Abstract

The invention relates to a DVFS-based network video on demand server and application thereof. The network video on demand server comprises a processor, a storage hard disk, an index monitoring module and a random access memory, wherein the processor is used for processing an on-demand request of a user and transmitting a video on demand; the storage hard disk is used for storing a video source on demand of the user; the index monitoring module is used for monitoring operating state indexes of the server; the random access memory is used for performing DVFS adjustment on the processor according to monitored data of the index monitoring module; the processor is a multi-core processor based on DVFS, and is connected to the Internet network by means of an Ethernet interface; the Internet network is connected with a user terminal used for video on demand by the user; the random access memory is connected with the index monitoring module; and the processor is connected with the storage hard disk and the random access memory separately. Compared with the prior art, the DVFS-based network video on demand server and the application thereof can effectively reduce the overall energy consumption of the network video on demand server while satisfying video on demand.

Description

technical field [0001] The invention relates to a network video-on-demand server and its application, in particular to a DVFS-based network video-on-demand server and its application. Background technique [0002] Video On Demand (VOD, Video On Demand), combining video technology, network technology and computer technology, enables users to play videos according to their personal preferences, and provides users with real-time, convenient and interactive on-demand video services, which are widely used It is used in various fields such as learning and education, life and entertainment, business finance, smart home, security monitoring and so on. [0003] The network video-on-demand server, as the storage center and processing center of the video-on-demand system, is responsible for storing video sources, responding to requests from network users, and transmitting on-demand videos. With the continuous improvement of video quality and the rapid development of Internet technolog...
