MOD can be a computer extendable used primarily to represent music, the first module file format. MOD files make use of the “.MOD” file extension, except on the Amiga the spot that the original trackers instead use a “mod.” prefix scheme, e.g. “mod.echoing”. A MOD file boasts a group of instruments available as samples, a number of patterns indicating how when the samples should be played. Standard definition (SD) video is saved in MPEG program stream container files with MOD extension; practically in most others these files have extension MPG or MPEG. Hi-def (HD) video is kept in MPEG transport stream container files with TOD extension; generally in most others these files have M2T extension.

 

MOD video can be seen on a computer using a player that is certainly competent at reproducing MPEG-2 video. This video can be easily authored for watching on a DVD player, like WinX DVD Player, without recompression, as it would be fully compliant with DVD-video standard. And TOD format is comparable with AVCHD, but is not directly played on consumer video equipment. Media files have to be packaged into distribution formats like HD DVD or Blu-ray Disc, using authoring software. MOD and TOD are informal names of tapeless video formats as used by JVC (TOD and MOD), Panasonic (MOD only) and Canon (MOD only) in some types of digital camcorders. Format names correspond to extensions of video files. Neither JVC nor Panasonic, who pioneered the format, explained specification of the file extensions, and the formats were never given the state run name. MOD is utilized exclusively for standard definition video files, while TOD can be used for hd files. Both MOD and TOD are file-based formats that are stored over a random-access media.

 

JVC was the sole supporter of TOD format. In 2008 JVC released several hybrid TOD/AVCHD consumer models, and several AVCHD only models. Consumer hi-d camcorders offered by JVC since 2009 record only in AVCHD format. Professional JVC tapeless camcorders, introduced last year, use XDCAM EX format, licensed from Sony. Like TOD, XDCAM EX employs MPEG-2 HD codec. Unlike TOD, XDCAM EX is widespread in professional video. By 2009, MOD format is still being utilized in standard definition camcorders manufactured by JVC, Canon and Panasonic.
