Description

  The present invention relates to a broadcasting system and apparatus for transmitting a television broadcast that is vertically displayed with a television receiver placed vertically and displayed in a full length.

  It is well known that a television receiver is used as an advertisement display means such as a poster in a building or a limited area.

  However, a normal television receiver has a horizontally long screen, and a usage mode in which this is displayed on a full screen on a vertically long screen has not been assumed conventionally. The landscape screen of posters and other advertising displays (for example, commercial animations) has the disadvantage of not getting much attention because of its familiarity in the city. For example, in the case of an advertisement for a portrait poster, a fashion image with a human figure, or a sporting event, the advertisement is more effective because the portrait screen attracts more attention.

  Conventionally, paying attention to the advertising effect of the above-mentioned portrait screen, it has been proposed to use a television receiver in a form of use for displaying the entire screen on the portrait screen as an advertisement display means such as a poster (Reference 1, Reference 2). ).

  However, the above-mentioned proposal is to display an output image such as a VTR by rotating it 90 degrees, and the 90-degree rotation of the image is processed on the terminal side, and the signal form is changed at the stage of television broadcasting. It is not a 90-degree rotated image.

  In view of the above viewpoint, the present invention proposes an inexpensive area broadcasting system that uses a normal television receiver with a full screen display of a vertically long screen.

  First, an outline of conventional digital broadcasting (data broadcasting) which is a premise of the present invention will be described. As shown in FIG. 9, a conventional digital broadcast (data broadcast) broadcasts a background image file 111, a file 112 other than the background image, and a BML file 111 in which the image file name and coordinates for displaying the image file are described. The data is input to the storage device 113 in the device 117, packetized (114), and transmitted as a broadcast wave subjected to OFDM modulation (115).

The broadcast wave is displayed by pasting an image other than the background image on the background image as shown at 116 in each television receiver. Digital broadcasting standards are well known,
http://www.arib.or.jp/tyosakenkyu/kikaku_hoso/hoso_kikaku_number.html
It is published in

  The standard of the above digital broadcasting is a standard that assumes a horizontally long screen. Digital broadcast waves can also include data broadcast information, and the data broadcast standard is also a standard assuming a horizontally long screen.

The data used in the data broadcasting is as follows.
-BML file-Background image file-Image file other than background image-Other than the above The BML file is a description of coordinate information for displaying an image file.

  In the data broadcasting, an image file of a background image (entire screen) is designated. A conventional background image is a horizontally long image 111. The image file 112 other than the background image is displayed on the background image, and is created on the assumption that the entire screen is displayed horizontally. The PNG format can be used as the image file format.

  Note that PNG is an abbreviation for Portable Network Graphics and is one of image formats. It was developed with the aim of being widely used on the WWW instead of JPEG and GIF.

The outline of the area broadcasting system of the present invention will be described below with reference to FIGS.
In FIG. 1, an advertisement display screen such as a poster to be broadcasted is created on a PC (personal computer) 1. The screen is stored in the image storage device 2.

  The stored image 3 is input to the broadcast transmission device 4, and image processing described later is performed in the broadcast transmission device 4. As shown in 7 of FIG. 1, a standard horizontal digital television receiver is set in the vertical direction. The TV broadcast is installed such that a digital image such as a poster is displayed vertically on a full screen on a vertically long screen of the television receiver installed vertically.

  Television broadcasting uses data broadcasting of area broadcasting that is broadcast in a limited area such as in a building. For television receivers, without any improvement, the conventional horizontally installed receiver is used in the vertically long direction, that is, in the direction rotated 90 degrees from the conventional one. In the area broadcasting referred to in the present invention, any transmission path from the broadcast transmission device to the television receiver may be used.

  For example, a mode in which radio waves are transmitted from a broadcast transmission device to the atmosphere by a transmission antenna, received by a reception antenna and received by a television receiver, or transmitted from a broadcast transmission device to a television receiver by a coaxial cable, etc. There is.

  The above data broadcasting does not display a normal television reception screen (video) on the data broadcast reception screen of the television receiver, and only a digital image such as a poster is displayed vertically on the full length screen. The In this way, unlike a normal data broadcast broadcasted by NHK or private broadcasting, the display screen is only a data broadcast that does not have a reduced normal TV screen (video).

The above system means that the vertically long screen 7 is already formed in the broadcast transmission device 4 and the broadcast wave is transmitted.
That is, when the broadcast wave is received by a normal television receiver, a vertically long screen lying down is displayed as shown in 6 of FIG.

  The present invention is a broadcasting system in which a digital image such as a poster is displayed vertically on a vertically long screen and displayed on a full screen by using a normal television receiver in a vertical position as shown in FIG. It is a broadcast transmission device used in the system. In FIG. 1, the television stand portion is also displayed. Needless to say, in the present invention, the television receiver including the stand portion is suitable for vertical installation. For example, a wall-mounted television is preferable.

  In the first embodiment of the broadcast transmission system with vertical / horizontal conversion function of the present invention, as shown in FIGS. 1 to 4, the vertically long image 3 is generated by the vertical / horizontal conversion unit 20 (FIG. 2) in the broadcast transmission device 4. As shown, the image is rotated 90 degrees to the image lying on its side. The broadcast transmission device 21 has the same function as the conventional broadcast transmission device.

  More specifically, as shown in FIG. 3, the digital image such as the poster is a multi-layer screen of a background image 30 and partial images 31 and 32 pasted on the background image, and the background image is rotated by 90 degrees. Together with the image data, the partial image also forms a rotated image 36.37 with its position information, and the multi-layer screen is combined with the position information of the partial image to create and transmit a broadcast wave.

That is, in FIG. 3, the background image 30 is rotated 90 degrees to convert it into the image 35, and the partial images 31 and 32 are also converted 90 degrees to form the partial images 36 and 37. The final image to be transmitted is an image obtained by pasting the partial images 36 and 37 on the background image 35.
At this time, it is important to reproduce the partial images 36 and 37 by accurately aligning the positions of the partial images 31 and 32 with the original image in order to accurately convert the original image into the transmission image 47.

  For this reason, the image storage device 2 (FIG. 1) has a database for storing the position information 45 of the partial images 31 and 32, and software for converting them into the corresponding positions of the images 36 and 37 to be transmitted. Is included in the coordinate conversion processing unit 65 (FIG. 4) of the broadcast transmission device 4. Therefore, it is necessary to store the corresponding position information of the images corresponding to the images 31 and 32 to be transmitted together in the database. The position information 46 converted to the position corresponding to the original image of the images 36 and 37 to be transmitted is created, and based on the converted position information 46, the positions of the partial images 31 and 32 are accurately matched to the original image and the background. The image 35 and the partial images 36 and 37 are reproduced, and the reproduced portrait image 47 is transmitted as a broadcast wave by the broadcast transmission device 75 (FIG. 4).

  FIG. 4 shows a specific image of this image conversion. In FIG. 4, the background image 62, the partial image 63 other than the background image, and the position information (BML data) 61 of the partial image are subjected to the image rotation processing (66, 67) and the coordinate rotation processing (65), respectively. The images are converted into landscape images 71 and 72, and these are combined. As shown in 78, a vertically long image displayed in landscape orientation on a normal television receiver is placed on the broadcast wave.

  FIG. 5 shows a partial image 80 that is displayed in a landscape orientation on a normal television receiver, and is displayed as a portrait image 81 for a portrait image on a vertical television receiver.

  At this time, the partial image 80 displayed in the landscape orientation on the normal television receiver is also erected as the portrait image 79 on the portrait television receiver in the positional relationship of the partial image 81 on the portrait screen 79 in the portrait television receiver. The image is accurately displayed and moved to the position of the partial image 81 of the vertically long image. In this case, the coordinates are displayed with the upper left corner as the origin (circles in FIG. 5) 82 and 83.

-Since the TV screen is horizontally long, a horizontally long screen as shown in FIG. 5 (a) is usually assumed, but a vertically long screen as shown in FIG. 5 (b) can also be expressed by standing the TV. is there.
A BML file is a file that describes where to place an image in this area.
-The coordinate system is expressed with the upper left as the origin.
-The display position of the image file is expressed by the upper left coordinates (◯ in FIG. 5).
Here, FIG. 5 is expressed to show the concept of the coordinate system, but the actual BML file is a text file.
For example, the image displayed at (x, y) = (301, 186) is specified by the following text sentence.
<object id = “icon1” class = “airship” data = “/ 40/0006 / airship.png” style = "left: 301px; top: 186px;" type = "image / X-arib-png"/>
In the above description, "style =" left: 301px; top: 186px; "" is position information.

The representation of the coordinate system in the BML file is as follows.
In BML, coordinates are expressed as Top = 23px, left = 10px, bottom = 55px, right = 48px, etc.
-Also, the horizontal width and vertical width are expressed as width = 38px, height = 32px, and the like.
Px is an abbreviation for pixel.

A more detailed explanatory diagram of the positional relationship between the partial images 84 and 87 is shown in FIG.
In FIG. 6, the equation for the coordinate conversion of the image display position is as follows.
CX = AY
CY = ZX-AX-BX

FIG. 7 is an explanatory diagram of the image rotation process.
In principle, as shown in FIG. 7 (a), the order of the images 90 configured in the order of the matrix, such as 1, 2, 3,... Then, conversion may be performed in the order of the matrix of the vertically long screen, such as 1, 2, 3... 10, 11, 12.

  As described above, this is realized by replacing the pixels, but this is a technique that is very widely used in general as seen in FIG. 7B. For example, as shown in FIG. 7B, the image can be rotated by pressing the portion 95 with Windows (registered trademark) standard image display software.

  In addition, it is well known that data broadcasting has a function of detecting a zip code and sends out a local data broadcast corresponding to the zip code to be sent. If a predetermined image corresponding to the zip code is sent using this zip code sending function, a poster or the like corresponding to the receiving place can be displayed on the receiving side. Also in this case, the image storage device 2 has a database for storing image data corresponding to the zip code.

  Thus, the area broadcasting system of the present invention has a database storing the image data rotated by 90 degrees, the position information of the partial image, and the link between the postal code and a digital image such as a desired poster. The digital image such as the poster is displayed as desired by setting the zip code of the receiver.

  As shown in FIG. 8, the second embodiment of the broadcast transmission system with the aspect conversion function of the present invention creates a rotated image (BML file 100, background image 101, image 102 other than background) in advance by the PC 1 of FIG. These are input to the storage device 103 of the broadcast transmission device 107.

  In this manner, the received image 106 of FIG. 8 can be displayed by placing a vertically long image on the digital broadcast wave from the beginning. When the television receiver of FIG. 8 is set up, a vertically long image is displayed.

  When displaying the same poster screen on a large number of terminals for a long period of time, it is efficient to create a vertically long image in advance on a personal computer and broadcast it on a normal broadcast transmission device as in the second embodiment. Is. In this case, since the broadcast transmission apparatus may be an existing one, there is an advantage that the existing system can be used as it is.

  On the other hand, when changing images of various types of posters in a short period of time (for example, in units of hours or minutes) or in the case of moving images, a vertically long landscape image is created in advance on a personal computer as in the second embodiment. It takes time and effort, and is not always efficient. As in the first embodiment, it is more efficient to use a broadcast transmission device incorporating an image rotation device. Also, the first embodiment is more efficient when different types of images are distributed to many locations.

  The broadcast transmission system with a vertical / horizontal conversion function of the present invention can be used as an arbitrary poster for each television receiver by using a plurality of ordinary television receivers when performing area broadcasting in a limited area such as a building. Thus, the installation cost as an advertising tower is small, and the convenience is high, so the industrial utility is high.

  In addition, each advertisement tower (TV receiver) can select the screen of the corresponding broadcast wave poster, etc., simply by changing the received postal code, so there is no need to replace paper posters as in the past, and video There is also a convenience that can be played. Furthermore, compared with the conventional screen installation type using a television receiver, the conventional type is a troublesome operation because it is a video processing on the terminal side, whereas the broadcast transmission system with a vertical / horizontal conversion function of the present invention. The broadcast side can select all distribution images, and the receiving side can be used without modifying a normal television receiver, so that the convenience is high and the industrial utility is also high.
