VIEWGOOD Streaming Media Service Platform—Video On Demand Function Module (WebVOD)
The video on demand module is one of the important modules in the VIEWGOOD streaming media service platform solution. Can operate independently. The whole module is based on the B/S architecture, and adopts the VConnect service core with independent intellectual property rights of VIEWGOOD, in addition to supporting MPEG-1 (mpg, dat, mp3), MPEG-4 (avi, asf, wmv), REAL (rm, rmvb), REAL10 In addition to many mainstream streaming media formats, it also supports all non-streaming media formats. At the same time, it adopts NoDelay's original technology to support arbitrary drag and drop over the wide area network, and the response time is extremely short. Using the standard HTTP protocol, fully realize the support for multiple network cards, cross-network segments, cross-routes, and cross-firewalls. A single server supports 1000 concurrent streams (without buffering).
VIEWGOOD streaming media service platform - live video module (WebLIVE)
The live video module is one of the important modules in the VIEWGOOD streaming media service platform solution and can be operated independently. The whole module is based on B/S architecture, which combines the advantages of computer network technology and video technology, adopts VConnect service core with independent intellectual property rights of VIEWGOOD, and supports the most advanced MPEG-4, H.264 codec technology. Using the original KeyBuffer technology, the audio and video are fully synchronized, and the system delay is extremely short (within 1 second, the lowest can be as low as 0.1 second).
VIEWGOOD Streaming Media Service Platform——Ad Insertion Module (ADManageSystem)
The advertising insertion module is one of the important modules in the VIEWGOOD streaming media service platform solution.
How to implement the advertisement insertion function has always been a major problem in the streaming media business. The playback time of each streaming media program stream is different. If you want to insert an advertisement of any length at any point in time during the playback process, A rather difficult task for a video server. VIEWGOOD uses the original NoGap technology to realize the seamless connection between advertisements and streaming media, and provides a variety of advertisement insertion functions, including timing or manual insertion of video advertisements, text advertisements, animated advertisements, and combined advertisements.
VIEWGOOD Streaming Media Service Platform - Content Distribution Module (WCDN)
The content distribution module (WCDN) distributes streaming media content to the "edge" of the network closest to the user by adding a new layer of network architecture to the existing Internet, so that users can obtain the content they need nearby and improve user access The responsiveness of the content. VIEWGOOD technically solves the problems of backbone network congestion due to large user visits and uneven network distribution, and improves the scope and response speed of users' access to streaming media content. Relying on the most advanced content mixing optimization technology in the world, and supporting the distribution of multiple media format files with different code streams on the same edge server device for mixed deployment, it greatly saves the operator's server resources.
VIEWGOOD Streaming Media Service Platform——HP2P Technology
High-performance P2P technology with independent intellectual property rights, combined with P2P technology and HTTP technology, non-real-time data is transmitted by P2P, real-time data is transmitted by HTTP, which not only inherits the advantages of P2P technology (saving server resources, supporting large concurrency) etc.) and has the characteristics of fast response and good penetration of HTTP. It not only makes full use of the user's idle uplink bandwidth, improves the efficiency of streaming media transmission, but also ensures the user's playback quality.
1. Self-developed kernel
Use the underlying calls provided by Microsoft® to realize seamless connection with IIS.
The high-efficiency service kernel VConnect is used to fully ensure that the system has strong concurrent performance. Using advanced technologies such as multi-level thread pool, dynamic IP binding, and synchronous listening, fully realize the support for multiple network cards, cross-network segments and routers of the server.
Using efficient MPEG-4 codec technology and KeyBuffer buffer identification technology, the network transmission delay is extremely short, and the delay from collection, live broadcast to wide area network reception is as short as 0.1S.
Adopt NoDelay technology to make the drag and drop response time of on-demand programs extremely short, and the drag and drop response time of all streaming media formats is 0.1s to 0.5s.
2. Powerful system functions
(1) Introduce a distributed management solution, support server clusters, manage program resource indexes and user data in a unified manner through the data center, and realize the sharing of program resource servers and unified management of user information.
(2) The powerful program management mechanism establishes the strictest security guarantee by formulating different access rights for program resources. It also supports operations such as drag-and-drop movement and copying of multiple program types.
(3) Support remote management of program resources, user information, news announcements, etc.
(4) An efficient search engine coupled with powerful data management supports multiple search methods such as program classification and program query, and easily realizes users' fuzzy queries.
(5) Powerful user management mechanism, different users (groups) have different levels and permissions, and log in through their own user names and passwords.
3. Open architecture
(1) Rich media format support, and has the ability to expand, currently supports MPEG-1 (mpg, dat, mp3), MPEG-4 (avi, asf, wmv), REAL (rm, rmvb), REAL10 and many other mainstream streams media format.
(2) Open business expansion interface: the system has multi-level SDKs, such as EPG SDK, CMS SDK, and OSS interface SDK.
(3) Support interconnection with the operator's OSS (the operator's OSS is mainly composed of billing, business, accounting and customer service, etc.).
(4) Possess the ability to quickly integrate with third-party CMS.
(5) The interface is organically separated from the system, and the customization of the third-party interface is supported.
4. Carrier-level reliability and service provision capabilities
(1) Efficient content distribution technology (VConnect, KeyBuffer) suitable for live broadcast, Internet TV and VOD.
(2) Multi-directional system redundancy design and module hot-swappable support.
(3) Support high-quality video services, typically including:
MPEG4@2Mbps/1.2Mbps; WMV9@1.5Mbps/768kbps; RMVB@1.5Mbps/500kbps;
Real10@1.5Mbps/400kbps;
(4) Based on disk array technology, storage and data backup that can meet the characteristics of streaming media business.
(5) Strong concurrent performance and a stable system can help operators reduce system operation and maintenance costs and improve system service capabilities.
5. Excellent service ability and expansion ability
(1) High-density service capability, each standard server supports 1,000 concurrency, and can be linearly expanded.
(2) Supporting multi-level network deployment, the system can be easily expanded to millions of concurrent users.
