Finalise
A process that makes play of a recorded CD-R, CD-
RW, DVD-R, etc. possible on equipment that can play
such media. You can finalise DVD-R, DVD-R DL,
DVD-RW (DVD-Video format), +R, +R DL on this unit.
After finalising, the disc becomes play-only and you
can no longer record or edit. However, finalised DVD-
RW can be formatted for recording again.
Formatting
Formatting is the process of making media such as
DVD-RAM recordable on recording equipment.
You can format DVD-RAM, DVD-RW (only as DVD-
Video format), +RW, SD cards and the HDD or
R and +R DL on this unit.
Formatting permanently deletes all contents.
Frames and fields
Frames refer to the single images that constitute the
video you see on your TV. Each frame consists of two
fields.
≥
A frame still shows two fields, so there may be some
blurring, but picture quality is generally better.
≥
A field still shows less picture information so it may
be rougher, but there is no blurring.
HDMI (High-Definition Multimedia Interface)
Unlike conventional connections, it transmits
uncompressed digital video and audio signals on a
single cable. This unit supports high-definition video
output [720p (750p), 1080i (1125i), 1080p (1125p)]
from HDMI AV OUT terminals. To enjoy high-
definition video a High Definition compatible TV is
required.
JPEG (Joint Photographic Experts Group)
This is a system used for compressing/decoding
colour still pictures. If you select JPEG as the storage
system on digital cameras, etc., the data will be
compressed to 1/10–1/100 of its original size. The
benefit of JPEG is less deterioration in picture quality
considering the degree of compression.
LPCM (Linear PCM)
These are uncompressed digital signals, similar to
those found on CDs.
MPEG2 (Moving Picture Experts Group)
A standard for efficiently compressing and expanding
colour video. MPEG2 is a compression standard used
for DVD and satellite based digital broadcasting.
MPEG-4 AVC/H.264
A standard for efficiently compressing and expanding
colour video. MPEG-4 AVC/H.264 is an encoding
method used for recording of the High Definition
videos.
MP3 (MPEG Audio Layer 3)
An audio compression method that compresses
audio to approximately one tenth of its size without
any considerable loss of audio quality.
