Research And Implementation Of Digital Video Broadcast On Expert Control

In software projects, there will be a variety of program control subsystems. The adoption of these control subsystems can enhance the control system of the software at the robustness, the flexibility, the reusability and the stability. Digital Video Broadcasting System is a great communication system. This system is divided into the physical collection, source coding, signal multiplexer, storage, and playback module parts. These parts require application of various algorithms or control methods to enhance the system’s features. This paper has token the Expert Control of Automation Control Field into Digital Video Broadcasting System. Using the method based on the application of Expert Control System, solved the problems in the embedded software development process.This paper’s beginning will make a comprehensive study based on DVB system. This study is mainly divided into three parts which are transmission of data stream, storage of data stream, processing of data stream. It will mainly study the important part of DVB satellite broadcasting system and MPEG-2standard, and will make series of analysis on the signal encoding and signal multiplexing. Before the research and implementation, I completed the development and signal environment.What’s the main narrative of the third chapter is how to establish a Regulation Control Module of a lightweight Expert Control System. Through this module we can accelerate the EPG display system.In the fourth chapter, mainly through the establishment of Expert Control System, we can achieve an intelligent Establishing system of stream channel at multi-model, multiple inputs and multiple outputs.What’s the main narrative of the fifth and sixth chapters is to establish two lightweight Expert Control Systems. Through this we can enhance the Playback system’s stability and comfort by using.Research and implementation of the above summarized some control methods which are commonly used in engineering practice. These methods are frequently used in a variety of software Expert Control systems, and they are very effective. Through this kind of research and implementation, we can improve analysis and implementation capabilities of the control system in the software project.
