A video signal generator is a type of signal generator which outputs predetermined video and/or television oscillation waveforms, and other signals used in the synchronization of television devices and to stimulate faults in, or aid in parametric measurements of, television and video systems. There are several different types of video signal generators in widespread use. Regardless of the specific type, the output of a video generator will generally contain synchronization signals appropriate for television, including horizontal and vertical sync pulses (in analog) or sync words (in digital). Generators of composite video signals (such as NTSC and PAL) will also include a colorburst signal as part of the output.
Video signal generator supporting multi-protocol output and programmable timing
PendingCN122179521ATelevision system detailsColor television detailsVideo-signal generatorComputer architecture
The application discloses a video signal generator supporting multiple protocol outputs and timing programming, comprising a power module, a clock module, an optical fiber data receiving module, a cache management module and a multiple protocol video and timing generation module. The application takes a field programmable logic gate array as a core architecture, solves the problems of single protocol and non-self-defined video timing of a traditional video signal generator, has the ability of multiple channel independent and synchronous output and non-standard timing video generation, and can provide required signal sources for development and test of various video display devices.
