HDMI 2.1 eARC Future Proofs and Significantly Improves Home Theater Connectivity
The new release of the HDMI 2.1® specification featuring the Enhanced Audio Return Channel (eARC) technology offers immediate availability of a self-discovering, self-configuring, and fully automatic HDMI audio link for flawless home theater connectivity. As the first HDMI 2.1 eARC audio receiver and transmitter devices, eARC future proofs and significantly enhances home theater connectivity with this new, simple and trouble-free audio feature.
HDMI 2.1 eARC offers:
- Future Compatibility – eARC is the only way to ensure that an audio device will be fully compatible with future HDMI 2.1 televisions.
- Simplicity – eARC makes home theaters easy to use.
- Improved Performance – Delivers all of HDMI’s high bitrate home theater audio formats, including DTS:X and Dolby Atmos.
The eARC feature makes the audio device work seamlessly with the TV by allowing the devices’ selection and volume control to be performed through the TV remote, as if no audio device were attached. eARC uses two pins within the HDMI cable – the same pins intended for the HDMI Ethernet Channel feature – to transmit the low-jitter, high-bandwidth audio, and also bi-directional communication signals, which discover and control the audio feature. This is a significant improvement over old TOSLINK and SPDIF audio outputs, which require a separate cable and connector, and lack the ability to communicate between the audio device and TV.
