Abstract
Apparatus, systems, and methods are disclosed for cancellation and content recognition of audio received over a High-Definition Multimedia Interface (HDMI)/Audio Return Channel (ARC) port of a display device. The media device receives audio over the HDMI/ARC port from the display device, processes the audio by identifying, decoding, re-encoding, and fingerprinting the audio with identification information, and subsequently streams the audio within the media streaming environment, including to external speakers, such as voice-enabled speakers. Based on the identification information and recognized content of the processed audio, the media device offers additional content for streaming to a user. The media device continuously monitors for spoken voice received over a voice-enabled speaker while the media device simultaneously receives, processes, and streams audio from the display device. By cancelling the part of the streaming audio received simultaneously with the spoken voice received, the media device enables the voice-enabled speaker to distinguish a voice command.
