Software Device Driver Development & Automation of Test Framework

Abstract

Digital TV is becoming an emerging consumer electronics appliance. Set-Top- Box (STB) is the migration from analog to digital broadcasting. Set top Box is an instrument which converts the transmitted digital video signals to the data or the signals which can be displayed on the standard LCD, LED, and analog TVs. In this report, basic overview and essential fundamentals of Set-Top-Box are discussed. For successful launch of any product and application, development and validation has to follow designing. Hence, validation approach is dealt in detail and it is following by testing of real time embedded systems like STB development board. This report includes the generalize development procedure of the frontend device drivers of STB like Tuner, Demodulator and Forward error correction (FEC),Device driver testing and debugging techniques have been explained, as a part of embedded software development. Finally Automation of test framework in Set-Top-Box integration has been included.
