2016 was known as the 4K first year, because in this year, UHD Union officially issued the 4K/HDR certification mark, and in the same year, the sale of 4K UltraHD Blu-ray discs and Blu-ray discs in the same year also signaled the official coming of the 4K era. Before this, 4K TV has been gradually popularized, paving the way for 4K Blu-ray to enter ordinary families.
As can be seen from the above, a set of the most simple ultra-high definition Blu-ray playback system is mainly composed of a 4K HDR television, a 4K UHD Blu-ray player and a 4K Blu-ray disc. Some people say that the popularity of online 4K sources is increasing. Why do you still need Blu-ray? Contrary to the bandwidth limitation, the bit rate of online video is usually compressed to a particularly low level. Although the resolution can reach 4K, the picture quality performance is still very different from that of 4K Blu-ray single-disc 50G or more. So, in order to experience true 4K HDR content, Blu-ray is an essential part.
Panasonic is a member of the UHD Alliance and is also an early manufacturer of 4K UHD Blu-ray players. For example, for the high-end DMP-UB900 Blu-ray players introduced in Europe and the United States, Matsushita introduced an entry-level DMP-UB400 to the Chinese market this year. Blu-ray machine, which is the protagonist of our experience evaluation today.
Simple appearance Panasonic DMP-UB400's body is very simple, the thickness of this Panasonic TV's base is not high, in his hands is also lighter, which means that can be placed at random. The top is simple enough to have only the switch and back disc key.
The front is a full transparent cover, which automatically pops up when you return the disc. You can see that there is a USB 2.0 connector and power indicator when you eject it.

At the same time, the machine also comes standard with a remote control and an HDMI cable.
It is still a multi-key remote control.
Due to the high code rate of 4K UHD Blu-ray audio and video, the HDMI cable has a high transmission capability. The standard HDMI cable can achieve 18 Gbps/s and meet the demand for Blu-ray.
UHD Premium Certification "True 4K"
In addition to supporting UHD Blu-ray, this Panasonic DMP-UB400 can also play Blu-ray (including 3D), DVD, and CD. It uses its own Ultra HD Blu-ray 4K processor that supports the BT.2020 video standard and supports 4K 60p/50p output.
The DMP-UB400 is equipped with 4K Upscaling picture quality enhancement technology. By directly converting Full HD chroma and brightness signals to 4K signals, high-precision image processing is achieved, and the best results can be achieved with 4K/UHD TVs. .
Of course, for SDR TVs, DMP-UB400 can also convert Ultra HD Blu-ray to SDR by optimizing the tone remapping technology. This feature can make the best use of the features of 4K content and provide more than Blu-ray on SDR TVs. Good experience.
In the current popularity of wireless, the machine also logically supports DLNA functions and can play MKV, MP4, JPEG and other formats on the NAS. On the audio side, in addition to the traditional WAV/FLAC/WMA format, DSD (5.6MHz/2.8MHz) and ALAC music files can also be played. Simply connect to your home audio system to enjoy music sources that are the same as studio sound quality.
Why is it true 4K? Because only the 4K Ultra HD Blu-ray standard, which is specified by the Blu-ray Disc Association BDA (Blu-ray Disc Association), is the true 4K disc player, the Panasonic DMP-UB400 is one of the standard disc players.
Since it complies with the 4K Ultra HD Blu-ray standard, it means that the MP-UB400 disc player supports hard-coded HEVC H.265 encoded video, supports high frame rate (60fps) output 4K resolution video, and supports HDR high dynamic range technology and many more. Among them, HDR technology supports a brightness output range of 1000 to 10,000 lumens, which can provide clearer and brighter details of shadows.
A qualified true 4K Blu-ray player must support a transmission rate of at least 100Mbps. The Panasonic DMP-UB400 uses a dual DHMI output method. One HDMI interface is responsible for outputting audio exclusively, and the other is used for transmission of video signals. Ample bandwidth.
The video quality tests used in this test include three-disc 4K UHD movie "Fantasy Rafting by Juveniles". In addition to a 4K UHD BD66 disc, there is also a 3D and ordinary 1080P Blu-ray Disc. In order to compare the difference between 4K and ordinary Blu-ray discs, we have also prepared a 1080p Blu-ray Disc with "Youth School Fantasy Drifting."
The test TV is Panasonic's recently released 55EX700C, which supports 4K HDR.
Look at the player's menu section first.
Select the video to enter, there is a disc and USB optional.
As mentioned earlier, the DMP-UB400 can access the contents of the NAS in the home LAN.
There are more options for HDMI.
Panasonic DMP-UB400 Blu-ray player's menu is very simple, the first time the difficulty is almost zero.
Whether it is 4K UHD or ordinary Blu-ray discs, DMP-UB400 reading is very smooth, with the point of progress, fast response.
We use SLR cameras to record screen shots, fix camera parameters, and restore actual images as much as possible.
Let's take a look at the basic information of two dishes. The above is a 4K UHD Blu-ray disc, supports HDR, BT.2020 color gamut, 10bit color depth; the following picture shows the ordinary Blu-ray disc, SDR, BT.709 color gamut, 8bit color depth.
Let's look at the comparison of a group of landscapes. This group is mainly green. It can be seen that the brightness of the 4K UHD version is significantly higher, the picture is more transparent, the green reduction is more accurate, and the ordinary Blu-ray version is somewhat reddish in tone.
Let's look at the contrast of a group of people.
Similarly, the ordinary Blu-ray version is still reddish in tone, and the character skin color is not accurate. The 4K UHD version is closer to reality. Zooming in on the details, 4K UHD characters face is very clear, and even can see the stubble of a beard root, ordinary Blu-ray version zoom is relatively fuzzy, beard is difficult to distinguish.
Look at the performance of a group of night scenes.
Moonlight shines on the sea, and 4K UHD shows great advantages in supporting HDR. At night, the picture is brighter and more stars can be displayed. The hull outline is also clearer, and the dark details are clearly better than the regular Blu-ray version. But in fact, ordinary Blu-ray version can have such a performance has also been very good, thanks to Panasonic DMP-UB400 4K HDR lifting technology, and Panasonic TH-55EX700C excellent display.
In general, 4K UHD Blu-ray discs not only have obvious advantages in terms of sharpness compared to ordinary blue light, but also perform better in detail in color reproduction and light and shade.
Summarizing the unstoppable arrival of the 4K HDR era, as an entry-level 4K UHD Blu-ray player, the DMP-UB400 has been fully qualified to play ultra-high definition Blu-ray video regardless of its value, workmanship or picture quality. Through the trial of 4K UHD Blu-ray discs, the 4K HDR video also has a huge advantage over ordinary video. With the increase of 4K UHD Blu-ray discs, content will no longer be an obstacle to the popularization of 4K Ultra HD, and having a Blu-ray player with UHD and BDA (Blu-ray Disc Association) certification will be the best choice for audio and video enthusiasts. Choose, and, as a product of the National Bank, you don't need to go to the sea to make an effort.
