1080p is the shorthand identification for a set of high-definition television (HDTV) video modes that are characterised by 1080 horizontal lines of vertical resolution and progressive scan, meaning unlike the 1080i display standard, the image is not interlaced.
The term usually assumes a widescreen aspect ratio of 16:9, implying a resolution of 1920 pixels wide by 1080 high. This resolution is similar to that of 2K digital cinema technology. The frame rate can be either implied by the context or specified after the letter ‘p’, such as 1080p30, meaning 30 progressive frames per second.
1080p, sometimes referred to in marketing materials as Full HD, typically refers to the capability to accept 1080p signal and display it with native resolution of at least 1080 lines, as well as the capability to upscale lower-resolution material to 1080p.
HD ready 1080p logo program by DIGITALEUROPE requires that certified TV sets support 1080p24, 1080p50, and 1080p60 formats, and feature a native resolution of at least 1920×1080 pixels, among other requirements.
