Digital video frames are generally defined as a grid of pixels used to present each sequential image. The horizontal component is defined by pixels (or samples), and is known as a video line. The vertical component is defined by the number of lines, as in 480 lines.
Video is encoded with the AVC/H.264 compression scheme. Audio is encoded with the AAC codec. The compressed audio and video are multiplexed into a QuickTime file. To reduce data rate and hardware requirements, video frame has size of 960 horizontal by 540 vertical pixels with pixel aspect ratio of 1:1, which results in 16:9 display aspect ratio.

Since analog transmission of video is scan line-based, the same number of horizontal lines is always transmitted. However, several factors impede the ability to display fine detail within a line: The camera or other source of material. The storage and processing of the picture. The transmission of the TV signal e.g. broadcast by radio or by cable.
