A single chip multistandard video encoder

A single-chip multistandard encoder (MSE) has been developed for multimedia and computer applications. The MSE is a highly integrated mixed signal CMOS IC which serves as a color encoder and a graphic DAC at the same time. All processing steps are carried out digitally, making any filter or color adjustment obsolete. It delivers an analog composite video signal and an S-VHS signal (chroma and luma separated) which can be fed directly into a 75 Omega video input (e.g. SCART) of a connected device. In addition, it includes three digital-to-analog converters (DACs) for the digital input signals which also can directly drive 75 Omega loads. The composite signals can be coded as PAL, NTSC (National Television System Committee), or SECAM or, in a special mode, a NTSC with 4.43 MHz color subcarrier frequency. The chip requires a digital component input signal that is 3-b*8-b RGB (red, green, blue) (true color) or YUV format.<
