Clocked video output

Do you think such a structure is feasible.... Can i do without a frame buffer at the end?

Or will i get a buffer under run?

Is there any better way you all can suggest to be able to send a video feed to be able to be shown on a screen and recorded on an sd card at the same time?

I thought before the entrance to each of the interfaces i would put a ONChip Fifo, which would be dual clock hence allowing me to run the system at different clock speeds..

I hope you all dont mind giving me ideas, thanking you nadeem jamal
