Digital Television Test Pattern Generation System Based On DSP

Digital TV is one television system in which all programme editing, sending, transmitting, and signal receiving, processing, displaying are conducted in the form of digital data. With the rapid development of computer technology, digital processing technology and image compress technology, broadcasting television has making great strides towards new era of digital television. The research on digital television is becoming one of the most important ones in the international high technology research fields because of its huge potential market and economic profit. As a necessary debug tool in the development and application of digital television, DTV test pattern generation device will be broadly applied to device manufacture, network installation, monitor of service running status and so on. So it is necessary to research and develop DTV test pattern gererator.This paper mainly introduces the theory and implementation methods of a digital test pattern generation system based on DSP, and describes the process of implementation for software and hardware in details. Firstly, there is a wide brief that general situation of DTV all over the world, the huge potential market of electronic measurement device, as well as the feasibility of DSP mode combined with simulation on PC. On the condition, advances a set of whole solution for system, which includes...
