This article will explain in detail what streaming media technology means in the Internet. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

With the development of modern technology, the network brings people a variety of information, from the first picture appeared on the network to now various forms of network video and three-dimensional animation, the network makes people feel very satisfied. However, before the advent of streaming media technology, people had to download the multimedia content to the local computer after a long wait (it usually takes a long time to download because of the limited bandwidth). Before you can see or hear the message from the media. Thankfully, with the advent of streaming technology, people no longer have to wait for the media to be fully downloaded.

Basic introduction of streaming Media Technology

The time delay of the traditional download method is very large, because audio and video files are generally large, and the storage capacity required is also large. At the same time, due to the limitation of network bandwidth, it is very time-consuming to download a file, depending on the size of the file. It may take minutes or even hours. This method is not only a waste of download time and hard disk space, but also very inconvenient to use. After the emergence of streaming media technology, people can "click and watch", and multimedia files are downloaded and played at the same time, which not only greatly shortens the startup delay, but also does not need too much cache capacity, and greatly reduces the time for users to wait online. And it also improves the interaction.

Streaming media technology is not a single technology, it is an organic combination of network technology and video / audio technology. To realize the streaming media technology on the network, we need to solve the problems of the production, release, transmission and playback of streaming media, and these problems need to be solved by using video and audio technology and network technology.

Transmission problems of streaming Media Technology

1. Problems solved in technical aspects

For streaming media transmission on the Internet, the transferred files must be made into streaming media format files suitable for streaming media transmission. The capacity of multimedia files stored in the usual format is very large, and it will take a long time to transfer on the existing narrowband network. If the network is busy, it will cause transmission interruption. In addition, the usual format of streaming media can not be transmitted according to the streaming media transmission protocol. Therefore, the files that need to be transmitted in streaming media format should be preprocessed and compressed to generate streaming media format files. Two points should be paid attention to here: one is to choose an appropriate compression algorithm for compression, so that the generated file capacity is small. Second, you need to add streaming information to the file.

2. Problems to be solved in transmission

The transmission of streaming media needs an appropriate transmission protocol. Most of the file transfer on internet is based on tcp protocol, and some of them are transferred in the way of ftp transmission protocol, but these transmission protocols can not achieve real-time transmission. With the in-depth study of streaming media technology, the more mature streaming media transmission generally adopts the rtp/rtsp real-time transmission protocol based on udp protocol.

Streaming media refers to the media format that uses streaming transmission technology to play continuously in real time on the network, such as audio, video or multimedia files. Streaming media technology is also called streaming media technology. The so-called streaming media technology means that the continuous video and sound information is compressed and put on the website server, and the video server transmits each compressed packet sequentially or in real time to the user's computer, so that the user can watch and listen while downloading, instead of waiting for the whole compressed file to be downloaded to his own computer. In this technology, a buffer is created on the computer at the user end, and the next piece of data is used as a buffer before playback. When the actual connection speed of the network is less than the speed consumed by playback, the playback program will access a small section of data in the buffer zone. This can avoid the interruption of playback and ensure the playback quality.
