At present, most mobile DVDs on the market adopt a foldable design, which looks similar to a thin and light notebook computer. The biggest advantage of the foldable mobile DVD is that it is relatively portable, and the volume is relatively small after being folded, which can be easily carried on the road, such as on a car or on a business trip.
Compared with ordinary DVD, in addition to providing high-definition video in Blu-ray, it also provides high-definition audio, which 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. For the network, Blu-ray players have 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 through the network.

Full area decoding
The world is currently divided into six regions, and the DVD discs circulating in each region must be set with a movie region code. For example: DVD discs encoded in the US (Region 1) cannot be played on players sold in China (Region 6). Full-region decoding can play DVD discs in any region for playback.
4K extremely clear
It can support 4K resolution, that is, a pixel resolution of 3840 × 2160, which belongs to ultra high definition resolution. At this resolution, the viewer will be able to see every detail and every feature in the picture.
The abbreviation of high-definition multimedia interface is a digital video / audio interface technology that can simultaneously transmit video and audio signals without the need for digital / analog or analog / digital conversion before signal transmission. It can also support digital audio formats such as DVD Audio, eight-channel 96kHz or stereo 192kHz digital audio transmission, and can transmit uncompressed audio and video signals.
Using polarized 3D technology with non-flashing 3D glasses, the two eyes can see the corresponding parallax picture to form stereo vision; the viewing angle is wide, and you can enjoy 3D images with light and comfortable glasses.
The 3D effect can be achieved by increasing the refresh rate of the picture, which can maintain the original resolution of the picture. When used with active shutter 3D glasses, its 3D glasses are more expensive than polarized 3D.
The power-off memory function means that when the point source switch is turned off when playing a regular DVD disc, the machine can automatically recognize the time point when the power is turned off and start playback when the power switch is restarted.
The display is usually divided into two scanning modes: progressive scanning and progressive scanning. Compared to interlaced scanning, progressive scanning is an advanced scanning method. It means that when the image displayed on the display screen is scanned, the scanning starts from the first line in the upper left corner of the screen and the entire image scanning is completed at one time. Therefore, the image display screen flickers small, and the display effect is good. Most advanced displays currently use progressive scanning.
The most precise part of the DVD, commonly known as the "bare head", is the core component of a VCD or optical drive , and is mainly responsible for reading data. DVD discs are composed of two upper and lower film bases, each of which can accommodate up to two layers of data. The DVD optical head can read the two layers of data by adjusting the focal length.
