Video Resolutions:

• PAL & NTSC
  • NTSC, named for the National Television System(s) Committee, is the analog television system that is/was used in most of the Americas, Japan, South Korea, Taiwan, Burma, and some Pacific island nations and territories. NTSC color encoding consists of 29.97 interlaced frames of video per second. Each frame consists of a total of 525 scanlines (486 are visible). The remainder are used for synchronization and retrace. Originally designed to be blank, some of these lines now can contain other data such as closed captioning.
    The complete raster has the even-numbered or 'lower" scanlines (lines 21 to 263 in the video signal) are drawn in the first field, and the odd-numbered or "upper" (signal lines 283 to 525) are drawn in the second field, to yield a flicker-free image at the field refresh frequency of approximately 59.94 Hertz (actually 60 Hz/1.001). For comparison, 576i systems such as PAL-B/G and SECAM uses 625 lines (576 visible), and so have a higher vertical resolution, but a lower temporal resolution of 25 frames or 50 fields per second
  • PAL, short for Phase Alternating Line, is an analogue television encoding system used in broadcast television systems in large parts of the world. Another common analogue television system is SECAM. For the most part Pal uses a 625-line / 25 frame per second television standard. Although there other variations.

• SDTV: 480i (NTSC uses an analog system of 486i split into two interlaced fields of 243 lines)
• SDTV: 576i (PAL, 720×576 split into two interlaced fields of 288 lines)
• EDTV: 480p (720×480 progressive scan)
• EDTV: 576p (720×576 progressive scan)
• HDTV: 720p (1280×720 progressive scan)
• HDTV: 1080i (1920×1080 split into two interlaced fields of 540 lines)
• HDTV: 1080p (1920×1080 progressive scan)

Media Types:

• VHS or Video Home System is a video tape recording standard developed during the 1970s. A VHS cassette holds a maximum of about 430 m of tape at the lowest acceptable tape thickness, giving a maximum playing time of about 3.5 hours for NTSC and 5 hours for PAL at "standard" (SP) quality. Another VHS type is VHS-Compact (VHS-C), originally developed for portable VCRs but ultimately finding success in palm-sized camcorders.
• Mini DV is more commonly referred to as just DV tape. The "L" cassette can record up to 4.6 hours of video (6.9 hours in EP/LP). The better known MiniDV "S" cassettes, 65 × 48 × 12 mm and hold either 60 or 90 minutes of video (13 or 19.5 GB[citation needed]) depending on whether the video is recorded at Standard Play (SP) or Extended Play (sometimes called Long Play) (EP/LP). 80 minute tapes that use thinner tape are also available and can record 120 minutes of video in EP/LP mode. The tapes sell for as little as US$2.50 each in quantity as of 2009. DV on SP has a helical scan track width of 10 micrometres, while EP uses a track width of only 6.7 micrometres. Since the tolerances are much tighter, the recorded tape may not play back properly or at all on other devices.
• DVD, also known as Digital Versatile Disc or Digital Video Disc, is an optical disc storage media format, and was founded in 1995.Dual-layer recording (sometimes also known as double-layer recording) allows DVD-R and DVD+R discs to store significantly more data up to 8.54 gigabytes per disc, compared with 4.7 gigabytes for single-layer discs. Along with this, DVD-DL's have slower write speeds as compared to ordinary DVD's and when played on a DVD player, a slight transition can be seen between the layers.
• Blu-ray Disc (also known as Blu-ray or BD) is designed to supersede the standard DVD format. Its main uses are for storing high-definition video, PlayStation 3 games, and other data, with up to 25 GB per single layered, and 50 GB per dual layered disc. The disc has the same physical dimensions as standard DVDs and CDs. The name Blu-ray Disc derives from the blue-violet laser used to read the disc. While a standard DVD uses a 650 nanometre red laser, Blu-ray uses a shorter wavelength, a 405 nm blue-violet laser, and allows for almost six times more data storage than a DVD.
