Design And Implementation Of Digital Television Interactive System

In recent years,smart digital TV has been rapidly popularized in the vast number of households,becoming an indispensable household appliance for family leisure and entertainment.However,the electronic program guides used for digital TV program navigation are usually very complicated in structure and hierarchy,and it is difficult for users to find the content they want to watch through the traditional remote control.Therefore,it is of great significance and value for digital TV operators to improve user satisfaction and increase user stickiness by constructing a system that allows users to switch TV programs conveniently,intuitively and simply.Based on the national,industrial standards and technical specifications,combined with the actual needs of Sichuan Mobile for digital TV services,this thesis designs and implements an interactive system for controlling digital TV equipment using optical identification technology.The research work of this thesis mainly includes: understanding the specific situation of digital TV service,investigating the actual demand of Sichuan Mobile for digital TV program business,and proposing the research problems and solutions of digital TV interactive system;analyzing the non-dimensional of digital TV interactive system in detail functional requirements and determining the main functions of system research,including manipulating by point pen,media resource management,OID code management,statistical analysis management and system management;based on UML technology,constructing the use case model of corresponding functions and analyzing the use case specification of use case model;completed the overall design of the system,design of point pen and TV magazine,detailed design of main functions and database design;completed the implementation of digital TV interactive system with optical identification technology,OOP technology,database technology,Node.js technology,RESTful API technology,JSP technology,Android application development technology and Nginx technology;finally,test and analysis of the implementation effect of digital TV interactive system through test cases.This digital TV interactive system has been put into use at present.Its implementation has effectively reduced the complexity of using digital TV to watch programs and greatly improved the user's experience.At the same time,the system focuses on large TV screens and launches innovative home digital products,promoting the expansion of information consumption such as digital home and online education.It has a positive effect on building a smart family ecology,improving the satisfaction of family users,promoting the development of information technology,improving the level of digital services and promoting the prosperity of network economy.
