| 480p | A Standard Definition video format consisting of 480 vertical lines of display resolution in a Progressive scan, usually with a horizontal resolution of 640 pixels and 4:3 aspect ratio. The frame rate (hertz) is usually 30 or 60 progressive frames per second. |
| 576p | A Standard Definition video format consisting of 576 vertical lines of display resolution in a Progressive scan, usually with a horizontal resolution of 720 or 704 pixels. The frame rate can be given explicitly after the letter. |
| 720p | A High Definition video format consisting of 720 vertical lines of display resolution in a Progressive scan. When broadcast at 60 frames per second, 720p features the highest temporal (motion) resolution possible under the ATSC and DVB standards. Progressive scanning reduces the need to prevent flicker by filtering out fine details, so sharpness is much closer to 1080i than the number of scan lines would suggest. |
| 1080p | A High Definition video format consisting of 1,080 vertical lines of display resolution in a Progressive scan, meaning the image is not interlaced. Only 1080p can be referred to as full HD or full high definition although 1080i (interlaced) is also 1920x1080 pixels. |
| PAL | PAL (Phase Alternation Line) is the analog television display standard that is used in Europe and certain other parts of the world. The term PAL is often used informally to refer to a 625-line/50 Hz (576i), television system, and to differentiate from a 525-line/60 Hz (480i) NTSC system |
| PAL B/G/D/K/I | The majority of countries using PAL have television standards with 625 lines and 25 frames per second, differences concern the audio carrier frequency and channel bandwidths. Standards B/G are used in most of Western Europe, standard I in the UK, Ireland, Hong Kong and Macau, standards D/K in most of Central and Eastern Europe and Standard D in mainland China. Most analogue CCTV cameras are Standard D. |
| PAL-M | In Brazil, PAL is used in conjunction with the 525 line, 29.97 frame/s system M, using (very nearly) the NTSC colour subcarrier frequency. Exact colour subcarrier frequency of PAL-M is 3.575611 MHz. |
| PAL-N | In Paraguay and Uruguay, PAL is used with the standard 625 line/50 fields per second system, but again with (very nearly) the NTSC subcarrier frequency. People in Uruguay, Argentina and Paraguay usually own TV sets that also display NTSC-M, in addition to PAL-N. |
| PAL-Nc | In Argentina, the PAL-Nc (combination N) variant is used. It employs the 625 line/50 field per second waveform of PAL-B/G, D/K, H, I, but with a chrominance subcarrier frequency of 3.582 MHz. |
