Nut G1S Mobile Cinema Strikes Let the Cinema Go!

Overview and introduction of official parameters

The so-called melons and melons are all necessary. If you want to bring in golden phoenix, you must have a phoenix tree. As a company, in order to gain a firm foothold in the industry, in addition to having a good team, excellent products are also essential. In the era of the Internet + new product, although the overall situation of the micro-investment industry is still developing steadily, the war without smoke has started among enterprises. As a "rising star" in the micro-investment industry, Hollotech has broken through "heavy barriers" by virtue of its scientific management concept, outstanding marketing methods, unique living characteristics, and individualized products, and has become a benchmark for many companies in the industry.


When the nuts G1 and P1 smart mobile theater products were sold for sale, Huoleng Technology once again built a G1 upgrade product G1S. In addition to maintaining the same appearance as G1, the Nut G1S smart mobile cinema has significant improvements in many major performance aspects. The following figure shows the technical parameters given by the official G1S nuts. We can see that G1S is comparable to G1. Words have a significant increase in brightness, and there are also subversive changes in handling.


On the packaging side, the Nut G1S uses a well-placed quadrilateral type of reverse packaging. All new machines have a one-time sealing glue seal at the packing opening, and the packaging format is similar to that of the SLR camera. The box is mainly based on white, with golden LOGO logo and black font, simple but not simple.


After opening the box, you can see that the inside of the box is made of stamping-type pearl cotton as a buffer layer, and the thick buffered pearl cotton can effectively ensure that the machine will not be injured during transportation. After removing the top layer of protective pearl cotton, the local gold G1S is in sight.


In terms of accessories, the Nuts G1S mobile cinema is equipped with a variety of random accessories such as a power adapter, a product booklet, a warranty card, a fixed tray for bracket mounting, and even a battery for the remote controller. Full shot Bluetooth remote control. In terms of accessories, the power adapter is very similar to the power adapter of the earlier laptops, and it is too large. At the same time, the G1S smart microprojector has not delivered 3D glasses. It is a little disappointment for the Wolf friend who loves to show 3D videos.


This is what, microphone? Gamepad? remote control? NO~~~~~, this is a new type of “conductor” that incorporates a variety of practical functions such as voice control, operation, focusing, etc., which are randomly worn by the Nuts G1S smart micro-projection. With one stick in hand, all functions of the G1S can pass. It comes to fruition.



From the appearance of the machine alone, the G1S smart micro-projection of the nuts has not changed compared with the previous generation product G1, except that the popular atmosphere and the golden local tyrants symbolize local color as the main colors. The shape of the machine adopts a pure circular design, and no buttons are designed on the machine except for the “hidden” button of the switch machine in the middle position.


Nuts G1S Smart Mobile Theater The top of the fuselage is made of pure metal, similar to the antique mirror local gold design, personally feel that if you design the panel with a metal brushed effect will be more ideal. The bottom adopts the black model of one-piece punching-opening PVC plastic material. At the same time, there is a large-diameter cooling fan at the bottom. The fan uses a high-density metal dust-proof net design to effectively prevent large particles from entering the machine.



The nut G1S uses a 1.2:1 high-transparency coating lens for projection ratios to project larger-size projection images over a limited distance, which is very useful for current housing prices. A metal baffle was used as a decoration at the front and bottom of the lens of the machine. I think if the baffle is designed as a double baffle, the inner baffle can be automatically slid up to cover the lens when it is turned off, and it can automatically slide down when it is turned on. It will be more perfect, it can protect the effectiveness of the lens, without lack of artistic beauty.


The circular switch on the top of the fuselage is surrounded by a beautiful LED colorful two-turn design around the button, red and blue when power is switched, the normal boot will emit a warm and elegant yellow light.


All the interfaces of the Nut G1S mobile cinema are distributed on the back of the body. Although it is not only rich in interface configuration, but also can keep up with the mainstream, the basic commonly used interfaces are equipped with, such as USB3.0, USB2.0, mini AV interface , S/PDIFEarphone, high-definition HDMI digital interface, and RJ45 Ethernet interface.

UI interface and settings

In terms of system applications, Nuts G1S claims to be a nut OS system custom-developed for the mobile game theater of nuts, but with the experience of Xiaobian, it is only on the joint control platform launched by iQIYI and Galaxy (GITV). The nut's startup interface and some system settings have been incorporated. Currently, many intelligent boxes on the market also use this system, and not to mention nut customization.






As the machine is used by IGI for the licensee of the GITV, the basic options for iQIYI resources are also embedded in the system, such as the default definition and title of the playing video. Picture scale and so on.


The setting of the parameters of the machine itself can be realized by applying --- setting into advanced settings. Nuts G1S smart micro-investment compared to other brand products, in the advanced settings with more rich parameters can be set, such as traditional professional theater light bulbs have only three primary colors (red, green, blue) fine-tuning, audio decoding bias Settings and so on.



For enthusiasts, the projector's color bias is often the most important parameter, and the picture is cold or warm. Different films use different color temperatures to perform the screening is extremely elegant, and most of the smart micro-investments on the market are Without the advanced three-color debugging function, the addition of the Nut G1S smart mobile theater not only proved the strength of the nuts in product development, but also showed all users the meticulousness and professionalism of nuts in the product.


GITV online broadcast control test

With the recent strengthening of the State Administration of Radio, Film and Television, and the closure of 81 illegal online broadcast control platforms, many smart products have been affected, and as the only online platform with formal license authorization, it is the only source of revenue. . The Nuts G1S Smart Projector adopts the iqiyi online resource platform with formal license authorization in terms of content. There are a wealth of different types of video resources to meet the viewing requirements of people of different age groups.







In terms of search, due to the temporary development of the nut speech recognition function, the function is temporarily unstable. Although the G1S mobile theater did support voice recognition on the hardware, it is limited by software. Therefore, the function cannot be used on the G1S smart microchip. It can be realized, but after the completion of the follow-up software, the voice function can be achieved by upgrading the firmware.





Nuts G1S smart mobile cinema screen color overall warm tone, because the chip used is a Texas Instruments 0.45 "DMD chip, the effect is still fine in the video, but the performance in the text is lacking, while at the same level of clear picture When the details of the performance will appear more obvious jagged, especially when the screen size is more than 100 inches is more obvious, but for the normal viewing of these details will not affect the viewing effect, only a closer look It's obvious after the comparison.

For the warm color of the nut G1S screen, fine adjustment can also be made by adjusting the red values ​​of the three primary colors under the system menu, which has reached the personal viewing preference.

Local video test

As a mobile theater equipment whose main entertainment and interaction is the main theme, it cannot be compared with professional cinema projectors in terms of picture quality. Nuts G1S smart theater is hardly compatible with local video hard solutions. Not all file formats can be hard decoded. For example, ISO Blu-ray original files need to install a third-party player to open files for playback.


The nut G1S smart theater projection screen has rich colors, bright colors, and distinct color levels, but the overall picture saturation is lacking, resulting in insufficient overall picture saturation and insufficient level perception.


Because the brightness of the projection screen is limited by the light source, the G1S can not be used in a bright light environment, otherwise the screen effect will be seriously affected, resulting in the screen color is dim and completely flat.


Even if it is used in a pure black environment, the projection screen effect of the Nut G1S smart theater may have some differences compared to the original screen, such as the level of the details of the screen and the naturalness of the human skin color. The above picture shows a comparison of the original picture and the projected picture. From the figure, we can see that the nut G1S is slightly lacking in contrast, while the performance of the character's skin color is white, and the overall picture is red.

Software testing, thermal performance and power consumption

In terms of performance, due to the higher hardware configuration of the Nuts G1S mobile cinema and the deep optimization of the system at the same time, the performance of the P1 model has improved significantly compared to the previous test. Although it is not an absolute leader in the field of investment, it is considered to be middle and upper class. (PS: run points only as a performance reference, can not be used as a final basis to measure the performance of the machine, the quality of the machine is mainly depends on the quality of the picture, sound quality, stability and other comprehensive factors)




In terms of power consumption, the official power consumption of the Nut G1S official is 60W, but we measured average power consumption of 53.78 watts under continuous operation for 6 hours, which is still relatively energy-efficient in terms of energy consumption. Since the G1S Smart Projector can be used as a Bluetooth stereo in standby mode, about 2 watts of power is also generated in the standby (Bluetooth stereo non-operational) mode.


In terms of fan heat, because the nut G1S mobile cinema uses a semi-metal casing and a turbine exhaust fan heat system, the maximum temperature at the top of the head after continuous use for 6 hours at a room temperature of 20.5°C at room temperature is 33.5°C. The temperature at the air outlet is 44.3°C (fan speed is automatic mode), and the performance in temperature control is still relatively good. However, it is worth mentioning that the noise during the operation of the machine is somewhat large, especially when the cooling fan is running at full speed, the noise is even more obvious. This is also the common problem of the micro-project products that we have contacted so far, as a powerful fire in product development. Music Technology also did not overcome difficulties in terms of noise.

Professional software testing

The following figure shows the actual test of the 10th order of the Nuts G1S Smart Theater. The figure shows that the right two pieces of the black part are basically indistinguishable, and the left two pieces of the lower white can be easily distinguished. This shows that the nut G1S is in white details. The performance of the area is obviously better than the performance of black details.


Similarly, in the red, green, and blue primary colors of the 10th-order test, the rightmost two orders in the red color are basically indistinguishable, and the green rightmost third order is basically indistinguishable, and the blue most side third order is basically indistinguishable.


The following figure shows the color saturation test chart for the Nuts G1S Smart Theater. The white line should be at the standard spectral line. The yellow line is the actual color line of the G1S projection screen. Through the test screen, it can be seen that the nut G1S is projected in red and green. The performance is a bit over and the blue color is closest to reality. (PS: The closer the color transition spectrum is to the triangle, the more realistic the color performance is)


The following figure shows the R, G, B three primary colors of the G1S smart theater products. The top part is the true colors of the three primary colors, and the bottom part is the real shot image of the projection screen. You can see that the red color in the three primary colors is a bit too Green and blue are the closest to nature.


Disassemble internal structure

The Nut G1S uses a surround sound system with up to six speakers. The audio on the box shows that the bass performance is excellent. The performance of the midrange and high pitch is quite satisfactory.


Due to the turbine exhaust design of the Nut G1S, the noise during the operation of the machine is high. The following figures show the multi-leaf turbofan, acoustic cavity, WIFI and Bluetooth chip used in the G1S.


The Nut G1S uses a built-in antenna design and distributes multiple signal transmission/reception lines around the inside of the machine. At the same time, because the G1S uses the electric focus function, the following figure can be seen for the motor used for electric focus. In terms of fan heat, G1S uses pure copper blade thermal pad. Since the nut control method adopted by the G1S is Bluetooth control, we found that the inside of the lens located on the right side of the lens actually contained an infrared (IR) receiver head. The function of the receiver head was temporarily unknown.


Nut G1S uses four 512MB memory chips manufactured by South Asia, a total of 2GB of body to run the memory, in the built-in storage area uses a SanDisk 16GB embedded memory, the core processor uses the MSD6A918WV-WR chip, the chip is the majority Intelligent processing chips used in smart TVs are also one of the most stable smart chips recognized so far.


The nut G1S uses a DLP 0.4" chip and uses a DPP6401 DLP control chip to control the driver chip.


The nut G1S projection board uses a 32MB flash memory chip, which is mainly used to record projection color data and projection parameter information. At the same time also used CSR 8635 Bluetooth 4.0 main control chip, mainly used for Bluetooth audio signal transmission, as well as for the use of digital audio decoding NTP8212 chip.


In the core component optomechanics, the nut G1S uses the Anwar S2 light engine, the DLP chip is a Texas Instruments 0.45", with a physical resolution of 1,280,800, projection ratio of 1.2:1, 2.4 meters can project 100-inch screen, With 500LM brightness design.


Test summary, reviews

A good product, in addition to its outstanding shape design and eye-catching conceptual selling points, outstanding performance is the biggest weapon to win over consumers. Although the nut-G1S smart theater is unique in appearance design, it is rich in function, but due to the limitation of light source technology, the brightness of less than 500 LM (based on prototype test data) cannot be “cast” everywhere. situation. However, the analysis of one yard of code, G1S intelligent projection of the overall performance is definitely a leading product in the industry, even if only the actual brightness of the 458LM (in comparison to some brands marked 2000 lumens and actually less than 300 lumens ) is also in the leading position in its peer products, and its ANSI contrast ratio beyond 400:1 is a precedent in micro-projection products.


Where I am, is a movie theater - this is not a simple slogan. From nuts G1 to P1, in the G1 upgraded version of G1S, even the upcoming P2 products will be able to express this statement in a sensible way. At the same time, we also expect nuts to redouble their efforts to promote more grounding gas and more cost-effective. High, playable smart projection products to meet the needs of more diverse levels of consumers.


Comments:
