I have a question about details of I2P (interlace to progressive) conversion of ADV7282A-M.
The expert answered on following thread as follows:
>The deinterlacer in the ADV7280, ADV7280-M, ADV7282, ADV7282-M all work on a line doubling rather than on a frame buffering technique.
>This gives the advantage of reduced delay on the output. Also large external memory is not needed.
>The line doubling technique uses a propriety analog devices algorithm.
>It interpolates between two lines (e.g. lines 1 and 3 on an odd frame) to generate the an additional line (e.g. line 2).
>A smoothing filter is also applied to reduce the effect of low angle noise (i.e. jaggies).
Please tell me more details of the I2P interpolation.
About your comment "It interpolates between two lines (e.g. lines 1 and 3 on an odd frame) to generate the an additional line (e.g. line 2). ",
=> Does it mean linear interpolation? (Does it mean that line2 is interpolated by linear?)
Is it the way to generate line 2 from average of line 1 and line 3?
