Entries found for search: frame

frame lock : Frame lock maintains synchronization between master and slave transports, using the positional information available in the timecode address. Also called frame sync. See SMPTE timecode.

feet/frames : Footage numbers for film, either separated by a colon or by a "plus" sign. For example, 101:16 and 0101+16 both indicate a point 101 feet and 16 frames into the film. There are 16 frames per foot of 35mm film, and 40 frames per foot of 16mm film. See SMPTE timecode, LFOP, ABS.

frame : (1) The internal structural support of a loudspeaker when holds the voice coil and the diaphragm. (21) The basic unit of SMPTE timecodetime code, corresponding to one frame of a film or video image. Depending on the format used, SMPTE time can be defined with 24, 25 30 or 29.97 frames per second (fps). (32) In digital audio, a frame is a unit of digital information. In the CD, a frame covers six sampling periods, or 136Ás.

frame rate : See frame.

subframe : In SMPTE timecode synchronization, a unit of time smaller than a frame, generally 1/100th of a frame in length. Synchronizers are designed to maintain synchronization to within a small number of subframes. See frame sync, phase sync.

zero frame : The first frame of a roll of film or video tape, appropriately numbered 00:00:00:00.

drop-frame timecode time code: A version of the SMPTE timecode used for color video recording where two frames are dropped at the beginning of each minute, except at the beginning of every tenth minute, devised to compensate for the difference between the NTSC (US) standard of 29.97fps and a real-time counter. The difference equates to 108 frames per hour. To avoid this confusion, most audio-only synchronization applications specify a non-drop timecodetime code.

Frame Relay : An interface specification based on ISDN data link layer protocol.
