An audience measurement computing system for monitoring a media presentation device in a monitored environment is described and includes a network interface, at least one processor, and a non-transitory computer-readable medium comprising instructions executable by the processor(s). The computing system is configured to obtain, via a cable connected to an input port of the media presentation device, a voltage signal generated by the media presentation device based on an operational state of the media presentation device; compare voltage indicated by the voltage signal to a threshold; based on the comparing, generate timestamped operational state data comprising a record indicative of when the media presentation device is in an on-state; obtain audience measurement data representing one or more media signals communicated to the media presentation device; and transmit, via the network interface over a network and to a central facility, the timestamped operational state data and the audience measurement data.

Methods and systems to monitor a media device via a USB port

A disclosed example apparatus to monitor a media device includes: an input to obtain a signal at a universal serial bus port of the media device; and a bit rate comparator to: determine the media device is involved in a data transfer if a bit rate of the signal exceeds a threshold; and determine the media device is not involved in the data transfer if the bit rate of the signal does not exceed the threshold.

Methods and systems are disclosed to monitor a media device via a universal serial bus ('USB') port. An example method includes obtaining a voltage output by a UBS port of the media device and determining if the voltage exceeds a threshold. If the voltage exceeds the threshold, the example method includes determining the media device is in an on state. If the voltage does not exceed the threshold, the example method includes determining the media device is in an off state.
