Basic Blu-ray Disc CharacteristicsLarge recording capacity up to 27GB
27GB of data is enough to put 2.5 Hours of HDTV recording on it. This is more than enough for any average hollywood movie.
It also can record over 13 hours of standard TV broadcasting using the VHS/standard definition picture quality, 3.8Mbps.
High-speed data transfer rate 36Mbps
Because of its high speed transfer rates it can also record the data in very little time. In a perfect environment it would take about 2.5 hours to fill the entire BD with 27 Gigabytes of data. More than enough transfer capacity for real-time recording and playback. Mind you that this in single speed writing and reading !
The CD-rewriters of todays on CD-ROM are 48 speed, which of course is faster than the Blu-Ray single speed standard, BUT it wold take more than 40 (!) CD-R's to record 27 Gigabytes. It would take more than 80 minutes to record or read the data without counting the time you need to change all those 40 dics
In addition, by using the random accessing functions on the BD recorder , it is possible to edit video data captured on a video camera or play back pre-recorded video on the disc while simultaneously recording images being broadcast on TV.

I thought there were so little reactions, I felt compassion with Mr. Belvedere. So once again: nice article.
Ok. Great article... but... Why are they using MPEG2? We live in a world where MPEG4 has taken over(divx). All they need to do is creat a MPEG4 for super high resolutions(1080p).
Same with audio. By that time we will have DD10.2 or something like it. Audio should be encoded in WMA8(divx audio) or MP3PRO.
