Hauppauge ATSC tuner

Now that multi-view is working, I am kicking myself for only have the 2-stream HDHR. So, I had an old Xbox Hauppauge ATSC tuner sitting in the electronics junk drawer that I thought I'd put to work.

The setup is basically four parts (running on Ubuntu):

1. Tuning the Hauppauge stick with dvbv5-zap so /dev/dvb/adapter0/dvr0 outputs the raw transport stream.
2. Piping that stream into ffmpeg, which repackages the selected video+audio PIDs into segmented .ts files and a rolling .m3u8 playlist.
3. Serving those files via nginx (I swapped out my quick Python http.server once it worked) so the HLS playlist is available at something like http://192.168.x.x:8042/stream.m3u8.
4. Persistence: wrapped the whole thing in a systemd service so the tuner+ffmpeg pipeline comes back up automatically after reboots.

Right now it’s locked to one channel (NBC), but it’s smooth and stable. Next step is making it on-demand, where requesting abc.m3u8 or fox.m3u8 would tune the right frequency and spin up ffmpeg dynamically.

yes I know it's silly and uses a lot of resources, but hey this is called playground!

I did go ahead and setup TVHeadend as the primary driver of the tuner since it will only spin up when its called -- not all the time like my original setup.
