Industry:Software
A term used to describe a device used to convert film to video.
In advanced telecine machines, the movie film is digitally sampled and converted to video, frame by frame in real-time. Frame rate is the biggest problem encountered in film-to-video conversion. Movie film has a frame rate of 18, 24, or 30 fps (frames per second) contrasting with the 30 and 25 fps video frame rates of NTSC and PAL respectively. See Flicker.
Industry:Software
The shape of an electro-magnetic wave. A graphical representation of the relationship between voltage or current and time.
Industry:Software
The value assigned to an alternating current or voltage that results in the same power dissipation in a given resistance as DC current or voltage of the same numerical value. Calculated as 0.707 of peak amplitude of a sine wave at a given frequency.
Industry:Software
A flickering of fine horizontal edges caused by interlaced scanning.
A fine line appearing in only one field is presented below the flicker frequency; therefore, it flickers. Twitter is eliminated in line doubling schemes that change from interlaced to progressive scanning, as most of the IDTV schemes do. Interestingly, twitter was much less of a problem in the early days of NTSC, than it is today, because early cameras and displays didn’t have sufficient detail to confine an edge to one scanning line.
Industry:Software
A term used in two contexts: in programme streams, a packet is a unit that contains one or more presentation units; in transport streams, a packet is a small, fixed size data quantum.
Industry:Software
A variable-rate search, forward or reverse, of a videotape using a video deck or VCR capable of such an operation.
