Video formats Video formats 1080i is the shorthand name for a category of video modes. The number 1080 stands for 1080 lines of vertical resolution, while the letter i stands for interlaced or non- progressive scan. 1080i is considered to be an HDTV video mode. The term usually assumes a widescreen aspect ratio of 16:9, implying a horizontal resolution of 1920 lines and a frame resolution of 1920 × 1080 or about 2.07 million pixels, and a field resolution of 1920 × 1080 / 2 (because it's interlaced) or about 1.04 million pixels. The field rate (not the frame rate) in hertz can be either implied by the context or specified after the letter i. The two field rates in common use are 50 and 60 Hz, with the former (1080i50) generally being used in traditional PAL and SÉCAM countries (Europe, Australia, much of Asia, Africa, and South America), the latter (1080i60) in traditional NTSC countries (North America, Japan). Both variants can be transported by both major digital television formats, ATSC and DVB. ...more on Wikipedia about "1080i"
1080p is the shorthand name for a category of video modes. The number 1080 stands for 1080 lines of vertical resolution, while the letter p stands for progressive scan or non- interlaced. 1080p is considered to be an HDTV video mode. The term usually assumes a widescreen aspect ratio of 16:9, implying a horizontal resolution of 1920 lines and a frame resolution of 1920 x 1080 or about 2.07 million pixels. The frame rate in hertz can be either implied by the context or specified after the letter p (such as 1080p30, meaning 30 frames per second). ...more on Wikipedia about "1080p"
24p is a video format which runs twenty-four progressive (hence the "P") frames per second, essentially the same as film does. Originally used for utilitarian purposes in non-linear editing, today the format is widely used for aesthetic reasons by both high-end professional and independent media makers. In particular, 24P HD already provides a reasonably viable alternative to the film format and may replace it altogether in the future. ...more on Wikipedia about "24p"
480i is the shorthand name for a video mode. The i stands for interlaced, the 480 for a vertical resolution of 480 lines, usually with a horizontal resolution of 640 pixels and an aspect ratio of 4:3; that is standard-definition television (SDTV). The field rate (not the frame rate) is usually 60 hertz and can be given explicitly after the letter (480i60. It is usually used in former NTSC countries (North America, Japan) for NTSC is exactly that resolution, but analogue. It can be transported by both major digital television formats, ATSC and DVB, and on DVD. ...more on Wikipedia about "480i"
480p is the shorthand name for a video mode. The p stands for progressive scan, i.e. non-interlaced, the 480 for a vertical resolution of 480 lines, usually with a horizontal resolution of 640 pixels and an aspect ratio of 4:3; that is standard-definition television (SDTV). The frame rate (in the interlaced case the field rate) is usually 30 or 60 hertz and can be given explicitly after the letter. It is usually used in former NTSC countries (North America, Japan) for NTSC can have 480p30 image resolution, but analogue and interlaced. With doubled temporal resolution, 480p60 is considered enhanced-definition television ( EDTV). It can be transported by both major digital television formats, ATSC and DVB, 480p30 also on DVD. ...more on Wikipedia about "480p"
576i is the shorthand name for a video mode. The i stands for interlaced, the 576 for a vertical resolution of 576 lines, usually with a horizontal resolution of 720 pixels and an aspect ration of 4:3; that is standard-definition television (SDTV). The field rate (not the frame rate) is usually 50 hertz and can be given explicitly after the letter (576i50). It is usually used in former PAL and SÉCAM countries for these are exactly that resolution, but analogue. It can be transported by both major digital television formats, ATSC and DVB, and on DVD. ...more on Wikipedia about "576i"
576p is the shorthand name for a video mode. The p stands for progressive scan, i.e. non-interlaced, the 576 for a vertical resolution of 576 lines, usually with a horizontal resolution of 720 pixels and an aspect ratio of 4:3; that is standard-definition television (SDTV). The frame rate (in this case equal to the field rate) is usually 25 or 50 hertz and can be given explicitly after the letter. It is usually used in former PAL or SECAM countries for these can be 576p25, but analogue. With doubled temporal resolution, 576p50 is considered enhanced-definition television ( EDTV). It can be transported by both major digital television formats, ATSC and DVB, 576p25 also on DVD. ...more on Wikipedia about "576p"

720p is the shorthand name for a category of video modes. The number 720 stands for 720 lines of vertical resolution, while the letter p stands for progressive scan or non- interlaced. 720p is considered to be an HDTV video mode. The term usually assumes a widescreen aspect ratio of 16:9, implying a horizontal resolution of 1280 lines and a frame resolution of 1280 x 720 or about 0.92 million pixels. The frame rate (in this case equal to the field rate) can be either implied by the context or specified in hertz after the letter p. The five 720p frame rates in common use are 24, 25, 30, 50 and 60 Hz. In general, traditional PAL and SÉCAM countries (Europe, Australia, much of Asia, Africa, and South America) are or will be using 720p25 and 720p50, whereas traditional NTSC countries (North America, Japan) are using 720p24 (for movies), 720p30, and 720p60. All variants can be transported by both major digital television formats, ATSC and DVB. ...more on Wikipedia about "720p"

PALplus is an extension of the PAL analogue broadcasting system for transmitting 16:9 programs with improved vertical resolution. A standard PAL receiver will display the image in letterbox format with 432 active lines, while a PALplus receiver can use extra information hidden in the black bars above and below the image to recreate 576 lines of vertical resolution. ...more on Wikipedia about "PALplus"
