Hi there! It’s high time that we should give you some insights into our latest improvements and the direction of further efforts.
First of all, we would like to let you know our main goal is to improve your viewing experience substantially via a large screen and high resolution when you have a compressed DVD at your disposal and even regular movies at hand in hope of watching them at a higher resolution. Fortunately, all your expectations and desirable needs can be met now in view of our constant innovations and improvements. Thus, we are glad to share with you the challenges we have tackled from multiaspects.
Essential Details about DVD Formats
Usually, DVDs include two formats, namely, PAL (720×576) and NTSC (720×480), whose aspect ratios are respectively 16:9 and 4:3. As you may know, the data stored on a DVD is not the motion picture (that occupies a huge storage space) filmed originally, but a lossy compressed version of the original content. For a DVD, its encoding algorithm is called MPEG, a lossy compression algorithm similar to JPEG for pictures, both using the DCT algorithm on 8×8 pixel blocks. As for motion pictures, the quality of their frames remains arguably decent when viewed on a small screen, but when resized on a large screen of a modern TV, the viewing experience will be undermined at once due to the cubic artifacts of the image (blocky aspect), along with the loss of color and details.
