A) A term pertaining to the bandwidth and spectrum position of the signal which results from television scanning and which is used to reproduce a picture. b) A complex and sophisticated electronic signal which, when properly processed by a television receiver can be used to provide full-color pictures. c) An electrical signal used to carry visual information.
Composite video includes sync and blanking signals. Non-composite video does not include sync.
Industry:Software
The interpretation of impressions transmitted from the retina to the brain in terms of information about a physical world displayed before the eye. Note: Visual perception involves any one or more of the following: recognition of the presence of something; identifying it; locating it in space; noting its relation to other things; identifying its movement, color, brightness, or form.
Industry:Software
The level corresponding to the specified maximum excursion of the luminance signal in the white direction. Refer to the Horizontal Timing discussion.
Industry:Software
The SPL of a sound is equal to twenty times the logarithm (base 10) of the ratio of the root-mean-square sound pressure to the reference sound pressure. As a point of reference, 0 dBSPL equals the threshold of hearing, while 140 dB-SPL produces irreparable hearing damage.
Industry:Software
Switch back and forth from one state or value to another (i.e., on, off, on, off, etc.) by alternately opening and closing an electric circuit.
Industry:Software
The Indeo video codec’s normal mode of operation, in which it takes as long as necessary to encode a video file so that it displays the best image quality and the lowest and most consistent data rate.
Industry:Software
The effect of signals being magnetically impressed on adjacent portions of tape. This is the effect of magnetic induction and its cause can be excessive spooling or heat. Factors affecting spurious printing are principally heat, tape thickness, and recording level and, to a lesser extent, time. Print-thru increases linearly with the logarithm of the time of contact, other factors being constant.
Industry:Software
A key effect in which a video signal serves as both the key source and fill.
Industry:Software
A) A synchronising bit pattern differentiated from the normal data bit patterns, used to identify reference points in the television signal; also to facilitate word framing in a serial receiver. b) A fixed pattern of bits inserted in a binary message for the purpose of synchronising the message interpreting unit.
