			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
