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
Altera provides four deinterlacing methods.
• Bob with scanline duplication
• Bob with scanline interpolation
• Weave
• Motion-adaptive
