Does the interlaced to progressive conversion in the ADV7842/44 have motion compensation? How is the deinterlacing carried out? Is the external SDRAM that is used for the comb filter also used for deinterlacing?
Please find the details about ADV7842de- interlacing in UG-214 ADV7842 hardware user guide, section 7.18 interlaced to progressive which is available at ADV7842 Design Support Files
Please also refer the following threads, believe that it would be helpful to refer
OK, I can infer from the documents you referenced, that it is NOT motion compensated. Yet there is memory available for the comb filter that could have been used for motion compensated deinterlacing. A pity. I think a 2D comb combined with using the SDRAM for motion adaptive deinterlace would result in a much better image than what you can now achieve with the part. Just my opinion.
interlace to progressive is only line doubling. Motion detection is used as part of the 3D comb filter. Implementing motion adaptive deinterlacing was out of the original design specifications for this part limiting the total DDR bandwidth to that only required by the 3D comb filters and Timing Block Control.
Thanks Jeyasudha, this is what I needed and a good reference source. How about adding UG-214 to the ADV7844 doc package?
