The Deinterlacing IP cores provide deinterlacing algorithms.

Interlaced video is commonly used in television standards such as phase alternation line (PAL) and national television system committee (NTSC), but progressive video is required by LCD displays and is often more useful for subsequent image processing functions.

Additionally these cores also provide double -buffering or triple-buffering in external RAM. Doublebuffering helps solve throughput problems (burstiness) in video systems. Triple-buffering provides simple frame rate conversion.

IP Cores		Feature
Deinterlacer		• Converts interlaced video to progressive video using a
		bob, weave, or simple motion-adaptive algorithm
		• Provides double -buffering or triple-buffering in external
		RAM
Deinterlacer II		• Converts interlaced video to progressive video using
		high quality motion-adaptive algorithm. This algorithm
		uses a kernel of pixels and significantly enhances the
		edge-adaptive reconstruction to improve image quality
		• 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
		• 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
