Integrated network hard disk video recorder

Abstract

The invention relates to an integrated network hard disk video recorder, comprising a central control module, an audio / video processing module, a network support module, a plurality of functional expansion modules and a power control module, wherein, the central control module is a monolithic multimedia DSP processing chip which is internally provided with a double-speed memory, and is provided with a plurality of bus interfaces and functional expansion interfaces thereon, and is also provided with a display driving circuit. The display driving circuit is electrically connected with a touch screen display; a client can monitor multi-platform audio / video information through the touch screen display at the same time; the audio / video processing module, the network support module and the power control module are connected with the monolithic multimedia DSP processing chip through the bus interfaces or a network access technology; and the functional expansion modules are respectively connected with the monolithic multimedia DSP processing chip through the functional expansion interfaces corresponding to the functional expansion modules. The integrated network hard disk video recorder of the invention has simple hardware structure, high stability and low energy consumption, and lowers the cost, and the multi-platform monitoring at the same time can be realized by the client without an independent display drive.

Description

technical field [0001] The invention relates to the monitoring field, in particular to an integrated multifunctional network hard disk video recorder. Background technique [0002] With the progress of society, digitalization, networking and intelligence of video surveillance have become a development trend. The digital monitoring system has gradually entered the stage of large-scale commercial application, and the video monitoring system has also experienced three eras. [0003] First Generation: The Analog Era. Video is transmitted in analog over coaxial cable and processed analog by the control panel. [0004] The second generation: the semi-digital age. The video is transmitted by coaxial cable in analog mode, and digitally processed and stored by the multimedia control host or hard disk video recorder (DVR). [0005] The third generation: the all-digital age. Based on the network, with digital video processing technology as the core, a new type of digital monitorin...

AI Technical Summary

Problems solved by technology

[0008] At present, embedded hard disk video recorders mostly use multiple media processing chips or ASIC hardware coding chips plus some main control chips with weak processing capabilities to build products with equivalent functions. Large size, high cost, weak module coordination between chips, poor stability and high power consumption

On the other hand, it is difficult to realize the dual realization of remote control and local control in the field of monitoring
