The display part converts the digital YCrCb to analog RGB (see Fig. 27) and provides contrast and saturation
adjustment. In case of YCrCb 4:1:1 an interpolation filter is used, which converts the digital input signal to YCrCb 4:2:2 standard. The 4:2:2 YCrCb signal is processed by the horizontal scaler. In the luminance processing path, a variety of features, such as Ndynamic peaking and soft limiting, are provided. In the chrominance path, the CrCb signals are converted to 4:4:4 format and filtered by a color transient improvement circuit. The YCrCb signal is converted by a programmable matrix to RGB color space.

Stresses beyond those listed in the "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only. Functional operation of the device at these or any other conditions beyond those indicated in the "Recommended Operating Conditions/Characteristics" of this specification is not implied. Exposure to absolute maximum ratings conditions for extended periods may affect device reliability.
` Fig. 12 depicts several DDP applications. Since the DDP functions as a video back-end, it must be complemented with additional functionality to form a complete TV set.
` The VPC 32xx family processes all worldwide analog video signals (including the European PALplus) and allows non-linear Panorama aspect ratio conversion. Thus, 4:3 and 16:9 systems can easily be configured by software. The aspect ratio scaling is also used as a sample rate converter to provide a line-locked digital component output bus (YCrCb) compliant to ITU-R-601. All video processing and line-locked clock/data generation is derived from a single 20.25-MHz crystal. An optional adaptive 2H/4H comb filter (VPC 32xx) performs Y/C separation for PAL and NTSC and all of their substandards.
` The VPC 32xxD and the CIP 3250A provide a highquality analog RGB interface with character insertion capability. This allows appropriate processing of external sources such as MPEG 2 set-top boxes in transparent (4:2:2) quality. Furthermore, it translates RGB/ Fast-Blank signals to the common digital video bus and makes those signals available for 100-Hz processing. In some European countries (Italy), this feature is mandatory.
` The IP indicates memory-based image processing, such as scan rate conversion, vertical processing (Zoom), or PAL+ reconstruction.
