Protocol independent remote controller emulator for automated testing of multiple DTV/STB

This paper proposes a new scheme for DTV/STB remote controller emulator (RCE), which enables automatic control of the DTV/STB devices under test from independent test hardware/software platform. Specifically, the proposed RCE sets the DTV/STB device in particular state within the automatic functional verification system during the test procedure. Besides, it has the ability to record the remote controller (RC) commands sent to the device (history of commands sent by the user), which can be used for debugging the DTV/STB devices when their functionality failure is detected. The proposed RCE is neither dependant on the RC nor the DUT.
