Subject: Re: [ee]: Outputting to TV? To: PICLIST@MITVMA.MIT.EDU X-RCPT-TO: Status: R X-UIDL: 277600712 X-Evolution-Source: pop://mailinglist%40farcite.net@mail.farcite.net/ X-Evolution: 00000792-0000 Unfortunately this kind of thing should be done step by step. First you learn how to do the composite video sync, then you create the interlaced stable "odd black" - "even white" video signal, then, you draw a big rectangle in middle of screen, then, you learn how to calculate sine(x) and produce a big nice round circle, then you can go for characters drawing and character generators, then, after you have absolute knowledge about it, including plenty of available processing power in between vertical retrace, perhaps it would be time for color burst signals and such.
