In my home theater sys, I have a fancy receiver. All signals go to it, and it does all the switching and decoding, sending video-only to the projector. I understand it. Now, I'm looking to replace my 20-year-old bedroom system. I haven't paid attention to TV in a long time, and with all the changes in available gear I don't know what to get and how to connect, because I don't really understand what happens where. I'm planning to get an LG 55C8, and either a new receiver or a soundbar (maybe a Vizio Atmos?) So, some questions.
If I use a receiver, does it do the switching, or would I use the LG TV to do that? It seems like, if all signals go to the receiver directly, then it needs to do the audio decoding itself and just pass video to the TV.
If all signals go to the TV, which in turn sends to the receiver or soundbar via HTML ARC, does the TV decode the audio and just send the individual channel info, or does the receiver / soundbar still need to understand the difference between, say, Atmos and DTS and act accordingly?
Which hookup is preferable - receiver or TV doing the switching / decoding?
