Description

Technical Field [0001] The present invention relates to a media moving method and system for monitoring an emergency situation,

The present invention relates to a media moving technology for providing a situation of a scene changing every moment by moving an image of a scene to a mobile device on the spot when an emergency situation occurs in an in-building monitoring system, Based on network information including video information and bandwidth, transmission delay, jitter, RSSI, etc., including device information including device resolution, bit rate, frame rate and video resolution, To a media moving method and system.

Moving the media to the mobile device and monitoring it can be seen as one of the multi-screen technologies. Multi-screen technology is becoming increasingly popular as the number of devices that can play content increases, and the demand for seamlessly reproducing the same content that they own, on multiple devices. Multi-screen technology is a technology that seamlessly reproduces a single piece of content on TVs, cell phones, and PCs, and is seen as a fusion of content into a kind of network technology. This allows free content sharing and use among multiple screens.

With multi-screen technology, Internet operators can build a platform to advance into the mobile TV market based on their competitiveness in PCs. Broadcasters will be able to expand online distribution channels by providing differentiated contents and services to their users. . In addition, device vendors can expand their business models from hardware to service platforms to drive hardware strategies. For example, the security surveillance control service can share images in various devices by integrating multi-screen technology into existing methods of monitoring images taken by CCTV cameras through multi-vision.

However, the conventional multi-screen technology does not consider a content transmission method for each device that reproduces contents. That is, in order to provide the same quality of content among the screens in a case where a plurality of devices having different performance are connected to various networks, it is necessary to adjust the bit rate and resolution of the content adaptively according to the characteristics of the device and the network condition .
