Hi all,
I want to build and share my own televisor circuit, but I want to ask a few things.
What is the most widely accepted format today (32 lines by...? or...?)
It is not clear to me how the NBTV signal waveform is constructed.
I understand that each frame is constructed from 32 vertical lines (in case of the 32 lines format).
Is there any line sync and frame sync pulses and what are these? (negative, positive, levels?, at the start or at the end of the line/frame?)
I need to know these things before I build and share with you my interesting televisor (It will use a totally different display system).
By the way, please inform me if there is such a circuit built from discrete components (not ICs)
Thank you
