1. Input
1-1 Input signal format (Digital input)
Digital data port supports the following signal input formats.
24bit (4:4:4) YCbCr/RGB: NTSC/PAL (480i/576i), 480p, 576p, HD (1080i/720p)
16bit (4:2:2) YCbCr: NTSC/PAL (480i/576i), 480p, 576p, HD (1080i/720p)
8bit Based on ITU-R BT656system (H/V sync input is needed): NTSC/PAL (480i/576i)
Digital 2 system input such as 16bit (4:2:2) YCbCr + 8bit (ITU-R BT656), 8bit (ITU-R BT656) +
8bit (ITU-R BT656) are possible
1-2 Input signal format (Analog input)
Analog port can be connected to all of the following input.
CVBS
× 2ch: Composite input 2CH
S-Video: S video input 1CH
YPbPr input (Supports 480i/576i, 480p/576p, 1080i, 720p input): Component input 2 system
2. Digital Video Decoder Block
This LSI carries video decoder which converts the video signal of NTSC, PAL and SECAM or Component
video signal into digital picture signal.
It decodes Digital picture data by inputting the video signals of NTSC, PAL and SECAM which are converted
from Analog to Digital. It supports composite video signal, S video signal and component signal (480i).
3. De-interlacing Block
When inputting NTSC (480i) and PAL (576i), it can implement motion adaptive De-interlacing, cinema mode
de-interlace, 3D noise reduction and cross color/cross luminance canceller. At 480p, 576p, 1080i, 720p, this block is
set to the through state.
3-1. Motion adaptive De-interlacing
At De-interlacing block, it operates the movement detection to every pixel that inputted. As a result, it does
interpolation between front and back field to the pixel that judged as static, and does interpolation inside field
to the pixel that judged as move. So de-interlacing can be done. In that case, as for interpolation in between
field of move part, it is possible to produce less notched (less-jaggy) and smooth image because of interpolation
that considers the correlation of oblique direction.
