Order this document from Analog Marketing Product Preview Picture-in-Picture (PIP) Controller The MC44463 Picture–In–Picture (PIP) controller is a low cost member of a family of high performance PIP controllers and video processors for television. It is a follow–up to the MC44461 PIP, in which two additional modes of operation have been added. A replay mode is provided, which captures several seconds of the main picture for replay in four different speeds. The capture time is programmable in four resolutions (ratio of captured fields to total fields), which trade the number of fields captured to the length of replay time. The second additional mode provides for multiple small picture overlays from a second non–synchronized source. The number of PIP images is 3 for the 1/9 screen area and 4 for the 1/16 screen area. Like the MC44461 this is NTSC compatible, I2C bus controlled and available in the 56–pin shrink dip (SDIP) package.
