722 spec question

[drmatsci]

Now I read somewhere that the 722 has a 500 GB hard drive in it?
And that the current satellite HD Mpeg4 is recorded at 4 GB per hour of recording. So if that is true, that's 500/4 or 125 hours of HD recording!!

But obviously a chunk of the hard drive is set aside for the 'on demand' programming. But how much is set aside? If our allowed recording is 50 odd hours of HD that leaves 70 hours of 'other' stuff like video on demand?

Is that right?

Not quite, the 50 hours listed is for mpeg2, not mpeg4. I recorded an mpeg4 movie lasting 2 hours and 22 minutes and I only use 57 minutes.

If you have the external hard drive (EHD) enabled you can plug in the USB drive and DVR-4-2 (send) to see the size in MB of each inactive (not recording nor being viewed) recording on your internal HD.

You will seldom get better than a factor of 2 better with MPEG-4 vs MPEG-2.

Yes, you did read it right - posted here.
Sort of - I did test non-stop writing MPEG-2 and MPEG-4 channels from empty disk up to the end of space - check it.
Size of the VOD partition [ ES_RESERVED] you can find in the thread. Or use Search for "ES_RESERVED", if you need more info.

Can't find my own posts regarding measuring space/time ratio, so reposting the tables here again.

So, in other words, MPEG-4 takes up half the space as MPEG-2 on HD? Is that true for SD as well?

 

[Smith P.]

I left the test for you - hope someone with EA sub could do that for MPEG-4 SD channel.

If you have an HD subscription with a 722 with the G3 card then can you pickup the channels off the 61.5 satellite? Is 61.5 the only one needed to pickup the content? Does 61.5 pick up just as many channels as the HD on 110 and 129?

I don't know what MPEG-4 SD channels on 61.5W. If those're on spot beams, the our side is out of luck - see my signals off 61.5W today.
