Streaming media refers to media formats such as audio, video, or multimedia files that are continuously played on the network in real time using streaming technology. Streaming technology is also called

The traditional download method has a large delay, because audio and video files are generally large, and the storage capacity is also large. At the same time, due to the limitation of network bandwidth, downloading a file is time-consuming. Depending on the file size, it may take several minutes Even hours. This method not only wastes download time and hard disk space, it is important that it is very inconvenient to use. After the emergence of streaming media technology, people can "click and see". Multimedia files are downloaded and played at the same time, which not only greatly reduces the startup delay, but also does not require too much cache capacity, which greatly reduces the number of users waiting online. Time, but also increased interactivity.

With the popularity of the Internet, use

Streaming media technology plays an important role in Internet media communication. It facilitates people's global information and emotional communication. Among them, video on demand, distance education, video conferencing, Internet live broadcast, online news release, online advertising, etc. Applications are more widespread than ever.

Introduction to Streaming Technology

Nagar P2P direct-on-demand system provides video and audio stream distribution services installed on the server side. The system receives video and audio streams from the collection end, and forwards them through the P2P protocol and CDN network. It is transmitted to the client (mobile phone, tablet, computer, set-top box) through the media asset management system, content management system and website, and quickly establishes a set for customers Network video and audio direct-on-demand service.

Streaming technology features

Three-screen playback

Support common browsers on the market, including IE, Firefox, Mobile, Google and other browsers.

Support smart terminal viewing. VJLive supports HLS protocol, and uses HTML5 language to realize online live streaming of IOS system and Android system mobile phone and set-top box platform.

Live shift

Naga Live provides time-shift function, supports real-time playback in pure flash mode, automatically generates a program list, can watch any program at any time, breaks the traditional live broadcast viewing mode, and viewers no longer miss live programs because they cannot play back.

High fluency

Integrates HTTP, TCP, UDP (SUDP, RUDP) and gateway penetration module (UDP penetration and RPNP penetration) and global IP table, with extremely high data transmission and reception speed and single machine connection, which greatly guarantees a variety of clarity Video playback quality in degrees.

Broadcast HD

Supports multiple streaming protocols and encodings during live broadcasts. HD and SD streams can be used to achieve broadcast-quality effects. HD video formats include wmv / asf / wma / mp3 / rm / rmvb / flv.

Self-adaptive complex network environment

It adopts dynamic node adjustment strategies covering global IP table, operator's regional IP segment table, and supports gateway penetration at all levels and internal and external network gateway mapping. At the same time, UDP and TCP transmission adaptive mechanisms are adopted. When UDP transmission is not available, it automatically switches to TCP transmission to ensure connectivity.

Client and CDN automated storage

Viewers: The cache setting will automatically store the viewed video and audio clips for P2P sharing to reduce the bandwidth pressure of the operator.

Operators: Through the central video resource library, according to the click-through rate of on-demand server viewers, it automatically downloads popular video files for P2P distribution.

High-speed drag

Using the original frame-level pre-cache reading technology, the viewer can seamlessly jump to the dragging place while dragging the video progress and immediately enjoy the cross-segment video.

Frame-level jump positioning

Naga adopts the original VJVOD optimized encoding protocol, which can accurately jump to the time point in units of frames, and highly position to a picture that is more accurate than a second.

Rich resource distribution

Use on-demand media with full video, video cache clips or encrypted content in private or third-party formats. You can also publish non-media files in any format and use them as a P2P file publishing system, such as SWF games.

View progress memory

A breakpoint memory function that can be set and re-developed will be provided so that customers can continue to watch the program.

High-speed startup

Through the HTTP protocol, optimized encoding module, and cluster link strategy, video on-demand speed can be achieved without requiring viewers to wait for a long time to start watching videos.
