Distributed code conversion task scheduling system and method based on video image group segmentation

Abstract

The invention discloses a distributed code conversion task scheduling system based on video image group segmentation. The distributed code conversion task scheduling system is connected to the broadcast television network, the telecommunication network and the Internet and receives content data provided by a content provider. The distributed code conversion task scheduling system comprises a content receiving interface, a storage system, a code stream pre-processing module, a code stream segmentation module, a plurality of code conversion nodes, a code stream combining module, a code stream post-processing module, a content sending interface and a task scheduling module. The task scheduling module is connected to the various components. After receiving the content data, the task scheduling module enables the content data to be set as tasks, sends control commands to the various components and indicates working of the components. Further disclosed is a distributed code conversion task scheduling method. The distributed code conversion task scheduling method is based on video image group segmentation.

Description

technical field [0001] The invention relates to video code stream transcoding technology, in particular to a distributed transcoding task scheduling system and method based on video image group segmentation. Background technique [0002] At present, my country has 500 million mobile phones, 350 million household TV sets and 122 million personal computers connected to the Internet. These electronic devices constitute a huge terminal group and a huge market covering a variety of consumer groups. Facing this market, the business integration of radio and television networks, telecommunication networks and the Internet will not only drive investment and consumption of 600 to 700 billion yuan, but also create about 200,000 jobs. From the point of view of expanding domestic demand and responding to the global financial crisis, the "triple play" is of great significance. [0003] In the field of video services, the integration of the three networks will lead to a series of changes ...
