One-chip TV

Abstract

One-chip TV is a system that can do all the signal processing between the tuner output and the inputs of the power amplifiers of the display and sound systems. It is a very application specific system on silicon, targeted at the standard definition TV receiver market (NTSC, PAL and SECAM). In the world of "Systems on Silicon" it is a rather unique system, since all signal processing is analog, while the control and adjustment signals are digital. As a product, it can be applied anywhere a standard TV receiving function is needed: TV sets, TV receiver plug-in cards for PCs, and so on. The current system is the result of a number of cooperating influences: market characteristics and set maker requirements, current TV standards, and capabilities of current silicon technology. In this paper these influences are explored and it is shown how they have shaped the present form of one-chip TV.
