Before the opening of the article, let's take a look at the development of audio and video. From VCD, DVD to BD, we have experienced almost 20 years of time. In the elementary school of Xiaobian, it was through the years of VCD. At that time, there was a VCD machine at home, but Yaowu Yangwei The excellent weapon, now look back, VCD and DVD are only in the memory of yellowing, and the development of the late BD player can be described as “interestingâ€, and it has been entangled with DVD for 6 years. Win, but because of the storage media (a Blu-ray movie is at least 25GB in size, typically around 50GB and 100GB, needs to be stored on a BD disc, hard disk, etc.) and display device (at least 1080P) can not keep up with the Blu-ray standard and lose Market. With the rapid development of the Internet in recent years, the new ultra-high definition Blu-ray standard began to fully explode in 2016. Compared with Blu-ray, it has a congenital advantage of ultra-high-definition display devices, including TVs and projectors, which have been introduced to the market almost at the same time. The rapid development of the Internet has also opened up the territory for ultra-high-definition streaming media video content, and the rest is the decoding core of Ultra HD players and the introduction of finished products to the market. Now the new 4K set-top box or hard disk player, without exception, are equipped with ultra-high-definition Blu-ray processor, can decode ultra-high-definition Blu-ray video files through hardware to bring a more smooth decoding and output experience. There are many experienced enthusiasts who may think that "soft solution quality is better than hard solutions." This is true when the hardware is not yet mature, but with the development of hardware technology, advanced hardware decoding can handle image operations. Depth is not worse than software, and even better than software decoding, and does not take up system resources, resulting in a good decoding performance and outstanding performance. The ultra-high definition Blu-ray standard has 5 aspects, including 4K resolution, 10Bit-12Bit high color depth, HDR high dynamic, 60P high frame count, BT.2020 high color gamut space, thus bringing more picture dynamics and color space. Richer picture details are presented. So what are the decoding chips that support Ultra HD Blu-ray? Who is the Lord? The ultra-high definition Blu-ray standard emerged in 2016 and has been widely developed. In 2017, many camps have formed, and many product series have been formed for market selection. Diversified products promote healthy competition in the market, and therefore, there is now The ultra-high-definition Blu-ray video market is blooming. At present, the mainstream ultra-high-definition decoding chips on the market are represented by HiSilicon Hi3798CV200, the United States Crystal Chen S912, and Raychem RTD1295, which bear the general trend of ultra-high-definition Blu-ray in the market.
