Abstract

Disclosed is a system and method of data transmission/reception in which picture signals are encoded into image data, the attribute information of the image data is obtained, meta data are generated from the attribute information of the image data. The image data and the meta data are transmitted separately. With this system and method of data transmission/reception, when predetermined conditions are satisfied, i.e. only when a moving body is detected or abnormal data or data including significant information are detected, image data and meta data are transmitted. Therefore, since not all the data are transmitted, the amount of transmitted data is reduced. As a result, the amount of data accumulated in data recipient can be reduced and the load of data analysis operation can be alleviated. In addition, the burden on an operator visually monitoring image data can be eased. Furthermore, inadvertent failure in checking abnormal data or data including significant information can be prevented.

Claims

1. A data transmission/reception system having at least one data-transmitting terminal for transmitting data made of encoded picture signals and a data receiving-server for receiving the data the data-transmitting terminal has transmitted wherein

said data transmitting-terminal comprising:

an image processor for encoding externally supplied picture signals into image data and for generating attribute information of the image data;

a meta data processor for generating meta data from the attribute information of the image data supplied from said image processor; and

a communication unit for transmitting the image data supplied from said image processor and the meta data supplied from said data processor; and

said data-receiving server comprising;

a database for accumulating the image data and meta data received from said data transmitting-terminal;

a meta data analyzer for analyzing the meta data; and

a data display for displaying the image data and the meta data.

2. The data transmission/reception system as set forth in claim 1 wherein the image data is reproduced only when meta data satisfying predetermined conditions are detected by the meta data analysis in said meta data analyzer.

3. The data transmission/reception system as set forth in claim 1 wherein

said data-receiving server has a data searching unit for searching meta data accumulated in said database and reading out image data corresponding to the searched meta data;

and

said data display displays the image data read out by said data searching unit.

4. A data transmitting-terminal for transmitting data made of encoded picture signals comprising:

an image processor for encoding externally supplied picture signals into one of static image data and motion image data and for generating attribute information of the image data;

a meta data processor for generating meta data from the attribute information of the image data supplied from said image processor; and

a communication unit for transmitting the image data supplied from said image processor and the meta data supplied from said meta data processor.
