Besides the Picture Processor (PP) that is described here, the system consists of a field memory (at least three triple-port, 1-Mbit generation TV SequentialAccess Memory devices (SDA 9251 X), a Memory Sync Controller (MSC SDA 9220-5) and a Video D/A converter (SDA 9094-5). A block diagram of the Featurebox is shown in figure 1. The Picture Processor SDA 9290-5 is a follow-on development of the Picture Processor SDA 9090 from the second-generation Featurebox and permits further picture improvement by reducing the video noise and cross-color interference. The SDA 9290-5 can be set independently at the picturesign...
