A device may include a video camera for capturing a video clip, a processor, a transmitter, and a receiver. The processor may be configured to receive, from the video camera, the video clip that is shown on a display screen of a content presentation device. The transmitter may be configured to send the video clip or a fingerprint of the video clip to a remote device. The receiver may be configured to receive, from the remote device, an identity of content whose fingerprints match the fingerprint.
