Video resolution and number of frames

1080i format with a resolution of 1920x1080i/60hz and a line frequency of 33.75kHz
720p format with a resolution of 1280x720p/60hz and a line frequency of 45kHz
480P format resolution is 720*480

The number of frames is the number of frames in a picture transmitted in 1 seconds, and it can be understood that the graphics processor can refresh several times per second, usually expressed as FPS (Frames per Second). Each frame is a stationary image, and a fast and continuous display of frames creates the illusion of motion. The high frame rate allows for smoother, more realistic animations. The greater the number of frames per second (fps), the smoother the displayed action will be.

Generally 30fps is acceptable, so the minimum FPS to avoid movement is 30. In addition to 30fps, some computer video formats, such as AVI, can only provide 15 frames per second. We are able to use the camera to see the continuous image, is because the image sensor constantly ingest the screen and transmission to the screens, when the transmission speed reached a certain level, the human eye can not distinguish between the time gap between the screen, so you will see the continuous dynamic picture.

Resolution: (Resalution) The total number of pixels that make up a single image, usually expressed by the number of horizontal pixels x vertical pixels. The higher the resolution, the clearer the image, but the smaller the resulting image or text. It is more closely related to the refresh rate. The higher the resolution when the refresh frequency is 85Hz, the better the performance of the display. The resolution can be divided into CGA,EGA,VGA,SVGA, etc., according to the number of horizontal and vertical pixels to differentiate, you can divide: 320x200,640x480,800x600,1024x768,1280x1024,1600x1280 and so on.
