Driven by modern technology, the live broadcast platform has been developed and has become an important channel for people all over the world to share and disseminate content. The live broadcast platform is becoming more and more popular, and developers are urged to develop better live broadcast platforms. Most Everyone understands that in order to develop a better live broadcast platform, it is inseparable from various high-quality functional technologies. However, in the development process of the live broadcast platform, there is another key thing that requires developers to develop and utilize it carefully. This Stuff is the "protocol". The agreement developed by the live broadcast platform is related to the normal function and technology of the live broadcast platform to provide services. Starting today, I will analyze various protocols in the development of the live broadcast platform for you. Let’s first analyze the first protocol, which is called: Session Initiation Protocol SIP.
- The role played by the development of SIP on the live broadcast platform
- Real-time communication session: When users use the live broadcast platform, many users will see or use related functions such as microphone connection and calling in the live broadcast room. SIP is often used to establish these real-time communication session functions. First of all, users can establish call requests with SIP, establish communication connections with other users, and can interrupt requests; secondly, in the live broadcast room of the live broadcast platform, we can see multiple people talking on the same screen, and SIP supports multiple users on the same screen. Communicate during the call; finally, the SIP protocol can also maintain the status of the real-time communication session when the live broadcast platform users are in the real-time communication session, so that the system can identify and correctly handle the status change of the real-time communication session.
- Authentication and authorization of user communication: The security of the live broadcast platform is the top priority for developers to develop the live broadcast platform. The user's real-time communication session must also be secure. Many criminals will invade the live broadcast platform and use communication to threaten the security of legitimate users. It can verify whether the user is a legitimate user, so that illegal users cannot participate in real-time communication sessions, and the rights and interests of legitimate users are guaranteed.
- Multi-device communication: Each user uses different devices on the live broadcast platform. Smart devices such as mobile phones, computers, and tablets can all use the live broadcast platform, so many users worry about whether they can use the live broadcast platform on different devices. Communication, SIP can span different device networks and protocols, allowing users of different devices to communicate normally.
- Messaging: In addition to real-time calls, SIP can also be used to send short messages, status updates, etc., increasing communication channels between users.

import sipy
class VideoStream:
def __init__(self, url, sip_url):
self.url = url
self.sip_url = sip_url
def stream(self):
sip = sipy.SIPSession(self.sip_url)
sip.set_conference_id("直播平台")
sip.set_control_policy(sipy.CODELOG)
media_stream = sipy.MediaStream()
for line in self.url:
media_stream.append(sipy. media.Audio(line.decode("utf-8")))
sip.send_media_stream(media_stream)
url = "bogokj-bugukj"
sip_url = "bogokj-bugukj"
class VideoStream:
def __init__(self, url, sip_url):
self.url = url
self.sip_url = sip_url
def stream(self):
sip = sipy.SIPSession(self.sip_url)
sip.set_conference_id("直播平台")
sip.set_control_policy(sipy.CODELOG)- in conclusion
Today’s analysis of the SIP protocol developed by the live broadcast platform is here. It is not difficult to see that the SIP protocol is related to whether the real-time communication and multi-party interaction of the live broadcast platform can provide services normally, ensuring that users can communicate with audio and video with high quality and stability. This creates a richer live broadcast experience.
