Embodiment Construction

[0031] Hereinafter, exemplary embodiments of the present invention are shown with reference to the accompanying drawings.

[0032] exist figure 1 Among them, the video sending devices 101a, 101b, 101c send the video data (as a data stream) acquired from the cameras to the video receiving device 102 in real time. While sending the video data, metadata in the video data is also sent. The video transmission device 101a, 101b, 101c may be a supervisory camera consisting only of hardware, or any terminal unit (for example, a personal computer, PDA (personal computer) equipped with software programs, image data input equipment, video data transmission equipment, etc. digital assistant) or mobile phone).

[0033] The video receiving device 102 receives video streams and metadata of the video streams transmitted in real time from the plurality of video transmitting devices 101a, 101b, and 101c, and stores these data. The video receiving device 102 can also be used to display the vi...

Abstract

In a video data transmitting method of sending in real-time video data being externally inputted, when encoding video data being inputted as stream data, start and stop of an encoding process is repeated at a predetermined time interval to carry out a data dividing process whereby a plurality of time-continuous video data are generated as partial video data. Also, metadata of partial video data is generated, which is sent, together with the partial video data, in real-time as partial video metadata.

Description

technical field [0001] The present invention relates to a video data transmission / reception method for transmitting / receiving video data and a video surveillance system. Background technique [0002] The goal of a video surveillance system is surveillance against intruders, and conventionally this system uses a slow speed VTR or similar. In tens of hours, the slow VTR can continuously record the video signal input from the camera frame by frame at constant intervals of several seconds to tens of seconds. [0003] In a slow VTR, there is a limit to the recording time as with analog video tape. Therefore, by performing video recording in a method of feeding frames, the recording time is increased. However, if, for example, recorded video images are used in a criminal investigation, it may sometimes be desirable not to have frames of a video feed, but a recording that has a high frame rate so that details of the intruder's behavior can be confirmed. [0004] Various known te...
