changed position information and color information are set as the setting information (S24).

When the control unit 36 determines that the OSD (1) and the OSD (2) do not overlap and the colors do not match or approximate (S23: NO), the first position information and the first color information of the OSD (2). Is determined as setting information (S25).
Then, the control unit 36 causes the OSD signal synthesis unit 41 to generate an OSD (2) signal based on the set position information, color information, and other information of the OSD image (S26).

  The control unit 36 displays the generated OSD (2) (S27). The control unit 36 outputs the generated OSD (2) signal to the synthesizing unit 42, and the synthesizing unit 42 synthesizes and obtains the recorder video signal input from the video processing unit 34 and the OSD (2) signal. The synthesized video signal is output to the HDMI communication unit 35. In the TV receiver 2, the composite video signal input from the HDMI communication unit 5 is output to the synthesis unit 13 via the signal control unit 18 and the video processing unit 20. In the synthesizing unit 13, the synthesized video signal and the OSD (1) signal are switched and output to the display unit 22 to display OSD (2).

The control unit 36 transmits the position / color information of the OSD (2) to the control unit 7 by the CEC message (S28).
In FIG. 5C, the OSD (1) image 221 and the OSD (2) image 222 are separated from each other on the display screen of the display unit 22 and displayed in different colors. A state in which the OSD (2) position / color information is transmitted to the receiver 2 is shown. Since OSD (1) and OSD (2) are separated, OSD (1) and OSD (2) are visually recognized well.

The control unit 7 records the position / color information of the OSD (2) in the storage unit 11 (S5). Then, as shown in FIG. 6D, the position / color information of the OSD (2) is transmitted to the second recorder 4 by the CEC message (S6).
The control unit of the second recorder 4 records the position / color information of the OSD (2) in the storage unit (S42).

Next, the control unit 7 determines whether or not the OSD (1) can be erased (S7). Examples of the case where the OSD (1) can be erased include a case where a predetermined time has elapsed after the display of the OSD (1) is started, and a case where the user gives an erase instruction by operating the remote controller 10. When it is determined that the OSD (1) cannot be deleted (S7: NO), the control unit 7 repeats this determination.
When it is determined that the OSD (1) can be deleted (S7: YES), the control unit 7 stops outputting the signal of the OSD (1) to the synthesis unit 13 and displays the OSD (1). Is deleted (S8). And the information that OSD (1) was deleted is transmitted to the control part 36 and the control part of the 2nd recorder 4 by a CEC message (S9). In FIG. 6E, OSD (1) is deleted from the display screen of the display unit 22, and information that the OSD (1) is deleted from the TV receiver 2 to the first recorder 3 and the second recorder 4 is transmitted. Indicates the state.
After receiving the information, the control unit 36 erases the position / color information of the OSD (1) from the storage unit 40 (S29), and the control unit of the second recorder 4 stores the position / color information of the OSD (1). Is deleted from the copy (S43).

Next, the control unit 36 determines whether or not the OSD (2) can be erased (S30). As an example in which OSD (2) can be erased, there is a case where a predetermined time has elapsed after the display of OSD (2) is started. When it is determined that the OSD (2) cannot be deleted (S30: NO), the control unit 36 repeats this determination.
When it is determined that the OSD (2) can be erased (S30: YES), the control unit 36 stops outputting the signal of the OSD (2) to the synthesis unit 42 and displays the OSD (2). Is deleted (S31), and information indicating that the OSD (2) has been deleted by the CEC message is transmitted to the control unit 7 (S32).

The control unit 7 receives the information, deletes the position / color information of the OSD (2) from the storage unit 11 (S10), and information that the OSD (2) has been deleted as shown in FIG. Is transmitted to the second recorder 4 (S11).
The control unit of the second recorder 4 that has received the information deletes the position / color information of the OSD (2) from the storage unit (S44).

And the control part 7 determines whether the display of an image | video was complete | finished (S12). If it is determined that the video display has not ended (S12: NO), the process returns to step S2.
When it is determined that the video display has ended (S12: YES), the control unit 7 ends the OSD position / color information setting process.

According to the present embodiment, the OSD (2) is generated on the display screen of the display unit 22 so that the OSD (2) does not overlap with the OSD (1). Therefore, as shown in FIG. (1) and OSD (2) are visually recognized well.

The OSD display method (OSD position / color information setting method) according to the present embodiment will be described in detail below.
11 and 12 are flowcharts showing the processing procedure of the control unit 57 of the TV receiver 52 and the processing procedure of the control unit 66 of the BD recorder unit 60. Hereinafter, as an example, when video is played back from a recording medium attached to the BD recorder unit 60, OSD (1) is displayed from the control unit 57, and OSD (2) is further displayed from the control unit 66. explain.

The control unit 57 determines whether or not the video reproduced by the BD recorder unit 60 is being displayed (S51). If it is determined that the video is not being displayed (S51: NO), this determination is repeated.
When it is determined that the video is being displayed (S51: YES), the controller 57 determines whether or not display of OSD (1) is requested (S52). The control unit 57 determines whether or not there is an OSD (1) display instruction or the like, for example, by an operation of the user's remote control 10. When it is determined that the display of OSD (1) is not requested (S52: NO), the control unit 57 repeats this determination.

When the control unit 57 determines that the display of the OSD (1) is requested (S52: YES), the control unit 57 reads the information of the OSD (1) from the first storage unit 51 and outputs the information to the OSD signal generation unit 12. The OSD signal generation unit 12 generates an OSD signal based on the input information and outputs it to the synthesis unit 13.
The synthesizer 13 switches between the recorder video signal input from the video processor 20 and the OSD signal and outputs the signal to the display unit 22. Thus, OSD (1) is displayed (S53).

  Next, the control unit 57 reads the position / color information of the OSD (1) from the first storage unit 51, and transmits the read position / color information to the control unit 66 of the BD recorder unit 60 (S54).

  The control unit 66 of the BD recorder unit 60 records the received OSD (1) position / color information in the second storage unit 61 (S71).

  The control unit 66 of the BD recorder unit 60 determines whether or not the display of the OSD (2) is requested (S72). As an example of the OSD (2) display request, there is an instruction to display the contents of the recorded video by the user.

The control unit 66 reads the first position information and the first color information from the image information of the OSD (2) from the second storage unit 40. Then, it is determined whether OSD (1) and OSD (2) overlap and whether the colors of OSD (1) and OSD (2) match or approximate (S73).
The second storage unit 61 stores the coordinate values (x ₁ , y ₁ ), (x ₂ , y ₁ ), (x ₁ , y ₂ ) of the four corners of the OSD (1) as the first position information of the OSD (1). ) And (x ₂ , y ₂ ) are recorded, and (x ₃ , y ₃ ), (x ₄ , y ₃ ), (x ₃ , y ₄ ), and the first position information of the OSD (2) (X ₄ , y ₄ ) is recorded. The coordinates of the upper left corner, upper right corner, lower left corner, and lower right corner of the rectangle are shown in order. Based on these coordinates, it is determined whether or not there is a portion where the position of OSD (1) and the position of OSD (2) overlap.

If the controller 66 determines that there is an overlapping portion (S73: YES), the first position information is translated (x ₅ , y) so that the coordinates of the OSD (2) do not overlap with the OSD (1). ₅ ), (x ₆ , y ₅ ), (x ₅ , y ₆ ), and (x ₆ , y ₆ ).
The controller 66 also coordinates (x ₇ , y ₇ ), (x ₈ , y ₇ ), (x ₇ , y) when the size of OSD (2) is reduced so as not to overlap with OSD (1). ₈ ) and (x ₈ , y ₈ ) may be used to change the position information.

Further, the control unit 66 determines whether or not the colors of OSD (1) and OSD (2) match or approximate. When it is determined that the two colors match or approximate, the control unit 66 changes the first color information of the OSD (2) to color information relating to a color different from the OSD (1). Specifically, the RGB luminance values are changed to change the colors.
Even when OSD (1) and OSD (2) do not overlap, the control unit 66 changes the color of OSD (2) when the colors of OSD (1) and OSD (2) match or approximate.
As described above, the control unit 36 changes the position information of the OSD (2) when the OSD (1) and the OSD (2) overlap, and the color matches or approximates the color of the OSD (1). The color information is changed, and the changed position information and color information are set as setting information (S74).

When it is determined that the OSD (1) and the OSD (2) do not overlap and the colors do not match or approximate (S73: NO), the control unit 66 determines the first position information and the first color of the OSD (2). Information is determined as setting information (S75).
Then, the control unit 66 causes the OSD signal synthesis unit 41 to generate a signal of OSD (2) based on the set position information and color information and other image information of OSD (2) (S76).

The control unit 66 displays the generated OSD (2) (S77). The control unit 66 outputs the generated OSD (2) signal to the synthesizing unit 42, and the synthesizing unit 42 synthesizes the input recorder video signal and the OSD (2) signal, and obtains the synthesized video signal obtained. Is output to the signal controller 58.
The synthesized video signal is output to the synthesis unit 13 via the video processing unit 20. In the synthesizing unit 13, the synthesized video signal and the OSD (1) signal are switched and output to the display unit 22 to display OSD (2).

The control unit 66 transmits the position / color information of the OSD (2) to the control unit 57 (S78).
The control unit 57 records the position / color information of the OSD (2) in the first storage unit 51 (S55).

Next, the control unit 57 determines whether or not the OSD (1) can be erased (S56). Examples of the case where the OSD (1) can be erased include a case where a predetermined time has elapsed after the display of the OSD (1) is started, and a case where the user gives an erase instruction by operating the remote controller 10. When it is determined that the OSD (1) cannot be deleted (S56: NO), the control unit 57 repeats this determination.
When it is determined that the OSD (1) can be erased (S56: YES), the control unit 57 stops outputting the signal of the OSD (1) to the synthesis unit 12, and displays the OSD (1). Is deleted (S57), and information indicating that OSD (1) has been deleted is transmitted to the controller 66 (S58).

  After receiving the information, the control unit 66 deletes the position / color information of the OSD (1) from the second storage unit 61 (S79).

Next, the control unit 66 determines whether or not the OSD (2) can be erased (S80). As an example in which OSD (2) can be erased, there is a case where a predetermined time has elapsed after the display of OSD (2) is started. When it is determined that the OSD (2) cannot be deleted (S80: NO), the control unit 66 repeats this determination.
When it is determined that the OSD (2) can be deleted (S80: YES), the control unit 66 stops outputting the signal of the OSD (2) to the combining unit 42, and displays the OSD (2). Is deleted (S81), and information indicating that OSD (2) has been deleted is transmitted to the control unit 57 (S82).

  The control unit 57 receives the information and deletes the position / color information of the OSD (2) from the first storage unit 51 (S59).

The control unit 57 determines whether or not the video display is finished (S60). If it is determined that the video display has not ended (S60: NO), the process returns to step S52.
If the control unit 7 determines that the video display has ended (S60: YES), the control unit 7 ends the OSD position / color information setting process.

According to the present embodiment, the OSD (2) is generated so that the OSD (2) does not overlap with the OSD (1) on the display screen of the display unit 22, so that the OSD (1) and the OSD (2) are good. Visible to.
