Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing:

[0021] like figure 1 As shown, a control method for a multi-channel high-definition decoder cluster specifically includes:

[0022] (1) Use the multicast UDP data packet as the communication method between the control logics of the multi-channel high-definition decoder; the multicast UDP data packet includes the target port and the cluster number.

[0023] The communication among the main control logics of multi-channel high-definition decoders is realized by multicast UDP packets. In practice, how to use the cluster function is determined by the user. The number of devices in the cluster is uncertain, so the connection-oriented TCP solution is not applicable. It will be very complicated to use, and the number of communication packets will be large. It will add a lot of load to the network. In principle, it presents higher complexity and inapplicability. However, ordina...

Abstract

The invention provides a control method for a multipath high-definition decoder cluster, and the method specifically comprises the following three parts: (1), employing a multicast UDP data package to serve as a method for communication among all control logics of multiple high-definition decoders, wherein the multicast UDP data package comprises a target port and a cluster number; (2), employing an IP and an MAC address as the identification, and determining the priority of all control logics during the internal communication of multiple high-definition decoders through the adding sequence of a user; (3), employing an election method as a method for detecting a unique main control logic during the communication of all control logics of the multipath high-definition decoder cluster. According to the invention, one main control logic is selected from the multipath high-definition decoder cluster, so as to coordinate the conflict among all control logics, and to prevent the control disorder between equipment.

Description

technical field [0001] The invention relates to the fields of safety protection and video monitoring, and relates to the cluster technology of multi-channel high-definition decoder equipment with digital video decoding as the core function. Background technique [0002] The multi-channel high-definition decoder is a decoding device specially designed for the deployment and management of high-definition surveillance systems. The operation is stable and reliable, and it supports a variety of high-definition display interfaces. It is an ideal device for displaying high-definition network video signals on the wall in the monitoring center. [0003] As the monitoring center's demand for multi-physical screen splicing becomes more and more vigorous, it is imperative to continuously break through the upper limit of physical screen splicing. The technical difficulty that must be solved to break through the upper limit of physical screen splicing lies in the multi-device cluster tec...
