Is earc hdmi2.1?
yes.
The "e" in eARC stands for Enhanced (Audio Return Channel), a new standard feature of HDMI 2.1 designed to deliver the best audio resolution through your TV. The new configuration requires eARC support from your TV and audio devices, which means your devices must support HDMI 2.1 - older HDMI versions do not support eARC.
With eARC, full-resolution sound signals (including 3D surround sound formats like Dolby Atmos and DTS:X) can be passed back and forth to your TV and audio system. This is true whether it's from an over-the-air broadcast, an internal streaming app, or a Blu-ray player or game console connected directly to an eARC-enabled TV.
Previously, decoding high bitrate audio like Dolby Atmos usually required plugging the source device directly into a compatible audio/video receiver, soundbar, or powered speakers, as most TVs were limited to outputting compressed surround sound or even stereo audio.
Using eARC, you will be able to plug your HDMI device directly into your TV, which will then send uncompressed, high-quality audio directly from the eARC port to your soundbar, receiver, or amplifier. What's more, since the HDMI 2.1 specification will provide faster data transfer and higher bandwidth, both audio and video signals can be automatically synchronized. Have you always had issues with lip sync? These issues will become a thing of the past with eARC.
In theory, this new agreement also means manufacturers can create a new wave of audio-only receivers, soundbars and amplifiers as your TV is able to handle the video signal while still allowing for the highest quality where the audio goes into your sound system.
This can significantly reduce the cost of various home theater components. Obviously, it'll be a while before eARC is everywhere, but when it's here, we'll enjoy a new level of simplicity and flexibility. With this in mind, it is important that we point out that it will take time for new technologies to become widely available.
Don't put off buying that new receiver or 4K HDR TV you've got your eye on. HDMI 2.1 is a very forward-looking, future-proof technology, but it's still in its infancy, and while a very small corner of the world is already enjoying 8K content, most of us are still waiting for 4K content to be fully integrated into our setting.
