Full HD is high definition video. Apply it to broadcasts with HDTV resolution.
The resolution of Full HD video systems is 1280x720 and1920x1080 pixels, the sides are 16: 9. In a video with standard definition (SD), the aspect ratio is 4: 3. High clarity is achieved by increasing the image detail by five times. Standard image clarity - individual points 720x576 = 414720. The number of points for the HD720 format increases to 1280x720 = 921600, and for the HD1080 - 1920x1080 = 2073600, or two megapixels. This is n times the standard definition. Most manufacturers are not very competent in the question of what is Full HD. They talk about 6 megapixels on TVs. It is not entirely correct, it is more accurate to say that there are 6 million subpixels. After all, each color pixel has three subpixels with basic colors, such as:
• red;
• green;
• blue.
Interlaced scanning supports frames with the following frequencies: 25, 29.97, 30 in one second.
Progressive scan manages frames 50, 59.94, 60.
Thus, movies in HD - 24 frames per second.
Обозначение HD720/24p расшифровывается как кадр The resolution is 1280x720 pixels, because of the progressive scanning of 24 frames per second HD 1080 / 29.97i - the frame is 1920x1080, thanks to the interlaced scanning - 29.97 frames.
Just do not confuse the frame rate with a scan of 100Hz on TVs. At higher sweep frequencies, the same frames are shown several times. In the movie, to reduce flicker, each frame is shown twice (48 Hz), and 24 different frames in just a second.
Statistics, statistics, and that is Full HD, you need to make sure on their own experience.
On panels with Full HD support with a high-quality signal source, high definition video is very obvious.
How is it achieved?
1. Detailing the picture is improved five times. It is provided with a large number of points that make up the image.
2. The frame contains more information. Small parts do not merge into a solid background.
3. The texture of materials is better developed.Grass, fur, frost patterns have become more clear. The final image is more realistic. Now you know what Full HD is. This support for high-definition video of all formats, up to the maximum - 1920x1080. If the matrix that is included in the TV or panel comes with a resolution of 1280, 1336, 1440, then there can be no talk about Full HD. Such a maximum matrix allows you to display HD720 - is HD-Ready.
The differences between HD-Ready and Full HD are as follows:
one.There is no guarantee that a TV without a label with a matrix of 1280 pixels in width will clearly show. Such a device, rather, displays the SD-signals. It interpolates the standard clear “up” signal, increasing the base resolution SD to the physical resolution of the matrix.
2. Marking HD-Ready allows you to view standard and high definition video.
3. Full-HD allows you to display SD, HD, HD 1080.Typically, these TVs are equipped with more powerful video processors, which allows you to watch HD movies in high quality directly at home. Manufacturers are trying to equip Full HD-TVs best matrices, so they have the highest price range.
Based on all the above, you can answer the question of what is Full HD. This is really a high-quality image that is always a pleasure to watch!
