Hi
Following great success of my previous topic - and by that I meant I learned something new and valuable, I'm going to ask another basic question that I have problem to get answer for.
Remember that I'm asking all of this in context of Kodi and media players that are used to play...well...media with Kodi.
I can highlight three ways of making my sound system generate sound waves commonly known as audio:
Ad 1. Bitstream - used when each bit of audio data is send to the receiver without altering it in any way. That means when something is encoded in TrueHD it should be delivered this way.
Ad 2. Passthrough - this one decompresses audio for further processing but the PCM signal can already be send to the receiver at this point. But what kind of signal this is? Analog or digital?
Ad 3. Decode - if the previous one uses digital passthrough then this one would convert digital to analog and send that signal to the receiver.
My goal is to find out not only if there are devices that support bitstream but also if I need bitstream at all. Because maybe passthrough will be enough? I've seen advanced settings in Kodi and they all says 'passthrough'. I didn't find even one mention about bitstream and Kodi. Is that mean Kodi doesn't support this kind of data transfer? Or maybe Kodi supports it and just there are no devices that supports it? It's important for me because I have AV Receiver that can work with most codecs so I would like it to take decoding part. Is there any differences between bitstream signal and digital passthrough in terms of quality? Or maybe there isn't' anything like digital passthrough?
Yeah...that's a lot of questions. But all of them arisen after reading forums looking for my perfect media player.
