Description

Dual bus based monitoring system and method thereof

The present invention generally relates to monitoring systems and methods for data transmission. More specifically, the present invention relates to a dual bus based monitoring system and method for data transmission. Background technique

At present, there are two main types of monitoring systems for video switching, one is analog switching. The simulation matrix is stable in operation, simple in operation, low in cost, less in delay, and large in capacity. The shortcomings of the analog matrix: First, the signal is unstable, because the monitoring system is now multi-level networking, and the weakness of the analog matrix is that the more the cascade, the weaker the signal, so it is inevitable to damage the signal through several levels of networking; The wiring is complicated and unfavorable. Nowadays, the monitoring project is getting larger and larger. Under this development trend, if the traditional analog matrix will inevitably encounter complex wiring and large-scale matrix groups, this will make the original large-scale system more complicated. And it is not conducive to later maintenance and management. Finally, network management and remote monitoring are not possible.

Another monitoring system that implements video switching is the Ethernet-based "digital matrix." Currently monitoring most of the "digital matrix, the products are based on Ethernet" network matrix,. Different from the traditional analog matrix, the "network matrix" is a module that adds code transmission based on the original analog matrix. This module is also called video encoder. The remote client software or monitoring center software can connect the code of the matrix through software. Module, the networking of the matrix. Through the network, full control of the matrix or partial authority control can be realized, so that the higher-level department can centrally manage and control the lower-level departments. However, in order to control the bandwidth of digital video for real-time transmission in an Ethernet network, the network matrix must use video compression coding technology. Although the video compression coding technology represented by MPEG-4 and H.264 has been able to achieve better picture quality under lower video bandwidth, the image effect after video coding is still obvious compared with analog video. The gap, and because of the need to encode, network transmission, and then decode the display, it will generate a large delay.

It can be seen that the analog matrix is used in the monitoring system of the analog matrix, and the encoding, storage, decoding, and video processing are required to be implemented by the DVR, the DVS, and the corresponding decoder, and the analog matrix cannot be managed through the network. As a result, the entire video surveillance system is costly, difficult to maintain, and has poor scalability. The "digital matrix" monitoring system based on Ethernet can solve the above problems well. However, Ethernet-based "digital matrix" analog switching, due to Ethernet bandwidth limitations, must be compressed before the analog switching, then transmitted through the network, and finally decoded on the wall display. This process introduces two problems for analog switching: (1) Since the analog input needs to be compressed before switching, the compressed video data is decoded before display, which leads to video quality degradation; (2) the whole The switching process must go through three processes of encoding, network transmission and decoding, which will increase the delay of switching.
