[Home Theater Network HDAV.com.cn] Today, the establishment of 4K Ultra HD private home theater system, with more and more ultra high definition signal sources, more ultra high definition signal sources and corresponding AV amplifiers select. For domestic audio-visual enthusiasts, the UHD 4K Blu-ray player that we are looking forward to at this stage still has not officially entered the domestic market, and we still need to purchase UHD 4K Blu-ray player and Blu-ray disc through foreign channels. In addition, the network ultra-high-definition streaming media and audio services that have been very popular in foreign countries still fail to fully enter the domestic market. For example, the Netflix service platform that can provide UHD and HDR movies or TV drama resources does not enter the country, but players in Hong Kong and Taiwan can It is indeed very jealous to reflect its wonderful picture. Nevertheless, we believe that many domestic network streaming media platforms will soon bring UHD and HDR video and video programming services, and as more and more UHD 4K Blu-ray sources emerge, it will inevitably lead to full entry into the domestic market. .
More traditional and conservative choice, UHD 4K Ultra HD Blu-ray player
Choosing a CD-ROM signal source seems to have become a habit for many audio-visual enthusiasts. From LD, VCD to DVD, Blu-ray, it is logical to choose the latest UHD 4K Blu-ray, but unfortunately it has not yet entered the domestic market. It really made quite a lot of people feel quite disappointed. However, there have been reports recently that OPPO is about to launch a new generation of UHD 4K Blu-ray players in China. It seems that it doesn't take too long, and we can easily enjoy Ultra HD Blu-ray. If you are sure to choose this relatively conservative Ultra HD video source, you can start buying more and more UHD 4K Blu-ray discs from foreign websites or directly to Hong Kong. In the selection, in addition to the choice of content, but also need to pay attention to whether this UHD 4K Blu-ray disc has HDR high dynamic range technology production, and even better, the late Blu-ray suppression is 4K native, and Not 2K specifications, so you can enjoy the original 4K Ultra HD movies. It is a pity that the UHD Blu-ray movies produced in the real native 4K post production are not many, and many of the UHD Blu-ray movies that have just been launched have not been as good as they were supposed to be, no matter the delicateness or color of the picture. Performance is similar to the full HD Blu-ray version.
In the choice of UHD 4K ultra-high-definition Blu-ray player, it is already quite rich, and the performance of many products in audio and video is quite outstanding, and the price is not too expensive, and the price of the previous Blu-ray player The level is not much different. Undoubtedly, UHD 4K Ultra HD is still a relatively stable 4K signal source, and it also has the most abundant movie resources. What is more attractive to audio and video enthusiasts is that UHD 4K Ultra HD Blu-ray movies will provide HD surround sound. Audio tracks, and some even use immersive 3D sound effects such as Dolby Atmos and DTS:X, which are important advantages that are currently not available in popular network video streaming platforms.
Most of them have regional restrictions but rich content, and all of the ultra-high-definition streaming media service platforms.
Compared with the traditional conservative UHD 4K Ultra HD Blu-ray, the audio and video streaming service relying on the Internet is known as the new generation of signal source method to replace the traditional optical disc. After entering the ultra HD era, the first high-definition program source we saw was not from Blu-ray. Disc, but the way of streaming. Sony is the first brand to launch 4K video services in China. It is realized by its 4K hard disk player in the form of paid download and viewing in a specified time. The 4K movies provided in it are all movie movies produced by Sony Pictures. . In the past two years, some domestic online streaming media service platforms have begun to produce some 4K Internet TV dramas, providing a way for domestic audio-visual enthusiasts to acquire 4K movies and TV programs. However, several large-scale network ultra-high-definition video service platforms that are very popular in foreign countries have not really entered the domestic market, such as Netflix, Amazon, etc., making it impossible for domestic players to watch more diversified movies and TV series. However, some foreign film and television service platforms have also accelerated the pace of global market expansion. For example, Netflix has now entered the Hong Kong and Taiwan markets, providing local audio-visual enthusiasts with a wealth of high-quality 4K movies and TV drama resources, many of which are still With Dolby Vision and HDR10 HDR 4K Ultra HD movies and TV programs, you can take advantage of the new 4K flat-panel TV and home theater projectors. However, due to the influence of network bandwidth, the effect of surround sound audio is still quite different from UHD 4K Blu-ray. If you have an immersive 3D sound system, it is recommended that you choose UHD 4K Blu-ray with better sound performance.
High playability, 4K network hard disk player
In addition to the above two mainstream 4K Ultra HD signal sources, the 4K network hard disk player is a 4K video source with a relatively high playability. This method is suitable for players with strong hands-on ability to obtain various 4K ultra-high definition video resources by different means. These 4K players are basically capable of realizing HDR 4K ultra-high definition video and immersive 3D sound output, and have certain network streaming media playback functions. They can play high-definition movies, TV series and variety shows through domestic related network video service platforms. Wait.
Overall, the above three are the current mainstream 4K video resources acquisition methods, of which UHD 4K ultra-high-definition Blu-ray still does not really enter the domestic market, and the ultra-high-definition streaming media service platform needs a certain time to fully popularize, 4K network hard disk The player is not suitable for all audio and video enthusiasts. However, they all have their own characteristics. If the budget is sufficient, users may wish to include them all. Of course, in addition to these, high-end players can also choose the ultra-high-definition cinema synchronization system, which can watch the latest movie blockbusters in the cinema for the first time, but the overall audio-visual system construction needs to be reconsidered. After all, the cinema synchronization system is professional. The DCI digital cinema standard has its own unique system for signal transmission and connectivity.
Mainly look at the HDMI interface version, basically a new generation of AV amplifiers and processors can do the job
When you upgrade your signal source, you need to consider whether you need to replace the AV amplifier or surround sound processor. The key is whether the model you are using supports 4K and immersive 3D sound transmission and processing. The best way to judge is to look at the version of the HDMI interface that is equipped with 1.4, 2.0 or 2.0a. For the 1.4 version, if you only play the normal 4K/24p signal, there is no problem, but to play a higher specification 4K/60p or even HDR 4K signal, you need to choose 2.0 or above. However, there are some AV amplifiers or processors. The manufacturer does not clearly indicate the HDMI version, but it indicates that the HDMI interface supports HDCP 2.2, which is compatible with the playback requirements of UHD 4K Blu-ray and Ultra HD network streaming services. With the Japanese and European and American brands gradually completing the technical upgrading of the new generation of AV amplifiers, most of the new machines are compatible with Dolby Atmos, DTS: X and HDR 4K audio and video technologies.
to sum up
In fact, 4K Ultra HD is not a new concept. Just like 1080p Full HD, in the past few years, the majority of ordinary consumers can understand its meaning and advantages, just lack of program source. With the support, it is difficult for users who have purchased 4K flat-panel TVs and home theater projectors to fully experience the differences brought by the 4K Ultra HD system. In the home theater, from the second half of this year to next year, high-end 4K home theater projectors will continue to emerge, coupled with the maturity of AV amplifiers and processor technology, as long as the 4K signal source can enter the domestic market with enthusiasm, It is expected to usher in a new wave of 4K private home theater system, especially in the custom installation market.

1. Why fiberglass antenna is not suitable for indoor use? A: Many people may have noticed that international brands such as Linksys or DLink typically use only 7dB, 5dB and 2dB antennas, while 9dB or higher gain indoor omnidirectional antennas are rarely seen in the market. As far as we know, the 7dB antenna has fully met the requirements of indoor use. The antenna above 7dB has been used. Due to the small Angle, it cannot give full play to its advantages. Therefore, we recommend using an omnidirectional antenna above 9dB for outdoor use. As for someone, it is good to say indoor wall effect, this statement is unable to prove, also need not believe too much. 2. Why are omnidirectional antennas and perpendicular angles called? A: Generally speaking, an omnidirectional antenna is an antenna with a horizontal radiation Angle of 360 degrees and a vertical sector. The Angle is usually around 6 ~ 15 degrees. The higher the gain, the smaller the vertical Angle. For example, the radiation Angle of the 9dB antenna can be about 14 degrees, while the radiation Angle of the FRP antenna can be about 8 degrees as the limit
