What resolution is indicated by 720p?

The designation of 720p refers to a specific video resolution that is characterized by having 720 horizontal lines of vertical resolution displayed progressively. In this format, the image is transmitted as a full frame rather than subdividing the image into interlaced fields. This results in a clearer and more stable picture, especially during motion, compared to interlaced formats.

The key factor here is the '720 pixels,' which indicates the number of horizontal lines, and 'progressively' indicates that each frame is displayed in its entirety without interlacing. This makes 720p a popular format for many types of video content, providing a good balance between quality and bandwidth usage.

In summary, 720p is understood as a resolution where the display features 720 lines progressively scanned, thus ensuring better image quality for viewers.
