This time building a 4K home theater, two months ago, toss a lot of things. One of the most important of these things, one is the first to start Sony VPL-VW328 4K projector, this is the end of this Panasonic DMP-UB900 4K UHD Blu-ray Disc player. This machine is not licensed domestic, can only Haitao or purchasing, have been very early to own orders, I did not expect this machine sold in foreign countries is really good, so long out of stock, so toss 2 More than a month later I finally got into my arms. This was the last piece of the puzzle. Officially built a 4K home theater.
Speaking of this machine, we first mentioned something else. From the second half of last year to the first half of this year it could be said that 4K officially entered the family's year. Although 4K TV and projection had been interviewed for more than 3 years before, but due to the real The severe lack of 4K resources has made the 4K chicken unable to come down to 4K eggs. Until last year, the Blu-ray Association finally standardized the 4K ultra high-definition indicators, 4K development entered the fast lane.
With a unified set of standards, each household will have a good job, immediately Panasonic first released a 4K drive is UBZ-1, but the price of more than 2W renminbi and only sold in Japan makes this machine more Like a sign rather than a formal product, after the major movie companies began to launch 4K UHD Blu-ray discs, which means that the official arrival of the 4K home theater era, Samsung introduced cheap 4K disc player K8500, Panasonic will UBZ-1 After the hard disk was removed, it launched the UB900 for the global market. Soon after, it introduced the UB900 with the UB90, and Philips and Microsoft also launched 4K drives. Interestingly, Sony Corp., the former pioneer of 4K, has not listed its own 4K drive system so far, including the new PS4 that has just been released, which has caused many disappointments in cable powder and made Microsoft laugh at it. It is estimated that Sony does not want everyone to Use PS4 to view 4K Blu-ray discs. After all, Sony's own UHD disc player will be available immediately. It is this situation that made me decide to establish a new home theater at the beginning of the 4K home theater, to save money. So many things do not have to choose how, after all, choose too little. The specific procurement plan will be set immediately. Then build it step by step.
How to create a 4K home theater
What does it take to talk about a qualified 4K home theater? Everyone would say that this is not nonsense. It can display 4K devices, and it can play 4K devices. Plus, supporting 4K cable is not OK. In fact, it is far from simple to do a basic qualified 4K home theater. First talk about 4K display devices, and now even mobile phones have 4K, 4K display devices are already common in everyone's life, as home theater displays nothing more than TV and projection, for most people, obviously 4K TV It is a more economical and convenient choice, then how big a 4K TV needs to be, at least according to your viewing distance, according to Sony's suggestion: the best viewing distance for a conventional 16:9 screen 4K video is 1.5 times the screen height, about this distance, the best balance of picture quality and picture size, of course, this is only Sony's point of view, comprehensive standards, generally speaking about the screen height is about 1.5 times -3.0 times the viewing distance More appropriate, and then it is difficult to reflect the advantage of 4K in the 1080P in resolution, to the living room TV is more conventional 65-inch to count, the best viewing distance is about 1.2m-2.4 meters or so, we can In contrast, to see how much TV is needed to meet the requirements, there is no doubt that the viewing distance of the average family living room TV is around 2.5-4 meters, so we must enjoy the effect of 4K resolution. It is no less than a 65-inch TV is a must, no matter how small, then we should move stool estimate did see the front. Projection of this size is good to meet, most of the projection is 100-inch screen, the conventional viewing distance is certainly enough, but the price of 4K projection is still high above, regardless of Sony's true 4K projection or EPSON, JVC includes new BenQ's interpolation 4K projection is currently no less than 30,000 yuan in price, and to play 4K projection effects, the screen is at least a few thousands. And both TV and projection need to support HDR technology and have an HDMI interface that supports the 4K Blu-ray standard. Therefore, whether you want to use the advantages of 4K resolution in TV or projection, you cannot achieve certain economic strength. Of course, again, the 4K standard is not just a mere improvement in resolution. Other requirements, such as HDR technology, higher color depth and color gamut, make UHD completely exceed 1080P in all aspects, so even if it is difficult to feel The advantage to resolution is still significantly improving the viewing experience in other aspects. Then there is the 4K resource. The real 4K resources that meet the 4K Blu-ray standard have almost no formal channels in China, and only the paid viewing provided by Sony’s 4K player (and these movies are not based on the 4K standard. In terms of meaning is not 4K Blu-ray), domestic streaming media and telecommunications TV so-called 4K effect is not as good as the ordinary 1080P Blu-ray disc is purely flicker, then there are some online demo film resources (this is a relatively reliable point, after all, the demo film In order to promote the widespread use of the product, no one has to restrict it, so there is a joke to spend tens of thousands of dollars on 4K TV every day to see beauty eating roast duck. Recently, the 4K Blu-ray discs released Dongfeng, some so-called "4K movies" appeared on the Internet. It is clear here that the current 4K Blu-ray will not be cracked and will not be cracked in the short term. All so-called 4K movies on the Internet are either 1080P or 1080P. Transcoding, a little better from the Sony 4K player download is made by stealing out and transcoding compression, how these so-called "4K movie" download effects should be clear, with real 4K Blu-ray completely Not a magnitude. So the best way to really enjoy the effect of 4K Blu-ray is UHD Blu-ray Plus UHD Blu-ray Disc Player. Nowadays, Taobao also has a lot of 4K discs, most of which are equipped with Chinese subtitles. Another point is that all interfaces need to be supported, otherwise the tragedy will not be recognized. Therefore, at present, a qualified 4K home theater still requires a certain amount of economic investment to achieve, not to mention that the new 4K disc with soundtrack is mostly Dolby Atoms or DTS X, which means you still need a Supports panoramic sound amplifiers and enough speakers.
So much to go back to this topic. The 4K disc drive currently has no choice but Panasonic and Samsung (Philips and Microsoft were not listed at that time). This is nothing to hesitate. Since UB900 was released, the world’s major prizes have been mad, and it must be it. The order was placed immediately and then it was a long wait. This machine's technical parameters and selling points do not go into details here. In a word, this machine is the current top picture quality. What OPPO Pioneer Philips is on the sidelines, including ordinary Blu-ray discs. The sound quality supports Hi-res, hard-to-get DSD, various fever-grade components, and is also a powerful digital music player. We would like to see the official website to see just fine. Poke here
Given the current price of the British pound, Indo-Asia should be the cheapest, do not want to trouble Taobao purchasing. Note: Deya specifically stated that it will not be issued in mainland China.
The box is not big nor heavy, after all, the weight of the machine body is about 2.4kg. The vicissitudes of the outside of the box have shown that it is not easy for him to come to China.
THX certification and 4K various technologies are marked in a prominent position
Open the box, there are not many things except the machine body, the box is not big, the machine body is thinner than the box.
Power cord and remote control
With a few 4K Blu-ray discs together, 4K discs are not a division of the 4K discs, except for the leap in quality. This means that whatever you buy is the European version of the machine, the US version of the machine. Or Japanese version of the machine, regardless of the United States version of the dish can see the European version of the dish can be universal, so no jailbreak.
Although 4K Blu-ray is still not rich, it cannot be said that it is scarce. Basically, all new Hollywood movies started to issue 4K Blu-ray last year. Some of the big movies made in the past were also 4K discs after 4K repair. . And the price of 4K discs is not much higher than ordinary Blu-ray. The 4K era has already arrived inevitably.
HDR is standard on 4K movies. The UltraHD Premium in the lower right corner is the 4K certification mark of the UHD Alliance.
General instructions (Because of the European version, too many languages, so the paper manual is a quick start guide besides German), the CD is the main manual, an HDMI2.0 cable designed for 4K high bit rate supports 18G bandwidth , BTW depends on the real 4K (not domestic streaming media, radio and television and even the kind of 1080P original can not match the pseudo 4K) must use the HDMI2.0 line to support 18G bandwidth, in order to deal with 4K movies The improvement in the aspect is not merely an increase in resolution. Even if the quality of foreign streaming media 4K is not as good as 1080P Blu-ray, after all, it is limited by the network transmission rate, signal interference distortion, network stability and a series of restrictions. The so-called 4K video in China is even more tragic. 4K is not only a 4K video capture, but also includes post-processing and transmission of 4K video. All of these are new standards and requirements. Now many domestic video websites and telecom companies have launched the so-called 4K. The video program, the quality of the picture did not meet the requirements of 4K Blu-ray, the quality of the original even 1080P Blu-ray disc is far, only Ha ha ha, of course, at least people have the copyright is still worthy of recognition, after all, bragging is not illegal.
Uncover the protective film to see the fuselage, the top of the fuselage as well as the front panel with a mirror surface, the advantage is that the stylish beauty of the shortcomings is too easy to stain the gray.
The top highlighted position again shows the UHD Blu-ray machine's identity
The machine body does not have a physical button, only the two touch buttons, an opening key and a storage button, this design is similar to the Philips BDP7750 I used before, after the boot test found that the two keys boot is no backlight It is impossible to use these two keys in a dark viewing environment. It seems that Panasonic basically did not intend to use these two keys during the viewing process.
THX certification
Overall view of the machine
Put together with iPhone6
Open the front mirror panel is the operating area, the left is a 4K Blu-ray drive, backward compatible with ordinary Blu-ray and DVD, ordinary Blu-ray drive is not able to identify 4K Blu-ray disc.
The middle is the display panel and the front interface, in addition to the conventional USB interface, the more characteristic is to provide an SD interface, support for SDXC, this is the first time on the Blu-ray machine to see. Obviously this is for the current camera service, after all, with the increase of camera pixels and a variety of new cameras began to support 4K video capture, direct playback with a SD card is a very intimate and practical design. Must give Panasonic a thumbs up here
Rear view of the fuselage, all audio and video interface gold-plated, audio output terminal gold plating is more common, a little bit on the disc amplifier will be gold plated, but the HDMI gold plated interface is the first time to see, including Philips flagship Blu-ray machine BDP9700 and Tianlong flagship Power amplifier AVR-X7200WA's HDMI interface is not gold-plated, Panasonic's use of this machine is very full.
On the left is the power interface, European version of the machine voltage can be used directly in line with domestic requirements, the US version of the Japanese version to increase the transformer. Due to its compact body, it is equipped with a cooling fan. On the edge is the LAN port of the network cable, but basically it is now connected to WiFi, and it is estimated that there is no chance to use it. The core HDMI interface has two audio and video outputs, a special sound output, easy to separate sound and picture, I like this, after all, there is specialization in the surgical industry, although Tianlong amplifier known as 4K but imaging technology and deep in the field of imaging for many years Panasonic’s flagship 4K drive is still incomparable, and there are multiple incense burners. Minimizing the signal transmission path helps improve the picture quality.
Then there is the audio output terminal, support 7.1 channel output, stereo 2.0 channel output, optical fiber output and coaxial output.
The nameplate of the fuselage, assembled by the Czech Republic, you may think that this is the first thing I bought in Czech Republic. I can only say that you are a figure. The earliest Czech manufacture I bought was an etched piece of a bull devil. )
The remote control works well, feels good, the front is the same glossy design, black and white on the white is very clear, the key arrangement is more reasonable than the Philips disc drive
Remote control from China
White backlighting. The remote control that is used in all home theaters is best equipped with a backlight. Philips is disappointing.
Put the machine on the equipment rack, because the machine is not heavy and the heat of the disc player is not large, so simply on the Philips disc drive above, you can see the size of the Panasonic UB900 is smaller than the Philips BDP9700, the weight is also To light 1.5kg, but do not think Panasonic's machine in the use of materials less things, on the contrary, according to the use of foreign professional media and enthusiasts to see the quality of the effect of even playing ordinary Blu-ray but also strong out of the following big guy, It's no surprise that Vanguard and OPPO’s flagship are eliminated.
Connect the power supply and HD cable, turn on the power, turn on the projector
Home theater remote controllers come together, only Philips's remote control is not backlit, the size of the reference to the right fruit 6, are big guys.
First set the language
Connect home WiFi
Then enter the main interface, UI is a bit like Sony's PlayStation system, the background color can be adjusted, you can set the background image. Left-to-right distribution is video, music, pictures, home network entertainment, online services and settings, and it will be slowly explored and debugged later.
Finally, at the most important moment, what is the effect of 4K Blu-ray? The test uses the 4K Scenery Documentary "The Scenery of Time." He was chosen because it is relatively natural and natural that there are not too many traces of retrofitting as a documentary. However, due to the early filming time, this film does not have HDR effect, so the HDR effect still has to pass through the follow-up experience. How to take a 4K image should be more headache, because I do not have the telephoto lens on hand, so I had to stand near the screen to take pictures, but it is difficult to make the focal plane parallel to the screen, it is difficult to shoot the screen real The effect, so we take a look at it, and the website compresses the picture more powerfully, so the picture shown in the post is certainly not a small gap with the actual viewing effect.
As mentioned before, the 4K system has requirements for high-definition interfaces, 4K Blu-ray transmission receives HDCP2.2 protection, so the HDMI interface of the display device must support HDCP2.2, otherwise it will directly drop from 4K to 1080P when playing 4K blue light. Very important.
Screen shot lens is 35mm F2.8 fixed-focus full-frame lens, body: Sony A7R2, shutter 1/60, ISO1000, manual focus, JEPG straight out, then compressed to about a quarter of the original size when uploaded, Without any post-processing.
Let's take a picture of the whole, which is about three meters away from the curtain.
The rest of the pictures are basically shot from the screen about 2 meters, parameters as above.
Originally wanted to do a comparison test between 1080P and 4K UHD, but this post already has enough content. This test is reserved for future special opening instructions. As the culmination of the current home image quality, this Panasonic DMP-UB900 really made me shine. Compared with the well-performed 1080P Blu-ray such as Avatar, Hugo these image quality models have at least increased a level, is completely an eye The difference, the appearance of the title, my feeling is described by a picture:
But after reading it, I got into deep thinking
Indeed, the new standard of 4K Blu-ray brings a whole new picture quality experience, plus a feverish 4K flagship player, it can be said that there is no return to the feeling. However, it will take a long time for 4K home theaters to be popularized. After all, there are currently no national 4K discs and 4K disc players in the country (Xbox ones should be expected to become the first 4K disc player in the country). But there is no doubt about the overwhelming picture quality of 4K Blu-ray. I just want to say that you have movie enthusiasts who are in danger.
The next article will specifically introduce the 4K projector debugging, 4K disc player settings, the most important is the direct contrast test of 4K Blu-ray with 1080P, so stay tuned, thanks for watching.
The CCP1000 series high-voltage power supply module is a single-phase 220Vac input modular high-voltage power supply.
