8、Software Platform Reference TV Application 8-1 Introduction This document describes Phobos’s reference TV application, supporting the basic control functionalities required to watch television. The reference application is designed to assist Phobos customers inimplementing a DTV system, using the Generation9-Elite IC and its APIs. This reference application is intended to support U.S.
8-2-3 Channel Change There are three ways to select a channel in the reference TV application: channel up/down, digital, and last buttons in remote controller. • Pressing the channel up or down key tunes to the next highest or lowest channel in the selected channel map; a channel in a different channel group (analog or digital) is tuned at the limits of the available scan. The channel map is established through the Auto Program menu, which automatically removes any no signal channels.

ATSC+NTSC TV RF signal are separated into 2 way output when enter into Tuner. One is NTSC (Analog signal) that output video signal by mixing, amplifying, demodulating. Video signal are separated into Y/C signal throughTEA6415C, and transferred into ITU601 through ADV7401, then send into Video-audio process chip Generation9. Tuner output SIF audio signal to MSP3450G to process, amplify, then put in D-type amplifier TA2024.
