Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] The core of the present invention is: the present invention adds a data compression dump device in the audio-video monitoring system: the audio-video data is converted and compressed into low-bit-rate encoding format data and then written into the storage subsystem, thus reducing the occupation of audio-video data storage space to reduce monitoring costs. The data compression dumper can be a server, or a device integrated in the data compression dump service program. In addition, the data compression dumper can back up the audio and video data from the storage subsystem according to the preset dump plan, and then compress it according to the preset conversion compression rules and rewrite it into the storage subsystem, and modify the corresponding Index and delete the original saved uncompressed audio and video data. The data compression dump can also compre...

Abstract

The invention relates to a voice / video detecting system. Wherein, it adds one data compression memory in present voice-video detecting system; converts and compresses the voice and video data into low-code-rate coding format data to be written into memory subsystem; therefore, it can reduce the memory space of voice and video data, to reduce the detecting cost. The data compression memory can be one server or the device mounted with data compression memory service program. In addition, the data compression memory can backup voice and video data from the memory subsystem via preset memory plan, and via preset compression rule to compress and write into memory subsystem, to modify relative index and delete stored voice and video data not compressed.

Description

technical field [0001] The invention relates to the field of video processing, in particular to an audio and video monitoring system and a data compression dumper. Background technique [0002] With the increasing popularity of network applications, the use of network monitoring has become the driving force of development. Taking audio and video surveillance as an example, users can implement audio and video surveillance with high performance and simple configuration in the existing IP network environment. Please refer to FIG. 1 , which is a schematic structural diagram of an existing audio and video monitoring system. It includes a signal collector 11, an encoder 12 for digitizing the collected audio and video data, a decoder 13 for converting digital signals into analog signals, a storage subsystem 15 for storing data, and a real-time A real-time monitoring subsystem 14 for playing audio and video data and a playback subsystem 16 for playing back audio and video data. ...
