5.1 (6 channels) is most common for home theater (60%). 7.1 (8 channels) is less common (20%). Dolby Atmos (object-based) is rare (5%). Stereo is still popular (15%). Resellers see these layout preferences.
Here's the layout preference data. A British IPTV reseller analyzing audio layout usage discovers: 5.1 (60%), Stereo (20%), 7.1 (15%), Atmos (5%).
What actually works for resellers is offering 5.1 as the premium option and stereo as default. Atmos and 7.1 are niche.
I have a 5.1 system. British IPTV 5.1 content sounds great. My reseller offers it on most movies and live events.
The pattern that keeps showing up is that IPTV reseller UK operators with 5.1 support cater to home theater enthusiasts. Those with only stereo serve the masses.
Honestly, if you have surround sound, ask about 5.1 support. A IPTV reseller UK with 5.1 is worth it. Atmos is overkill for most.
That said, 5.1 requires more bandwidth. Expect higher prices.
In most cases, British IPTV 5.1 audio satisfies home theater enthusiasts. Atmos is rare.
