Digital VSB (Vestigial Side Band) Modulator for Analog TV

The task of my student research project is to implement a digital VSB modulator for analog TV in an FPGA. The design has three inputs: CVBS (Color Video Baseband Signal) and audio1 (mono/left) as well as audio2 (right) - digital sampled as YCbCr and I2S, respectively. The output shall be "sampled" analog TV baseband (16-bit real-values at 150 Mhz clock) as input for direct digital synthesis to TV RF (UHV..VHF).

Can anyone help me with an idea how to solve this task?

Thanks in advance!

    You can get some ideas about video encoder operation from PAL/NTSC encoder at opencores.org or from datasheets of encoder IC, e. g. from Analog or Cyrrus.
