Database Mode Panel
This project designed a piece of automated test equipment that will receive IR signals from the H93 television set, compare them against a known good pattern, and graphically display the results for each control signal tested
Toshiba’s goal is to achieve100% test coverage on all products.
For the new H93 integrated TV, Toshiba does not test the remote control of third party DVDs and VCRs. This capability is called “IR Blaster”.

The H93 television outputs infrared signals using a device called “IR blaster”
With the IR blaster, external devices, such as DVD and VCR players can be connected to the TV and can be controlled using the H93 remote control

Conclusions
This capability can be successfully used to test device for the IR Blaster
The test program ensures that the signal that is transmitted from the TV to external devices has the correct characteristics, and that the TV performs the right task for every signal received

Database Mode
The output signals from the television are sampled and analyzed, and their characteristics stored in a library
Test Mode
Allows the user to capture the signal from the H93 TV under test, and compare it with a signal from a library created in the Database mode.
Pass/Fail results are logged locally.
