In this model, the following new functions and specifications
have been included in addition to those of conventional models:
1. Improved multitasking functions
As both the HDD and DVD drive are mounted in this model, like
conventional models, the unit is designed to support various
multitasking. Furthermore, this model supports DVD multitasking
(only in VR mode), which was impossible with conventional
models.
a Pursuit playback
Playback of the title being recorded by the DVD drive in VR
mode or the HDD is supported.
b Simultaneous recording/playback 1
Playback of a title other than that being recorded by the DVD
drive in VR mode or the HDD is also supported.
c Simultaneous recording/playback 2
DVD playback during HDD recording is supported.
d Simultaneous recording/playback 3
HDD playback during DVD recording is supported.
e Recording during high-speed dubbing
HDD recording during high-speed dubbing from the HDD to a
DVD is supported.
f Playback during high-speed dubbing
Playback of an HDD title during high-speed dubbing from the
TE
L 13942296513
HDD to a DVD is supported.
2. Improved dubbing functions
High-speed dubbing and normal-speed dubbing are supported, as
with conventional models. A one-touch dubbing function that
enables automatic selection between these dubbing functions is
also provided. In this model, high-speed dubbing from a DVD (in
VR mode) to the HDD is also an added capability.
3. Disc backup
The function of creating a backup disc for a disc recorded in
Video mode is added. The data of the original DVD are
transferred to the HDD, then retransferred to the DVD drive, and
because no reencoding is required during data transmission
between the drives, a backup disc with no degradation of video
and audio signals can be created.
4. Advanced disc NAVI
In the conventional disc NAVI function, recorded titles are
displayed with still pictures as a list. In the advanced disc
NAVI function, the title selected with the cursor is displayed
as an animated picture with sound.

5. Improved Still Picture menu in Video mode
The disc NAVI function, which enables displaying a list of
recorded titles with still pictures, is enabled in Video mode
with this model. Selection from among nine title menus is also
supported.
6. Adoption of MPEG2 SIF
In MN1-6 modes, MPEG2 SIF has been adopted, instead of the
MPEG1 SIF of conventional models. This enables higher-quality
recording for longer hours.
7. Improved editing functions
For DVD, the original/play-list editing in DVD-VR mode
available with conventional models is provided.
For HDD editing, play-list-editing functions almost the same as
for the DVD-VR, such as title combination, separation, and
partial erasure, are enabled for the HDD with this model. With
conventional models, these edit functions are available only for
the dubbing list. The automatic-chapter-mark-insertion function
in response to a change in audio type (stereo, monaural,
bilingual) makes commercial-cutting editing easier.
8. Various-format playback
Playback of WMA, MP3, and JPEG formats is supported.
