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 unused +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 television. Each frame consists of two
fields.
Frame Field
≥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.
Gateway
IP address of the electronic device providing Internet
access.
Usually called a router IP address. (e.g., 192.168.0.1)
HDD (Hard disk drive)
This is a mass data storage device used in computers, etc.
A disk with a surface that has been treated with magnetic
fluid is spun and a magnetic head is brought in close
proximity to facilitate the reading and writing of large
amounts of data at high speed.
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
television is required.
IP address
A set of numbers which distinguish each PC on the network
when, for example, connected to the Internet. When using a
PC in a LAN to access a PC or device that is not included in
the LAN, the IP address is called the local IP address. (e.g.,
192.168.0.10)
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.
LAN (Local Area Network)
A group of linked devices in a company, school or home.
Indicates the boundaries of a particular network.
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.
Field
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.
