EM9010
EM9010 is Advanced Multimedia Analog Overlay Chip manufactured by Sigma Designs.
Advanced Multimedia Analog Overlay Chip
Description
The EM9010 is an advanced multimedia analog overlay chip that provides overlaying live video over VGA graphics. It is the ideal panion chip for applications displaying (full-screen or in a window) high-quality video, such as Progressive DVD. Analog overlay technology eliminates the need for the traditional feature connector on the VGA video card. This eliminates patibility problems with different VGA feature connector standards and allows users to upgrade their graphics controller card without worrying about patibility issues. The EM9010 accepts both digital and analog inputs for MPEG video. Included on-chip are a YCb Cr to RGB color space converter, triple 8-bit video DACs, automatic polarity detection of the VGA HSYNC and VSYNC signals, and an integrated timing generator to generate PAL/NTSC timing signals.
