Μια γρηγορη μεταφραση εδω

"Got some information about the new JVC projectors! X30, X70 and X90 ... New CMS, which provides better opportunities for calibration, a little more contrast, still 120Hz 3D (cf. 240Hz with Sony and 480Hz with Epson!), on 70/90 models they could also offer "4k" by pixel jumping, that is not native, but through some kind of wobbulering or similar, that is still 1920x1080 chip - but perhaps most interesting: Lens Memory by switching between 2.35:1 and 16:9 - this seems to be little of a trnd now :) mvh / Pär "

Για να δούμε τι βελτιώσεις θα φέρει η νέα γενια...

Καταρχήν το επίσημο δελτίο τυπου:


New JVC Home Theater Projectors Display Images With 4K Precision

Four new models upconvert images to four times the resolution of Full HD.

INDIANAPOLIS, September 8, 2011 - (Virtual Press Office) - JVC today introduced new home theater projectors that display 2D HD content with full 4K precision. They feature JVC’s new e-Shift technology capable of projecting images with 3840 x 2160 pixel resolution, four times that of full HD. The upconverting technology is available in four of seven new 3D-enabled projectors that boast a wide range of advancements, including higher native contrast than previous models for levels that remain unmatched by any other home theater projector.

The new projectors are the Procision Series DLA-X90R, DLA-X70R and DLA-X30, marketed by JVC’s Consumer Electronics Group, and the Reference Series DLA-RS65, DLA-RS55, DLA-RS4800 and DLA-RS45, available through JVC Professional Products Company. JVC’s 4K e-Shift technology is featured in the top four models, while all seven new projectors offer other advancements that boost picture quality, improve 3D performance and enhance functionality.

Earlier this year NHK Science & Technology Research Laboratories, NHK Engineering Service Inc. and JVC Kenwood Corporation collaborated in the development of a Super High Vision projection system that utilizes e-Shift technology. Now, that technology is available in the DLA-X90R, DLA-X70R, DLA-RS65 and DLA-RS55. Using e-Shift, 2D HD content is upconverted and scaled to a 4K signal (3840 x 2160) and the e-Shift technology displays it at full 4K precision. Compared to a Full HD (1920 x 1080) image, that’s twice the horizontal and vertical resolution and four times the number of pixels, or over 8 megapixels. The result is a stunningly detailed image with minimal aliasing artifacts found in standard HD displays.

All seven projectors are 3D-enabled and offer several 3D performance and feature enhancements:

• 2D-to-3D Converter – Converts 2D program material to 3D using technology derived from JVC’s professional 2D-to-3D converter. Included are user adjustments for 3D depth and subtitle geometry correction;
• JVC’s 3D anamorphic feature combined with an optional anamorphic lens make it possible to enjoy 3D movies in the popular 2:35 scope format;
• Compatibility with a wider range of 3D broadcasts, including 1080p/24 and 720p side-by-side formats;
• Brighter 3D images than previous models are possible through the use of an improved driver that keeps the shutter on the active shutter 3D glasses open longer, thus allowing more light to enter, while at the same time minimizing cross talk;
• A Cross Talk Canceller further reduces cross talk through analysis of the left eye and right eye signals and applying appropriate correction;
• A parallax adjustment allows the user to tailor the 3D image effect;
• Direct access to 3D formats and settings on the remote control.

In addition, the top four models -- DLA-X90R, DLA-X70R, DLA-RS65 and DLA-RS55 – have been designed to achieve THX® 3D certification and are scheduled for testing by THX. During the THX 3D certification process, more than 400 laboratory tests are conducted, evaluating color accuracy, cross-talk, viewing angles and video processing to ensure the superior out-of-the-box 3D and 2D display performance that home theater enthusiasts demand.

Other features shared by these four models include:

• ISF certification;
• Enhanced installation adjustment, including a new 1/16th pixel shift function to precisely tune convergence via 121 adjustment points (11 vertical x 11 horizontal) and an increased number of screen mode preset positions, up to a maximum of 255;
• An upgraded optical engine that further improves black level and native contrast;
• 7-Axis Color Management System;
• ISF and THX Calibration via corresponding software to allow advanced adjustment by certified ISF calibrators;
• Three Xenon lamp color modes that emulate the characteristics of high-end movie projectors.

Other enhancements new for all seven 2012 projectors are:

• Lens memory function – Three memory settings store custom focus, zoom and horizontal/vertical lens shift position. This allows a constant height display of 4:3, 16:9 and 2:35 scope content without an additional anamorphic lens;
• A LAN connection that provides enhanced system control and easy firmware or screen mode updates.

To provide enthusiasts with a true measure of performance, JVC has long focused on native contrast and refused to artificially enhance contrast specifications through the use of a dynamic iris. For 2012, native contrast has been improved across the entire line, ensuring that every frame consistently and faithfully reproduces peak whites and deep blacks.

The new flagship projectors, the DLA-X90R and DLA-RS65, are built using hand-selected, hand-tested components and provide a 120,000:1 native contrast ratio. For 3D viewing, both models come with two pairs of 3D glasses and a PK-EM1 3D Signal Emitter. Both projectors also have a three-year warranty.

The DLA-X70R and DLA-RS55 offer 80,000:1 native contrast ratio, while the DLA-X30 and DLA-RS45 offer 50,000:1 native contrast ratio. All four projectors come with a two-year warranty. The DLA-RS4800 is ISF certified, offers a 55,000:1 native contrast ratio, comes with a three-year warranty, and includes a spare lamp. JVC Active Shutter 3D Glasses and the PK-EM1 3D Signal Emitter are sold separately.

All seven new projectors feature three 0.7” 1920 x 1080 D-ILA devices and are designed around JVC’s third generation D-ILA High Dynamic Range optical engine that is optimized to provide exceptional native contrast ratios without a dynamic iris to artificially enhance contrast specifications. A directed light integration system and wire grid polarizer ensures optimum light uniformity and minimal crosstalk in the light path. In the top four models (DLA-X90R, DLA-X70R, DLA-RS65 and DLA-RS55) a combined 16-step lens and lamp aperture adjustment allow the user to optimize the f-number (relative aperture) of the optics system in all steps. The DLA-X30, DLA-RS45 and DLA-RS4800 feature a 16-step lens aperture.

The new JVC D-ILA home theater projectors will be available in November at the following prices:

DLA-X90R/DLA-RS65 $11,999
DLA-X70R/DLA-RS55 $7,999
DLA-RS4800 $4,995
DLA-X30/DLA-RS45 $3,499

In addition to the JVC PK-AG1 active shutter 3D glasses currently available, JVC announced new glasses – the PK-AG2, which are more compact, lighter and rechargeable. The PK-AG1 glasses remain available and are ideal for use over eyeglasses. Both models are compatible with the currently available PK-EM1 3D Signal Emitter.

Τα κλασικά ''ενδιάμεσα / marketing'' ''νέα'' μοντέλα χωρίς ουσιαστικες αλλαγές.

Η μόνη πρακτική διαφορά (κι αυτή βέβαια όχι όσον αφορά την ποιότητα εικόνας) : Lens memory function

Αυτό σημαίνει, ότι αν η ταινία είναι 2.35:1 θα επιλέγουμε την μνήμη: θα την "ξεχειλώνει" κατακόρυφα για να πιάσει όλο το πάνελ και μετά την καδράρει σε 2.35:1
Αν ναι, περιττό να σας πω τι φωτεινότητα και τι καθαρότητα επιπλέον κερδίζεται.
Μην ξεχνάτε ότι μια ζωή "πετάμε" πάνελ (aka black bars).

Τα περί constrast ειναι οι κλασικές μούφες του τύπου ''νεο μοντέλο, ας του δηλώσουμε +Χ σε CR''.

Για τα γυαλιά κλπ, κάτι για αλγόριθμους λένε οπότε περιμένω να δω αλλά δεν νομίζω....

Για την μνήμη Τάσο, δεν κατάλαβα τι λες (ο προβολέας πως μπορεί να προσωμειάσει τη χρήση αναμορφικού φακού; τι πάει να πει ''μετά την καδράρει σε 2.35:1''; πως μπορει να το κανει αυτό χωρίς αναμορφικό και με τη χρήση ολου του πανελ; - τι δεν κατάλαβα; ) .

Απλως μια (πολλές) μνήμη θα ναι για θεση zoom κλπ.

Ρε Τασο, αν είναι αυτό, το κανεις και με τον lumagen!

ΟΧΙ, διότι πάλι πετάς πάνελ.

Για να κερδίσεις το πεταμένο πάνελ , πρέπει να κουνηθεί το ζουμ και να ξαναγίνει netting. Αυτό με την χρήση της μνήμης θα γίνεται εύκολα.

Αυτό όταν έχετε οθόνες με κάδρο 2.35:1.

Ρε σεις, το έγραψε ο Τασος: Αλλάζει αυτόματα το zoom και το focus της εικόνας ώστε το κάδρο να γινει 2.35.1 και να ταιριάζει με τις 2.35.1 οθόνες. Κοινώς, αντί να το κάνει κάποιος χειροκίνητα κάθε φορα, γίνεται με το πατημα ενός κουμπιού. Βεβαια αν δεν έχεις 2.35 ή multiformat οθόνη δεν έχει νόημα.

Re: Απάντηση: JVC DLA X30/X70/X90

Ναι ρε παιδι, αυτο ειναι το προφανες, αυτο λεω τόση ώρα.

Τι σχέση όμως έχουν αυτά που γράφει ο τάσος:

''θα την "ξεχειλώνει" κατακόρυφα για να πιάσει όλο το πάνελ και μετά την καδράρει σε 2.35:1
Αν ναι, περιττό να σας πω τι φωτεινότητα και τι καθαρότητα επιπλέον κερδίζεται''

Αυτά που λέει ο Τάσος (ξεχείλωμα, κέρδος φωτεινότητα κλπ) εχουν να κάνουν με τη χρήση αναμορφικού και όχι με την μνημη του lens shift κλπ, σωστά;

Στο cine4home το εξηγεί σε άπταιστα γκουγκλια αγγλικά :p


Cinema Scope
By far the majority of films are not in the traditional 16:9 aspect ratio filmed, but the extra wide screen format of 21:9 (2.35:1), and "Cinemascope" called. The advantage of this format is even better utilization of the human visual field, so that may be generated from very small distances is drawn even closer to reality and thus of moviegoers still more under the spell of the game film.

If the cinemascope format the movies now so much closer than the "compromise" format 16:9, why not use a true home cinema fan and a matching "widescreen"? In fact, more and more home theater enthusiasts know the benefits of "real" screen size, but usually is complicated by the installation of several hurdles:

The main problem lies in the different aspect ratios: one projects a Cinemascope film full frame 21:9 on a corresponding screen, so you have the optimum utilization. But we want to project the next step is a conventional 4:3 or 16:9 image, so you must zoom the image smaller so that the image height again fits into the cinemascope screen. With each change of format according to a new adjustment of the zoom, focus and lens shift is necessary even with the motor, this luxury is disturbing in the long run. For this reason many home theater installations, falls into the traditional choice on a 16:9 screen. With it uses, not from the full potential size of Cinemascope films (top and bottom black bars), but after all, must also be adjusted for different image formats, the projector is not new, visually.


Cinemascope movie on 16:9 screen:
The unused areas of the screen are illuminated by the projector also
and appear especially in dark scenes disturbing gray.

If one already has a motorized zoom & focus, why not save a variety of settings, so that they can be retrieved on demand by remote control and the projector is adjusted automatically to all the relevant preset? This is precisely what the new JVC projectors:

The first step is to set the zoom & focus of a 16:9 image by remote control so that the image height of the Cinemascope screen is maxed out. The unused portions of the screen remain unlit and are therefore completely black and do not like dark picture scenes at a 16:9 screen.


16:9 material on-screen Cinemascope
Although the side areas of the canvas is not used, but they do not appear gray,
because the projector is not shining on the fields.


If the image is adjusted optimally, we save this setting in one of the three available memory slots from. The next step is feeding the projector now formatfüllendem cinemascope material and adjusts the zoom and focus again on the screen perfectly. In other words, it zooms the picture on the extent (and regulates the field) until the image height and width exactly fills the screen.


High-quality Cinemascope screens (eg Davision)
provide maximum film format in full size

All settings are then always accessible by pressing a button and the projector automatically adjusts to the desired image format.

Τί να μας εξηγησει;

Πως κανουμε zoom κλπ οταν αλλαζει το format;

Και οτι απλως πλεον εχουμε μνημες γι αυτο;

Ξαναλέω:

Όλα αυτά ειναι βολικά αλλά δεν οδηγούν σε καμία αύξηση φωτεινότητας, μη πεταμα panel κλπ που λέει ο Τάσος.

Αυτα προυποθέτουν χρήση αναμορφικού φακού.
