Application Domain: (Video Cloud)

Description

Some enterprises (e.g. start-ups) want to deploy video business with low cost and high efficiency, such as live video broadcasting. But two problems in the self-built video system:

  1. Expensive infrastructure resources: data center, CDN, server, bandwidth, etc.
  2. Complex audio and video technology: codec, transcoding, transmission, processing, multi terminal adaptation.

Some enterprises (e.g. top cloud service providers) have infrastructure, but no full load in practical, server resources are idle.

Video Cloud Service is a video streaming service based on cloud computing technology and provides the API and SDK for developers. It include capture, codec, storage, manage, transcoding, delivery, playback etc. Its goal is let users build professional video system in a low-cost and efficient way, and easily carry out video business. Video cloud uses P2P CDN technology to accelerate.
