[QUOTE="Pleo, post: 1058435817, member: 8708"] Είναι πολύ δύσκολο να ξέρει κάποιος αν το ARC είναι Common Mode ARC και πως αυτό έχει γίνει implemented στα δύο μηχανήματα, καθώς και ποια S/W upgrade μπορεί να έχουν δώσει τη δυνατότητα αυτή. "Common Mode ARC is superior, but less common (excusing the pun) in terms of deployment. It's still based on the same S/PDIF spec, but can theoretically support up to around 12Mbps. This is enough to carry 24-bit 192kHz 2-channel audio, or - to the point of this blog - a Dolby format called E-AC-3, which we know better as Dolby Digital Plus. This can also carry Metadata-enhanced Audio Transmission (MAT), being audio objects; aka Atmos. So existing HDMI ARC can potentially support Dolby Atmos by maxing out the Common mode capability with an MAT stream. But there's a huge catch. Two, actually; Channel count & resolution - while E-AC-3 can support up to 15.1 channels of audio, it's well beyond the HDMI ARC spec. Even getting 7.1 channels to pass is a stretch, so even if the stream contains object metadata, it will lack the resolution and height speakers. System support - getting Atmos to work through HDMI ARC requires Common mode support in both the TV and AVR, and a high integrity link in-between. Even then, performance will be marginal."
