Problems solved by technology
[0004] (1) The bandwidth and network conditions of each client are different, but there is only one high-definition video stream distributed, and its frame rate and bit rate are fixed, resulting in better video effects for clients with good networks. Clients with poor network experience video delays, freezes, etc.
[0005] (2) Due to the high bit rate of high-definition video, when the network between the monitoring equipment and the monitoring platform is poor, or intermittent jitter occurs, the video received by the monitoring platform will suffer from frame loss and delay. The network between the client and the monitoring platform is very good, and the video previewed by the client will also experience frame loss and delay.

Embodiment Construction
[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0035] see figure 1 As shown, the present invention is a real-time high-definition video stream distribution method of an adaptive network, comprising the following steps:
[0036] Step S1: When the client needs to preview the high-definition video of the monitoring device, the system first sends a command to the load balancing service;
[0037] Step S2: The load balancing service determines whether the secondary video stream of the monitoring device is already be...

The invention discloses a real-time high-definition video stream distribution method and system of a self-adaptive network, and relates to the field of security and protection monitoring. The system comprises a monitoring device used for collecting video data. the primary dispatcher is used for calculating an initial network bandwidth value of the transmission channel and obtaining a monitoring video; the second-level dispatcher is used for calculating an initial network bandwidth value of the transmission channel and sending processed video data to the client; the client is used for applyingfor real-time high-definition video preview; and the load balancing service is used for receiving commands issued by the client and the second-level dispatcher and carrying out judgment. According tothe invention, the network channel between the monitoring equipment and the first-level dispatcher is adaptively monitored at the monitoring equipment end; The network channel between the secondary dispatcher and the client is self-adaptive at the secondary dispatcher end, and the transmission code rate most suitable for the network channel is selected, so that the probability of the phenomena oflagging, delay, frame loss and the like of the video of the client is reduced, and the quality of the preview high-definition video image is improved.
Description
technical field [0001] The invention belongs to the field of security monitoring, and in particular relates to a network-adaptive real-time high-definition video stream distribution method and a network-adaptive real-time high-definition video stream distribution system. Background technique [0002] In the video monitoring platform, when the client needs to preview the high-definition video of the monitoring device in real time, it will first issue a video preview command to the monitoring platform, and then the monitoring platform will issue a preview video command to the monitoring device, and then the monitoring device will send the high-definition video stream to To the monitoring platform, the monitoring platform then sends the high-definition video stream to the client. When another client needs to preview the high-definition video of the same monitoring device in real time, it will first initiate a video preview command to the monitoring platform, and the monitoring ...
