This is the sort of thing that could be included in the XML format. If for instance you had a temperature sensor calibrated against a standard in a Telarc registered lab, the lab could provide along with the calibration certificate a digital certificate that could authenticate the sensor.
If people buying HDTV's already have PVR's then I'm sure they would'nt settle on an HDTV that couldn't talk to their PVR. The market for HDTV's is small because of their price, with digital controls in place the market would shrink further.
