US 7,678,236 B2 · System and method of data transmission/reception

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.

Dependent claims

A data transmitting-terminal for transmitting data made of encoded picture signals to a data receiving server, the data receiving server connecting to a plurality of data transmitting-terminals, the data transmitting-terminal comprising:

an image processor for encoding externally supplied picture signals and generating one of static image data and motion image data and for processing image analysis using the generated image data and for generating attribute information of the image data including a result of the image analysis;
a meta data processor for generating meta data from the attribute information of the image data supplied from said image processor sequentially to a process of the image processor;
and
a communication unit for transmitting the meta data supplied from said meta data processor and then transmitting the image data supplied from said image processor only when the following predetermined conditions are satisfied to reduce a load of the data receiving server:
a) a predetermined time interval has elapsed, or a result of the image analysis identifies an object of interest, and
b) a permission of data transmission is given by a data-receiving server in response to a transmission request by the data transmitting terminal.
