EARC

HDMI eARC Carries TV Audio Back to Sound Systems

A television often sits at the center of several audio sources. Built-in streaming apps generate sound inside the TV, while game consoles and media players can send both video and audio into its HDMI inputs. An external soundbar or receiver then needs a route for that audio. HDMI Audio Return Channel provides such a route. Its enhanced form, eARC, expands the audio formats and data rates that can travel from the television back to compatible audio equipment.
