Problems solved by technology

SDI technology uses a special SDI interface at the front end, and uses an optical transceiver for long-distance transmission. Although it can reduce the image encoding and decoding delay, the hardware requirements are too high and the cost is also high. Large-scale commercial deployment will encounter big obstacle

Embodiment Construction

[0020] In the present invention, firstly, the encoding process is abandoned in the monitoring front-end equipment, so that when the back-end receives it, the decoding process is correspondingly unnecessary. This idea can solve the problem of large delay introduced by encoding and decoding. Because the data has not been encoded, taking the 720P image as an example, if it has not been encoded, the data transmission volume per second will reach more than 600Mb, which will cause more pressure on the CPU of the monitoring front-end equipment than the encoded situation. Several times or even dozens of times, because the encapsulation of IP packets is usually completed by the CPU. At this time, the monitoring front-end equipment needs to adopt a CPU with more powerful processing capability, which leads to an increase in cost. Due to the large number of monitoring front-end equipment deployed, a few percent increase in cost may cause a high cost increase in quantity. Therefore, it is...

Abstract

The invention provides monitoring front-end equipment applied to a video monitoring system. The equipment comprises an analog interface, an analog-to-digital conversion (ADC) module and a two-layer packaging module, wherein the analog interface is connected to a front-end multi-media collecting device of a video monitoring system and used for receiving analog multi-media signals sent by the multi-media collecting device, the ADC module is connected with the analog interface and used for converting the analog multi-media signals into multi-media digital signals serving as source data, and the two-layer packaging module is connected with the ADC module and used for packaging the source data output by an ADC unit and without coding and IP packaging in Ethernet messages and sending the source data out through the Ethernet. The invention further provides an encoding server matched with the monitoring front-end equipment. The monitoring front-end equipment and the encoding server solve the problem of severe transmission delay of the video monitoring system in the prior art with reasonable cost and capable of being effectively compatible with the existing various video monitoring technologies in many preferable modes of execution.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a monitoring front-end device with a new architecture and an encoding server serving the monitoring front-end device. Background technique [0002] Compared with the traditional analog video surveillance solution, the current IP video surveillance system has made great progress in many aspects, and has huge advantages over traditional analog surveillance in terms of large-scale networking, massive data management, and long-distance transmission. . However, compared with traditional analog surveillance, IP video surveillance technology also has deficiencies, among which the disadvantages in image delay are obvious. At present, the image delay with very good effect can reach about 150 milliseconds, compared with the image delay of less than 50 milliseconds in traditional analog monitoring, there is still a gap of more than 100 milliseconds. The main reason is that there is a proce...
