Hi i think  compossed video is very DIFICULT  process signals sync, video levels and speed process

Other option is use usb web cam   
I think cypress makes some..check it out, cypress uC which support USB.
PIC, AVR  may not have enough processing power speed  to dowhat you want with elegance
YOU MAYBE RUN PIC TO 300 MHZ  TO PROCESS ALL DIGITAL SIGNALS, IS NO POSSIBLE TODAY


Before you get involved with any type of data transmition, check the bandwidth
 (eg 320x240 x30fps = 2.3Mb/sec or about 2250kbps just for video

maybe this help to you  some idea:
