Network integration of video surveillance services based on Ngn/ims (SIP Protocol) communication Platform

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 surveillance, remote access, centralized management needs. The industry has explored two ways to s

The RTP protocol details the standard packet format for transmitting audio and video over the Internet. RTP protocols are commonly used in streaming media systems (with the RTCP protocol), video conferencing and a Push-to-talk system (with either a/p or SIP), making it t

SIP's most popular communication protocols are mature

Introduction Communication providers and their partners and users are increasingly eager for a new generation of IP-based services. Now we have the SIP Session Initiation Protocol. SIP was born less than a decade ago in the computer science laboratory. It is the first protocol suitable for multi-user sessions in various media content. Now it has become the specification of the Internet Engineering Task Gro

SIP protocol (Chinese)-1

1. Introduction to the SIP protocol Many applications on the internet need to establish and manage a session. The session here refers to the exchange of data between participants. Considering the actual situation of participants, the implementation of these applications is often very complicated: Participants may move between agents, they may have multiple names, the communication between them may be based on different media (such as text, multimedia,

1 , what is SIPSIP (Session Initiation Protocol) belongs to the IP Application layer protocol, which is used to provide the user with session application on the IP network. A session refers to the communication of voice, video, and other media forms between two or more users, possibly IP telephony, conferencing, instant messaging, and so on.SIP is a signaling protocol that corresponds to a call signaling protocol (such as SS7 ISUP) in a traditional te

Basic SIP application solution

Basic SIP Application As one of the main VOIP communication protocols, the SIP protocol is simple, flexible, and open, and is gradually dominant in the VOIP communication field. The main methods used for SIP Communication include SIP terminals, proxy/targeted servers, location servers, and PSTN gateways. Currently, th

In addition, SIP uses the RTP/RTCP protocol (Real Time Transport Protocol/real time control protocol) defined in RFC 3550. It defines the multimedia package format on the IP network, also, the Session Description Protocol defined in RFC 2327 is used to define the parameters and features of a multimedia

new devices will be released for technological innovation to provide new methods and addresses for people's connections. In many cases, it is discovered that the convenience of these new devices is greatly reduced by the complexity of managing various addresses, messages and tools with different features, or even overlapping tools. The use of new devices also raises the question of how to contact others in the best way: "should I send an email or send a voice message? Which number should I use

SIP (Session Initiation Protocol) Conversation Initiation Protocol is an application layer control (signaling) protocol for network telephony and conferencing. It is mainly a multimedia communication protocol based on IP network. It can realize the signaling functions are also using RTP as a media transmission protocol.
