Introduction Toshiba created a new model HDTV

Toshiba H93 Digital Integrated TV

Special feature: uses infrared blaster outputs

Project Goals To verify that the TV is outputting the

correct IR signals.

Test the signal output from the IR blaster using a C++ base program

Deliver lab test gear package for Toshiba with software and operational manual

Signal Flow Remote control sends

signal to TV TV sends square wave

signal to other devices For this project, we

are only interested in the signal from TV to other devices

G-LINK

TheaterNet

Approach Set up connection

from TV to CPU through IR cable

Design a program using C++ language that has two modes:- Creating database- Testing mode

Approach (cont.) Creating Database:

for each button on TV remote control, software will sample the signal output by TV

samples will be stored in a database

Approach (cont.) Testing mode:

operator will select a sequence of signals from database

operator will drive TV to send signals to the software

software will output the pass/fail results

Input Output (I/O) Board NI PCI-6533 (DIO-32HS)

High-Speed Pattern I/O

and Handshaking A data acquisition board

that have input and output function

Convert electric signal into binary data
