Abstract

Provided is an apparatus, method, and computer-readable recording medium for analyzing audio/video (AV) output, capable of automatically analyzing an AV output of a sink device. The apparatus for analyzing an AV output includes: a transmitter configured to transmit a high-definition multimedia interface (HDMI) signal generation command to a source device such that an AV screen is output on a sink device; a receiver configured to receive, from a user terminal, data of a mirroring screen corresponding to the AV screen being output on the sink device, and a controller configured to perform analysis by comparing the received data of the mirroring screen with reference data stored in a memory to analyze a responsiveness for a HDMI signal of a HDMI port provided in the sink device.
