Embodiment Construction

[0042] In order to make the embodiments, technical solutions and advantages of the present invention more obvious, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Example. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention.

[0043] The first aspect of the present invention provides a hybrid networking system of distributed nodes with multi-rate network ports. The system includes a management server, a receiving node, a sending node, a display device, and a video source. The video source and the video interface of the sending node pass through Video cable connection, the video interface of the display device and t...

Abstract

The invention belongs to the technical field of professional audios and videos, particularly relates to a hybrid networking system and method for multi-rate network port distributed nodes, and aims to solve the problem of how to send and receive video streams in a system in which the multi-rate network port distributed nodes coexist. The system comprises a management server, a receiving node, a sending node, a display device and a video source, wherein the management server manages the sending node to open / close multicast sending, configures a multicast address, sets bandwidth occupied by a video stream and configures the receiving node forming the same large screen; the sending node configures a preset bandwidth reached by the compressed video data, pre-compresses the video data according to the preset bandwidth through a compression algorithm, evaluates the compressed data volume, and selects a corresponding compression parameter to compress the video data to obtain the compressed data volume; according to the invention, a plurality of receiving nodes and sending nodes with different network port types can normally send and receive the video streams in a distributed splicing system, packet loss caused by the fact that the video streams exceed the network port capability of the nodes is prevented, and the quality of the video streams received by the receiving nodes is ensured to be the best as much as possible.

Description

technical field [0001] The invention belongs to the technical field of professional audio and video, and in particular relates to a hybrid networking system and method for multi-rate network port distributed nodes. Background technique [0002] With the development of network technology, more and more network-based distributed transmission solutions are used in the professional audio-visual field. All devices are connected to switches through network cables. The advantage is that the devices are relatively scattered and require less space. For places that have already been built, the network cables that have already been laid can be used. However, after adopting the fully networked design, it also faces common problems in networking of network equipment. [0003] One of the problems is that multiple network devices have different access bandwidths to the network, and they may have their own requirements for the quality of transmitted video. Then corresponding to the distri...
