[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a media image display method, and more particularly to a media image display method of a system that displays a media image on a display screen and outputs a media corresponding to the image by instructing a predetermined image.
[0002]
[Prior art]
There is a system that displays a number of media images on a display screen, selects a desired media image, and causes a system (apparatus) to perform an operation according to the media image. For example, a CD, TV broadcast, radio broadcast, or the like to be selected for listening or viewing is a medium, a CD player with changer, a TV tuner, a radio tuner, or the like, which converts the media into a visual / audio signal. Is a case where a plurality of media images are displayed on a display screen, a desired media image is selected, the media is converted into a visual / audio signal, and output.
In such a system, the media image can be moved from the initial display position to an arbitrary position by an operator operation, and the media image can be grouped according to the type, or can be displayed in a manner that can be freely superimposed depending on the usage frequency of the media image. It has become.
[0003]
FIG. 7 is a schematic explanatory diagram of the movement and overlay display method. In the figure, 51a to 53a are media images, 51b to 53b are layers (layer 1 to layer 3), and 54 is a display screen. The media images 51a to 53a displayed so as to be superimposed on the display screen 54 are managed as existing on independent layers, that is, layers 1 to 3 respectively. Each layer has a layer number, and the image on the display screen 54 is displayed on the front side of the display screen with priority given to those existing in the upper layer. In FIG. 7, the media image 53a of layer 3 which is the highest layer is displayed on the near side with respect to the display screen, and then displayed in the priority order of the media image 52a and the media image 51a. Accordingly, the overlapping parts on the display screen are displayed with priority on the one with the highest priority (in the highest layer). That is, for each picture element constituting each media image, it is checked whether it overlaps with the media image of the upper layer. If it does not overlap, “display” is displayed, and if it overlaps, “display is not performed”, display region data Create
[0004]
Each media image moves on the layer to which the image belongs. For example, the media image 52a moves on the layer 2 and is displayed on the display screen according to the above rules. In addition, when the moving media image and the media image overlapping on the display screen are completely different before and after the movement, the moving media image has been changed to the highest layer, and has existed in the highest layer. For the media image, the existence layer is changed to the next lower layer, and thereafter, the existence layer is similarly changed for all media images up to the media image existing in the layer one layer higher than the layer where the moving media image exists. Thereby, the moving media image can be displayed on the front of the display screen. Therefore, the media image can be moved from the initial display position to an arbitrary position by an operator's operation, and the media image can be grouped according to the type, or can be displayed by being freely superimposed depending on the frequency of use of the media image.
[0005]
Each media image is provided with a media table. (1) Media ID unique to the media image, (2) Layer number of the layer to which the media image belongs, (3) Media image data, (4) Display position data , (5) display area data (data indicating visible and invisible areas) and the like are stored. Therefore, the layer number stored in the media table is referred to in order of priority, and the layer to which the member belongs at the time of movement is changed.
[0006]
Each media image is input to the system control unit from the input device, displayed at an initial position on the display screen, and then moved to a predetermined position by an operator operation. That is, when a new outputable medium is generated, the input device notifies the system control unit and sends a media image. The system control unit creates a media table and displays the media image on the forefront of the initial position of the display screen that is predetermined for the input device. Thereafter, the operator moves and displays the media image at a predetermined position by operating the mouse or the like. For example, in an in-vehicle audio / visual system, if the received electric field strength of a certain TV broadcast channel exceeds a set value and reception of the channel broadcast (media) becomes possible, the TV tuner informs the system control unit to that effect. Notification is performed and a media image (for example, received image) is sent. The system control unit creates a media table and displays the media image on the forefront of the initial position of the display screen determined in advance corresponding to the TV tuner, and then moves to a predetermined display position according to the operator's operation. And display.
[0007]

[0012]
(b) Configuration of TV Tuner as an Input Device FIG. 3 is a configuration diagram of a TV tuner as an input device, 11 ₁₁ is a device main body, and 11 ₁₂ is a media correspondence table. In the device main body 11 _11, 21 antenna, 22a is first tuner, 22b second tuner, the video receiving circuit connected to the first tuner 23, audio receiving circuit, 25 is connected to the second tuner The video receiving circuit 26 is a video memory for storing one screen of video output from the video receiving circuit, and 27 is a received electric field strength detecting unit, which can receive depending on whether the received electric field strength is equal to or higher than a set level. A processor that outputs an impossible signal, 28 is a processor that performs reception control and exchanges data with the system control unit 12.
[0013]
The first tuner 22a outputs video and audio of the channel selected by the user, and the second tuner 22b switches the reception channel at a predetermined cycle under the control of the processor 28 and identifies a receivable channel. is there. The processor 28 notifies the system control unit 12 (FIG. 1) when the received electric field strength of the broadcast (media) of the predetermined channel becomes equal to or higher than the set level and the media can be output. The received video stored in the memory 26 is transmitted to the system control unit 12. If the received electric field strength is lower than the set level, the system control unit 12 is notified that media output is impossible. In the above description, two tuners are provided, but a single tuner may be used.
Although not shown, the radio tuner has the same configuration as the TV tuner. The changer-equipped CD player has an image input device that reads a CD label (media image) and a processor, and detects the CD exchange and CD removal, thereby notifying the system control unit 12 whether media can be output or not. At the same time, media images are transmitted.
[0014]
(c) When a new media that can be output as a whole is newly generated, for example, when the received electric field strength of a predetermined channel broadcast (media) exceeds a set level and the output of the media becomes possible, the device is an input device. The TV tuner 11 ₁ (FIG. 1) notifies the system controller 12 of the occurrence of media. Accordingly, the system control unit 12 assigns a media ID that is a unique identifier in the system to the notified media.
Next, the system control unit 12 is configured to create an equivalent media management table to tag media ID to the media table 13 (see FIG. 2), and notifies the media ID to the TV tuner 11 _1. The TV tuner 11 ₁ registers the media (channel broadcast) and the received media ID in the media correspondence table 11 ₁₂ . Thereafter, between the TV tuner 11 ₁ and the system controller 12, when to transfer the information on the media to identify with the media ID to the information.
[0015]
Then, TV tuner 11 ₁ is sent to the system controller 12 pictures of the broadcast channel stored in the video memory 26 (FIG. 3) as the media image. The system control unit 12 stores the received media image in the media table 13 in association with the media ID, and associates the image displayed at the initial display position assigned to the TV tuner with the media ID as save screen data. Are stored in the media table 13, and then the media image is displayed at the initial display position. Thereafter, it continues to display the media image in the initial display position since the media image is sent from the TV tuner 11 ₁ at a predetermined cycle.
[0016]
In this state, when the user selects and moves the media image by operating the mouse or the like, the image displayed at the destination is registered in the media table 13 as save screen data, and then the media that has been moved is operated. Display the image at the destination. Thereafter, the media image from the media image is sent from the TV tuner 11 ₁ at a predetermined cycle continues to display on the destination.
In a state where each media image is displayed at a predetermined position, when the user selects a desired media image from the input unit 15 and instructs to output the media image, the system control unit 12 performs audio if the selected media is audio. If it is visual, if it is visual, it is visually output on the display.
[0017]
Also, if the media that could be output becomes impossible, for example, if the channel broadcast (media) on which the media image is displayed on the display screen as output possible becomes impossible (cannot be output) due to the movement of the car. The TV tuner 11 ₁ gives a media number to the system controller 12 and notifies the system controller 12 that output is impossible. When the system control unit 12 receives the output impossible notification, the system control unit 12 reads the saved image stored in the media table 13 corresponding to the media ID included in the notification, and displays it at the position where the media image is displayed. All the management tables for the media ID stored in the media table 13 are deleted. Thereafter, the system control unit 12 instructs the TV tuner 11 ₁ to delete the media ID from the media correspondence table 11 ₁₂ . As a result, the TV tuner 11 ₁ deletes the media ID from the media correspondence table 11 ₁₂ .
[0018]
As described above, according to the first embodiment, since the media image (media image) that cannot be output is automatically deleted from the display screen, the user selects the media that cannot be output. The annoyance is eliminated. In addition, when a received video is displayed as a media image, a video with a poor reception state is not continuously displayed.
[0019]
(B) Second embodiment
(a) Principle In the first embodiment, a media image that cannot be output is simply erased. According to the first embodiment, when the media that can no longer be output can be output again, the media image is displayed at the initial position, and then the same media image of the same type is displayed by the operator operation. It is necessary to move it to a position and make it a groove. For this reason, when the input device is a TV tuner or a radio tuner, the media can be frequently output or cannot be output as the vehicle moves. Move operation is required. In other words, in the first embodiment, the information that the user classified each media image is lost and needs to be classified again, which is not preferable in terms of operation performance. Therefore, in the second embodiment, when the media can be output again, the media image can be directly displayed at the position where it was previously displayed.
[0020]
(b) Configuration FIG. 4 is a configuration diagram of a media image display system according to the second embodiment of the present invention. Components identical with those of the first embodiment of FIG. The difference from the first embodiment is (1) that an input / output switching unit 31 and an input device table 32 are provided. (2) In the media correspondence tables 11 _{12 to} 11 ₃₂ , the media IDs are associated with the media. Besides, standby information is stored, (3) standby information and input device ID are newly registered in the media table 13 corresponding to the media ID (FIG. 5), and (4) each input device is displayed on the display screen. (5) The system screen and the input device screen are appropriately displayed on the display screen.
[0021]
FIG. 5 is a block diagram of the media table 13, and (1) standby information, (2) layer information, (3) media image data, (4) display position data, (5) corresponding to the media ID for each media. Display area data, (6) save screen data, and (7) input device ID are registered. The standby information is information that indicates whether the management data of the media is to be erased from the media table or not left when the media image is erased from the display screen when the media cannot be output. If standby is instructed, it is left without being erased (continuation of management), and if standby is not instructed, it is erased (management is abandoned). The standby information in the media correspondence tables 11 _{12 to} 11 ₃₂ has the same meaning. A method for setting whether to wait or not will be described later.
[0022]
FIG. 6 is a configuration diagram of the input device table 32. The input device table 32 is for displaying an image of each input device on the display screen, and display position data, display area data, and display image data are registered in advance corresponding to each input device ID. The item of each device ID in the input device table 32 is filled with a device ID as an identifier of the input device when a new input device is connected to the system, and thereafter the device ID is transmitted and received. Add to the information and communicate with the input device. The display position and display area data may be determined by the system control unit 12 and registered in the table, or the input device may notify the system control unit 12 for registration. The system control unit 12 refers to the input device table 32 and displays an image of each input device on the display screen (lower side of the screen in FIG. 4).
[0023]
There are two types of display screens displayed on the display unit 14. That is, a system screen 14a for displaying a plurality of classified media images and selecting a desired medium, and an input device screen 14b for setting control parameters specific to each input device output for each input device. . The input device screen 14b is displayed on the display screen, and the standby information and other settings are performed for each medium. The system control unit 12 manages the system screen 14a but does not manage the input device screen 14b. Each input device does not manage the system screen, but manages its own input device screen.
[0024]
(c) Operation Hereinafter, the operation of the second embodiment will be described. The creation of the media table 13 and the input device table 32 for each medium and each input device is completed, and the creation of the media correspondence tables 11 _{12 to} 11 ₃₂ for each input device 11 _{1 to} 11 ₃ is completed. It is assumed that the system screen 14 a is displayed on the display unit 14 and the input unit 15 is connected to the system control unit 12 via the input / output switching unit 31.
When a predetermined input device displayed on the system screen 14a is selected by the input unit 15, the system control unit 12 notifies the selected input device that there has been an operation request for the device. Further, the system control unit 12 controls the input / output switching unit 31 to switch the display unit 14 and the input unit 15 to the input devices selected from the system control unit 12, respectively.
[0025]
When there is an operation request, the input device outputs an input device screen 14b for prompting setting of standby information for media that can be managed by the input device to the display unit 14 and waits for setting of standby information from the input unit 15. The standby information is set for each medium. When the medium becomes impossible to output, whether to continue management of the medium in the system control unit 12 (holding management information) or whether to abandon the management (erasing management information) Is shown.
When standby information is set for a predetermined medium from the input unit 15, the input device registers the standby information in the media correspondence table in association with the media and adds the media ID to the system control unit 12. Notify When receiving the standby information, the system control unit 12 updates the standby information of the media ID in the media table 13.
[0026]
When the above standby information setting is completed for all the input devices, the user operates the input unit 15 to display the system screen. When there is a system screen display request from the input unit 15, the input device controls the input switching unit 31 to connect the display unit 14 and the input unit 15 to the system control unit 12. Notify that there was a request.
When the notification is received, the system control unit 12 redisplays the system screen 14a immediately before switching to the input device screen on the display unit 14.
[0027]
In the state where such a system screen is displayed, when any medium cannot be output, the system control unit 12 refers to the standby information of the media ID stored in the media table 13.
If the standby information indicates that the management is to be abandoned, the evacuation screen is displayed at the display position of the medium as in the first embodiment, the media image is deleted, and all the management information of the medium is stored in the medium. Delete from table 13.
On the other hand, when the standby information indicates continuation of management, the system control unit 12 deletes the media image of the media from the system screen, but retains the management information of the media without deleting it from the media table 13.
[0028]
Then, when the media that can no longer be output can be output again, the display position data and display area data registered corresponding to the media ID of the media are obtained by referring to the media table 13, and the media is stored at the position. The media image is displayed. That is, the media image is displayed again at the display position of the media image displayed previously.
As described above, according to the second embodiment, by adding standby information, it is possible to save display position data and display area data classified by the user even when media cannot be output, and to output again. Can be redisplayed at the previously displayed position, eliminating the need for the user to move and classify media images each time.
The present invention has been described with reference to the embodiments. However, the present invention can be variously modified in accordance with the gist of the present invention described in the claims, and the present invention does not exclude these.
[0029]
【The invention's effect】
As described above, according to the present invention, when a medium to be viewed or to be listened to is defined as a medium, an image corresponding to the medium is displayed on the display screen, and a predetermined image is indicated to respond to the image. When media that cannot be output is generated, the image of the media is erased, so that the user does not have to select the media that cannot be output, and the media When a received image is displayed as an image, it is possible to prevent a video with a poor reception state from being continuously displayed.
[0030]
Further, according to the present invention, when a medium that cannot be output is generated, the image of the medium is deleted, the display position is stored, and when the deleted medium becomes output, the storage is performed. Since the media image is displayed at a certain display position, it is not necessary for the user to move and classify the media image each time, and the operation performance can be improved.
