Detailed data collection of streaming media technology

With the development of modern science and technology, the Internet has brought people various forms of information. From the first picture on the Internet to various forms of online video and 3D animation, the Internet has greatly satisfied people's audio and video. However, before the advent of streaming media technology, people had to download these multimedia contents to local computers, and after a long wait (due to limited bandwidth, downloading usually takes a long time), they could see or hear the information conveyed by the media. Fortunately, after the emergence of streaming media technology, people no longer need to wait for the media to be completely downloaded.

Streaming media refers to a media format, such as audio, video or multimedia files, which is played continuously in real time on the network by using streaming media technology. Streaming media technology is also called streaming media technology. The so-called streaming media technology is to compress the continuous image and sound information and put it on the website server. The video server transmits each compressed file to the user's computer in sequence or in real time, 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. This technology first creates a buffer on the user's computer, downloads a piece of data as a buffer and then plays it. When the actual connection speed of the network is less than the speed consumed by playing, the player will access a small piece of data in the buffer, which can avoid the interruption of playing and ensure the quality of playing.

Bandwidth pressure. Operator: According to the click rate of viewers on the VOD server, the popular video files are automatically downloaded through the central video resource library for P2P distribution. High-speed dragging adopts the original frame-level pre-cache reading technology, which allows viewers to seamlessly jump to the dragged place and enjoy the cross-sectional image immediately when dragging the video progress. Frame-level jump positioning Naga adopts the original coding protocol optimized by VJVOD, which can accurately jump to the time point by frame, and the positioning picture is more accurate than the second level. Rich resource distribution uses complete video, video cache fragments in private or third-party formats or encrypted content as on-demand media. You can also publish non-media files in any format as a P2P file publishing system, such as SWF games and so on. The memory of viewing progress will provide a breakpoint memory function that can be reset and developed to facilitate customers to continue watching programs. High-speed startup realizes the point-and-play video startup speed through HTTP protocol, optimized coding module and cluster connection strategy, and the audience can start watching the video without waiting for a long time.
