MiniDVDs are particularly suitable for playing on the computer. For stand-alone
devices they must be tested on an individual basis as to whether the device can
handle the DVD format on a CD-ROM.
AVCHD disc
Use this format to create a high-resolution video. You can burn Blu-ray (BD-R/RE)
blanks as well as conventional DVD±R/RWs. In contrast to Blu-ray Discs (view page
350), MPEG-4/AVC codec (view page 354) is applied as the video format, which
requires less memory at a c
omparable image quality.
Compatibility
AVCHD disc on Blu-ray blank: Since this is a BD-conformant format, the disc created
can be played back in any conventional Blu-ray player. Playback problems can almost
always be traced to incompatibilities between Blu-ray blanks and Blu-ray players. In
this case, consult the instructions for your Blu-ray player or ask the manufacturer
which blanks are compatible with the device.
AVCHD disc on DVD blank: The DVDs created with AVCHD video are not supported
by all Blu-ray players. The behavior of the devices is quite different. Normal DVD
players cannot replay AVCHD discs, since the AVC format is not supported.
Blu-ray Disc
Since early 2008, Blu-ray Discs are viewed as successors to DVDs and offer
especially high storage capacity of up to 27 GB in a single layer (double-layer up to 54
GB) with very few write errors.
The term Blu-ray Disc comes from the blue color of the laser. Because a color cannot
be registered as a trademark, the letter "e" was removed from the word "blue".
The high storage capacity of the Blu-ray Disc suits high definition videos and
slideshows in high quality perfectly, since these are characterized by large file sizes
(depending on material approximately 40 MB/sec) and very high memory use. The
MPEG-2 codec is used to create video.
Companies that were involved in developing Blu-ray technology have united
themselves into the Blu-ray Disc Association (BDA).
Blu-ray Discs come in three varieties:
• Only readable BD ROM (comparable to DVD video),
• rewritable BD-RE (comparable to DVD±RW or DVD-RAM),
• and as a disc that can be written to only once BD-R (comparable to DVD±R).
