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

Progress Acquired TV and IR cable
Made draft specifications
Scheduled to meet with client every two weeks
Website has been started
What We are Going to Do Turn in specifications and schedule to sponsor
Get C++ software
More research on infrared pulse signal
Add more updates in our website
Sketch schematic layout of the software
