Application Layer Development and Design of HD Digital TV

摘要

With the rapid development of modern digital broadcasting, television watches are not only more and more critical about the quality of the pictures users see on the television monitor, but they are also more and more diverse about their demand on the OSD (On Screen Display) operation interface of the digital television. Users not only ask for high precision of the sensor reception of signal from the remote control, but users have more and more demand enticing qualities of menus displayed on the television screen. This thesis will first introduce IR's different encoding and decoding methods, give a brief introduction of the circuit for receiving IR signals, and then display the wave patterns used by the remote control designed, as well giving an analyses and appraisal of these wave patterns, make preparation for appraisal of the coding source of the OSD operating interface. And then the thesis introduces the functions of different path ways that can be supported by the integrated circuits of the NOVETIC series used in the present design, and briefly introduces the software platform used by this integrated circuit and its relevant accessory tools. Finally, based on the pre-existing hardware platform, I have designed a comprehensive OSD system with a unique style, as well as a remote control operation system that befits the modern day high definition digital television.
