Method and system for realizing video monitoring by mobile terminal supporting multimodes

Abstract

The invention discloses a method and a system for realizing video monitoring by a mobile terminal supporting multimodes. The method comprises the following steps: media transcoding equipment is configured with video transcoding parameters corresponding to various mobile network modes in advance; a mobile client side sends a request for the on-demand of a monitoring front-end to the media transcoding equipment directly or through a mobile streaming media relay; and the media transcoding equipment requests a fixed network streaming media server for media code stream of the monitoring front-end after receiving the request, transcodes and outputs the received media code stream. The method and the system can support the mobile client side with various mobile network modes to perform the on-demand of the monitoring front-end of the fixed network and extend the video monitoring of the fixed network to mobile video monitoring, thereby conforming to the megatrend of fixed-mobile convergence.

Description

technical field [0001] The present invention relates to the technical field of video monitoring, in particular to a method and system for realizing video monitoring by a mobile terminal supporting multiple network standards for fixed network and mobile integration. Background technique [0002] In recent years, IP technology has become a common network feature of all telecom networks, and fixed-line mobile convergence has also become a distinctive service feature of new service experience. The development of fixed network video surveillance is relatively mature and widely used. Mobile video surveillance service means that users can directly access PSTN / 2.5G / 2.75G / 3G / 4G and other public / wireless networks through various mobile or wired terminals (such as streaming media mobile phones, PDAs, PCs, etc.), and can monitor It is a fully digital mobile packet data service for real-time video monitoring of places and areas that you care about or care about. It mainly serves areas t...

Problems solved by technology

However, there are many mobile network standards at present, such as GPRS / TD-SCDMA / CDMA 1X / EVDO / WCDMA / WIFI, etc. The network bandwidths of various network standards that can be used for wireless Internet access are different. Some have high bandwidth and some have low bandwidth. Therefore, how the media transcoding device provides different media code stream conversion support for mobile terminals of different network standards is a technical problem that needs to be solved at present.

In addition, the current mobile users are not very clear about the network bandwidth they use, and may not understand some technical concepts such as resolution, bit rate, and encoding format. Mobile users do not provide resolution, bit rate, and other related parameters. In such a case, how the media transcoding device adapts to the bandwidth of different network standards and converts the code stream that conforms to the network standard is also a problem that needs to be solved
