Techniques and mechanisms for determining an operation mode of an audio-video (AV) device. In an embodiment, communication logic of the AV device may be configured at different times for different ones of a plurality of operation modes including an AV source operation mode for providing AV information to another device and an AV sink operation mode for receiving AV information from another device. In response to a detected event, control logic initializes the communication logic of the AV device into a default mode which prevents operation of the communication logic as an AV source.
