The Research And Implementation Of Cable TV Program Editing System For Sichuan Radio And Television Company

Since John Logi Baird invented the world's first television in 1925,television has become an indispensable household appliances in people's lives.This thesis will implement a cable TV Editing System,which will make the production and management of television more convenient and efficient.This thesis will study and implement the cable TV program editing system based on the business publishing platform(BDP)of Sichuan radio and television network company.The system breaks the traditional unified television service mode,not only can achieve the user's personalized needs by region and so on,but also can serve some enterprises,such as hotels,resorts and other enterprises.The system is the standard B/S architecture.This thesis will design and implement the cable TV program editing system with the technologies of RESTful Web Service and mysql.This system includes two function modules which are template management and template instance management,and each function module includes the child module which provides the function of creating,deleting,updating,and finding for templates or template instances.It is vital that this system can meet the needs of personalized video services for users.This thesis will mainly study the following contents.Firstly,the system will be coded to implement all functions using the framework of Jersey,which is the standard implementation of the RESTful web service.And then the problem of cross domain will be solved well by using the way of CORS(Cross-Origin Resource Sharing)and JSONP.Based on the canvas API,the system can make users draw templates by dragging mouse,and the templates' data will be sent to the server by the Ajax of jquery.Secondly,this thesis will discuss three classic image zoom technologies,and analyze the advantages and disadvantages of each algorithm.Then the thesis will propose an improved algorithm which makes this system has no distortion and decrease the running time.Finally,the modules of this system will be tested in detail to ensure that the system meets the expected requirements.And the following work will be summrised.
