Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to the display of a large number of betting ceremonies per race (for several screens in the past) on a television monitor, for example, on a television monitor, for example, odds information of a horse race, a bicycle race, a boat race and the like. The present invention relates to a video output device to be provided.

[0002]

2. Description of the Related Art In horse racing, for example, there are various betting types per race, such as single win, multiple wins, and consecutive wins, and various voting tickets are sold according to these betting types. Approximate dividend rates, or “odds,” are calculated for each type of ballot,
The odds information is broadcast on a large number of television receivers (aspect ratio 4: 3) installed at each racecourse and out-of-park betting ticket booth (Katsuma betting ticket sales office), etc. Are used for different purposes.

[0003] Display contents of a large number of television receivers dedicated to a large number of betting types are composed of a single still screen configuration for each betting type (for example, a frame number streak multiple odds display is a
From 18 betting ceremonies with 38 different betting styles to one still screen) to several still screen configurations in betting styles with a lot of odds information per betting style (for example, horse number streak multiple odds display is 1
There are various display methods dedicated to each betting type, up to 153 types of betting types and eight still screens (four still screens).

[0004] A teletext in which a text signal is multiplexed with a video input signal is transmitted to a teletext mixer device via a LAN of a stadium.
Data such as odds information and race content information on the day of the race sent from the system or the like are multiplexed on a video signal of the on-site television and broadcast as a teletext signal to the on-site television system (on-site cable broadcasting). The on-site television system transmits race video and odds information to the on-site venue, and uses the same equipment as a small broadcast station. However, the difference from a normal broadcasting station is that the video signal transmitted last is modulated but not transmitted as radio waves, but is broadcast in a cable (CATV network) that runs around the stadium. It is in a point. It should be noted that the channels modulated by the video signal have a total number of used channels per stadium of 4 to 12 channels.

[0005] As described above, in many places per stadium, the information system becomes complicated, so that ten channels or more are used (the ten channels or more means UHF).
The band will also be used). A new channel for the release of new odds information due to an increase in new betting ceremonies at the stadium (for example, there was only a single streak system with a frame number instead of a conventional double streak system) Was forced to increase. In view of this, a method has been considered in which new betting-type odds information or existing odds information is disclosed to a television receiver in the hall using the above-mentioned teletext. This eliminates the need to increase the number of channels and makes it possible to cope with further increases in new betting ceremonies in the future. This teletext system has been adopted by JRA (Japan Central Racing Association) for several years now, and will be spread to local racetracks and bicycle racetracks in the future.

However, in recent years, the number of betting ceremonies has increased in various types of stadiums, and the amount of odds information has become extremely large with the increase, so that it has become necessary to further increase the number of television receivers for displaying odds information. In other words, the current situation is that a dedicated television receiver is added in proportion to the increase in the amount of odds information in accordance with the new betting ceremony, or the odds information is forced to be paged in a place where expansion is impossible. In addition,
Here, “page conversion” means that when the entire screen (still image) displaying the odds information does not fit on one screen, the odds information is divided into several parts and displayed in several pages. Say.

[0007] Therefore, in the above-mentioned conventional system, the inconvenience that the number of television receivers must be increased in accordance with the increase of the new betting type or a plurality of screens are switched and displayed by one television receiver (the above-described page conversion). was there. Also, in the conventional odds information still image display method using teletext, the image information of the odds information transmitted by teletext is displayed as a still image as it is, and the odds information that can be displayed on a single screen by a television receiver. Had a limited display capability. Further, since the image information is displayed as it is, the screen configuration cannot be changed.

The present applicant has previously used a wide plasma monitor having an enlarged display area as the video output device,
An odds information output device which reconstructs the odds information and the name of the race to be used for the wide plasma monitor and displays the odds information and the race name by using the simultaneous display method has been proposed (Japanese Patent Application No. Hei 9-1997).
No. 179157). Note that the simultaneous full-screen method is a still image display method in which an entire screen is displayed at a time without performing interlaced scanning to form one screen, and this method eliminates flicker. Details of this will be described later.

[0009]

SUMMARY OF THE INVENTION The present invention relates to an improvement of the above-mentioned prior application. In contrast to the above-mentioned invention of the prior application which enlarges the display capacity and displays an image on a wide plasma display. The present invention has been improved so that it can be applied not only to wide-screen plasma displays but also to various types of receivers such as conventional TV receivers having an aspect ratio of 4: 3 and wide-screen TVs.

That is, the present invention has been made in view of the limitation of the direct display system for teletext of a conventional standard television receiver, and has been developed so as to be compatible with a conventional television receiver (4: 3 aspect ratio). In particular, numerical values) are used to minimize flickering of the image, and the Y / C separation signal is used to minimize color bleeding. The same detailed odds value display screen output as in the case of the wide plasma display is output. Conventionally, odds information is converted into character data once, and the character data is rearranged (freely changed in screen configuration) corresponding to the monitor screen for display, so that it is conventionally displayed in one screen. The number of bets that can be made is from one bet to two bets, but odds information of several bets can be displayed. Conventionally, the odds display per bet is four pages (still images). Page is turned every 30 seconds) and the use of high-definition characters enables one page, and the output is a composite signal or a Y / C separation signal. An object of the present invention is to provide an odds information output device (hereinafter, referred to as a TVS wide decoder). Note that the Y / C separation signal is a luminance signal (Y
Signal) and a chrominance signal (C signal) are mixed to separate a composite signal into a luminance signal (Y signal) and a chrominance signal (C signal), and an output terminal is provided in a VTR or the like. . This is commonly called an S terminal. High definition characters will be described later.

Although the present invention has been developed as a display device for the odds information, the configuration can also be applied to a device for displaying an ever-changing numerical value, such as a departure and arrival guidance display device at a station or an airport. Therefore, it is also an object of the present invention to provide a monitor display device which has a large data display capacity to meet these needs and has a clear image with no flicker on the screen.

[0012]

An odds information output device according to the present invention receives information on each held race in a stadium such as a horse race, a bicycle race, a boat race, etc., and calculates a dividend rate of the race extracted from the race information. In a video output device that displays the displayed odds information as a still image on a monitor, the odds information is converted into character data together with additional information such as a race name and current time, and rearrangement corresponding to the display monitor screen is performed. To temporarily store the image data in the image memory, read the image memory continuously, and read the composite video signal or Y /

[0016]

FIG. 13 shows the appearance of a TVS wide decoder according to the present invention. FIGS. 14 and 15 show the connection outline and installation outline of the TVS wide decoder of the present invention. The TVS wide decoder according to the present invention is a PDP wide decoder (Japanese Patent Application No. Hei 9-179157) previously proposed as a new information medium using teletext data.
No.), as shown in FIG.
The above P that the odds information of 8 heads can be displayed on one screen
The display function of the DP wide decoder can be used as it is for an existing conventional standard television monitor. Further, the TVS wide decoder of the present invention can be used for a PDP or a multi-TV by switching the output. FIG. 15 shows the relationship between the existing teletext display system and the TVS wide decoder of the present invention. In FIG. 15, the odds printer is a system for printing odds information on paper.

The present invention can also be used for a wide plasma monitor. As the wide plasma monitor, for example, a product made by Fujitsu General (trade name) using a PDP (wide plasma display panel).
A 2 inch wide plasma monitor is used.

When a composite (video composite signal) is directly input to a monitor using the conventional still image display method as it is, the composite signal is separated into RGB and displayed as an image, so that the video becomes unclear and the odds information is displayed. In the case of viewing a still image, if the numerical value representing the odds information becomes small due to the interlaced scanning, it becomes very difficult to see (a flickering wave up and down). In addition, the conventional odds information display system using a standard television receiver cannot change the screen configuration because the image information is displayed as it is, and the aspect ratio of the standard television receiver is 4 to 3, which is a wide screen. Since the aspect ratio is different when the aspect ratio is 16: 9, when the wide screen is used, the effective area cannot be fully used (the screen becomes small). Alternatively, since the odds information displayed on the standard television receiver has an aspect ratio of 4: 3, if the odds information is enlarged and displayed on a wide-screen television as it is, only the screen spread in the horizontal direction is obtained, so the aspect ratio is 16: 9. There is no point in doing what you do.

Conventionally, a character adapter for displaying a teletext image on an image is currently known to have a ratio of 4: 3, but there is no 16: 9 corresponding to a wide screen. The differences between the normal character adapter and the TVS wide decoder of the present invention are as follows.

(1) Capable of supporting 16: 9 wide screen (This TVS wide decoder is designed so that it can be used on a 4: 3 standard television, based on a 16: 9 wide screen. ing.). (2) Because the figures of the characters use their own characters (each Gothic), they are clear. (3) 852 horizontal dots and 480 vertical lines can be displayed, and these can be changed. (4) If a wide plasma monitor is used as the monitor, since the wide plasma monitor is a simultaneous display method on the entire surface, even a still image has no flickering of an image and an image which is easy on the eyes can be obtained.

Table 1 shows a comparison between the PDP wide decoder of the prior application and the TVS wide decoder of the present invention. The main difference between the two systems is that the former is output as an RGB signal to a PDP wide monitor, whereas the TVS wide decoder of the present invention uses a composite signal or Y /
This is a point output to the monitor by the C separation signal (S terminal).

[0022]

[Table 1]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows the configuration of a system used in the present invention. First, a case where the monitor is a wide plasma monitor will be described. In FIG. 1, 1
Is a tuner section, which receives at any time race information indicating the content of each race to be held, and outputs odds information indicating a payout of the race extracted from the race information to a video channel (V
(One channel or two channels in the HF or UHF band), a function of converting the input RF signal into a composite video signal and audio signal, and supplying the video signal to the switcher unit 3 and the audio amplifier unit 2. Have. As the odds information, information multiplexed as a text broadcast on the video system of the in-site cable television system provided in the stadium in advance is used.

The audio amplifier unit 2 amplifies the audio signal input from the tuner unit, converts it to a specified audio signal, and sends out a signal that can be input as a stereo input (monaural) to the audio input of the monitor.

The video distribution and switcher section 3 amplifies the video signal input from the tuner section by a video amplifier, stabilizes the video signal level to a specified level, and combines the video signal with a DEC section, a sync separation waveform shaping section, and a data separator section. A video signal is supplied as a video signal (composite signal). Also, a video signal input (R) from the outside (VIDEO IN)
(In the case of inputting directly as a composite video signal of the standard NTSC system without converting to F signal) and the video signal input.

The DEC unit 4 decodes the composite video signal input from the video distribution and switcher unit 3 (converts the composite video signal into a Y / C separated signal) and outputs the composite video signal distributed as it is to each output. I do.

The sync separation waveform shaping section 5 shapes the waveform of an input video signal and separates a horizontal sync signal (HD) and a vertical sync signal (VD), which are sync signals included in the composite video signal. And supplies it to the DRT unit 6 described later. The data separator 6 separates the character data multiplexed into the video signal as a teletext, adds an equalized waveform, and supplies it to the DRT 7.

The DRT unit 7 samples the character data from the data separator unit 6, corrects the error, decodes the sampled data into 8-bit parallel data, and supplies it to the CPU unit 8 as text data.

The CPU section (character encoding / decoding) 8 is provided with character data (packet data) from the DRT.
Is a part for decoding character data into character data. The character data is used to extract dot data necessary for displaying a screen from the kanji ROM and the character memory (high-quality character ROM), write the image data into the image memory, and From the control of the O. program memory, the control of the D / A converter and the output control to the transmission switcher unit 9 are performed. In addition, the performance is 16 bits inside / 8 outside.
Bit (CPU) and 8 Mbit (Kanji ROM) are used.

The transmission switcher section 9 switches the transmission signal in accordance with the control signal transmitted from the CPU section 8, and transmits information (switch control signal and individual recognition signal) together with the race information included in the character data. Etc.) to switch the output video signal. A signal to be switched as an output video signal to the television receiver is a composite video signal (VIDEO OUT) input as a moving image (race video or the like) from the DEC unit 4, a Y / C separation signal (S terminal), and a signal from the ENC unit 10. A composite video signal (VIDEO OU) input as a still image (odds information, etc.)
T) and a Y / C separation signal (S terminal).

The ENC unit 10 includes a D / A converter unit 13
Encodes the analog RGB signals (still images such as odds information) input from the
/ C separated signal).

The image memory unit (A) 11 has a function of writing / reading data input from the CPU unit 8 by switching control with the image memory unit (B) 12 and sending the data to the D / A converter unit. . The image memory unit (A) 11 and the image memory unit (B) 12
It has the memory capacity of 2 images (total of 2 images).
When the PU unit is writing to the image memory (A) 11, the data in the image memory unit (B) 12 continues to be sent to the D / A converter unit, and the writing operation to the image memory (A) is completed. Thereafter, the image memory unit (A) and the image memory unit (B) are switched during the blanking period under the control of the CPU, and the state shifts to a state where the data in the image memory unit (B) 12 is continuously transmitted to the D / A converter unit. Further, when performing the next data update, the image memory unit (A) 11 and the image memory unit (B) 12 perform the opposite operations, and as a result, continuously transmit image data.
That is, the image memory units (A) and (B) alternately invert and transmit the image data continuously.

The D / A converter section 13 is a section for converting the digital data input from the image memory section into an analog RGB component image output and outputting it.
It has a function of converting a still image such as odds information into an RGB signal and outputting it to the ENC unit 10 as an analog RGB signal.

The SG address counter unit 14
(SYNC generator) function, 16M
Hz clock from the oscillator, and HD / VD
/ SC / SYNC, etc. to generate a synchronizing signal to the ENC section, etc., and to generate an address counter signal output from the image memory section, thereby generating an image memory section (A) and an image memory section (B). ) Has a function to send out. Then, a BLK for generating blanking on the image output is generated, and a BLK (synchronization signal blanking) signal is supplied to the D / A converter unit.

The power supply unit 15 and the power supply unit 16
Input 100V, and through power supply filter / fuse etc.
A stabilized power supply of C + 5V and + 9V is generated, and each power is supplied to the tuner board and the decoder board.

Here, a full-screen simultaneous display method in the case of a wide plasma monitor will be described. The image projected on the cathode ray tube has a scanning line number of 525 lines in the standard NTSC system, but uses the interlaced scanning method and 262.5 lines ×
I make one screen twice. However, this interlaced scanning method is inconspicuous in the case of a moving image, but in the case of viewing a still image, since two scans are viewed as one screen, each display portion moves up and down each time, causing flickering. In other words, there is a drawback that the image appears to fluctuate up and down, and the numerical value of the still image, particularly the odds screen, becomes difficult to see.
Therefore, in the case of a still image, it is preferable to display the entire screen at once without performing interlaced scanning in order to form one screen because flicker is eliminated. This is called an all-simultaneous method. This full-screen simultaneous display method is performed as follows.

First, an analog composite signal in an interlaced scanning system (interlace) which is a horizontal scanning frequency (15.75 kHz) of a general NTSC system is output from a wide decoder. When the wide plasma monitor receives the output, the interlace signals are stored in the memories (the first field and the second field are stored separately), and when one frame is completely stored, one sheet is collectively obtained. The image data of the minute is displayed.

For displaying moving images (especially fast-moving screens such as horse races), interlaced scanning is preferable to interlaced scanning because the response to the change is twice as fast. Conversely, the apparatus of the present invention displays moving images. At that time, switching is performed by a control signal, and a composite signal on a normal video output side is directly transmitted.

FIG. 2 shows an example of an image displayed on the monitor (table of odds of winning streak number 18). FIG. 3 is a photograph of the odds table shown in FIG. 2 actually displayed on a 36-inch wide-screen television having an aspect ratio of 16 to 9 on a full screen. FIG. 4 is a photograph of the odds table of FIG. 2 actually displayed on a 36-inch wide-screen television with an aspect ratio of 4: 3 (the screen in this case is shorter in the horizontal direction).

As described above, the image is stored in one of the image memories.
Continuing the contents of 1 and 12 (actually, memory (A),
It is displayed by reading (alternately (B)). FIG.
In the above, 17 and 18 are held race names, and held information (text data) input from teletext is stored in the C.
The PU reads the corresponding logo from the character memory, converts it into a display pattern, and displays it on the screen.

Numeral 19 indicates the current time, and a number frame 21 indicating a horse number or the like is fixedly displayed on the screen. The screen is displayed in color, the number frame 21 indicating the horse number and the like is yellow, the number frame 22 such as the horse number and the like of the winning streak is outlined in red, the odds value 20 is outlined in dark blue, and a popular combination ( In the case of 10.0 times or less on the screen), all the odds values are displayed in pink, and on the contrary, the less popular combinations (1, 0 on the screen)
(00 times or more), the odds values are all displayed in yellow. In particular, the most popular ("4-6" on the screen)
Only 6.2 times the color) may be displayed in a particularly prominent color. The odds numbers on the screen 20 are the odds information (text data) taken in from the teletext broadcast by the CPU.
The character data is converted into character data and stored in a predetermined position of the image memory, which is read out and displayed on a monitor. Since the odds change every moment, the odds are updated with new information every predetermined time.

Next, the details of the system configuration of FIG. 1 will be described in more detail. FIG. 5 is a detailed diagram showing a connection relationship between the tuner unit and the CPU unit. The tuner unit 1 selects a designated channel of the RF signal, and outputs a necessary signal (VD / HD / digital composite signal) to the CPU unit from the received signal.
At the same time, an audio signal (AUDIO OUT-1 / 2) and a video signal of a moving image (VIDEO OUT / decoded S terminal OUT) are output. VD is a vertical synchronization signal,
HD is a horizontal synchronizing signal. The CPU unit 8 analyzes the character signal data output from the tuner unit 1, performs formatting and conversion into a character code, and
A video signal is formed as a B signal, and the RGB signal is further encoded to obtain a still image video signal (VIDEO OUT /
The video signal of the moving image from the tuner unit and the video signal are switched by the transmission switcher unit and output as a composite signal or a Y / C separation signal (S terminal).

Then, in step 72, D
The character data sent from the RT in packet units is created on one page and written to the built-in memory. Read the venue as data from the above-mentioned venue information (Step 7
3) Read which race is currently displayed from the captured essential points (step 74). Next, the number of race registrations to be displayed is read from the captured essentials (step 75), and the release betting ceremony to be displayed is also read (step 76). Thereafter, it is confirmed that the reception has been completed (step 77), and the process proceeds to screen layout creation. If the reception has not been completed, a normal moving image (broadcast contents of the TV in the hall) is displayed.

FIG. 17 is a flow chart of packet capture, in which character data sent from the DRT (procedure 80) is captured one packet at a time in the minimum unit (22 bytes) of teletext (procedure 81). It is checked whether the creation of a message for one page is completed (procedure 82), a checksum is performed (procedure 83), and if OK, the data is stored in the built-in memory (procedure 84). ). This packet capture processing is performed for each H of 14H (holding essential point), 15H (odds value), and 16H (display control).
When the data is stored in the built-in memory, each data is stored at a predetermined memory address.

FIG. 18 shows a flowchart of the screen layout creation. When screen layout creation is started (procedure 91), venue data (A, B, C) is first acquired (procedure 92), and then the race number to be displayed (procedure 9)
3) Acquire the number of registered runners and the betting type (single type, multiple type, etc.) (procedure 94), and acquire the place name and race name to be displayed (procedure 95). Next, an odds value to be displayed is obtained (step 9).
6) Built-in display format, such as horse number streak double
Select from OM (procedure 97). According to the display format, the display data is developed in a G-MEM (graphic memory), and after the development is completed, the G-MEM is switched (step 98). There are two G-MEMs and they operate alternately. This completes the screen layout creation (procedure 9).
9).

Next, "high definition characters" will be described.
A high-definition character means that the image projected on a cathode ray tube or the like has a scanning line number (per screen) of 52 in the case of the standard NTSC system.
As shown in FIG. 9, one screen is formed by 265.2 × 2 times by interlaced scanning. (on the other hand,
Since a personal computer, a video game, and the like employ non-interlace (sequential scanning) as shown in FIG. 10, the screen is easy to see. )

When a still image is projected by this interlaced scanning, flickering (edges of displayed characters are displayed every other time and appear to fluctuate up and down) because two scans are always viewed as one screen. Yes, still images, especially the odds screen, are so small that they are hard to see. For this reason, in displaying numerical values such as odds numerical values, the lines were made thicker in advance so as to prevent flickering, and numerical values were formed using characters (shadow conversion) in which the number of character dots was increased. This example is shown in FIGS. FIG. 11 is an example of display data before shadowing,
FIG. 12 shows display data after shadowing. As can be seen, the lines 31-34 of FIG.
Are doubled up and down like lines 35-38. Since the flicker caused by the interlaced scanning greatly changes in the vertical direction, the shadowing can be prevented from flickering in the vertical direction (addition of upper or lower rows), that is, in the double only in the vertical direction.

That is, the "high-definition character" is a character in which flickering of characters in interlaced scanning is newly reduced and flickering of each odds value is reduced as much as possible. Even if a still image is viewed with a normal receiver using the / C separation signal output, the still image can be viewed as an image with reduced flicker.

Next, ID management will be described. ID
Is a management number set by the stadium for each management number of the TVS wide decoder, and a maximum of 9999 units are displayed in the stadium with serial numbers that do not overlap. By using this individual ID number to add a control signal to teletext data and controlling the character generator of each device, the video content (video program) displayed from the television receiver to the PDP wide plasma monitor Can be managed and changed from a central location. This is because the needs of the audience vary depending on the location of the monitor and the content of the race (for example, a prize race), and the display control of various monitors is to be performed using a personal computer etc. in response to the needs. It is.

The present invention has been developed as a display device for the odds information, and the description of the embodiments has been described as a display device for the odds information. It can also be used for devices that display ever-changing numerical values, such as display devices. That is,
The data display accommodating capacity corresponding to these needs is large, and the present invention can also be applied as a wide monitor display device for clear images without screen flicker. Since the video output device of the present invention is very excellent as a large-screen still image display device in that it is clear and easy to see, its application field is not limited to the above-mentioned odds information display device. Application is conceivable.

[0063]

The effects of using the odds information monitor output device of the present invention are as follows. (1) Odds information is displayed on a large monitor screen, and the information capacity is about three times as large as that of a conventional TV which directly displays image information from teletext on a standard TV. That is, even when the odds information monitor output device of the present invention is used, the conventional standard TV 3
The display for each vehicle is possible. The above-mentioned standard usage is a case where the size of characters on the screen is easy to see when the number of spectators in front of the monitor is assumed to some extent. Recently, even a standard television has a large size (for example, 36 inches).
A wide screen type is commercially available. Since the odds information monitor output device of the present invention converts text data into characters in the CPU and displays the characters, using a large screen monitor allows characters on the screen to be relatively small and a larger monitor to be used. For example, it is possible to further increase the information capacity. Also, if it is assumed that the viewer sees at a close distance, the characters on the screen can be made relatively small, and it has been confirmed that a monitor with a small screen of about 12 inches has about three times the information capacity described above. (On the other hand, in the odds information display system using the conventional television receiver, since the image information of the still image supplied from the teletext is displayed as it is, the screen configuration cannot be changed. Compress about 3 times to 1
When displayed on the screen (for example, on three screens), the numerical values become jagged, and it is not possible to read such detailed numerical values. )

Incidentally, in the case of this embodiment, the number of dots of the font to be used is 24 × 24 (in the case of full-width), 24 × 12
(Half-width case), and the screen is 852 dots x 480
Since it is composed of dots, the effective maximum display characters are 35.5 in digits and 20.0 in lines. The actual number of digits used is 32 characters (24 × 24) / 64
(24 × 12), the number of rows is 19 rows.

(2) When the odds information monitor output device of the present invention is used, the display character is reconstructed as described above, so that the reconstructed display character has a small flicker on the screen even by interlaced scanning. Since a high-definition character is used and a Y / C separation signal (S terminal) is used, color bleeding and flicker such as an odds value can be minimized, and a detailed odds value can be displayed. Therefore, the information amount of the odds can be increased, and the odds display screen for each betting type can be checked at a time.

(3) In connection with the above (2), when the odds information monitor output device of the present invention is used, since the character numbers use their own characters (each Gothic), the font itself is also changed. It is clear. That is, it is possible to select the most suitable font (logo) according to the installation state of the monitor, so that the characters can be sharpened.
(On the other hand, in the odds information display system using the conventional standard TV, since the image information of the still image supplied from the teletext is displayed as it is, the character cannot be changed as described above.)

(4) The odds information monitor output device of the present invention can display 852 dots horizontally and 480 lines vertically.
It is also possible to change this. That is, since the odds information monitor output device of the present invention converts text data obtained from teletext into a monitor compatible using text data, the conversion specification can be freely changed. The number of vertical and horizontal dots can be increased or decreased as necessary. In this embodiment, however, 852 horizontal dots and 480 vertical dots are used.
Line display is adopted.

(5) When the odds information monitor output device of the present invention is used for a PDP wide plasma monitor, since the wide plasma monitor is a simultaneous display system on the entire surface, there is no flickering of the image and an image which is easy on the eyes can be obtained. . As described above, the standard T of the interlaced scanning method for a still image is used.
When the display is performed in V, the display moves in an odd-numbered and an even-numbered scanning line each time, so that it appears to be flickering. When a wide plasma monitor output device is used, there is no flickering of the image as described above because of the full-screen simultaneous display method in which full scanning is performed every time.
