Problems solved by technology
[0006] For the video wheel cutting realized by the matrix device, there are mainly the following problems: 1. It is easy to cause interruption, jitter, mosaic, glitch and smearing of the monitoring image; 2. It may cause network congestion when multiple users access the same monitoring terminal ;3. Generally, a client can only perform 16-channel video rotation at most; 4. The cost of the entire monitoring system will increase due to the introduction of matrix equipment

Embodiment Construction
[0060] Refer to the accompanying drawings in the manual Figure 4 , to introduce in detail the multicast-based round cutting device provided by the present invention.
[0061] The information of the encoding terminal and the decoding terminal in the same multicast network is recorded on the wheel switching device; it is used to receive the configuration information packet of the wheel switching plan, and analyze and process the configuration information packet to obtain the parameters of the wheel switching plan After setting, according to the parameter setting, an instruction is issued to the encoding terminal set in the round cut plan and the decoding terminal set in the round cut plan to execute the round cut plan.
[0062] like Figure 4 As shown, the wheel cutting device includes:
[0063] Figure 4 The receiving module shown is configured to receive the configuration information package of the round cut plan;
[0064] Figure 4 The analysis module shown is used to a...

The invention relates to a multicast-based turning device, comprising receiving module, resolving module and instruction module; and a multicast-based turning system, comprising multicast network, coding terminal, decoding terminal, client end and management server, where the management server comprises the multicast-based turning device, recording the information about the coding terminal and the decoding terminal, receiving turning plan configuration information packet sent by client end and resolving and processing the configuration information packet and obtaining parameter settings of the turning plan and sending instruction to the coding terminal and decoding terminal to execute the turning plan; and the multicast-based turning method. And it implements multicast-based turning technique, increasing turning number and raising turning quality.
Description
technical field [0001] The present invention relates to a wheel cutting device, system and method, more specifically, the present invention relates to a multicast-based wheel cutting device, a multicast-based wheel cutting system including the wheel cutting device, and applications to the wheel cutting system Multicast-based round-robin method. Background technique [0002] With the increasing popularity of broadband network technology and the development of digital technology, video surveillance technology is developing towards large-scale network surveillance after analog surveillance and digital surveillance: video data encoded and compressed through local area network, wide area network, wireless network, or In other ways, it can be transmitted to any place where the network can extend, and the user can monitor and manage in real time only through the computer. At present, there are mainly two modes for building a network video monitoring system: 1. Use hardware encodin...
