That was covered in the link I posted above about smart card technology. The satellite cards are nothing but smart cards (cards similar to credit cards with embedded and programmable chips). They are used for a variety of other purposes. I heard that someone had reprogrammed their American Express smart card to decode satellite broadcasts, but that's probably an apocryphal story; I don't know enough about the technology to know if that could be done.

OkeeDon,
They look the same to the novice but they are distinctly different. Satellite cards have ASIC processors with very specific commands for decrypting Video packets...nothing else is like it because NDS and DTV own the rights...
Dont listen to the wannabes who say the Amex card and satellite cards can be interchangable...anybody who thinks this can be used as an excuse will be sadly mistaken...
Your friend would use an EEPROM programmer, not a smart card programmer or ISO 7816 device...The progammers you mention arent really true ISO7816 devices and here is why:
There are going to be a few details which everyone will need to get straight if they wish to use this defense: The underlying problem with the 'legitimate use' defense resides in the fact that the iso 7816 readers which are sold and used in the dss community are fundamantally different from the readers used by the rest of the smartcard industry...
The difference lies in the way the reader communicates; a few years back, the various smartcard manufacturers and developers formed a standard which created a single communication platform by which all readers and software can be used easily; This standard is called PCSC and the specification can be found at
http://www.pcscworkgroup.com/ . The basis of the standard and what makes the readers different is that a PCSC compliant reader contains all the firmware on the reader, which allows the reader to be recognized by the computer operating system and any of the programs running with the PCSC standard. The end result is that any PCSC complaint reader can be used with any PSCS complaint software without any compatibility problems.
The iso 7816 readers which we are all familiar with and are used for the purpose of dss hacking do not conform to this standard; these are what are known as "dumbmouse readers" since they only contain the basic rs232 serial interface and will not work directly with PCSC software.
If DTV ends up going to court to fight over the legality of the programmers, they will use this issue as their "ace in the hole" as it is highly unlikely that if someone was purchasing programmers from a dss website for their company to facilitate secure logon, they would have a very difficult time getting them working. They will also use the fact that not one piece of dss software has ever been designed to use the PCSC standard; something that should have been done long ago to promote cross-usability between the different devices..
Its even worse to prove legal uses for "Unlooper's", bootloaders, programmed cards, Atmels, etc...
You really have no chance to be successful in making your case if you get a letter or summons. People are fooling themselves if they feel they will be successful in just saying
its a legal device with many uses. Be prepared to back it up along with family and possible friends...
Just becareful and dont listen to wishful thinking people. They will sell you down the river before you know it and realize it...
