Program overview

Jiachuang has many years of experience in the construction of video platforms in the radio and television industry, from traditional DVB to all-IP, from data to transmission, from NGOD to OTT. In this process, it has accumulated relevant technical software and practical experience in independent research and development and integrated construction. Therefore, Jia Chuang has a complete OTT platform system architecture, a completely independent product support system and rich project construction experience.

The AVIT OTT platform includes two main services, business services and capability services, supporting peripheral systems such as offline/online transcoding systems, advertising systems, messaging systems, etc. It has a clear system hierarchy and rich peripheral system docking interfaces. Clarify the logical relationship and hierarchical structure between the systems.

Program features

At the same time, it supports the use of NGOD.C2 and HLS video streams for content input and caching. Regardless of which method is used to obtain content, it can support RTSP and HLS protocol output, compatible with the current parallel use scenarios of NGOD and OTT platforms in radio and television, and unified Platform, the user has no perception;

The content that supports multi-protocol output can only store one physical file, which greatly saves the utilization of storage space. At the same time, it also reduces the management difficulty of the media asset file by the business platform, and improves the management efficiency of the media asset content level;

Support integrated live broadcast technology, receive a piece of content, and support HTTP, HLS, RTSP live broadcast at the same time, saving live broadcast receiving server. Adopt live broadcast relay technology, a cache, accelerate multiple live broadcast services at the same time, accelerate multi-regional nodes, save backbone network bandwidth, and save cache servers;

Support IP multicast live broadcast technology, receive TS stream, mark RTP packet, generate FEC forward error correction code, and then send multicast stream to the configured multicast address;

Support multicast live FCC fast channel switching technology, the FCC server issues a unicast program stream starting from a key frame to increase the channel switching time, avoid waiting for the key frame time and IGMP interaction time, increase the key frame transmission time, thereby increasing the channel Switching speed

Meet the multi-level caching technologies such as multi-source site multi-service fusion caching, cache aggregation, slice memory caching, multi-level disk caching, etc.;

Design system security from content level, system level, and link level. Multi-level security assurance mechanism and redundancy mechanism make the overall platform reliability reach the broadcast level;

 

Solution architecture

The service layer of Jiachuang’s OTT platform is the MMSP product. It has all-media and full-service operation capabilities, can realize multimedia communications, can realize cross-platform, cross-network, and cross-system integrated services, and complete unified service access and unified service operation management Certification and authentication, unified product management, unified content management, unified capability management, unified session management, and unified resource management.

Jiachuang’s OTT platform capability service layer is the integrated CDN (Content Delivery Network) product, which provides a content distribution network platform for radio and television. Through the construction of the central OS system and the construction of the integrated Cache system, the content is distributed to the edge closest to the user. Users get the content they need nearby, reduce backbone network bandwidth, increase user access speed, and reduce bandwidth costs for operators.

The converged CDN system provides radio and television with a complete DVB+OTT service converged CDN solution, which can not only meet the needs of new radio and television IP-based services, but also benefit the existing DVB services. Adopt a flexible layered architecture to support CDN docking between national platforms and local platforms. The integrated CDN system realizes functions including central storage, cache acceleration, streaming media services, and intelligent scheduling.
