I thought for sure this would be the year we would see a proliferation
of Blu-Ray stand-alone recorder/player units for the home. It has not
happened. Why is this technology being held up? Thanks |

'Cuz it ain't easy to real-time encode Blu-ray? Even standard-definition
DVD recorders often do an inferior (and lower than standard DVD
resolution) job of recording real-time. There is a reason transcoding
files on a fast computer still takes considerably longer than real-time.
You get better results with variable bit rate, dual-pass encoding using
the format's full true resolution.

AVI's avivo transcoding software does a commendable job of
encoding one-pass, on-the-fly h.264 from an HD MPEG2 source in
less than play time on a meager PC (AMD 3800). Since SA
recorders are meant to capture TV, I see no reason that this
could not be done directly from HDTV and written in a Blu-Ray
structure without any unique hardware. The target disc could
even be a DVD, as the h.264 file will actually be smaller than
the MPEG2 file by a considerable margin.
If, OTOH, you mean that recorders will not be made to capture
Blu-Ray sources and make Blu-Ray discs from it, that's not a
technical challenge, it's a legal one. |
