I'm building a media server to store my pics, movies and audio files. I want to be able to access/stream the stored content from/to several devices around my house (tablets, phones, laptops, PS3 and TVs) and I'm planning to do so by using any of the server software available (linux based plex, XBMC, pms, serviio, universal media server...). I think I have the streaming side covered: the server has an AMD A10-6700, 8GB RAM, 4 HDDs in RAID 10. It should be enough to transcode all the media stored to the different devices.
The issue I can't get solved is this: how can I stream HD audio/video to my Onkyo TX-SR805 receiver? I want to enjoy 7.1 audio (and of course Dolby Digital Plus, Dolby TrueHD and DTS-HD). My Onkyo receiver does not have any networking capabilities built in (it's a somewhat old model and I can't afford a new one right now), so I think that, unless I connect the server directly to the receiver (and stream through HDMI), I'll have to consider a HD media player and have it send the HD audio to the Onkyo. (I must point out that I don't know if I could connect the server to the receiver via HDMI since they're on different floors and, even if I can do it, will I have to run some sort of front-end media player on the server, turning it into a HTPC? How could I control it without having to use kb+mouse all the time? (Sure, I must use them for admin tasks, I don't want to carry a laptop all the time in the room) Maybe an Android App? Plex and XBMC comes to my mind since they have such apps.
About a media player: I was thinking about using something like a Roku to stream the content from the server to the receiver, but since it doesn't support HD audio it's useless for me. I was reading about the Mede8er MED600X3D and the KDLINKS HD700 but I don't know if those devices work with any of the server software...
Well, that's it. I hope I explained my doubts clearly. Any assistance anyone can provide would be greatly appreciated.
