AI Technical Summary

Benefits of technology

This technology helps maintain better image resolution by utilizing both udp (Ultra High Definition) videos with improved compression ratio or other techniques like H264/AVC (Advanced Vision Cable). Additionally, it allows users to customized how they watch images based upon their needs without any delays caused through delayed transmission from one server to another. Overall, this technology enhances overall performance while ensuring good picture quality at varying networks' circumstances.

Problems solved by technology

The technical problem addressed by this patented solution is how to maintain stable and efficient video streaming for both wired networks (WL) or wireless ones while also reducing any changes that may affect image quality caused due to factors like variations over time during data transfer between devices connected through different types of connections such as USB).

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] refer to Figure 1 ~ Figure 4 , a video surveillance client adapting to various network conditions. According to attached figure 1 Build a working environment, which consists of three parts: client, server, and device. The client communicates with the server over the wide area network, while the server communicates with the device over the local area network. Wide area network communication usually produces large packet loss, so packet loss needs to be dealt with, while LAN communication does not need to worry about this.

[0025] According to attached figure 2 Its basic signaling interaction uses the SIP+UDP protocol. The communication between the client and the server is WAN communication. Operations such as real-time video requests and video playback requests are completed by the SIP protocol, while video stream transmission and retransmission requests ...

Abstract

The invention discloses a video monitoring client suitable for various network conditions. The video monitoring client comprises an SIP communication module, a UDP communication module, a video data analysis module, a video data packet loss retransmission module, a video playing module and a video playback module. The SIP communication module is in data communication with a server by adopting an SIP + XML protocol; after receiving the video data packet, the UDP communication module transmits the video data packet to the video data analysis module for data analysis; a video data analysis moduleextracts H264 video data from the video stream data and analyzes the data; and the video playing module plays the H264 video data on an interface, the video data packet loss retransmission module completes retransmission and packet supplement of the video data when the video data packet is lost, and the video playback module requests historical video playback. According to the method and the system, the video monitoring client adopts UDP video packet loss retransmission and adjustment for behaviors of clients with different network conditions, so that the video quality of the video monitoringclient under different network conditions can be greatly improved.
