  1) Japanese broadcasting uses a so-called “overscan” method for screen display in order to maintain compatibility with conventional televisions, so dot display (according to the resolution of the input signal) Display with the number of panel pixels (also referred to as dot-by-dot display). On a type-type television, the screen display may not be displayed normally because it extends beyond the screen area. Therefore, video noise that has not been seen outside the screen area in the past (a management signal or control signal other than a display image that appears as image noise) may appear. In particular, when HD (full spec high-definition) broadcasts are displayed dot-by-dot as they are, the above-mentioned video noise may inevitably appear on the top and bottom or left and right edges of the screen. Display quality may deteriorate.

  2) In recent years, Blu-ray disc recorders (BD devices) that can directly record HD broadcasts with the same image quality have become widespread, but as described above, images recorded by actual broadcasts such as HD broadcasts with BD devices or DVD devices. Similarly, video noise may be seen at the top and bottom or left and right edges of the screen, and the display quality of high-quality HD images may deteriorate.

  Needless to say, the recording and / or reproducing device and the image display device may be configured as separate devices, and the recording and / or reproducing device 20 shown in FIG. It can be changed. For example, a function of separating the medium information in the information separating unit 24 of the recording and / or reproducing device 20 may be provided on the image display device side, for example, the image display method selecting unit 30. In this case, it is obvious that even a general recording and / or reproducing apparatus functions in the same manner as the embodiment shown in FIG. 1 as long as it is of a type that outputs information about a medium.

  In addition, when the recording and / or reproducing apparatus and the image display apparatus are configured as separate apparatuses, the “recording and / or reproducing apparatus” and the “image display apparatus” are detachably connected. It is good also as a structure separable (detachable) by a means. For example, an SPDIF terminal is used as a connection terminal for digital audio signals, an HDMI terminal is used as a connection terminal for video signals and medium information, and a power supply terminal is provided to supply power from the image display apparatus side. The medium information uses a CEC signal in the HDMI terminal. Each of the “recording and / or reproducing device” and the “image display device” is provided with the above-described terminals so as to be mechanically detachable. Although it is good also as a structure which connects each terminal directly, it is good also as attachment or detachment through the connecting wire which connects mutually.

  According to this, it becomes possible to easily cope with the case where it is necessary to change the specifications of the image display device and the recording and / or reproducing device or to replace the device. Further, by adopting a standard interface such as an HDMI terminal or an SPDIF terminal, the recording and / or reproducing apparatus can be set to a standard specification. Details will be described later with reference to FIG.

  In FIG. 1, reference numeral 1 denotes a CPU for controlling the image display system, which has a memory 2 in which a control program and the like are stored, a remote control light receiving unit 3 for receiving input from a user, and the like. 4 to each other. In particular, although not shown, a control signal 6 is supplied to each part of the image display system via the bus line 4. Reference numeral 5 denotes a remote controller as an input device for the CPU. Since these portions do not form the main part of the present invention, detailed description is omitted in the drawings. Detailed descriptions of these parts are omitted.

  Reference numeral 10 denotes a front-end unit of a television receiver having an analog and digital TV tuner 11 and a demodulating unit 12, and an audio signal from the front-end unit 10 passes through an audio selection unit 13 and an audio signal processing unit 14. The video signal is supplied to the speaker 15, and the video signal from the front end unit 10 is supplied to the display unit 18 via the video selection unit 16 and the display control unit 17. Since these portions also do not form the main part of the present invention, detailed description is omitted in the drawings. Detailed descriptions of these parts are omitted.

  Reference numeral 20 denotes a recording and / or reproducing apparatus using various recording media such as a hard disk (HDD) 25, a disk 26 such as a BD or a DVD / CD, a semiconductor memory 27, and the like. , An information reading unit 23, an information separation unit 24, and the like. Since the recording unit 21 is not a main part of the present invention, only the fact that the input signal line 28 is connected to the recording unit 21 is shown, and other details are omitted. Reference numeral 30 denotes an image display method selection unit, which includes a control signal generation unit 31 and a video signal processing unit 32.

  In the image display system having such a configuration, a specific disk such as a BD video (commercially available BD-ROM disc), a DVD video (commercially available DVD-ROM disc), a CD video ( When a commercially available CD-ROM disc) is inserted, the reproducing unit 22 starts reproducing each disc, and the information reading unit 23 reads information from the reproduced signal. In Blu-ray Disc (BD), the BDMV standard for storing image information contents such as movies is standardized in an application format. Similarly, in DVD, the DVD-Video format is standardized as one of the application formats, Each is recorded in a desired application format. Therefore, the information separation unit 24 separates information on these application formats (hereinafter referred to as medium information) and sends it to the control signal generation unit 31 of the image display method selection unit 30.

  The control signal generation unit 31 of the image display method selection unit 30 receives the medium information, and confirms that the signal from the recording and / or playback device 20 is a signal from a BD video (commercially available BD-ROM). A control signal that identifies and indicates that fact is sent to the video signal processing unit 32.

  The video signal processing unit 32 is provided with a processing unit that processes video signals with various display methods, and further includes a processing unit for displaying with various screen sizes. Also, an optimum display method for each recording medium is determined in advance, and a correspondence table (optimum display method correspondence table) indicating the optimum display method for the specific recording medium and the recording medium is stored in the video signal processing unit 32. Keep it. Therefore, by rewriting this correspondence table (optimum display method correspondence table), the optimum display method for a specific recording medium can be changed. When changing the optimum display method correspondence table, it is preferable that the optimum display method correspondence table itself is displayed on-screen so that the user can easily set it while viewing the screen display. Also, a plurality of correspondence tables (optimum display method correspondence tables) are prepared, and one can be used as a default set by the manufacturer, and the remaining one can be used by a plurality of users. You can also keep it. Various display methods and screen sizes will be described later with reference to FIG.

  When the video signal processing unit 32 receives a signal from the control signal generation unit 31, the video signal processing unit 32 refers to the correspondence table (optimum display method correspondence table) and is optimal for reproducing a BD video (commercially available BD-ROM). The video signal is processed by selecting the display method and sent to the video selection unit 16. When a recording and / or playback device is selected by input from the remote controller 5, the video selection unit 16 sends the video signal from the video signal processing unit 32 to the display unit 18 via the display control unit 17. In the display unit, an image is displayed by a display method optimum for reproducing BD video (commercially available BD-ROM). At the same time, the audio selection unit 13 also selects audio from the recording and / or playback device 20, sends it to the audio signal processing unit 14, and outputs it from the speaker 15.

  Specifically, for example, when the display panel of the display device has a resolution of 1920 × 1080, the video signal processing unit 32 receives “BD video (commercially available BD-ROM) from the control signal generation unit 31. ) ”, And with reference to the correspondence table (optimum display method correspondence table), an overscan rate of 100 in a dot-by-dot display method, which is a predetermined display method. % Display method "is selected, the video signal is processed and sent to the display unit 18 side. Thus, simply by inserting a BD video (commercially available BD-ROM) into the recording and / or playback device 20, the video signal recorded as a 1920 × 1080 full high-definition video is displayed on the display unit 18. Thus, it is possible to view a high-quality image having the same resolution as that of the input signal.

  When a different disc, for example, a DVD-RW (Video format) disc, is inserted into the recording and / or reproducing device 20, the information separating unit 24 of the recording and / or reproducing device 20 determines "DVD-RW (Video format). ) Is separated and sent to the control signal generator 31. The control signal generator 31 receives the medium information, identifies that the signal from the recording and / or reproducing device 20 is a signal from a DVD-RW (Video format) disc, and notifies that effect. The control signal shown is sent to the video signal processing unit 32.

  When the video signal processing unit 32 receives a signal from the control signal generating unit 31, the video signal processing unit 32 refers to the correspondence table (optimum display method correspondence table) and displays the optimum display for reproducing a DVD-RW (Video format) disc. The video signal is processed by selecting a method and sent to the video selection unit 16. When a recording and / or playback device is selected by input from the remote controller 5, the video selection unit 16 sends the video signal from the video signal processing unit 32 to the display unit 18 via the display control unit 17. On the display unit, an image is displayed in a display method optimum for reproducing a DVD-RW (Video format) disc. At the same time, the audio selection unit 13 also selects the audio from the recording and / or playback device 20, sends it to the audio signal processing unit 14, and outputs it from the speaker 15.

  Specifically, the display is performed with a display method in which the screen size is full size and the overscan rate is about 95%. This is because when a DVD-RW (Video format) disc is displayed with a dot-by-dot display method with an overscan rate of 100%, a so-called “video noise” noise component is displayed on the periphery of the screen. It is because it may be done.

  Depending on the type of disc and the performance of the display unit, the optimal display method is determined in advance so that the user can enjoy various discs with the best display method without having to perform special settings. be able to.

  The display method includes a dot-by-dot display method, a screen size full display method with an overscan rate of 100% or less, for example, 95%, and how the screen size is set. This point will be described in detail with reference to FIG.

  FIG. 2 is a diagram showing an example for explaining the situation described above. In FIG. 2, when a disc is inserted into the recording and / or playback device 20 while an image receiving screen from the TV tuner side as shown in the display screen 18-1 is displayed, the display screen 18-2 shows. Thus, for example, a display indicating that the disk is being read is displayed in the OSD display near the lower right of the screen, and it is displayed that the disk is being read.

  Case [A] (shown in the upper part) shows a case where a BD video (commercially available BD-ROM) is inserted into the recording and / or playback device 20. When the input is switched from the TV tuner side to the recording and / or playback device 20 side, as shown in the display screen 18-3, a display with an overscan rate of 100% is performed by a dot-by-dot display method. Become.

  In the case [B], a case where a DVD-RW (Video format) disc is inserted into the recording and / or reproducing apparatus 20 is shown. When the input is switched from the TV tuner side to the recording and / or playback apparatus 20 side, as shown in the display screen 18-4, display is performed with a full screen size and an overscan rate of 95%.

  FIG. 3 is a diagram for explaining various display types that can be selected for various input signals. In FIG. 3, the display unit is assumed to be a display device having a resolution of 1920 × 1080. The case where the input signal is a video with a screen aspect ratio of 4: 3 and the case where the input signal is a video signal with a screen aspect ratio of 16: 9 are considered separately.

  First, consider the case where the input signal has a screen aspect ratio of 4: 3. In this case, for example, the signal has a resolution of 1280 × 1024, 1024 × 768, 800 × 600, and 640 × 480. When there is an input signal of this resolution, in a display device having a resolution of 1920 × 1080, as a screen size, normal mode display, cinema mode display, full mode display, dot-by-dot mode The display with can be considered.

  The display in the normal mode is the one that reflects the aspect ratio of the input signal without losing the aspect ratio, and the display in the cinema mode is the one that expands to the left and right of the screen without losing the aspect ratio of the input signal. In this mode, the aspect ratio of the input signal is lost, but the video signal is projected to fill the screen. In the dot-by-dot mode, the display is performed with the number of panel pixels according to the resolution of the input signal. For example, when a signal having a resolution of 1280 × 1024, 1024 × 768, 800 × 600, and 640 × 480 is input to a display device having a display panel arithmetic resolution of 1920 × 1080, generally, As shown, the display is such that an area that is not displayed in the periphery is formed.

  In the present invention, an optimal display method is determined in advance for each input signal having a resolution of 1280 × 1024, 1024 × 768, 800 × 600, and 640 × 480, and a disk of each input signal is recorded and / or recorded. When inserted into the playback device 20, the image display method selection unit 30 selects a predetermined optimum display method. If the medium information does not include information on the resolution of the input signal, information on the screen size, etc., the resolution may be obtained by analyzing the input signal. For example, the determination can be easily made by identifying and calculating the black level region when the input signal is developed in the image memory for display.

  When the input signal has a screen aspect ratio of 16: 9, for example, when the input signal is a signal having a resolution of 1360 × 768 and 1920 × 1080, as in the case where the input signal is 4: 3, normal and full A dot-by-dot display method can be considered. The reason why “Cinema” is blank is that the result is the same display method as “Full”. Needless to say, if it is necessary to cope with a new input signal such as 21: 9, a display method provided for it may be considered. In the dot-by-dot column, an area where no image is displayed in the periphery is shown. The display unit 18 is a display device having a resolution of 1920 × 1080, and the input signal has a resolution of 1920 × 1080. If it is a signal, the image is displayed in full screen.

  Also in this case, the optimum display method is determined in advance for each input signal, and the image display method selection unit 30 when the disc of each input signal is inserted into the recording and / or reproducing device 20. The optimum display method determined in advance is selected.

  FIG. 4 is a flowchart showing an example of the operation of the image display system described above. This flowchart shows an example of selecting whether to display in “dot-by-dot display method” or “screen full display method with an overscan rate of 95%”. In this case, the dot-by-dot display method is selected.

  When a disc is inserted into the recording and / or reproducing apparatus 20 (step 1; hereinafter referred to as S1), the disc is detected by the reproducing unit 22 (S2), and information on the disc inserted by the information reading unit 23 is stored. The medium information (information relating to the format of the disk) is read (S3) and separated and sent to the image display method selection unit 30.

  The control signal generation unit 31 of the image display method selection unit 30 identifies the type of the inserted disc from the format-related signal (medium information) (S4). When the input is switched from the television side to the recording / reproducing unit 20 side (S5), the video signal processing unit 32 receives a signal from the control signal generating unit 31, determines whether the input is a BD input and a cell-type disc, and "YES" In the case of, the dot-by-dot display method is selected, and in the case of “NO”, the “screen full display method with an overscan rate of 95%” is selected.

Among the currently available disks, the following disks are preferable to adopt the dot-by-dot display method.
1. BD video (commercially available BD-ROM)
2. DVD video (including commercial DVD, finalized video format)
3. CD (CDDA) cell-based media In addition, it is preferable to use the “full screen with an overscan rate of about 95%” display method, or at least not to use the dot-by-dot display method. There are the following discs. The reason why the overscan rate is about 95% is that, for example, on a disc or the like on which an actual broadcast is recorded, there is a possibility that video noise may be seen in the periphery of the screen due to variations in recording equipment and format type. .
1. Unknown disk BD-RE (single layer / double layer)
3. BD-R (single layer / double layer)
4). DVD-RW (for photo)
5). DVD-RW (Video format)
6). DVD-RW (VR format)
7). DVD-RW (non-Video / VR format)
8). DVD-R (Video format)
9. DVD-R (VR format)
10. DVD-R (non-Video / VR format)
11. DVD-RAM
12 CD-RW
13. CD-R
In the above description, the image display method selection unit 30 predetermines a display method for a specific recording medium, for example, a disc type. However, depending on the user's preference, for example, the service of the manufacturer The setting can be changed by the user, or the user can change the setting by an input from the remote controller. The change can be made by rewriting the correspondence table (optimum display method correspondence table). Although the change remains a little annoying, once the setting is changed, an operation every time the disc is inserted and the image is reproduced becomes unnecessary, and the usability of the image display system can be improved.

  In addition, for example, when medium information from a recording medium indicates information recorded in the long-time mode, dot-by-dot display is selected as the display method, and image quality correction (enhancement enhancement) may be further performed. It is effective in improving image quality. The image quality correction is a function normally provided in a television and can be easily realized. Even in this case, when the video signal (character signal) from the recording and / or reproducing apparatus is displayed on the display screen, the image quality correction is not performed so that the character is not emphasized more than necessary. Is preferred.

  In addition, for users who do not need “a function to set the optimal display method for a specific medium in advance”, this function can be removed by the user's own setting or the setting by the manufacturer's service. You may keep it. Conversely, means for forcibly switching to dot-by-dot display, for example, by the user may be provided.

  Furthermore, in the above description, the optimum display method is set in advance depending on the type of recording medium, for example, a disc. However, the optimum display method may be selected depending on the type of recorded information. For example, an optimal display method may be set according to sports, movies, news, games, still images, and the like. In particular, in the case of still images, the display quality is greatly reduced if image noise appears in the surrounding area, so when displaying still images, if they are not displayed on the entire screen depending on the dot-by-dot display, The highest priority is given to full screen display. In addition, when changing the display method according to the content, it is desirable to give priority to what is given priority.

  In this case, it is necessary to further include information related to the content in the medium information, but whether or not the image is a still image can be easily determined by looking at the degree of change in the application format information and the image signal within a certain time. Therefore, this determination unit can be realized by providing the recording / reproducing unit 20. Whether it is a sport, a movie, a game, or the like is similarly determined by analyzing application format information and information on a title such as a disc. Also in this case, it is necessary to provide an analysis unit for the title and the like in the recording / reproducing unit 20.

  In the case where the recording and / or reproducing device is built in and integrated with the image display device, and further the recording medium itself is built in, for example, the HDD recording and / or reproducing device seems to be built in. In such a case, the information reproduced from the HDD is analyzed, and an optimal display method is selected according to the analysis result.

  FIG. 6 is a diagram schematically showing an outline of connection when the recording / reproducing apparatus and the image display apparatus are separately configured. Although it is the same structure as FIG. 1, only a connection part differs. In FIG. 6, reference numeral 20 denotes a recording and / or reproducing apparatus configured as a single unit, and reference numeral 60 denotes an image display apparatus configured as a single unit.
