busybee Writing Dream log

I slept a lot more than usual last night, and with it came more dreams than usual.

First Dream

In the first dream, my sister wanted to know how exactly it is that three color channels can be encoded into a single composite video signal. So I showed her Dexter-style, by shrinking both of us down and romping through graphs showing how RGB gets converted to YPbPr/YUV/YIQ, then into YC through phase tricks, then into just Y through further phase tricks. Then things started to fall apart when I got into the actual decoding bit and comb filters and so on.

Then I woke up, and drifted back to sleep.
