Abstract

PURPOSE:To reduce the trouble of recording processing of data and a operation mistake by generating write control information to a data receiver in response to transmission data, synthesizing the write control information and a transmission data and sending the result. CONSTITUTION:The data transmitter 1 consists of a data input section 11, a control section 12 and a data transmission section 14. Write control information 104 to a data receiver 2 is generated in response to the input data 101 desired to be sent. The information 104 and the transmission data 102 are synthesized and sent to the receiver 2. Then the right of write control executed so far in the receiver 2 is transferred to the transmitter 1 and the write control to a data storage device 3 is realized directly from the transmitter 1. Thus, the trouble of the recording processing of the data and the operation mistake in the receiver 2 are reduced.

Description

TECHNICAL FIELD The present invention relates to a data transmitting device, and more particularly to a data transmitting device that transmits transmission data in a data communication system.

Prior Art Conventionally, in a data communication system, transmission data transmitted from a data transmission device is received by a data reception device, and the received transmission data is recorded in the data reception device. Write control had to be performed manually one by one. Furthermore, in some cases, it is necessary for the data receiving device to manage what kind of write control is performed for each piece of write data during recording.

In such conventional data communication systems, it is necessary to manually control data writing one by one in the data receiving device, which makes the data recording process complicated.
The drawback is that there is a concern about operational errors.

In addition, if it is necessary to collectively manage the write control performed for each piece of write data during recording, the data receiving device can be individually equipped with a function for collectively managing the write control information group. This has the disadvantage of complicating the mechanism of the data receiving device.

OBJECTS OF THE INVENTION The present invention has been made to eliminate the drawbacks of the conventional ones as described above, and can reduce the complexity and operational errors of data recording processing in a data receiving device. To reduce the burden on a data receiving device by omitting a function for collectively managing a group of write control information when it is necessary to collectively manage write control performed on each piece of write data. The purpose is to provide a data transmitting device that can perform

Composition of the Invention A data transmitting device of the present invention is a data transmitting device for a data communication system including a data transmitting device that transmits transmission data, and a data receiving device that receives and stores the transmission data, wherein the data transmission device transmits the transmission data. The present invention is characterized in that it includes a generating means for generating write control information to the data receiving apparatus in accordance with the data receiving apparatus, and a transmitting means for combining the transmission data and the write control information and transmitting the synthesized data to the data receiving apparatus.

Embodiment Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. In the figure, a data communication system according to an embodiment of the present invention is comprised of a data transmitting device 1, a data receiving device 2, and a data record holder 3.

The data transmitting device 1 includes a data input section 11, a control section 12, a write control status management file 13, and a data transmitting section 1.
4 and an antenna 15. The data receiving device 2 also includes an antenna 21 and a day/evening receiving section 22.
and a control section 23.

The data input unit 11 converts input data 101 to be transmitted into transmission data 102 and sends it to the data transmission unit 14, and also inputs information necessary for the control unit 12 into the input data 102.
01 and output to the control unit 12 as transmission data accompanying information 103.

The control unit 12 inputs the transmission data accompanying information 103,
Write control information 104 for controlling data writing to the data record holder 3 is generated and outputted to the data transmitter 14.

When generating the write control information 104, the control unit 12 exchanges a write control status identification signal 105 with the write control status management file 13 that stores the write control status in the data receiving bag @2. Further, the control unit 12 generates the write control information 104 in response to an auxiliary control signal 106 manually operated from the outside.

The data transmitting unit 14 combines the transmitted data 102 from the data input unit 11 and the write control information 104 from the control unit 12 to generate a transmitted signal 107, and transmits this to the data receiving device 2 via the antenna 15. .

The data receiving device 2 receives the transmission signal 1 from the data transmitting device 1.
07 via the antenna 21, and the data receiving unit 22
decomposes this transmission signal 107 into write data 108 and write control information 109, and sends them to the data record holder 3 and the control section 23, respectively.

The control unit 23 performs write control to the data record holder 3 (for example, control to specify a write position inside the data record holder 3) via the interface 110 based on the input of the write control information 109, and maintains the data record. In the device 3, write data 108 is written by this write control.

In this way, the write control information 104 to the data receiving device 2 is generated according to the input data 101 to be transmitted, and the write control information 104 and the transmission data 102 are combined and sent to the data receiving device 2. By this,
The write control authority, which was conventionally performed by the data receiving device 2, can be delegated to the data transmitting device 1, and writing control to the data record holder 3 can be directly realized from the data transmitting device 1. The complexity of data recording processing and operational errors can be reduced.

In addition, when it is necessary to collectively manage the write control performed on each piece of write data 108 during recording, the data transmitting device 1 can manage these write control information groups collectively, so it is possible to It becomes possible to omit the function for collectively managing the write control information group that was required for the data receiving device 2, and the burden on the data receiving device 2 can be reduced.

In one embodiment of the present invention, the data record holder 3 is provided outside the data receiver 2;
It is clear that the same operation can be performed even if it is provided inside the data receiving device 2.

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, write control information to be sent to a data receiving device is generated in accordance with transmitted data, and the write control information and the transmitted data are combined and sent to the data receiving device. By doing so, it is possible to reduce the complexity of data recording processing and operational errors in the data receiving device, and it is necessary to collectively manage the write control performed for each piece of write data during recording. This has the effect that the load on the data receiving device can be reduced by omitting a function for collectively managing a group of write control information.
