(Content Protection once’ broadcast programs. CPRM stands for Content Protection for Recordable Media.
for Recordable Media) This Recorder is CPRM compatible, which means that you can record copy-once broadcast
programs, but you cannot then make a copy of those recordings. CPRM recordings can only be
made on DVD-RW discs formatted in VR mode or DVD-RAM discs, and CPRM recordings can

Laboratories. It is the common version containing up to six discrete channels of sound, with five
channels for normal-range speakers.
Down-mixing This is the process of remixing the multi-channel audio found on some discs into two channels. It is
useful when you want to listen to the 5.1 – channel audio recorded on DVDs through your TV’s
speakers. Some discs prohibit down0mixing. If this is the case, this unit can only output the front two
channels.
Dynamic range Dynamic range is the difference between the lowest level of sound that can be heard above the
noise of the equipment and the highest level of sound before distortion occurs. Dynamic range
compression means reducing the gap between the loudest and softest sounds. This means you
can hear dialog clearly at low volume.

(Joint Photographic system on digital cameras, etc., the data will be compressed to 1/10-1/100 of its original size.
Experts Group) The benefit of JPEG is less deterioration in picture quality considering the degree of compression.
Letter Box Letterboxing is the practice of transferring widescreen film to video formats while preserving the film's
original aspect ratio. Since the video display often has a square aspect ratio, the resulting
videographic image has black bars above and below it. Letterboxing was for use in 4:3 television
displays when widescreen television was in its technologic infancy.
