Any SDTV Video Decoder with 4:4:4 output?

Hi we are looking for a video decoder which can convert PAL/NTSC composite, S-Video and YPrPb.
Output format doesn't matter, it can be YCrCb 4:4:4 or RGB (it will go to FPGA so we can do any conversion).
However all SDTV decoders I found only produce 4:2:2, which means horizontal resolution for color components is only 360 pixels.
