Digital Video Recorder - File Formats, Resolutions and File Systems

File Formats, Resolutions and File Systems

DVRs can usually record and play H.264, MPEG-4 Part 2, MPEG-2 .mpg, MPEG-2 .TS, VOB and ISO images video, with MP3 and AC3 audio tracks. They can also display images (JPEG and PNG) and play music files (MP3 and Ogg).

Some devices can be updated to play and record in new formats.

Recordings from standard-definition television usually have 480p/i/576p/i while HDTV is usually in 720p/1080i.

DVRs usually record in proprietary file systems for copy protection, although some can use FAT file systems.

Famous quotes containing the words file, resolutions and/or systems:

    While waiting to get married, several forms of employment were acceptable. Teaching kindergarten was for those girls who stayed in school four years. The rest were secretaries, typists, file clerks, or receptionists in insurance firms or banks, preferably those owned or run by the family, but respectable enough if the boss was an upstanding Christian member of the community.
    Barbara Howar (b. 1934)

    No woman ever yet either reasoned or acted long together consequentially; but some little thing, some love, some resentment, some present momentary interest, some supposed slight, or some humour, always breaks in upon, and oversets their most prudent resolutions and schemes.
    Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)

    Our little systems have their day;
    They have their day and cease to be:
    They are but broken lights of thee,
    And thou, O Lord, art more than they.
    Alfred Tennyson (1809–1892)
