One method of hardware zooming is accomplished by multiplying the number of pixels and is known as pixel replication or simply, replication. Because replication increases the size of pixels and the effect is a blocky picture when zoomed, interpolation is a preferred technology where intermediate pixels are approximated causing less block video.
Industry:Software
The value of the saturation moment per unit weight of a magnetic material expressed in emu/gm. The specific magnetic moment is the most convenient quantity in which to express the saturation magnetization of fine particle materials.
Industry:Software
The relationship between scene luminances and the corresponding video signal. There may be several opto-electronic transfer functions for a single system, depending upon where in the progression of possible nonlinear processing, bandlimiting, etc., the video signal is being identified. When referred to the camera output before bandlimiting and processing, however, it is essentially a linear function.
Industry:Software
Computer software program which controls all functions of related computers and hardware devices.
Industry:Software
Data appearing in packets having PID code of zero that the MPEG decoder uses to determine which programs exist in a Transport Stream. PAT points to PMT (Program Map Table), which, in turn, points to the video, audio, and data content of each program.
Industry:Software
Any hardware device that requires a serial connection to communicate with the workstation.
Industry:Software
a) Reference in PS (Program Stream) for synchronizing the system demultiplex clock in the receiver, transmitted at least every 0.7 sec. Integrated into PES (Packetized Elementary Stream).
b) A time stamp in the program stream from which decoded timing is derived.
Industry:Software
A device used to combine video signals from two or more sources. Inputs are synchronized, then mixed along with various special effects patterns and shapes. A video mixer usually generates sync signals allowing genlocking of additional video sources to the first source. The Digital Video Mixer is capable of handling up to four video inputs.
Industry:Software
Adjusting the delay of a video signal to a reference video signal to ensure they are synchronous. This includes horizontal and subcarrier timing. Also called timing.
Industry:Software
A control which determines the output level of signals played back from the tape by the reproduce head.
