Shared HDATA among multiple ADV212s

I have an application using multiple ADV212 chips to decode a larger/faster image than a single chip can handle.  There are multiple documents (AN-796, TN-0003, ADV212 datasheet) which show a common HDATA bus between the CPU and all the ADV212 ICs.  How does each ADV212 know to only use part of the image (luma/chroma or top/bottom)?  Is each chip just set up with registers to only work on part of the image and it ignores the rest automatically?
