Atsc receiver error rate: 5.19e-05


#1

I thought this was pretty good for last night’s recording of
“Boston Legal”:

end of file, exiting
661 errors out of 12727848 mpeg packets. 12727187 good packets. Error
rate = 5.19e-05

That’s for a 450Kw xmtr 10 miles away receiving with a scanner antenna.

What works so far is: recording an hour long program in 3 20-minute
segments, making about 80Gb per segment. Then running gnuradio-0.9
on 3 cpu’s (with fake mc4020’s on another 3 cpu’s) and by about
10AM the next day they’re done. Then concatenate the 3 transport
streams into 1 8Gb file, and running hdtv2dvd on it for 2 hours,
and out pops one hour long 720x480 ntsc high quality dvd, all from
thin air.

Tonight’s target video: Bones.

As a side note, if you want to keep the program in HD you can burn the
MPEG program on a standard red-laser DVD and play them with this DVD
player:

You’ll have to burn it as a DL disc, but 8 MB would fit. You can also
encode it to WMV-HD or DiVX-HD to make the program much smaller.

This is all kind of stop-gap until we get HD-DVD and/or Blu-Ray. But it
is sweet to play HD content off a DVD.

Cool.

It’s too bad you have to downsample to 720x480 from 1920x1080 or
whatever it was you started with. Maybe you need to install MythTV?
