Extremely Meterless Super TV Test TV Projection in One

Last month in Beijing, Mr. Zhaike attended a very peculiar press conference. A startup known as "Rice" launches its own television products but has no screen. They call it a "super-screenless TV" (specific model is Z3).


TV has no screen? It sounds a bit subversive. Here is actually a word created by Mi Rice. The so-called “non-screen TV” is an Android TV box plus a screen to become a TV. However, the screen here is not a solid LED screen, but is replaced with a projection screen. form. We can watch online videos, download and play Android games through this “very meter”. Of course, as a device with projection properties, it is also very perfect in this regard, supporting HDMI, VGA, Airplay, App push and other forms of projection.


After the press conference, the guest house gentleman applied for a trial experience to the staff of the meter and the experience report of the house guest playing the game for two weeks.


Projection screen


When I first got the real machine of the meter, I felt a little surprised. It is much smaller than a traditional projector, probably a bit smaller than a revised version of "The Steve Jobs", and is easy to carry when you go out.


The appearance of polar rice is relatively common, common black and white, plastic and glass, is not new. Its back is covered with a variety of interfaces, including Power, TF, USB, VGA, HDMI, S/PDIF, AV, LAN RJ45, 3.5mm headphone, RF antenna, etc. Listening to so many people may be dizzy, but these are It really does work in the face of different scenarios. For example, S/PDIF and AV are divided into high-pursuing and low-pursuing audio users. (Tucao sentence, three USB ports are too many points).

The above said that it should be related to the company's personnel. The founding team that introduced them at the press conference was mostly from Mstar. They are good at hardware engineering rather than industrial design and product design. Engineer thinking always thinks that a product must be perfect enough to face various scenes. Few will make choices. Therefore, there is not much to say to the hotel guest here. There are also several details related to this later.


Open the TV screen, first of all is a huge screen into the eye (where the meter is at least 3M away from the projection wall), after the focus adjustment on the top pulley (the projector has a tuning process, similar to the camera focus), the entire The screen suddenly has a kind of amazing sense: a real big screen, a clear and bright picture.


According to the official, this meter is projected on a 100-inch screen (up to 300 inches) and has a peak brightness of 1500 lumens. The guest house is open to the office in a sunny day, with white curtains and a normal light environment. It looks relatively clear, but it is not bright; at night, the headlights are clear and bright. It seems that the rice is not suitable for viewing in a strong light source environment. Generally, there are curtains in the home.


In addition to curtain shade, the poles are in use and there is no shelter in front of them. For example, if a person or pet passes, the projection screen will be blocked. When placed here, it is best to reserve 2 to 4 meters of space in front of it. If it can be better to use a tripod or ceiling to lift, this problem can be avoided.


When it comes to the properties of the projectors, there is a topic that cannot be avoided: Projection light source life. Current portable commercial projectors have an average lifetime of several thousand hours for light sources and tens of thousands of hours for LED light sources. The polar meter uses an Osram LED light source. The official said that the shortest life span is 20,000 hours and the longest is 50,000 hours, and at least 9 hours per day can be used for 6 years. This can not be directly tested, house visitors to retrieve a more common LED projection, life is not far off, so this should be no problem.


Playing

OK, the projection properties talked about for a long time, the following talk about the box properties, this is the protagonist.


To tell the truth, the paper parameters of the rice are not high. It uses the Mstar dual-core, which is believed to be obsolete with certain parameters. However, the homeowner does not think so. Internet boxes usually use AMlogic chips. By April of this year, they have rushed to quad-cores. However, AMlogic is not a set-top box or TV box dedicated chip, but it is worth mentioning in the decoding capability. Of course, their The operating ability is also very good. Mstar is the set-top box chip manufacturer of the eight children. In this regard, their chip stability and integrity can be trusted.


So the discussion is about using effects. Specifically, the pole meter supports almost full-format 1080P decoding, which is responsible for a dedicated independent decoder chip, so the playback effect is also OK. During the play, the meter is hot but not hot. Here's a tantrum about the sound of the fan. The official said that the next version of the firmware before the sale is expected to fix the sound too loud.


Another experience is also related to the chip. When playing a game, you can completely mirror the projection screen into the mobile phone operation app to achieve dual-screen interaction. At this time, we can use our hands on the screen of the mobile phone, and the projection screen will follow. This experience is very interesting, both sides of the screen are displayed.


This is a new technology, through a dedicated auxiliary core to capture the real-time streaming of the projection screen to the mobile phone, in the use of the two sides to maintain the same picture. Well, the home-hotel guest here just wants to say: The technology is really novel, but both sides of the screen display a picture, obviously not a good solution. The characteristics of engineering origin are reflected here again.


When playing a meter, the basic box operation is basically the same, open the projection, select the content. In the specific playback experience, there are two places worth special mention. The first is 3D video playback, with shutter-type 3D glasses and a super-large screen with a height of up to 300 inches. The sensory performance is very strong. The 3D effect is almost immediate; the second is an infrared remote control equipped with a scattering signal on the back. The round beads, so the remote control of the pole meter can certainly bend the angle of the operating system, house guest Jun initially thought it was using Bluetooth technology.


content

The system of pole meters is the same as the common TV box. It is based on the Metro-like interface modified by Android 4.2.2.


Content, the polar meter is divided into three blocks: video, games, applications.


On the video, the current number of meters has already obtained the Chinese number license, but the firmware that accesses the Chinese content library has not yet been released. Therefore, what we are using now is the content of the preloaded various video apps.


In terms of games, there is no special requirement for pole meters. Ordinary Android mobile games can also be installed and run (the system can install third-party apps). Here the practice of the edge pole is not the same, other box manufacturers follow the host game habits, access to the game mostly support the handle operation; pole meter is all through the mobile app to operate, through the App to make a large sensor, handle, etc. Here, the specific approach is mentioned above: image real-time mirroring.


Applications, the same ordinary Android applications can be used, very like a wide-screen Nexus 7 tablet, Nexus 7 can be installed and play applications, very meters can also be.


to sum up

Having said so much, everyone in the heart must have had an impression on the rice. Below we summarize the views of this “geek toy”.


advantage:

Big screen experience is good, put 3D video best, almost immersive


Small and portable, suitable for backpacks to carry around, can be used everywhere


The engineering details are very good, including infrared signal enhancement of remote control, automatic trapezoidal correction during projection, etc.


Disadvantages:

The projection form has requirements for placement, and the official has not yet introduced accessories adapted for various scenarios (such as lifting, positive tripods, standing tripods, etc.)


The system is not perfect enough, there are several features that affect the experience also need to wait for the new firmware update


There are too many interfaces and there are some redundant product features. In this regard, officials may consider making downsizing according to the characteristics of typical users. Almighty also often means that the focus is not enough.


Hotel guest reviews: How to define the product to this meter is not important, transform the projector? Transform the TV? Or build a future TV? These are just a definitive symbol after hardware cross-border. As a cross-border smart device that sells for 2,999 yuan, the opponent facing Miji is no longer the traditional old projector equipment, but the intelligent TV box and smart TV that are on the market. Think about now a 47-inch millet TV is 2999 yuan, an Android box plus 30-inch display is also about 3,000 yuan. These three products face three special scenes, but at the same time they compete for the dominance on the concept of "smart TV."


The advantage of the pole meter is that the video and audio entertainment experience created by it is completely beyond people's expectations; the disadvantage is to break through people's psychological inertia. From the "real" screen to the "projection" screen, the implementation of this view is still a task.


Finally, let's take a look at some of the issues that the homeowner Jun thinks it is necessary to single out.


1. As a TV, how does it fit?


House guest Jun: I tried many ways, and finally felt in front of the sofa in the living room, hanging from the ceiling, back projection, sleeping on the bed and projecting to the ceiling. These three scenes are more comfortable.


2, as a projection, how does it function?


House guest Jun: Business tools to explain it. The heavy rice weighs about 1kg, which is equivalent to a normal laptop and its size is smaller. It can be HDMI, VGA projection, but also Airplay, mobile App projection, the function is almost perfect. At this point, homeowners think that no better equipment can be comparable. The biggest problem with the so-called projection mobile phones and projection flats is that the screen shots are not large enough or obvious enough, and the pole meters are solved very well.


3, which group is suitable for use?


House guest Jun: The official saying is that the young generation of renters, this part of the group may not have television or old landlord TV, and even the living room is not, very rice is very suitable for this scene. However, homeowners think that you can add a few typical scenes.


Company or personal portable projector (display anytime, anywhere)
