Analysis of Blu-ray Players and Their Development Advantages and Obstacles
On the Blu-ray player and its advantages and obstacles to the development of the current DVD <br> scenery is gone, after completing its historic task, DVD because no longer meet the requirements of large-size display device, therefore, the development of the times makes it more A product with excellent playback effects fills this gap, so the Blu-ray player is one of them.
The reason why we want to say goodbye to the DVD, and vigorously advocate the era of Blu-ray, is not just a kind of propaganda of the manufacturers, but because the Blu-ray player does have the advantage that DVD can't match. Even in terms of playback effects, it is also ahead of HD player or HTPC playback. After all, many HD videos are extracted from Blu-ray discs, and the current HD sources are reduced on the basis of Blu-ray, such as audio tracks. Etc. is reduced relative to Blu-ray Disc.
Blue ray stands for Blu-ray technology and does not represent better film quality or audio. Most 1080p videos on the Internet are generally damaged for easy downloading and storage. Blu-ray movies are not compressed and produced without damage.
The Blu-ray player can realize 1080p HD format output with 1920×1080 resolution through Blu-ray Disc movie through Blu-ray Disc. 1080P is also the highest specification currently on the market. We often say that Blu-ray playback is six times higher than traditional DVDs. It just means that it can support 1080P at 6 times the resolution of traditional DVDs. That is 1080P (1920*1080) is the current 5 times resolution of DVD video (PAL 720*576), 6 times resolution (NTSC 720*480).
In addition to the normal DVD, in addition to Blu-ray to provide high-definition video also provides high-definition audio, can provide up to 7.1-channel DTS-HD sound quality, which is unmatched by the high-compression audio of DTS5.1 in the DVD era. The Blu-ray player also brings a revolution in audio enhancement.
For the network, the Blu-ray player has also been greatly improved, such as the BD-live function, which allows customers to download some movie news, trailers and even games for better use.
It can be seen that the Blu-ray playback effect is theoretically far superior to that of DVDs, which makes it even more apparent on large-size TVs or other display devices. At present, most large-screen LCD TVs require a Blu-ray player. If you buy a TV with a size of 40 inches or more, you can only see the normal effect, and lose the large screen and high resolution of the LCD TV. The effect of the rate is also relatively reduced in the use of the television. So if the DVD replaces the VCD, it is now when the Blu-ray player replaces the DVD. Therefore, the development of the Blu-ray player has been popular among manufacturers, but the Blu-ray player has not expected the same effect as the DVD market in the past. The reason is the result of many factors. Let's take a look at the king in HD and see how much Blu-ray you know.
