Open type multimedia transmission system based on internet and streaming media technique

Abstract

The invention provides an Internet and streaming media-based open multimedia transmission system, comprising a central service platform and a fore end coding / decoding device connected with the central service platform and collecting video, audio and alarm information and the like, as well as client ends for browsing and controlling far-end video, audio and alarm information and the like and the system, and the central service platform comprises ten subsystems of: platform management subsystem, control service subsystem, alarm service subsystem, scheduling subsystem, AAA service subsystem, service management subsystem, fore end application subsystem, storage subsystem, distributing subsystem (VIDU), and client end application subsystem. And it can make centralized or scattered networking according to the number of information collection points, where the scattered network physically differentiates the above ten subsystems and reasonably allocates network resources. And it can be applied in safeguarding and monitoring field and also in the fields of traffic control, remote education, remote medical treatment and e-commerce.

Description

technical field [0001] The present invention relates to a system and method for transmitting multimedia information on the Internet, especially adopting MPEG-4 video and audio codec technology and streaming media technology to transmit multimedia information (image, voice, data and other comprehensive information) in real time to realize digital intelligent monitoring systems and methods. Background technique [0002] Video surveillance technology has experienced the development process from analog surveillance to digital surveillance and network surveillance. The "first generation" analog monitoring system is completely realized by analog signals. It uses traditional video recorders to store information through tapes. The information is not easy to store for a long time, the information storage is small, data security cannot be guaranteed, and the system cannot be expanded due to geographical restrictions. [0003] The "second generation" digital surveillance system is mai...

AI Technical Summary

Problems solved by technology

[0004] 1. It adopts JPEG and MPEG-2 compression methods, which are not suitable for transmission on the Internet;

[0005] 2. Each "hard disk video recorder" is an independent body, and it is difficult to connect to the Internet. After the transformation of the network, it is often necessary to realize point-to-point connection through a private network, and it is impossible to build a large-scale cross-regional network system;

[0006] 3. The multimedia transmission realized by the hard disk video recorder through network transformation simply includes video and audio, and the audio is only collected in one direction, and the back-end cannot realize real-time two-way voice intercom with the front-end

[0007] 4. The current network monitoring systems are relatively closed systems, and the devices of various manufacturers are not compatible. There is no concept of a unified access platform in the system architecture, causing many users to repeat investment in building the system in stages, which cannot effectively protect the original have investment

[0008] 5. The current network monitoring system is generally poor in openness and can only be used as an independent monitoring system

The system does not provide relevant SDK development interfaces, and cannot be integrated with the user's MIS system

The scope of application of the system is therefore limited

[0009] At present, the architecture of similar systems in the industry is client / server mode, and the front-end encoding device or DVR acts as a network access server at the same time. Such a simple architecture method cannot build a large-scale application system.
