1080p is the shorthand identification for a set of HDTV video modes that are characterised by 1,080 lines of vertical resolution (1,080 horizontal scan lines)[1] and progressive scan(meaning the image is not interlaced, unlike the 1080i display standard).
The term usually assumes a widescreen aspect ratio of 16:9, implying a horizontal resolution of 1920 pixels. 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.
Blu-ray Disc
Blu-ray Discs are able to hold 1080p HD content, and most movies released on Blu-ray Disc produce a full 1080p HD picture when the player is connected to a 1080p HDTV with anHDMI cable. However, the Blu-ray Disc video specification only allows encoding of 1080p24 signal, and not 1080p50 or 1080p60.[12]
