IP Cores 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
Deinterlacing Methods
