Applications Unified Access System Based On Video Cloud Computing

This paper describes the implementation of the application unified access system based on video cloud computing.The application only needs to follow the development of HTML5 standard,which is presented on the set-top box to achieve the purpose of rapid iteration of the application,so as to cope with the radio and television operators' obstruction,get rid of the difficulties and compete with them.The main work and achievements of the paper are as follows:1)the general plan of applying unified access system is designed.Considering the actual situation of radio and television,the overall implementation scheme of the unified access system is designed to realize the seamless access of the existing and mainstream peripheral hardware peripherals,and the extension requirement of the system for 5-10 years is considered,and the life cycle of the whole system software is extended.2)design the software scheme of the video cloud service platform and determine the hardware selection plan.The core design idea of this system is the ability of the physical set-top box.Through the application of the cloud computing in the video industry,the system is virtualized to the cloud,and the video is used as the server to present the business processing data to the client.The hardware selection of the real-time video coding is involved,and the advantages and disadvantages of various implementations are compared.After considering the situation,the hardware scheme of virtual set-top box and video coding is finally determined.3)optimize the implementation of key applications,thereby improving the efficiency of video coding and reducing the cost.Through the selection of several key application scenarios,the portal front page(Graphic + embedded small video),government application(pure Flash),film channel page(graphic text)as the optimization goal,combined with the theory analysis of the theory of video coding,to determine the optimization direction,based on the measured data,gives the application development specification,making the same The bandwidth and hardware capability can output more code streams,thus reducing the cost of single channel.This paper realizes and constructs a unified access system based on video cloud computing.Through a series of functions and performance testing and optimization,it basically achieves the expected design goal,and finally put into two cities to carry out pilot operation,and has achieved good reputation and social benefits.
