Patent ID: 7277815

Claim:
A test interface card, for use in a test host without a hot plug function, said test host adapted for implementing testing of an audio-video device without shutting down said test host; said test interface card comprising: a Bus power control circuit; a microcontroller, adapted for sensing a control status of said Bus power control circuit and transmitting a sensing result to said test host; a PCI slot; a PCI Bus, connected to said microcontroller and a PCI slot of said test host; wherein said Bus power control circuit is adapted for controlling a power supply to said PCI slot and said PCI slot is adapted for connecting with said audio-video device; and a switch, for controlling and emitting an on/off signal to said Bus power control circuit for selectively cutting off the power supply to said PCI slot so that testing of said audio-video device can be implemented without shutting down said test host.
