I have NTSC video that I want to securely encrypt and send over 10-100' of coax and then decrypt at the other end.
Do you have any parts that do this or suggestions?
Depends what they want but the simplest would be ADV7180 or ADV7182. Encoder would be ADV734X or ADV739X.
No single part would do anything like that. Is the data over the coax analog or digital? I would think that using a decoder to digitze it, then a Blackfin to encrypt followed by either an encoder (analog) or just sending it out digitally would be a reasonable solution. The other end would be the reverse.
Could be analog or digital, which ever is easier.
"....using a decoder to digitize it...." Do you have a part number(s) for parts at each end
or if not, any other semiconductor guys I should check with?
