Functional Description
The CMOS device SDA 9290-6 is a picture processor and belongs to a family of devices
forming an extended third-generation digital TV signal-processing system for enhanced
picture quality with special functions (Featurebox). 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 Sequential-Access Memory devices (SDA 9251 X), a Memory
Sync Controller (MSC SDA 9220-5) and a Display Prozessor (SDA 9280). A block
diagram of the Featurebox is shown in figure 4.
The Picture Processor SDA 9290-6 is a follow-on development of the Picture Processor
SDA 9290-5. Modifications of the movement detector and the recursive filters permits
further picture improvement by reducing the video noise and cross-color interference.
The SDA 9290-6 can be set independently at the picture-signal input and output via the
two pins FSBQ/FSI to the 4:1:1 and 4:2:2 formats. A 4:1:1 Featurebox (3 TV-SAMs) can
therefore be operated with 4:2:2 input signals as well.
