Functional Overview
1. Input signal formats
The digital data port supports the following input signal formats.
30-bit RGB
30-bit (4:4:4) YCbCr/YPbPr
20-bit (4:2:2) YCbCr/YPbPr
10-bit signals conforming to the ITU-R BT.656 standard (horizontal and vertical sync inputs required)
NTSC (480i/480p), PAL (576i/576p), and HD (1080i/720p)
RGB (up to 135 MHz)
2. IP conversion block
For NTSC (480i) and PAL (576i) inputs the LC749450NW provides motion adaptive IP conversion or cinema IP
conversion (3:2 pull down) with both 2D/3D noise reduction and cross color/cross luminance cancellation.
External SDRAM (either 2
× 16 Mbits or 1 × 64 Mbits) is required when the functions of this block are enabled.
This block is set to bypass mode for 480p, 576p, 1080i, 720p, and PC (RGB) inputs.
(1) Motion adaptive IP conversion
The LC749450NW performs motion detection for each pixel that enters the IP conversion block. Based on that
result, the block performs interlaced to progressive conversion. Pixels that are found to be static are interpolated
between fields and pixels that are found to be moving are interpolated within the field.
Since this circuit takes correlations in the diagonal directions into account when performing inter-field
interpolation for moving sections of the image, it can create smooth video with minimal stair-stepping artifacts
(jaggies). Furthermore, this function can handle images that range from relaxed smooth video to video with violent
motion by setting parameters and changing the motion threshold values for each pixel.
