I would like to use the I2P function of the ADV7280A to convert an input signal in NTSC (480i) video format.
We would like to convert the input signal in NTSC (480i) video format to a progressive (480p) signal and output it in 8-bit ITU-R BT.656 YCrCb 4:2:2.
A test pattern (color bar) input in NTSC (480i) video format to the ADV7280A is converted to progressive using the I2P function.
The converted signal is converted to progressive.
The converted signal was encoded in 480p30 video format.
Upon checking the encoded signal, we found that the color bar was only displayed in the upper half of the image (see attached figure).
Do you have any ideas about the cause of this problem?
The register is set as follows.
