    • 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.
    • 公开了将图像信号编码为图像数据的数据发送/接收的系统和方法,获得图像数据的属性信息,从图像数据的属性信息生成元数据。 图像数据和元数据被单独传送。 利用该系统和数据发送/接收方法,当满足预定条件时,即仅当检测到移动体或检测到包括有效信息的异常数据或数据时,发送图像数据和元数据。 因此,由于不是全部数据被发送,所以发送数据的数量被减少。 结果,可以减少在数据接收者中累积的数据量,并且可以减轻数据分析操作的负担。 另外,操作者视觉上监视图像数据的负担可以减轻。 此外,可以防止检查异常数据或包括重要信息的数据无意中失败。
