Abstract

The invention discloses a digital video recorder with a multiprocessor cluster and a realization method of the digital video recorder. Data communication and exchange are carried out among multiple CPUs via a PCIE interface switch chip; each CPU is connected with the PCIE interface switch chip and a route or gateway function device to obtain a multimedia data code stream according to the network bandwidth and the IPC access way distributed by the route or gateway function device and process the multimedia data code stream, and processing of the multimedia data code stream includes at least one selected from decoding, storing, sending, display and output, replay, preview and intelligent analysis; and the route or gateway function device is connected with the multiple CPUs to distribute the network bandwidth and the IPC access way for the CPUs. According to the technical scheme provided by the invention, the CPUs are prevented from load imbalance and resource waste, the power consumption is reduced, the cost is reduced, and the using performance of products is improved.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a multi-processor cluster digital hard disk video recorder and its implementation method. Background technique [0002] A Network Video Recorder (NVR for short) is used to receive and process video signals in digital format. NVR, as the back-end node in the network-based security monitoring system, receives the digital video stream transmitted by the network camera (IPC) equipment through the network, and stores and manages it, so as to realize the advantages of the distributed architecture brought by the network. [0003] Existing mid-to-high-end NVR solutions are usually implemented in the following two ways: [0004] Mode 1, master-slave mode, a central processing unit (CPU) as the master control CPU, connects one or more CPUs responsible for audio and video processing such as decoding through peripheral component interconnection standard expansion (PCI-Express, hereinafter re...
