High Performance Scaler (HPS) offers two-dimensional, phase correct data processing for improved
signal quality of scaled video data, especially for compression applications
q
Horizontal and vertical FIR filters with up to 65 taps
q
Horizontal upscaling (zoom) supports e.g. CCIR to square pixel conversion
q
Additional Binary Ratio Scaler (BRS) supports CIF and QCIF formats, especially for video phone and
video conferencing.
q
Interfacing
Dual D1 (8-bit, CCIR 656) video I/O interface
q
DMSD2 compatible (16-bit YUV) video input interface
q
