Currently, video conferencing has been widely used, and our video conferencing system has been put into use. We have successfully held several major conferences, which play a very important role in daily office meetings. The following section briefly introduces the knowledge base of the

. H.323 ProtocolH.323 is the recommendation of the ITU-T 16th Working Group, which consists of a group of protocols, including the encoding, decoding, and packaging of audio and video signals, and the signaling for sending, receiving, and controlling call signaling, there are also Signaling Mechanisms Responsible for capability exchange. Version 4th of H.

Connection Control, routing, network resource management, billing, authentication, and other functions. The Softswitch device communicates with various media gateways, terminals, application servers, and other Softswitch devices using standard protocols. H.323 is the recommendation of the ITU-T 16th Working Group, which consists of a group of protocols, including the encoding, decoding, and packaging of audio and

control layer, provides various service Connection Control, routing, network resource management, billing, authentication, and other functions. Softswitch devices communicate with various media gateways, terminals, application servers, and other Softswitch devices using standard protocols. h.323 is the recommendation of the ITU-T 16th Working Group, it consists of a group of protocols, including encoding, decoding, and packaging of audio and

signaling channel, call signaling channel, and H.245 control channel. The coordination of the three channels enables H.323 calls.　　The following section describes the components and channels of H.323: 3.1 components.　　H.323 defines four main components to construct a network-based communication system: Terminal, Gateway, keeper, and MCU ).　　3.1.1 Terminal)　　An I

accepted by the H.323 gateway. The audio streams are converted into IP data packets and transmitted to the specified telephone terminal under the destination gateway through the IP network; at the same time, the call from the IP network (from the computer terminal or another PTT Network) can be transferred to the PSTN destination terminal. 4. Protocol features: Based on the concept of network guard, the

current telephone penetration rate is high, especially for mobile phones, which are now developing rapidly, that is to say we can participate in conference calls anytime, anywhere, through a variety of communication devices　　3. Emergency response When there is an emergency meeting, only the phone can guarantee the fastest speed to find the relevant personnel　　4. Good quality relative to the Internet voice communication, telephone call quality is much better, and more secure　　5. Low cost The con

This solution is based on P2P technology, with low server pressure and smoothness. Users can obtain data from each other to relieve the pressure o

According to the investigation and analysis results, the amount of visual information obtained by humans accounts for about 70% of the total amount of information, and the application scope of video technology is constantly expanding. For video conferencing systems that rely on network operations, the network environment plays a decisive role in meeting results.

development. The disadvantage is that the model is simple and the port without oicp supports large data volumes. 4.Use the ranknet library for development Raknet is also a C ++ network library based on UDP network transmission protocol. It uses database functions to implement efficient network transmission services. Its specific application in some game fields, radnet can be implemented in twoProgram25,000 pieces of information are transmitted eve

the transmission of the specific video data stream. The C in the RTCP protocol is the meaning of control, which is used for control over the video stream data, packet loss or bitrate.The protocol family RTSP is based on TCP, RTP, RTCP based on UDP. However, it is also possible to transfer RTP and RTSP together on the

I. Overview Review the video surveillance market, the monitoring platform system used by the signaling control protocol is not unified, resulting in the interconnection of the technical threshold. This is a bit similar to the 80 's China's switch market eight system of the situation. These reasons hinder the network era of large-scale carrier-level video surveill

two sub-protocols, RTP and RTCPData Transfer Protocol RTP, for real-time transmission. The protocol provides information such as timestamp (for synchronization), serial number (for packet loss and reorder detection), and payload format (the encoding format used to describe the data).Control Protocol RTCPfor QoS feedback and synchronous media streaming.
