DESCRIPTION OF THE PREFERRED EMBODIMENTS First, an outline of a still image transmission system of the present invention will be described with reference to FIG. In the figure, A is a host of the center corresponding to the transmission unit of this system, and is a still image transmission device. The still image transmission apparatus A is provided with a database 1 for recording a plurality of still image data 11, 12, 13, ...

The still image data referred to here is image data obtained by digitizing a painting or photograph as an original image by using an attached scanner, an RGB camera or the like. When the still image data is registered in the database 1, the data of the attribute representing the content of the still image is also registered using the keyboard or the like.

Here, as attribute data, the genre (landscape, person, still life, satire, ink, etc.) belonging to the still image work, the work name, the author's name, and the season associated with the work (spring,
Summer, autumn, winter), events related to the work (New Year, Tanabata, Hinamatsuri, Christmas, etc.). The still image data 11 shown in FIG. 1 is attached with data of attributes of landscape, winter, and Christmas, and the still image data 12 is attached with data of attributes of person, spring, and hinamatsuri.

In the figure, α is a control unit (corresponding to a transmission side control unit) which is a host computer. The control unit α controls the entire still image transmission apparatus A, and also controls the reading / writing of the database 1 and a memory 2 (corresponding to a receiving side memory) described later and the transceiver 3. In particular, the still image data 11 and the like on the database 1 are classified into channels ch1 to chn by using the attribute data, and the classified still image data 11 and the like are written in a predetermined address of the memory 2 in units of channels.

Here, ch1 is a landscape picture, ch2 is a still life picture, ch3 is an event ... chn is set to the season.
Since the still image data 11 has data of attributes such as landscape, winter, and Christmas, this data is ch1.
Be assigned to. Similarly, since the still image data 12 has data of attributes of person, spring, and hinamatsuri, this data is assigned to ch2.

Moreover, the control section α manages the transmission schedule of still image data. That is, if the date accessed from the still image display device B is Christmas time, the event of ch3 is the item of Christmas, chn.
Is automatically set to the item of winter, and as a result, the still image data 11 is distributed to ch3 and chn in addition to ch1. Similarly, if the date accessed from the still image display device B is the time of the Hinamatsuri, the event of ch3 is automatically set to the item of Hinamatsuri and chn is the item of spring, and as a result, the still image data 12 is other than ch2. To ch3
It is also distributed to chn.

Still image data 1 written in the memory 2
1 and the like are read out in channel units by access from the still image display device B described below, and are transmitted to the wired line 4 by the transceiver 3.

In order to reduce the capacity of the memory 2, the data is updated every time the transmission of still image data in units of channels is completed. For example, when the still image data 11 of ch1 is read and the transmission by the transmitter / receiver 3 is completed, the next still image data of ch1 is written in the memory 2 to update the content of the data. The same applies to other channels.

In the figure, B is a terminal connected to the wired line 4 corresponding to the receiving section of this system, and is a still image display device arranged on the user side. However, the illustration of the other still image display device B is omitted.

The still image display device B is provided with a display 8 for displaying and outputting a still image, and also with a channel changeover switch 9 for setting a still image channel. Reference numeral 7 denotes a control unit (corresponding to a reception side control unit) which is a computer on the terminal side.

The still image data transmitted via the wired line 4 is received by the transmitter / receiver 5 and is stored in the memory 6 (memory on the receiving side).
It is recorded at a predetermined address at any time. The control of reading from the memory 6 is performed by the control unit 7. The still image data read from the memory 6 is output to the display 8 as needed.
A still image is displayed and output on the display 8 based on the still image data.

For example, when ch1 still image data is recorded in the memory 6, a landscape image is displayed and output on the display unit 8. Moreover, on the screen, several pieces of still image data are prepared, and the timer function of the control unit 7 determines the time interval and sequentially reads the data, so that the display unit 8 displays each time a predetermined time elapses. The output landscape image automatically switches to another one. The attribute data (for example, work name, author name) is also displayed and output on the display unit 8.

The control unit 7 has the following functions in addition to the function of sequentially reading out still image data on the memory 6. That is, the setting of the channel changeover switch 9 is constantly monitored, and when the setting is changed, the still image transmission device A is accessed each time, the still image data on the memory 2 is read out, and the still image display device B is read. It is transferred and written in the memory 6. With this function, the still image of the channel set on the channel changeover switch 9 is displayed and output on the display unit 8.

For example, if the setting of the channel changeover switch 9 is changed from ch1 to ch2, the still image data of ch2 is transferred from the transmitter A to the still image display device B,
The contents of the memory 6 are updated, and as a result, the display output of the display 8 is switched from the ch1 landscape image to the ch2 still life image.

In the case of the still image transmission system having the above-mentioned structure, it is possible to freely select a still image of a desired genre by operating the channel changeover switch 9 of the still image display device B. Even though it is an electronic painting, it is possible to enjoy a wide variety of paintings and the like, and it is possible to match the mood of the user at that time and the atmosphere of the room.

In particular, since the still image transmission apparatus A manages the transmission schedule of the still image data as described above,
When the channel changeover switch 9 is set to ch3 or chn, it is possible to enjoy a still image according to the event and the season at that time, and it is possible to perform an environment production completely different from the conventional one.

It is of course possible to use a digital communication network such as ISDN as the wired line 4, but if the existing wired line that has been used in general households is used, this new system can be spread immediately. It is expected that a new business will be created along with this.

A specific example of the still image transmission apparatus A will be described below with reference to the drawings. FIG. 2 is a configuration diagram of the still image transmission apparatus A.

Reference numeral α1 is a host computer for reading and writing still image data on the database 1 and outputting the read still image data to the transceiver 3 which is a multiplex transmission device via the built-in memory 2. Has become. The transceiver 3 has a function of simultaneously transmitting still image data of a plurality of channels.

Subcomputers α2 and α3 are connected to the host computer α1. A control unit α is composed of the host computer α1 and the sub computers α2 and α3. The sub computer α2 is a dedicated terminal device for setting a transmission schedule of still image data. On the other hand, the sub computer α3 is a dedicated terminal device for creating still image data. Sub computer α3
An input device α4 such as a scanner or an RGB camera is connected to the.

Next, a procedure for creating new still image data will be described with reference to FIG.

An operator operates the sub computer α3 to start a program for creating new data, and sets a still image document on the input device α4. Then, it is confirmed whether or not the original of the still image is normally taken in, and then the input of the attribute data is awaited. Then, the operator inputs the attribute data, the title of the still image data, etc. by using the mouse or keyboard of the sub computer α3. When it is confirmed that all the items have been input, the attribute data is sent to the sub computer α for the operator to reconfirm.
3 Display on the display.

When the operator confirms the reconfirmation, the program is started to register the still image data in the database 1 together with the attribute data. As a result, the host computer α1 operates to add the data of the registration date and then register the still image data and the attribute data in the database 1. At the same time, the title of the still image data is registered in the attribute-based file on the database 1. The attribute-based file is a list file of titles of still image data.

For example, when still image data is attached with data of attributes such as landscape and autumn, there are an attribute-based file that manages only landscape images and an attribute-based file that manages only autumn pictures. Titles are registered respectively.

The above-described processing is repeated to record a plurality of still image data on the database 1. This completes the program for creating new data.

It should be noted that attribute-specific files and channel ch1
Since there is a one-to-one correspondence with ~ chn, still image data and the like on the database 1 are also classified into channels ch1 to chn using this attribute-specific file.

Next, the procedure for setting the transmission schedule of still image data will be described with reference to FIG. The operator operates the sub computer α2 to start a program for setting a transmission schedule.

First, the input of a channel number and a year and month to be scheduled is awaited. When the operator inputs these data using the mouse or keyboard of the sub computer α2, the schedule setting screen is displayed on the display of the sub computer α2. At the same time, at the end of this screen, a list of files by attribute of the input channels is displayed as a sub-window, after which the system waits for the input of the date on which the schedule should be set. Data entry of the date is done by the operator moving the cursor to the date on which he wants to schedule and pressing the ENTER key.

When it is confirmed that the ENTER key has been pressed, the cursor is moved to the sub-window displaying the list of files classified by attribute, and thereafter, data input of the priority order of still image data transmission is awaited. That is, when the operator moves the cursor to the title to be transmitted first on the day and presses the ENTER key, the title is entered in the transmission data name field for that date. After that,
Similar to the above, the cursor is moved to the second, third ... Nth and the ENTER key is pressed to determine the priority order. When the nth number is entered, the cursor automatically returns to the date selection window.

When all the settings are completed in this way,
The contents of these settings are registered as a schedule file in the database 1 for each channel. This completes the program for setting the transmission schedule.

Next, a program for transmitting still image data will be described with reference to FIG. First,
The schedule file of each channel on the day is read from the database 1. Then, when the still image data of a certain channel is requested by the access from the still image display device B, the still image data is sequentially read from the database 1 according to the contents of the schedule file of the channel and is also built in the transceiver 3. The standby memory and the transmission memory are sequentially written, and are sequentially transmitted to the still image display device B. The same is true when another channel is requested, and this process is repeated thereafter.

On the next day, the schedule files of the channels on the next day are read from the database 1 and the same processing is performed.

With such a program, the transmission schedule management of the still image data is performed, and as a result, the still image display device B also outputs the still image according to the schedule setting.

Next, a specific example of the still image display device B will be described with reference to the drawings. FIG. 6 is a schematic configuration diagram of the still image display device B.

In this case, the still picture display device B is a single master unit B.
1 and n slave units B2 to Bn, and a liquid crystal display mounted on the master unit B1 or the slave units B2 to Bn only by operating a channel changeover switch 9 or the like provided on the master unit B1. The channels of the displays 81 to 8n can be switched.
