Arcam DV137 - Manual (Page 3)

ARCAM, Pembroke Avenue, Waterbeach, Cambridge CB5 9QR, UK www.arcam.co.uk
Preliminary information: Arcam’s policy is one of continuous improvement - we reserve the right to change any features without notice.
What’s a Vaddis 888s? Current DV78/79/29 models are equipped with Vaddis 5 core processor. DV137
uses the all new Vaddis 888s model. Arcam is the first company in the world to
implement this high end processor which is significantly more powerful and has
important feature advantages over the Vaddis 5.
How good is the picture? New motion adaptive de-interlacing techniques used in the Vaddis 888s mean a
cleaner, smoother picture than in Vaddis 5 equipped players.
Does the Vaddis 888s suffer from
Chroma Upsampling Error (CUE)? No. The DV137, unlike many other players, does not suffer from CUE. CUE is a
processing artifact which results when processing the 4.2.0 video on a DVD disk
into 4:2:2 video required for the video outputs. Results are jagged edges in the
picture particularly on highly colored objects when CUE is present.
Does it have a layer change delay? No. Picture and sound output from the DV137 will not be affected when the
player is changing from one DVD disc layer to another. This is because the Vaddis
888s implements much larger memory buffers than many other players.
What type of discs can it play? Is it
universal?
The Vaddis 888s reads the following disc formats: DVD-V. DVD-A, CD-DA, SACD,
DivX, CD-ROM, DVD+R/RW, DVD-R/RW, DVD-ROM
What type of discs can be played? The DV137 can play DVD Video, DivX, VCD, S-VCD,,
What video outputs are there? Connections are as follows: HDMI (with video scaling up to 720p, 1080i, 1080p
plus a custom resolution of 1366 x 768p), Component (480i/p, 576i/p), RGB
SCART, S-Video and “Always On” Composite video.
What is video scaling? Video scaling is the process of converting a picture with one number of lines to a
video picture with a different number of lines. This is necessary with modern
digital displays because they have a fixed number of lines of pixels and need to fill
all pixels to create a full picture. Scaling can be upwards (e.g. 480 line NTSC video
to a 1080 line display) or downwards (e.g. 1080 line video into a 768 line plasma
panel). The device that carries out this is referred to as a “scaler”.
Why a custom resolution of 1366 x
768p?
This format represents the most popular pixel array for plasma screens, LCD TVs
and digital projectors today. Although many of these displays do not allow direct
feed of this type of signal at present it is hoped that this will change. This will then
mean that the scaler in the DV137 will be able to send exactly the right type of
picture for the screen layout and bypass the inferior scaler fitted inside the display
completely.
What type of scaling does the
DV137 have?
The DV137 uses a brand new scaling IC called the ABT1010. ABT stands for
“Anchor Bay Technologies” which is a division of DVDO. The scaling processes
used are absolutely state of the art and are far better than those fitted into most
digital displays therefore, when the scaled output from the DV137 is used a better
picture will normally result.
What sort of video DACs does it
use?
The video DAC’s are 11 bit 216MHz devices from Analogue devices and are of
broadcast quality. There are 10 video DACs in total meaning all analogue outputs
can be active at the same time.
What sort of DVD drive does it use? The DV137 uses a new drive with a Sanyo dual laser pickup. The two lasers are
used (one for DVD & SACD, one for CD) as the data layer within the different
types of disc is in different places. Each laser is focused on a specific region to
ensure most accurate data retrieval.
What is “Always On” video output
all about?
To meet the requirements of the custom install market the DV137 has a dedicated
composite video and RGB SCART outputs which will always deliver a picture
regardless of what the other outputs are doing. This is ideal for distributing
pictures to multiple zones such as the Zone 2 feature on Arcam AV receivers and
processors.
