What is “ARC”?
ARC stands for Audio Return Channel.
It is a feature in HDMI connections. It lets a TV send sound back to a soundbar or home theater system through one HDMI cable.
This means you do not need an extra audio cable.
History of ARC
ARC was introduced in 2009 as part of HDMI 1.4. Before ARC, people often used separate audio cables to connect TVs and speakers. This made setups messy. ARC solved this problem by allowing sound to travel through the same HDMI cable already connected to the TV. Many TV makers quickly adopted ARC because it made home entertainment systems easier to use. Today, ARC is still found in many TVs, soundbars, and audio systems around the world.
What is “eARC”?
eARC stands for Enhanced Audio Return Channel.
It is a newer and improved version of ARC.
eARC can send better-quality sound and support advanced audio formats.
History of eARC
eARC arrived in 2017 with HDMI 2.1. As movies and streaming services started using better sound formats, ARC became limited. eARC was created to handle larger audio files and deliver higher-quality sound. It allows users to enjoy advanced surround sound and lossless audio. Today, many modern TVs, gaming consoles, and premium sound systems include eARC because it offers a better audio experience than standard ARC.
