Video timings for QCIF 176x144 resolution

Gomathi Chan

I'm in need of the following Video timings for QCIF 176x144 resolution.

1. Horizontal Front Porch
2. Horizontal Back Porch
3. Horizontal Sync Pulse Width
4. Vertical Front Porch
5. Vertical Back Porch
6. Vertical Sync Pulse Width

I need it to be filled in EDID 1.3. I tried to find how to calculate those values. But, I'm able to find standard timing values for VGA timings. But, not QCIF. Are there any standard set of values? Or please guide me how to calculate these values.
