Abstract

The invention discloses a cascading video device and a data processing method thereof, and relates to the field of video monitoring. The cascading video device comprises a cascading video main unit (110), a cascading video auxiliary unit (120), a network interface (101), a PCI bus (102) and a BT1120 bus (103). The network interface (101), a cascading main CPU (113), the PCI bus (102), a cascading auxiliary CPU (123), the BT1120 bus (103) and the cascading main CPU (113) are connected in sequence. The cascading video device and the data processing method thereof have the advantages that the cascading video device has high reliability and is free of maintainability under the unattended situation and can process system faults in time, the device fault recovery time is shortened, and the timeliness and smoothness of decoded pictures of the cascading video device can be improved.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a cascaded video device and a data processing method thereof. Background technique [0002] With the rapid increase of network bandwidth and the development of front-end monitoring equipment towards digitalization and high-definition, higher requirements are put forward for the video processing capabilities of back-end network video monitoring equipment. Limited by the capability of a single video processing chip, the processing capability of traditional embedded network video processing equipment is relatively low, and cannot meet the market's requirements for high-definition video processing with a large number of channels. For this reason, multi-chip cascaded video equipment has become a hot research direction to solve this problem. [0003] Multi-chip cascaded video devices, that is, multiple embedded processing chips are cascaded together through PCI, BT1120 and other techni...
