ADV7391 Vertical Blanking Insertion (NTSC)

I have a couple questions regarding the ADV7391 vertical blanking insertion support:


1) Which ADV7391 supported VBI standard provides the highest overall bitrate of ancillary data for NTSC?


2) What would be the best way to create a general purpose "side-band" data pipe using the ADV7391 of the highest 100% recoverable bitrate? In other words, if i wanted to send non-standard ancillary data through the ADV7391 from the blanking periods of a ITU-R BT.656 8-bit parallel transport, and recover it in a video A/D such as the ADV7403, what would be the most effective method?
