Function Full Screen PIP/POP
3D-Comb Y
MDDi Up to 1080i MDDi
When POP mode, Main=AV, Sub=1080I, only one of HD MDDi and Comb
can be enable.
(for POP)Case i: Main=AV(with 3D Comb), Sub=1080i(Bob mode)
(for POP)Case ii: Main=1080i(Bob mode), Sub=AV(with 3D Comb)
(for POP)Case iii: Main=AV(without 3D Comb), Sub=1080i(HD MDDi)
(for POP)Case iv: Main=1080i(HD MDDi), Sub= AV(without 3D Comb)
Scale mode Normal/Full
When PIP mode, there is no constraint in 3D-Comb and MDDi.
Normal/Full
VGA timing Up to
1280x1024@75Hz
Up to 1280x1024x60Hz
Panel 1080P
� For PIP/POP mode, 1280x1024 should be under 60Hz.
� Case lists are evaluated when Dram clock = 169 MHz,DDRx2.
� Flash Usage
� Flash is used to store FW code, fonts, bitmaps, big tables for VGA, Video, Gamma..
� In our demo system, we can support 2-4 languages within 1MB flash.
� For single country, we need around 20KB to store font data.
� For more bitmaps, we need more flash space to store them.
� 2Mbytes is recommended to build a general TV model.
