Full HD is a high resolution video. It is used for broadcasts with HDTV resolution.
The resolution of Full HD video systems is 1280x720 and 1920x1080 pixels, the sides are 16: 9. In standard definition (SD) video, the aspect ratio is 4: 3. High definition is achieved by increasing the detail of the picture by five times. Standard image clarity - individual pixels 720x576 = 414720. The number of pixels for the HD720 format rises 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 on what Full HD is. They talk about 6 megapixels on TVs. This is not entirely correct, it is more accurate to claim that there are 6 million subpixels. After all, each color pixel has three subpixels with basic colors, such as:
• red;
• green;
• blue.
Interlacing supports frames with the following frequencies: 25, 29.97, 30 in one second.
Progressive scan controls frames 50, 59.94, 60.
Thus, films in HD - 24 frames per second.
The designation HD720 / 24p stands for 1280 × 720 resolution frame, due to progressive 24 frames per second HD 1080 / 29.97i - 1920 × 1080 frame, thanks to interlaced scanning - 29.97 frames.
Just do not confuse the frame rate with a scan of 100 Hz on TVs. At higher scan frequencies, the same frames are displayed 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 what Full HD is, you need to see for yourself.
On panels that support Full HD with a high-quality signal source, high definition video is very obvious.
How is it achieved?
1. Detailing of the picture is improved five times. It is provided by a large number of points that make up the image.
2. The frame contains more information. Small details do not merge into a continuous background.
3. The texture of the materials is better developed. Grass, fur, frost patterns have become clearer. The resulting image is more realistic. Now you know what Full HD is. This is support for high-definition video in all formats, up to a maximum of 1920x1080. If the matrix, which is part of the TV or panel, comes with a resolution of 1280, 1336, 1440, then there can be no talk about Full HD. Such matrices allow you to display the HD720 at most - it's HD-Ready.
The differences between HD-Ready and Full HD are as follows:
1. There is no guarantee that an unmarked TV with a matrix of 1280 pixels wide will clearly show. Such a device, rather, displays SD signals. It interpolates the standard clear signal "up", increasing the basic resolution of SD to the physical resolution of the matrix.
2. HD-Ready marking allows you to view standard and high definition video.
3. Full-HD allows you to display SD, HD, HD 1080. Typically, such 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 with the best matrices, so they have the highest price range.
Based on the foregoing, we can answer the question of what Full HD is. This is a really high-quality image, which is always nice to watch!
