5.3 YUV to RGB Space Converter
For video input (EnYUV = 1), the input YUV (YCbCr) data are converted internally into RGB format by
the following equations.
R = Y + 1.371 (Cr – 128)
G = Y - 0.698 (Cr – 128) – 0.336 (Cb – 128)
B = Y + 1.732 (Cb – 128)
5.4 De-Interlace
For interlace input, the input image is separated into even and odd fields. Due to no frame buffer
available, STK6005 employs the spatial interpolation method to calculate the missing lines from their
neighboring lines. Internal register 0x1C should be set to enable a de-interlace function.
5.5 Input Synchronous Signals Processing
STK6005 provides a composite sync separation hardware to separate V-Sync from C-Sync and re-
generate the H-Sync for the external ADC chip. STK6005 supports three combinations of input H / V
synchronous signals (before ADC) which are composite sync signal from CSync or from VGAHS port, and
separated sync signals from the VGAHS and VSync ports. An H-Sync output will be re-generated from
