GB28181 streaming transmission modes
UDP
The server monitors the UDP port and informs the device port through INVITE signaling, and the device actively initiates a request to the server. Streaming transmission
TCP passive
The server listens to the TCP port, informs the device port through INVITE signaling, and the device initiates streaming transmission to the server
TCP active
The device informs the server of the TCP port that the server is listening to, and the server actively pulls streams to the device. This scenario is rare, and the network where the device is located can be accessed by the network where the service is located (as follows) The upper-level device and the upper-level GB28181 service are in the same LAN, or they are both on the public network and can access each other).
Three mode switching to solve different network scenarios
The above three mode switching can solve the choice of streaming transmission mode switching in different network environments. The following is liveweb Screenshots from streaming platforms:
liveweb streaming media service software: Provides user management and Web visual page management; Provides device status management, which can check whether the device is offline in real time; Real-time streaming media processing, PS (TS) to ES; Equipment status monitoring, PTZ control, Video retrieval and playback; Provide multiple protocol stream outputs such as RTSP, RTMP, HTTP-FLV, HLS, etc.; Provide external HTTP API interfaces for server acquisition status, information, control, etc.
Supports local, intranet, and private cloud deployment; for enterprise video capacity building, it provides video on demand transcoding, mobile live streaming, cloud video storage plan, RTMP streaming service, RTSP streaming service, and equipment GB28181 interface Input, Onvif PTZ control and other capabilities, while providing powerful and stable RTMP/HLS/RTSP/HTTP-FLV distribution, supporting H5 page live broadcast without plug-ins, powerful background management, detailed secondary development interface documents, and simple service establishment One-click startup after decompression, supports deployment in Windows and Linux environments
