A digital TV content distribution system and method based on cloud platform

Abstract

The invention discloses a cloud-platform-based digital television content distribution system and method. The system comprises a central storage distribution system, a video flow push system and a cache system. The central storage distribution system is used for conducting injection and recording operations on medium resource files with metadata, storing the medium resource files, storing the metadata of the medium resource files and dispatching the medium resource files stored in a cloud storage server and a cache server. The cache system is used for storing the medium resource files, distributing the medium resource files operated by a data management system to the video flow push system. The video flow push system is used for pushing the video content to a video flow distribution network. The cloud-platform-based digital television content distribution system and method have the advantages that storage is based on a cloud platform, the memory space of the content distribution system is greatly increased, and massive dilatation is facilitated; the cloud platform is made to have high IO handling capacity through a cache mechanism; a great number of cheap cloud storage nodes are arranged, the defects that the performance is sufficient and storage is insufficient are overcome, and the system construction cost is greatly saved.

Description

Technical field [0001] The present invention relates to the field of digital television, in particular to a digital television content distribution system and method based on a cloud platform. Background technique [0002] In the wired interactive digital TV VOD (VOD, Video On Demand, short for video on demand technology, also known as interactive TV on demand system) system, a unified centralized content distribution system is a low-level capability component that provides content storage for various services At the same time, it also provides the client with the ability to obtain content, which involves the injection, management, storage, and video stream push of media resources, and is finally distributed to user terminals through IPQAM (Edge Modulator). The existing content distribution system is based on NGOD (Next Generation on Demand Video Architecture, the basic architecture of a new generation of video on demand service) specifications, and its storage is mainly composed...

Problems solved by technology

[0009] The technical problem to be solved by the present invention is that the storage server hardware resources in the above-mentioned prior art have single purpose, independent functions, low reuse rate, and a large number of storage nodes lead to huge pressure on the management server, which is not conducive to large-scale expansion, storage server architecture and Its software cost leads to high unit storage cost, which is not conducive to cost saving, and the central storage of the content distribution system has high requirements for storage capacity. The existing dedicated software and hardware architecture has more than enough performance but insufficient storage, which is not suitable for existing business needs. Provide a digital TV content distribution system and method based on cloud platform
