FAQs:
Q: What are these new 'Game Modes' ?
A: These modes can reduce the amount of video delay to less than a single frame. In many competitive processors the effects of applying complex algorithms to the video image results in upwards of a seven frame delay. This can inhibit the real-time performance for gamers who want instantaneous response to react to stimuli and to realize peak performance from their application. The VRS Precision Deinterlacing™ Game Modes will reduce frame delay down to slightly less than one frame of video.
Q: What comes on the DVD that ships VP50?
A: The DVD that comes with the VP50 includes many test patterns to assist the you in optimizing the setup and to evaluate the performance of your iScan VP50 (or any other video processing). This DVD was produced by Stacey Spears and Don Munsil (S&M) and I strongly believe that this will be the Reference DVD that everyone uses to compare video processing from now on.
The Static Patterns include:
Picture Controls (Brightness/Contrast, Color/Tint, Y/C Delay, and Resolution)
Geometry (Frame Geometry, Image Cropping, Cross Hatch - Coarse, Cross Hatch - Fine, and Focus)
Gray Scale (10IRE - 100IRE Windows and Gray Ramp)
Half Patterns (Black/White, Color 7 Bars 75, Color (7) Bars 100, Color (8) Bars 75 and Color (8) Bars 100 - These are the 'other half' of the test patterns which are built into the iScan VP50)
The Motion Patterns include:
Chroma Upsampling (ICP, 2-2, and 2-3)
Source Adaptive (Film, Film Detail, and Synthetic Wedge - Each test patterns has 2-2, 2-2-2-4, 2-3-2-3, 2-3-3-2-2, 2-3-3-2, 3-2-3-2-2, 3-3, 4-4, 5-5, 6-4, 8-7-8-7 cadences as well as a sped up cadence and bad-edits)
Edge Adaptive (Jaggies at 45/20/10 degress, Jaggies at all degrees, Video sequences which have very difficult diagonals: 'Ropes', "Ship' , 'Hockey', and Bridge')
Mixed Mode (Horizontal Text and Vertical Text)
Montage
There is also a Demo Loop which goes through all of the deinterlacing evaluation content.
The Source Adaptive 'Film' and 'Film Detail' content should be familiar to everyone, they are the infamous Cafe scene (ever wonder what happens after the bum gets the newspaper?) and Super Speedway, respectively.
Q: Can I purchase an iScan VP50 with the SDI input module installed.
A: At this point, this card is purely a user/dealer-installable upgrades. Both are very easy to do and the installation of either will not void your warranty.
Q: Does the iScan VP50 use the same SDI input module as the iScan HD, HD+, VP20 and VP30?
A: Yes, the iScan VP50 uses exactly the same input module.
Q: Can the iScan VP50 take an HDMI input signal and output that same signal over the analog outputs?
A: If the input signal has HDCP (High-bandwidth Digital Content Protection) legally we must turn off the analog outputs. If the input signal does not have HDCP, then the iScan VP50 CAN output this signal as an analog signal (either RGB or component) at any resolution between VGA and 1080p.
Q: What features does the VP50 have, which the iScan VP20/VP30 do not have?
A: • Precision Video Deinterlacing™ by ABT for SD (480i/576i) and HD (1080i)
VP20/VP30 use the SiI504 for SD deinterlacing and both are upgradeable to the ABT102 (Precision Deinterlacing Card).
•HDMI Inputs can process up to 1080p
VP20/VP30 can process up to 720p/1080i
There will be more features/differentiators added to this list
Q: If I connect an HDMI (audio/video) source to the iScan VP50 will I be able to get audio out via the optical/coaxial digital outputs?
A: In most cases the audio that is available on the HDMI connection will be available on the optical/coaxial audio outputs. Exceptions include MLP (DVD-Audio) and DSD (SACD) which SPDIF connections are incapable of carrying due to bandwidth limitations.
Je vous traduis tout ça au plus vite
Déjà, les différences avec le VP30 actuellement disponible :

Le VP50 dispose de l'algorithme de désentrelacement de ABT (appelé Precision Video Deinterlacing et actuellement l'un des meilleurs pour la SD et disponible pour le VP20/VP30 en carte d'extension pour la SD seulement) pour la SD ET pour la HD (1080i).
Les entrées HDMI sont en mesure d'accepter un signal 1080p (idéal si on dispose d'un lecteur HD DVD ou BluRay en mesure de sortir directement le flux 1080p)
D'autres fonctionnalités et différentes viendront s'ajouter à cette liste dont :
- en premier lieu le réglage du gamma absent des VP30/VP20 :
Josh a écrit:ABT’s Precision Gamma Correction™ - Individual R/G/B Adjustments
- la mise à jour des algorithmes de traitement au travers de mises à jour logicielles :
site DVDO a écrit:Ability to update all processing algoriths through software updates
- la détection de cadences HD 24p et 25p (cf ci-dessous) :
site DVDO a écrit:Progressive Source Input Cadence Detection (Source-Locked Output without Deinterlacing)
Une autre différence par rapport au VP30/VP20. Il peut prendre un signal audio en provenance d'une entrée HDMI pour l'envoyer en coax ou optique. Le VP30/VP20 ne pouvait le faire QUE si le signal en entrée n'est pas HDCP (autant dire que c'est impossible car c'est généralement le cas).
Et le lien vers la page du DVDO VP50.
Que demander de plus
UPDATE :
en entrée HDMI, il ne sait prendre que du 1080i à 50/60hz ou du 1080p à 50/60hz. Par contre, voila ce qui est indiqué dans le manuel disponible sur le site DVDO :
manuel a écrit:
For 50Hz sources, if the original source material is progressive at 25Hz (uses 2:2 pulldown), the output
framerate can be source locked at 25Hz, 50Hz or 75Hz. The 25Hz setting outputs each original
25Hz frame, the 50Hz setting repeats each original 25Hz frame 2 times, and the 75Hz setting repeats
each of the original 25Hz frames 3 times. You can also set the output frame rate to a specific value
(unlocked mode).
For 60Hz sources, if the original source material is progressive at 24Hz (uses 3:2 pulldown), the output
frame can be source locked to 24Hz, 48Hz, 60Hz or 72Hz. The 24Hz setting outputs each original
24Hz frame, the 48Hz setting repeats each original 24Hz frame 2 times, while the 72Hz setting repeats
each frame 3 times. As with 50Hz sources, you can also set the output frame rate to a specific
value (unlocked mode).
Donc avec les HDDVD et les BluRay, il faudra sortir en 60hz entrelacé vers le VP50 (si comme "prévu" ils sont tous encodés en 24p) qui pourra ensuite retrouver le flux original 24p, voir le sortir en doublant ou triplant exactement chaque frame pour faire du 48hz ou du 72hz.
