Digital IP network broadcasting system in a broad sense
The so-called streaming media belongs to the category of media format, its carrier is internet, and its transmission existence mode is streaming. Such as: audio, video, multimedia files and so on. Streaming media has its own unique form of playing, that is, it does not need to download the whole file before playing, but only stores the content of the beginning part, and then buffers the media data when the network buffers the playing data. Will output. It can be said that the characteristics of streaming media data are as follows: Only in some cases, it will start slowly. In addition, another significant difference between streaming media and print media is that streaming media can be downloaded while playing. Taken together, the most salient features of streaming media can be classified as "interactive" and "interaction" is also the reason why the Internet is really popular.

Digital IP Network Broadcast System Development Process
2.1RTSP - Real-time streaming protocol Real-time streaming protocol is one of the streaming media protocols. It is jointly developed by Real Networks, Columbia University, and Netscape Communication and has now become the IETF standard. The characteristic of this protocol is that it is a control protocol for transmitting information through real-time data. Its definition is derived from the fact that his own application adopts a one-to-one or one-to-many way to transmit using network IP. Multimedia data to complete. RTSP as a protocol itself needs to rely on RTP or TCP for effective data transmission, and it alone can control the knowledge of its own data transmission. In this way, it will have a clear difference compared with HTTP, as follows:
RTSP is to rely on RTP to complete the streaming media data transmission, which is characterized by two-way interaction; and HTTP is to rely on HTML to complete streaming media data transmission, which is characterized by a one-way protocol. Through this comparison, we can clearly see the advantages of RTSP, in addition, he also extended its function, namely: It can complete the transmission of audio or video data. It can be said that this agreement has broadened the path of transmission channels of network broadcasting, giving them the opportunity to choose, so that they can choose according to their actual needs whether the next link method is TCP or UDP. Here, in order to ensure the reliability of control commands, most people choose TCP links.
Digital IP Network Broadcast Intercom System Session Protocol
The abbreviation of the session description protocol is SDP. It is published by IETE on the way of RFC2327. The significant function of the SDP session-familiar protocol lies in the description of the multimedia session, that is, he can go to the announcement and invitation of the implementation session of Ang-weifang. Wait. It can be said that the emergence of the SDP protocol can effectively activate the multimedia conference, that is, to facilitate the effective communication of the streaming media information, so that the recipient of a specific session description participates in the conversation. However, it should be noted that this protocol cannot be used to negotiate media coding methods. At present, this protocol is used more frequently on the Internet. The reason is that in the context of this network environment, a typical multimedia session presents a group of streaming media in a specific period of time. Its characteristics are many-to-many, that is, he The description of the object is mainly the language of the media film and control commands, and the value of the SDP description language in the streaming media playback process lies in that it communicates through the language.
IP Network Broadcast System Protocol - Real-Time Streaming/Control Protocol
As a kind of protocol, real-time transport protocol is mainly a protocol for transmitting multimedia data on the network. His scope is narrow, and its release form is also limited. There are only two types: RFC1889 and RFC3550. This has made his characteristics determine that he is the application layer transmission protocol. The lower layer linking it is implemented through UDP, and other connection methods can also be selected, such as: TCP, ATM and so on. In general, RTP itself can only control the real-time data in real-time and cannot control the sequential streaming media packets in real time, and it cannot control traffic or congestion to provide information, that is, everything. The streaming media transmission work must be systematically implemented by the associated protocol of this protocol.
RTCP Chinese means a real-time transmission control protocol. His core value lies in the conscious control of streaming media data applied to the network in two forms: media server and player. That is to say, during the implementation of the protocol session, the data information or data packets that are present are all periodically transmitted by the server or the broadcast period, and mainly include: the transmitted media data and the lost data, etc. Forms to show, statistically strong. Such characteristics make the information fed back by the client cause the server's own transmission speed to change accordingly, so as to better match the network conditions. Practice has proved that the use of both RTP and RTCP can promote the transmission rate to reach the state, and then effectively implement streaming media data transmission over the network.
Analysis of Streaming Media Server Broadcasting over IP Network
Currently Helix Server, Darwin Streaming Sever, and Windows Media Service are some of the mainstream streaming media service platforms. Helix Server and Windows Media Service are the most widely used applications for Webcasting. Among them, the earliest used streaming media system is a series of products of Real Networks, and he is also the provider of more online streaming media solutions in the world, that is, providing a series of products related to the server to the client. Microsoft's latest streaming media solution, Windows Media Service9, is characterized by its convenience, innovation, integration, and low cost. It has become a mainstream product in the streaming media market. In particular, its integration with the operating system makes people You do not need to purchase it separately when you purchase. In this regard, the author believes that in the selection of streaming media streaming media server can be based on the trend of development needs and the comprehensive characteristics of the product to consider, you can choose Windows Media Service 9, easy to use, low cost, strong performance, etc., in one fell swoop.
The emergence of streaming media technology in online broadcasting is a trend of the times, not only broadening the scope of traditional broadcasting, but also highlighting the impact of broadcasting. It can be said that streaming media technology has injected new vitality into broadcasting and promoted the effective and continuous development of broadcasting.

IP network broadcast systems and traditional broadcast distinction <br> <br> traditional broadcasting communication technologies have certain predetermined frequency and transmit power, which broadcast coverage have certain constraints, but are also the audience received the order , Shorter time, making the audience receive a strong passivity. Internet radio not only has the flexibility and vividness of traditional forms of broadcast and television, but also can interact with the Internet to broaden its scope. Here, I roughly explore the streaming media technology in webcasting.
