D-VHS
By utilizing the characteristic of the tape media, video
and audio data compressed using MPEG2 method can
be recorded at high-speed rate and in high volume.
Bit stream recording*1 method is employed to record
inputted MPEG2-TS signals (signals with additional
information such as program assignment for service
access other than MPEG2 video and audio data) directly.
This unit is equipped with MPEG2 encoder/decoder*2
that enables digital recording and playback for analog
signal (this unit supports only NTSC signal).
In addition, a vast amount of VHS analog recording
images can be playbacked. This is D-VHS.
This unit has the feature to record and playback S-VHS
and S-VHS ET as well.
*1 Bit Stream Recording
Bit stream recording is a method to record the MPEG-TS
signals compressed by MPEG2 on the tape directly and
output the same type of signals.
This unit enables recording and playback of high
definition MPEG2-TS signals at a high speed HS mode of
28.2 Mbps.
*2 MPEG2 Decoder
This unit is also equipped with MPEG2 decoder to
decode the MPEG-TS signals and output analog Y/Pb/Pr
during playback.
When decoding MPEG-TS signals recorded at 720/30P,
the signal will be converted to 720/60P that is generally
used.
Linear PCM Audio
Conventional D-VHS recording uses MPEG-1 Layer 2
compression to record analog audio digitally.
For recording without compression, this VCR also
features PCM recording (pulse code modulation: 48 kHz,
16-bit, 1536 kbps).
Used with high-resolution HS/STD mode, it offers
outstanding high-fidelity recording and playback.
(Recording from audio input alone is not supported.)
Dolby Digital
A form of digital audio coding developed by Dolby
Laboratories to deliver surround sound with 5.1 channels
(front left and right, center, rear left and right, and a
channel for LFE (low-frequency effects).
When you play back a digital tape encoded in Dolby
Digital format, the Dolby Digital bistream is sent from
the DIGITAL OUT OPTICAL connector.
Set “OPTICAL OUT” to “Dolby D” (墌 page 37).

i.LINK
i.LINK is a digital serial interface that allows devices
equipped with an i.LINK connector to exchange digital
video signals, digital audio signals, and device control
signals bi-directionally over a single cable.
i.Link refers to the IEEE1394-1995 industry specification and
extensions thereof. The logo is used for products compliant
with the i.Link standard.
MPEG2
Abbreviation for Moving Picture Experts Group, Phase 2.
Unlike previous compression methods, MPEG-2 uses an
extremely efficient compression method that supports
high-definition video. Based on the principle that much
video data remains unchanged from one frame to the
next, predictive coding is performed to eliminate
redundant data.
Specifically, compression is applied between frames
(based on the correlation of frame data) and within
frames (based on DCT, or discrete cosine transform) for
an extremely efficient compression technique.
