Well, you can bet any implementation of DTS:X over streaming will be lossy to start the way Dolby Atmos still is over streaming. Interesting to see IMAX Enhanced and DTS finally making some real noise. Reminds me of the 90's when THX DTS laserdiscs were the thing for getting the ultimate movie watching experience in the home.
I support this argument that it is lossy DTS if played from TV's internal app. Let's stop and consider a few bits.
It must be loosy, unless MediaTek has finally designed TV chipset that can natively output lossless audio via wider eARC channel from internal apps. No TV can do this at the moment, hence all current TV apps output lossy Atmos via HDMI eARC. Is there any new SoC that those TVs use? I cannot see any MediaTek SoC for TVs that has native eARC build into boards, which is fundamental for any lossless soundtrack played from internal apps via HDMI.
Increase in streaming bandwidth is a marketing gimmick that distracts. WiFi 5 is several times faster than 115 Mbps and most TVs have it. HDMI 2.1 port is not necessary for those movies. Those movies have to fit into 18 Gbps pipeline, so HDMI 2.0. Apps might support lossless audio in software, but if TV's chipset does not support it in hardware, lossless audio cannot go out via HDMI. In the TV spec on Sony's website, I cannot see DTS:X mentioned anywhere. Am I missing something?
It reads: "It uses DTS Sound with its own
optimized version of the DTS:X codec". What does this really mean?
