That is, when the control data is transmitted from the host computer to the apparatus through communication, the control data is converted into display data, and the content corresponding to the display data is displayed on the LED. The animation moving image data stored in the external memory in advance is displayed on the LED by the control data transmitted and transmitted from the host computer. Along with this LED display, an audio output linked to the display content is expressed. Then, when there is no control data by communication transmission, that is, in the case of only this apparatus, an LED is displayed according to the display data registered and stored in the external memory.

In the animation moving image display and the flow of audio data,
First, when the power is turned on, the presence or absence of an external memory card is checked. If there is a memory card, header information is obtained, animation moving image display data (for example, 4 kilobytes per frame) and audio data are transferred, and data display and audio output are performed. In this audio correspondence, audio is reproduced and generated in synchronization with the sentence data and the animation moving image data. That is, in the audio reproduction, the audio data is output in conjunction with the display data. This will be described with reference to FIG. 2. The composition / switching conversion unit 23 performs data conversion on the sentence (text) data 21 and the voice data 22, stores the converted data in the memory storage unit 24, and stores the converted data in the IED display unit 25. To display. On the other hand, after the data conversion, the animation video data 26
Is displayed on the LED, and a sound linked to the displayed contents is generated by the sound output unit 27. At this time, the PCM / ADP
Voice expression is performed using a CM voice reproduction board. As described above, the sound reproduction output is performed in conjunction with the animation moving image or in conjunction with both the animation moving image and the text characters.

As described above, the present invention has a configuration in which voice expression can be performed in conjunction with animated moving images and text characters.

Display expression can be performed.

[0009]

Embodiments of the present invention will be described below. In this example, the main control means 3 serves as a data conversion unit for converting animation moving image data and text character data into display data.
And a voice control unit 41 as a voice code recognition unit for recognizing a voice code based on display data.
It is configured to output a sound by 0. This device uses text character data control for data display control,
While animation video data control, arbitrary line (row) control, arbitrary dot control, and random lighting control are adopted, voice control employs a synchronous system that reproduces audio in conjunction with text character data and animation video data. .

As shown in FIG. 3, the control circuit of this device is as follows.
A main control means 30 connected to a switching power supply 29 and including a CPU 31, a communication control unit 32, a DP-RAM 33 and the like; an audio output unit (speaker) 40 connected to the communication control unit 32 via an audio control unit 41; It comprises a computer 50 and an LED display unit 60 connected to the DP-RAM 33 via an LED control unit 61. CP in main control means 30
U31 functions as a data conversion unit for converting animation moving image data and text character data into display data;
I / O port 34 between PU 31 and DP-RAM 33
And the internal memory card 35, and S
A RAM 36, a ROM 37 and a flash memory 38 are incorporated; The LED display unit 60 displays animation moving image data and text characters based on the display data, and has an appearance configuration as shown in FIGS.
A large number of LED elements 62 are provided on the front,
3, and is stored in a storage case 67 including a lower case portion 64, an acrylic panel 65, and a side cover 66.
Regarding the arrangement of the internal components of the storage case 67, a remote control light receiving unit 68 and a noise filter 69 are provided at the lower center and lower right of the front, respectively, and the switching power supply 29, control board 70, LAN board 71 And a speaker audio board 72, while a metal plug 73, an AC outlet 74, a fuse holder 75, and an RS-232C
(76) is provided.

The LED display colors according to the present embodiment correspond to four colors of black (non-lighting), red, green, and orange. Character (font) data is converted to display image data. That is, as shown in FIG. 7, first, numerical data / JIS code is expanded into text character data, converted into display image data in which one cell is 1 byte, and this display image data is stored in lower 2 bits. The data is transferred to the DP-RAM 33 and the LED display 60
Lights up. At this time, four bytes of data A, B, C, and D, each of which consists of two bits, are packed into one byte in that order, and DMA (Direct Memory A) is used.
access). In the above-described display control of text character data, as shown in FIG. 8, one dot of each line of the display image data (text character data on the S-RAM) is composed of 4 bytes, and the DP-RAM 33
When data is transferred to the data bus 31A of the CPU 31,
Are thinned out, 4-byte data is packed into 1 byte, and the DMA transfer is performed by this packing process.
Similarly, when converting animation moving image data to display image data, data is transferred using DMA. FIG.
As shown in (1), first, the bitmap image data stored in the internal memory card unit 35 is transferred to the DP-RAM 33, and the LED display unit 60 is turned on. At this time, four bytes consisting of data A, B, C, and D are packed into one byte and stored in the internal memory card unit 35 in that order. Even in this display control, the bitmap data is stored in the DP-R
When transferring data to the AM 33, the data bus of the CPU 31 is thinned out and DMA transfer is performed.

Next, in the arbitrary line (row) control and the arbitrary dot control, the display image data handles the lighting data of one dot as one byte. For this reason, the LED can be turned on in an arbitrary line unit or an arbitrary one dot unit, and the lighting control is facilitated. In the random lighting control, the lighting position and the light-off position of the LED display are determined using a random number, and the display data is turned on and off. The display color of LED lighting is the LED of the next order data to be displayed after that.
Use the display colors as they are. The lighting data table and the lighting data table (X-axis and Y-axis coordinate data are lighting / light-off position data) include one row of 4K dot data, two rows of 8K dot data, and four rows of 16K dot data. There is minute data. In the display control table, the number of dots to be turned on / off in one frame is n, and the number of repetitions is m. When the number of dots n> 0, the data of n dots is repeated m times. In this case, the frame (screen) is skipped m times, and when n <0, the LED display is terminated. By performing random lighting control using the two data tables, an LED display pattern can be easily added.

In the audio synchronization control, the sound is reproduced in synchronization with the animation moving image data. In this embodiment, the sound is reproduced in synchronization with both the animation moving image data and the text sentence data. As shown in FIG. 10, the system configuration of the audio synchronization control is such that the CN1 of the CPU 31 storing the audio code 39
5, a speaker 40 is connected via an RS-232C of an audio reproduction board 41A (audio board control unit 41), and data is transferred from the CN 15 to the RS-232C. The audio reproduction board 41A functions as an audio code recognition unit that recognizes an audio code based on display data, and the specification of the audio reproduction unit is PCM (8 bits) / A.
DPCM (4 bits) audio encoding method, sampling 8KHz / 16KHz / 32KHz, reproduction band 50 ~
6400Hz (at 16KHz) / 50-12800Hz
(At 32 KHz), maximum registration time 128 seconds max-AD
At PCM / 32 kHz, these values depend on the sampling and coding settings. The control method is to connect the CN 15 on the main control board 30A (main control means 30) and the P1 of the audio reproduction board 41A, and to register 12 channels.
At 0CH, the channel time is free size. The communication specifications are a communication baud rate of 4800/9600 bps, a stop bit of 1 bit, a data length of 8 bits, and no parity and an asynchronous system. As shown in FIG. 11, the CH2 communication port is used for signal line connection of data transfer communication, and the CN 15 on the main control board 30A and the audio reproduction board 4
Connect P1 of 1A. The control code / record data format corresponds to each code signal, data and content. For example, as shown in FIG. 12, data: 06h and contents: positive correspond to the signal: ACK. Further, as shown in FIG. 13, command / channel data has target data of a horizontal parity BCC, and a mark * in the figure of the horizontal parity BCC indicates a state change.

The communication protocol is as shown in FIG.
A predetermined procedure is followed between the CN 15 on the main control board 30A and the P1 on the audio reproduction board 41A. For example,
When the main control board 30A responds to the inquiry from the main control board 30A after power-on that the audio reproduction board 41A is reproducing or waiting, the main control board 30A determines the state. When the audio reproduction board 41A responds to the reproduction instruction from the main control board 30A that the reception is abnormal or normal, the main control board 30A performs retransmission when the reception is abnormal, but waits when the reception is normal. Alternatively, the reproduction is started on the audio reproduction board 41A side, and the next data is transmitted when the reproduction ends. Further, when the sound reproduction board 41A responds to the retransmission request with the previous transmission content, the main control board 30A determines the state, and in particular, for the forced stop, the sound stop is performed on the P1 side of the sound reproduction board 41A. Then, the main control board 30A performs the next process. In the voice operation, in order to reproduce the voice when the animation data and the text data are displayed, the condition is that the voice code data is recognized on the animation data in the animation data, and the voice command is transmitted in the text data. Condition. As a restriction on audio playback, for audio playback and display data synchronization, audio playback is started when the audio code is recognized, but the screen configuration is then adjusted on the display data side according to the audio playback time. We need to change it. As shown in FIG. 15, the configuration of the display setting section is such that the header content is stored in the header information section of the external memory 80. Here, the animation number, frame information, display priority,
The display repetition count and the voice code are stored.
As the frame information, the display frame number / second, the total frame number, the start frame position, and the next display animation number are stored. As display priority, setting 0: no display data, setting 1: animation priority display, setting 2: text priority display are stored, and as the audio code, setting 0: no audio code, setting 1 to 9999: audio The presence of a code is stored. Regarding the flow of animation data display, first check the presence of an external memory card when the power is turned on. If there is a memory card, obtain header information, and display animation display data (for example, 4 kilobytes per frame) and audio data. To display data and output audio.

If the display priority setting is 0 and there is no display priority, no data display is performed even if it is recognized that a memory card is inserted. That is, only text data can be displayed. If there is a display priority and there is an animation priority designation of setting 1, the animation data stored in the memory card is displayed. When the setting of the next display animation number is designated, after the display data for one title is displayed, the display data of the designated animation number is continuously displayed. With this setting, animation display can be repeated indefinitely. If the display priority is given and the text priority designation of setting 2 is given, the text data is displayed without displaying the animation data stored in the memory card. Animation display is performed only when it is set to display animation by communication. When the setting of the next display animation number has been designated, after the display data for one title has been displayed, the display data of the designated animation number is continuously displayed. With this setting, animation display can be repeated indefinitely.

With the above configuration, the voice synchronization operation in the case of animation data starts as shown in FIG.
Is determined (S2). If there is no voice code 39, the LED display unit 60 is turned on to display data (S2).
3). On the other hand, when the audio code 39 is present, the audio code is transferred to the audio reproduction board 41A (S4), the audio is output from the audio output unit 40 (S5), and the LED display of one frame data is performed (S6). As described above, the voice output unit 40 performs voice output when a voice code is recognized. The display of the one-frame data is repeated as long as the data display is not completed, and the process returns to the start if the display of the one-frame data is not completed. As shown in FIG. 17, the voice synchronizing operation for text data is started, first, a display code is received by host communication (S1), the presence or absence of the voice code 39 is determined (S2), and the voice code 39 is determined. LED when there is no reception
The display unit 60 is turned on to display data (S3). On the other hand, if there is a reception, the audio code 39 is transferred to the audio reproduction board 41A (S4), the audio is output (S5), and the LED display of the data is performed (S6). This display of the text data is repeated as long as the data display is not completed, and returns to the start when the data display is completed.

As described above, the present embodiment is not limited to simply displaying data, but also expresses voice in conjunction with animation moving images and text characters. Especially DP-RAM33
When data is transferred to the CPU, the data bus of the CPU 31 is thinned out and connected to pack 4 bytes of data into 1 byte. As a result, the amount of data transfer can be reduced to speed up the display processing, and the animation moving image can be displayed at high speed in real time. In the conventional method, animation video could be displayed only at 15 frames (screen) / sec.
High-speed display can be performed at 0 frames (screen) / second, and animation animation display of 12 lines can be performed.

[0018]

According to the present invention, it is possible to generate a sound linked to an animation moving image and a text character. Therefore, it is possible to arbitrarily select the animation moving image display and the sound generation linked to the animation and freely combine it with a conventional text character. As a result, the display expression is dramatically expanded, an accurate and accurate display notification can be made, and the display expression can be performed according to various usage purposes.
