Feature

Broadcast Deinterlacer

• Converts interlaced video to progressive video using

high quality motion-adaptive algorithm. This algorithm

enhances the edge-adaptive reconstruction and improves

image quality, with significantly enhanced performance

for combined video and film sequences

• Provides double -buffering in external RAM

• Stores the input video fields in the external memory and

concurrently uses these input video fields to construct

deinterlaced frames; buffers one field of video before

commencing deinterlacing

• Provides the option to detect both 3:2 and 2:2 cadences

in the input video sequence, and perform a reverse

telecine operation for perfect restoration of the original

progressive video

• Supports only YCbCr 422 color space with 8, 9, or 10 bits

of data per color plane

• Bad edit detection and correction

• Visualization modes for motion and film content to

enable fine tuning of deinterlaced output

• Motion calculation that replaces motion estimation

• Dedicated scene change detection logic
