New DVD Recorder With 52 hours Of HDD Recording Time

BlueQuark writes "I thought that this is cool. Everybody needs one. When I was liviving in Tokyo about a year and a half ago, Pioneer just released a DVD Recorder, which was quite nice. Now it looks like Panasonic will have one that does 52 hours. It's about 200,000 yen or about $1709.00 @ 117.76Tokyo's Y/$ rate. The blurb is a bit short, but can be found here. Or here is a more complete press release which is at Matsushita's site."

With Divx running at Quantizer 2 (Which mean compress it as little as possible, a.k.a.: Highest quality), The bandwidth used is about 2-3 Mbaud. If you use AC3 Audio, the bandwith for that is 192Kbaud - 384Kbaud. So, a maximal estimate would be 3456Kbaud. That's 432 KB/sec. A Single sided/single layer DVD holds about 4GB. 4GB / 432KB = 9709 sec = 161 min = 2.7Hours. Interesting... works out to about the same as a good length (but still ugly) VHS tape.

If you make it double sided, It goes up to 323min/5.4hr. If you can manage to make it record Double-sided, double-LAYERed, you'll get 647min/10.8hr.

Mind you, these are excessive estimates. This would be visibly lossless encoding (not lossless, but you wouldn't be able to tell). It rarely gets up to 3MBaud when you're encoding regular video. 1.5MBaud would be very much sufficient. Use that for the numbers and you can pretty much double it.

Number of minutes:
HQ BQ (High/Best)
SS: 323 161
DS: 647 323
DD: 1294 647

So, at HQ/DD you get 21.5hrs.
