HDMI 2.0 a/b ARC upgrade to eARC for Dolby Atmos and DTS:X Bitstream

HDMI 2.0 a/b connections and cables can manage up to 18Gbps bandwidth A/V signals. Despite this hardware great capability, the ARC function is limited to just 1 Mbps bandwidth. So, due to this "not hardware related" limitation, currently there is NO WAY to passthrough audio bitstream signals such as Dolby True HD/Atmos and DTS HD Master Audio/:X via ARC. By the way, users of the last generation consider lossless audio an important feature, because Dolby True HD/Atmos and DTS HD Master Audio/:X sound formats are becoming more and more important on the market. Today, you can purchase a latest generation Smart TV with integrated streaming services apps (e.g. Netflix, Plex, etc.) and a lastest generation external AVR or Soundbar, both capable to play and decode UHD HDR video with Dolby Atmos/DTS:X audio. But if you connect them, in order to enjoy the full capability of these lossless object based audio soundtracks, YOU CAN'T!!! But the only way is through HDMI ARC... We now already know that HDMI 2.1 version (that is NOT yet available on the market) will have an improvement for the ARC, called eARC. This new version will support the most advanced audio formats and highest audio quality due to an increase bandwidth up to 38 Mbps (8 channels, 192 kHz, 24 bits). So, considering the HDMI 2.0 a/b hardware potential, the huge numbers of devices with this connection already sold and that the HDMI 2.1 will be availble only next year just for new devices, HDMI Licensing LLC should provide a firmware update for the current HDMI 2.0 a/b users that implement eARC, upgrading the current ARC. Otherwise, you will be forced to replace all your latest generation electronics just to enjoy a function that could be already managed by your current hardware... Thanks for signing!
