The video interfacing standards are set by ETSI(for European DVB). If you search ETSI site you will find them but the parallel interface is too obvious anyway, just 8 bits data plus clk plus data_valid. It is indeed called SPI = synchronous Parallel Interface as opposed to the more involved ASI(Asynchrnous Serial Interface). There is also SSI(Synchronous Serial Interface) but don't know if anybody uses it.
