1. What are HDMI ARC and eARC?
HDMI ARC and eARC are both features of HDMI. ARC stands for “audio return channel”. It allows a single HDMI connection to be used as both an input and an output, which eliminates the need to use a dedicated audio cable to connect a soundbar or AV receiver to your TV. HDMI ARC can provide a two-way flow of audio between your TV and audio system via just an HDMI cable. It can be one of the best home theater features, as it can reduce cable clutter, save more cost and simplify your home theater setup.
eARC stands for “enhanced audio return channel”. As its full name implies, it has made some improvements on ARC, able to stream more complex multichannel formats, like Dolby TrueHD and DTS:X.
2. What are the main differences between HDMI ARC and HDMI eARC?
HDMI eARC is the next generation of ARC. Its main advantage lies in a big boost in bandwidth and speed, as it allows you to transmit higher-quality audio from your TV to a soundbar or AV receiver. With its 37Mb/s bandwidth, eARC can carry up to 32-channel audio, including 8 channels of 192 kHz and 24-bit uncompressed audio. It also supports modern advanced audio formats like DTS-HD Master Audio, DTS:X, Dolby TrueHD, and Dolby Atmos.
In comparison, HDMI ARC only supports up to 6-channel compressed audio and has a maximum bandwidth of 1Mb/second. It supports different audio formats like PCM (2 channel), Dolby Digital (up to 5.1 channel) and DTS Digital Surround (up to 5.1 channel).
