The combination of two devices in one basically allows to lower cost, to reduce borrowed space and to simplify (to exclude) switching blocks. Combine Optoma DV MovieTime combines large-format DLP-proektor, DVD-pleer and acoustic system. All process of installation is simplified by that up to a limit: has hung up the screen, has put a projector and everything, it is possible to look cinema. We already tested a similar combine from Epson, but Optoma notebook discounted DV differs special compactness and in small weight that gives to it the raised mobility.
Adapter with SCART on mini D-sub pin and S-Video
Presence of a bag emphasizes an accessory of the device to a class a mobile house cinema. Walls of a bag on perimeter rigid, greater lateral walls soft. From the interior of a leaning back cover there are pockets for small things and cables, one notebook discounted more karman-setochka is fixed on lipuchke in the main branch. On a bag it is applied kapron naplechny'y a belt.

Externally the projector looks very unusually: it reminds something a turtle, with asymmetrically located head notebook discounted an objective. Something, but not raskraskoy. It aggressively black-and-white.
The case of a projector is made of plastic with a matte covering, lattices dinamikov metal. DVD-privod is in the center of a back and it is arranged also, as at the majority of portable players: podprujinennaya the cover on a latch opens access to a spindle, on which nasajivaetsya a disk.
Spaces in a compartment of a drive suffice for problemless extraction of a disk by not notebook discounted tiny fingers. On both parties from a drive in black surrounding obodke are located buttons of management. Their functional differentiation is underlined by a spatial arrangement: at the left the buttons operating DVD-privodom and the red indicator, burning when in a drive there is a disk,
The button of a feed (in its center the dark blue indicator, it blinks in an on duty mode and it is shone in the worker) though it is located on the right, but, clear business, vy'klyuchaet-vy'klyuchaet and proektornuyu a part, and DVD-privod simultaneously. notebook discounted Two small dynamics look back and in the parties (in the parties for virtual expansion of stereobase). The bent lateral surfaces are borrowed by ventilating lattices. All sockets, including for lock Kensingtona, are on the back panel.
IK-priemnikov two in front and behind. The lobby a leg put forward from the case allows to raise a little a projector, and two back, getting out the case, will help to eliminate a skew.
Special apertures for fastening a projector to potolochnomu to an arm, for the clear reasons are not present. In fact it should to rise notebook discounted each time on a stool to insert a disk into this projector located under a ceiling.
The board enough big, in a hand lays conveniently. In the central group there are buttons, basically managing directors DVD-pleerom. It is four-item knopka-kol'co and the button in the center of this ring, intended for moving on the menu of a disk and the menu of installations DVD-pleera, two knopki-kachalki change notebook discounted of loudness and correction of a trapeze (and it is not a pity buttons of the board on function to which, most likely, should not take advantage and if and it it is necessary only once for a session), and more useful buttons. To buttons of the central group of claims is not present to use them conveniently, to the touch are. But here the important buttons which are responsible for rewind, transition, reproduction, a stop and a pause are born far back where to not reach, they fine and in notebook discounted them it is easy to get confused. With buttons in a forward part of the board, concerning to proektorny'm to the functions, in general a full failure. Kursorny'e buttons for navigation under the menu of a projector are located not by a habitual cross, and in a number, the others buttons very narrow, located closely and on the edge of the board. In general to adjust a projector it is more convenient by means of buttons on the case, instead of on the board. Really it was impossible to notebook discounted adapt for moving under the menu of a projector of the button of the central group? As a last resort, could make the mechanical switch of functions of buttons of the board: projector DVD-pleer. Neither light-emitting diode illumination, nor a phosphorescence facilitating work with the board in darkness, no.
Screen menus two: the menu with installations of a player and the menu with adjustments of a projector. They absolutely different on style and a principle of the notebook discounted organization. In the menu of a player it is used large, horoshochitaemy'y a font. The menu of a projector though borrows a lot of place on the screen, but contains the inscriptions executed by very fine font. Almost all adjustments both the menu are on pages of the first level, to scroll pages it is not necessary, and to get more deeply the first level it is necessary infrequently. At adjustment of the notebook discounted parameters influencing the image, the menu of a projector disappears from the screen, there is only a scale with current adjustment, and the menu of a player keeps the position on the screen, complicating an estimation of occuring changes. For the menu of a projector it is possible to choose Russian (quite good translation), I for the menu of a player was not present.
Interfaces USB and RS-232C, most likely, are used exclusively in the service purposes. At least, notebook discounted we could not learn, how they can be used and where to take a corresponding software. The projector can be connected to video equipment with socket SCART at which are present RGB-or S-Video-signaly'. For this purpose the adapter going the complete set with SCART on VGA and S-Video is required.
To connect a projector to a source componental cvetoraznostnogo a signal it is necessary to get or make kabel'-perehodnik with RCA on VGA-raz`em. In a complete set of the projectors which are on sale in the USA, the notebook discounted demanded adapter with RCA on VGA-raz`em enters, but Russia is ranked as the Europe that is why the Russian users, wishing to use componental connection, it is necessary to go on additional charges. You do not cease to be surprised economy of manufacturers on cheap accessories.
That at connection of external sources of video signal to force to work dynamics of a projector, it is necessary to take advantage of two sockets RCA from group AUDIO IN. And on notebook discounted the contrary, the external sound system is connected on the analog stereointerface (a socket minidjek) or on optical digital (sockets in group AUDIO OUT). As a source of the image and a sound in this case serves built in DVD-pleer. Digital connection is a unique way to receive a multichannel sound from this source and-or to hear DTS-dorojku.
All possible sources of the image and a sound on a cycle get over button Source on notebook discounted the board or on the case. Operating mode VGA-vhoda is established in the menu. There is an autosearch of active connection (it can be disconnected), thus for active connection to the built in player even if in it there is no disk always is accepted. Simple change of type of a signal (for example, from PAL in NTSC) includes autosearch, therefore a projector can show transition amateur performance and is switched on other source, is usual on itself.
For focusing the notebook discounted image it is necessary to rotate funneled blendu an objective, and change of a focal length (the size of the image) is carried out ry'chajkom to the left of an objective. The range zummirovaniya absolutely small and at change of a focal length focusing gets off, that is inconvenient. The objective is fixed concerning a matrix so, that the bottom edge of the image is strongly above an axis of an objective (approximately on half of height of the image) so notebook discounted the projector costing, for example, on a low coffee table, most likely, should not be raised. But just in case digital correction vertical trapeceidal'ny'h distortions (+/- degrees) is stipulated, though at a matrix of such small sanction this correction leads to appreciable distortions of the image, and it is better to not use to it.
Modes of transformation 4: 4x3, 16x9, LBX and 16x 1:1.
The first it is the usual modes meeting in any large-format projector and optimized for viewing of films of notebook discounted a format 4:3, anamorfirovanny'h and LetterBox, accordingly. The special mode 16x 1: is intended for viewing anamorfirovanny'h PAL-fil'mov the image stretched up to a parity 16: and the part of a picture obrezaetsya is deduced 1: on a vertical with the sanction of a matrix, i.e. with the minimal distortions, but. In addition there is an increase (Zoom) with small step from 1,1x up to 1,4x. If necessary to place on the screen subtitles the image it is possible to shift vverh-vniz (Image Shift). If on edges notebook discounted of the image there is a noise it can be deduced from a zone of a projection, having taken advantage of adjustment Overscan.
The projector is enough korotkofokusny'y that at face-to-face displaying it could be put before spectators. The arrangement built in dinamikov just assumes such type of accommodation.
To correct yarkostny'y balance and to correct colors it is possible by means of of some adjustments: brightness, contrast, a saturation, a shade, planimetric sharpness, correction gamma-krivoy (Degamma) and color temperature (abstract values 0, and 2). Also by means of notebook discounted 6-ti toddlers on page True Vivid brightness and contrast of three primary colours is adjusted.
The raised brightness of a lamp joins translation of parameter Bright Mode in condition On.
At desire it is possible to trust in automatics of a projector, having included mode Image AI. In this mode the projector itself adjusts brightness of a lamp, brightness and contrast, and also changes gamma-korrekciyu, depending on yarkostnogo balance of an initial picture. The preestablished values of adjustments are in 5-ti structures, and the user set is remembered in structure User separately for notebook discounted each type of connection.
Separate discussion is deserved with parameter White Peaking. It operates inclusion of a transparent segment 7-misegmentnogo an optical filter. If White Peaking it is equal this segment is switched off and if that it is completely included in process of formation of the image. Inclusion of a transparent segment is raised with brightness of white sites, but relative brightness color thus decreases, the image to become dim. For an illustration we shall result two pictures from the screen. The first transparent segment is switched off, the second is notebook discounted included. An exposition in both cases identical.
It is visible, as brightness of a white strip, but colors dim in both photos has increased. Now we shall correct an exposition of the first picture on a white strip, simulating work of sight of the person, and we shall receive the third picture, where colors bright and sated.
Thus to correct the second picture already there is no place, as the exposition there is initially exposed on a white strip. In general, use of a transparent segment is justified in notebook discounted presentation projectors where great value has brightness of a white field, and a colour rendition not so is important. In film-theatrical projectors the transparent segment is absent, as for its correct colour rendition all the same it would be necessary to disconnect, i.e. the parts of the world from a lamp in vain would leave in an absorber, instead of on the screen. The given projector with the 7-misegmentny'm an optical filter notebook discounted borrows intermediate position and as it would seem to us, quite could manage and a transparent segment.
Measurement of a light stream, contrast and uniformity of illumination were spent by a technique
- In a mode of high capacity, White Peaking = 0
- In a mode of high capacity, White Peaking = 10
- In a mode of low power, White Peaking = 0
- In a mode of high capacity, White Peaking = 0
- In a mode of high capacity, White Peaking = 10
The maximal light stream even at the included transparent notebook discounted segment less passport 10 lm, however, to carp there is nothing, as is not told anywhere, that in the passport the value received by technique ANSI is resulted. Uniformity of illumination of the screen average. Contrast very high.
And they cannot be compared to nameplate data of a projector directly.
Basically, the special discomfort at viewing films does not arise even then when the projector is in a mode of the raised brightness, but cinema with a silent soundtrack, without explosions, etc., it is better to look in a silent notebook discounted mode, having offered brightness of the image.
854x4 our videocard does not support the sanction, therefore testing was spent at the sanction 8 on 4 pixels. White and black fields uniform, and color divorces are not present patches of light. Geometry correct. Details differ both in shadows, and in svetah. A scale grey in regular intervals grey. Colors at White Peaking = bright and correct. Clearness very high. The width color kaymy', arising because of chromatic aberrations of an objective, does not exceed 1/ notebook discounted pixels.
Is better a projector shows, when a source of the image is built in DVD-pleer, yarkostnaya and color clearnesses very high. In any case test tables with gradients of colors and with a scale grey generating correctly. Weak gradation of shades in shadows and on light sites of the image well differ. The color balance correct, on the motionless worlds is not present artefacts.
Function of progressive transformation is optimized for restoration of the staff cheresstrochnogo PAL-and NTSC-video, received of an initial material with frequency kadra/s, and correctly enough notebook discounted makes transformation 2- and 3-2. However, the algorithm nonrigid, and in doubtful cases the image is deduced on fields to avoid artefacts in the form of a hairbrush on edges of objects. The fuctioning of function deinterleysinga shows, that from the built in player goes cheresstrochny'y a signal, and for progressive transformation the videopath of the projector answers. Smoothing of borders is not carried out, therefore on diagonals of moving objects it is possible to notice a step.
Testing has shown, that alternation of colors notebook discounted at PAL-signale occurs to frequency of 2 Hz it corresponds 4-h-skorostnomu to an optical filter. Speed is enough greater effect of a rainbow certainly is present, but is swept not so up. And traditional disklamaciya sensitivity effect of a rainbow is defined by specific features.
Playing MP (8-3 kbit/s and VBR, 8- kGc) + *
Built in DVD-pleer it is the usual player of an initial level probably based on the chip, not supporting decoding MPEG4. All standard functions on playing notebook discounted DVD-Video are present, deserving special attention is not present anything. At reproduction DVD-Video, CD-DA, multimedia files, etc. button Display displays an information line,
And button GoTo navigating by means of which it is possible to choose section or a track, the chapter or to enter taym-kod positions of playing.
Contents of disks with multimedia files represent a player in the form of two lists: in left all folders, in right files in a current folder.
The player displays only types of files supported at present and folders which contain them. The type of files is switched by buttons below notebook discounted audiofiles, JPG-fayly' or videofiles. In the left part of the screen the reduced image current JPG-kartinki is shown.
From long names first symbols get into lists only. All is deduced by capital letters, and instead of cyrillics and some symbols the player shows a symbol of underlining. Files and folders are numbered, quickly to choose necessary (necessary) it is possible by means of digital buttons of the board.
At playing MP3-faylov tegi are not displayed, the pause between MP3-faylami small approximately 0, with, the beginning of a notebook discounted track is muffled a little, there is fast rewind MP3-faylov and transition to necessary time, it is possible to move independently on a disk, and the player itself passes in a following folder.
Viewing JPG-faylov can be organized in the form of slayd-shou. The index mode is not present. The player can show greater on size JPG-fayly' (at least, up to 39 on 26 pixels), but does it slowly, but already loaded picture rotates and reflects quickly.
The menu of installations DVD-pleera is not adapted absolutely not for work in structure of a combine. To what to leave a choice of notebook discounted system of video signal and a format of the screen if a projector multisystem and with the screen 16:9, and the video output is not present?
The expediency of a page with adjustments of the image too raises the doubts, as superfluous adjustments (brightness,) only confuse contrast, a saturation and a choice of a structure.
For convenience of the user, perhaps, it would be necessary to pick up an optimum combination of adjustments and to block access to this page.
Dynamics loud enough, but quality of a sound low. Strongly pronounced plastic sounding is notebook discounted not present, however is not present both high, and low frequencies, and on average and big loudness presence of nonlinear distortions is felt. Basically, it is possible to connect an external subwoofer, either an active stereosystem, or a receiver on the optical interface. However it is necessary to notice, that loudness built in dinamikov, the level on an analog audiooutput and even on digital (!) varies synchronously, and to disconnect built in dynamics it is impossible.
Non-uniformity ACHH (from Hz up to kGc), dB:
Non-uniformity ACHH (from notebook discounted Hz up to kGc), dB:
Operating mode: MP 3 kbit/s, bats, kGc
Non-uniformity ACHH (from Hz up to kGc), dB:
Operating mode: MP 3 kbit/s, bats, kGc
Non-uniformity ACHH (from Hz up to kGc), dB:
On the digital interface a signal at reproduction of disks CD-DA ( bats, kGc) are transferred c by the minimal distortions. Also record on interface S/PDIF has shown, that the player perfectly copes with decoding MP3-faylov. During too time quality of an analog audiooutput low, such impression, that the notebook discounted audiopath is brought into accord with built in dinamikam or on the contrary.
It is not enough adjustments of a sound. In the menu it is possible to choose an operating mode of a digital output, to adjust mix in a stereo, to adjust a dynamic compression and zachem-to correction of tone.
Optoma DV MovieTime the interesting device, undoubtedly deserving the award for original design.
The combine has turned out self-sufficient and as a whole balanced enough, though developers should think how to notebook discounted improve symbiosis of components and by that to facilitate a life to the user.
