Desigh And Implementation Of Multimedia Broadcast Control System Based On Visual Component

The development and popularization of Internet technology has spawned the broadcast control system.As the alternative to traditional media services,the broadcast control system has the advantages of convenient operation,management,and so on.It can configure and schedule the terminal media services scattered around at the platform control side,without requiring manpower to configure and manage each terminal manually on the spot.However,the traditional broadcast control system pays more attention to the business scheduling of the terminal equipment,but ignores the efficiency of task configuration,management and user experience of the platform control side.The managers always need redundant operations of task configuration to configure the media business.And the broadcast effect will be checked only after the task has been sent to the terminal.Besides,the efficiency of multimedia services is very low.It is necessary to find a more efficient,faster,high service adaptability and strong visual effect mode for the business configuration of multimedia broadcast control system.This paper analyzes the requirement of the multimedia broadcast control system,discusses the deficiency of the traditional media broadcast control system in the business configuration and management,and proposes a multimedia broadcast control system based on visual components.By using visualization and component technology,the visual component library for multimedia services is built,and the broadcast task is modularized and segmented.Then the multimedia broadcast control platform is designed and implemented based on Web application.Through this mode,the adaptability of the broadcast control system to the multimedia services can be greatly improved,and the various media services will be more easily combined and tested.At the same time,the system has more expansibility and maintainability.It is only necessary to configure the visual component library in the development and configuration of new business.Firstly,the paper analyzes the present situation and the demand of the multimedia broadcast control system,then designs broadcast control system scheme based on the visual component library.The scheme includes system architecture,component library structure,business structure,business configuration process and business management mode,and makes a detailed description of each module of the system.Besides,this paper designs and optimizes the task scheduling scheme and algorithm based on component,and verifies it through function and performance test.Finally,the paper summarizes the work,and puts forward further goals and development direction.
