I'm moving to a new country soon, and I've been considering setting up multiple DVB-T receivers to a low power computer to record all free-to-air channels simultaneously into a multiday looped buffer, to make available to myself over the internet. Where I live, the local free-to-air channels rarely have YouTube live streams, and when they do they only have around 12 hours of history at a measly 480p.<p>I have a bunch of those cheap RTL2832U USB receivers from a decade ago. I've played with Tvheadend before and the way DVB-T works is multiple channels are placed on a single multiplex, so you only actually need 5 tuners to receive 30 channels.<p>Traditional platter-style hard drives are cheap and well suited to such workloads too: so-called surveillance drives used for looping multiple days of security camera footage are available in 10+ terabyte capacities. I may re-encode given most broadcast TV where I live is broadcast in MPEG2 (used in DVDs) rather than better codecs like H.264 (used in Blu-Rays).<p>Anyone else do anything similar?
