Abstract

PURPOSE:To attain automatic file system and to eliminate human intermediation by transmitting picture data and other additional data showing the atribute of a picture to be transmitted in the transmitting part, and by providing a picture memory to store the picture data and an atribute data memory to store the atribute data in the receiving part. CONSTITUTION:A control signal to confirm an atribute data about the picture data to be stored (for instance data of the kind of picture, date, transmission place, local code, serial number of sheets to be transmitted etc.), start of transmission, and standy state on the receiving part, etc. is inputted/outputted in/from a terminal 12. The atribute data is transmitted prior to the picture data that is transmitted from a transmission controlling part 4, or transmitted after the transmission of the picture data ends. In the receiving part, a demodulated data signal is separated into the picture data and the atribute data by a transmission controlling part 21, and the picture data is series-to-parallel-converted and stored in a picture memory 22 in form of a parallel data, while the atribute data is stored in an atribute data memory 25 in every word unit remaining in form of a serial data or punctuated on word unit.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a so-called still image transmission device that transmits an image signal such as a television signal through a narrowband transmission line such as a telephone line.

[Conventional technology]

Conventionally, this stationary W image transmission device has only the function of simply transmitting images, and when recording the image received at the receiving point to a magnetic disk or VTI (etc. In this case, the comments related to the received image are managed by the entire file function, or the comments are superimposed on the transmitted image and transmitted to the receiving point.

[Problem that the invention seeks to solve]

Such conventional still image transmission devices require human intervention to manage files at the receiving point, and automatically file and edit received image data. Things were impossible.

SUMMARY OF THE INVENTION An object of the present invention is to solve these problems and provide a still image transmission device that enables an automatic file system and eliminates the need for human intervention.

[Failure to solve the problem]

The configuration of the present invention is that in a still image transmission device that transmits an image signal via a narrowband transmission line of a telephone circuit, a mapped image data frame that indicates attributes of an image to be transmitted separately from image data is provided to a transmitter. The receiving section includes a transmission control means for transmitting data to the receiving side, and the receiving section has a receiving section that distinguishes between the image data and the Mil attribute data. l1lJ cape means, attribute memory means for accumulating the differentiated attribute data, image storage means for accumulating one or more sets of received image data, It is characterized by comprising input/output control means for reading out attribute data and the image data.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIGS. 1 and 2 are block diagrams of a transmitting section and a receiving section according to an embodiment of the present invention. 1. As the 11th part, the 1st
In the figure, the video signal input from terminal 10 is A/
The analog signal is converted into a digital signal by the D converter 1 and stored in the image memory 2 as image data.

The address control unit 3 is a part that generates pulses necessary for reading and writing image data into the image memory 2. The image data stored in the image memory 2 undergoes parallel-serial conversion in the transmission control section 4, is inputted as serial data to the modem 5, is subjected to phase modulation or phase amplitude modulation, etc. in the modem 5, and is sent to the terminal 11. It is sent out to a narrowband transmission path such as a telephone line, which is followed by a telephone circuit.

On the other hand, from the terminal 12, attribute data regarding the image data to be accumulated (for example, the year, month, and year of the image) is sent.

Control signals are input and output to confirm the sending location, area code, serial number in the number of transmitted sheets, etc.), the start of transmission, and the standby state of the receiving side. This attribute data is sent by the transmission control section 4 before the image data is transmitted, or after the image data transmission is completed. Further, the functions of this control signal include giving a read start command to the address control section 3, and an answerback that can be sent from the transmission control section 4.

Next, as a receiving section, as shown in FIG.
The received signal is "1" at the modem 20.

It is demodulated into a data signal indicated by "0". This data signal is divided into image data and attribute data by the transmission control unit 21, and the image data is stored in the image memory 22 as serial and parallel data, and the attribute data is stored in the image memory 22 as serial data or word by word. The data is divided into words and stored in the attribute data memory 2-5. 8t of these image memory 22 and attribute data memory 25 are
The capacity should be the same as or greater than that of GT, but it depends on the system used. Taniya@kimemory 2
The image data and attribute data stored in the 2 and attribute data memory 25 are accessed by the I10 control unit 26 at any time by a control signal from the host computer or controller connected to the terminal 31, and the attribute data is The attribute data accumulated in the memory 25 is output from the terminal 31 to the host computer or controller via the I10 control section 26, and the image data transferred to the image memory 22 is outputted to the D/2.
The digital signal is converted into an analog signal in the Ai converter 24 and outputted from the terminal 32.

〔Effect of the invention〕

As explained above, according to the present invention, the transmitting IM section transmits the image data with attribute data indicating the attributes of the image to be transmitted added, and the receiving section 1g transmits the image data. One composition that stores multiple sets of phantom memories and attribute data★One composition that stores multiple sets of attribute data memories,
By reading the attribute data from an external device such as a host computer, the receiving side can read and file the image data corresponding to the attribute data at any time using a management method based on the attribute data. This has the effect of allowing automatic file system construction without going through the .
