Solo per completezza indico alcune delle caratteristiche del DVDO HD
che mi paiono in gran parte non disponibili sul Cinemateq:
1) Lipsync correction.
The iScan HD has 4 digital audio inputs, 2 optical and 2 coax, each of which can be assigned to any of the video inputs (more on those in a bit). I.e., when you switch to video input A, then the audio input which has been user-assigned to video input A will also be selected.
The audio channel provides a delay which matches the video processing delay of the iScan. Note that this delay will vary depending on the current configuration and processing mode of the iScan. For example, if an input signal is just being passed through with no video processing, then there will be no delay added. 50 Hz sources will require a different amount of delay than 60 Hz sources, and frame rate conversion requires more delay than no frame rate conversion. The correct audio delay for all these cases is set automatically, so the user need do nothing extra to match audio and video delays. In addition, there is a user-adjustable additional delay (up to 255 mS) which can be added (or subtracted) on top of the automatically set delay.
Note that only digital inputs are provided. If analog inputs are needed, then a separate 3rd-party A/D is required.
2) Inputs.
There are 2 composite video, 2 S-Video (Y/C), 2 component, one analog passthrough, and one DVI input. (There will also be an optional SDI input card. This is currently under development, however, so there is probably more risk associated with this feature than with the others I'm discussing here.) There is one analog output and one DVI output. The DVI input can function as an input or as a passthrough; HDCP passthrough is supported but an HDCP-protected signal cannot be scaled. The iScan automatically detects whether it can process the incoming DVI signal, and changes to passthrough mode when it can't.
The component inputs are a bit unique, so let me describe those. They accept YCbCr or RGBs formats. 480i and 576i signals are deinterlaced and scaled, 480p and 576p inputs can be scaled, while higher resolutions formats automatically routed through the iScan without any processing (i.e., a passthrough mode). This means that a video source device which can output SD interlaced, SD progressive and/or HD can be attached to just one component input and the iScan will 'do the right thing'.
3) Deinterlacing and scaling.
The deinterlacer is still an SiI504, although we have been able to make it do a few tricks that others have not (e.g., see #4 below). The scaling engine is a custom design of our own which introduces minimal phase and amplitude errors and provides better performance than we've seen in competing products. (There is another thread in this forum which has some screenshots of this.) The scaler can scale up or down, so it can handle all types of aspect ratio conversions, unlike some competing products.
4) Frame rate conversion.
There are 3 basic operating modes:
A) Source-lock mode where the output frame rate exactly matches the input frame rate.
B) Arbitrary output frame rate which is not locked to the input.
C) Progressive source-lock mode with frame rate conversion to an even multiple of the source frame rate. 24 Hz film-source material using a 3:2 pulldown pattern can be output with 2:2 pulldown at 48 Hz or 3:3 pulldown at 72 Hz. 25 Hz film-source material using a 2:2 pattern can be output using 3:3 pulldown at 75 Hz. These output rates are fully locked to the original 24 or 25 Hz source rate and are not actually 'floating' as with a several other scaler products which offer 72 or 48 Hz output frame rates without really locking to the original film source rate.
5) Price.
The final price has not yet been settled on. Expect something in the $1300 to $1900 range, most likely somewhere about the middle of that range.

Francamente mi pare che il prezzo sia anche inferiore, considerando l'attuale cambio del dollaro, ipotizzando infatti 1500 $ per la versione base e diciamo sui 300 $ per l'opzione SDI, si arriva a 1.800$, che corrispondono a 1.400€, con IVA 1.700 €. Anche con spese di spedizione pazzesche non si arriva al prezzo del Cinemateq SDI...
Le caratteristiche di cui sopra sono molto valide, sulla carta anche superiori - anche da solo il lip-sync delay vale parecchio...
Inoltre il DVDO è aggiornabile via RS232.
Penso che aspetterò ancora per vedere le prime recensioni su AVS.
Grazie Peval, ho editato...
...riguardo all'acquisto, mica è vietato farlo oltre oceano.
L'ISCAN Ultra si trova in USA via web a meno di 800 Euro già sdoganato, più spese trasporto: fai una ricerca con Google e troverai parecchi siti che lo vendono a un prezzo simile!!
Il prezzo ITA puoi vederlo da te :rolleyes:
Fatte le debite proporzioni, e considerando che il prezzo da me segnalato è quello proposto da DVDO, quindi probabilmente soggetto a sconti promozionali, ci sta tutto l'acquisto tramite web.
IMHO, ovviamente.

Credo proprio che poichè il prezzo ITA è molto più alto, stavolta ci scapperà il corriere internazionale.
Beh se poi fate un co-buy risparmiate parecchio sulle spese di spedizione!;)
Se qualcuno poi mi vuole dare la sua Holo...:D
