Nokia's d-box family. And remember Bakker Boxes???????????????????coolstf.com Nokia Mediamaster Specific Information The Nokia Mediamaster is the generic name for a series of digital MPEG-2 receivers made by the Finish company, Nokia. Many people refer to this type of receiver as a d-box, but that's really a confusing because there are so many variations of this type of receiver. The d-box and dreambox The d-box is a receiver sold in Germany for the DF-1 package. It contains a Conditional Access Module (CAM), which is a descrambler along with a card slot which uses a card that gets married to the CAM. Echostar receivers also have a CAM, however, theirs is built directly onto the main receiver board. If you have a look at an AlphaStar receiver, you can see the CAM - it's a seperate board that connects between the QPSK receiver and main board. The d-box also contains a modem for PPV reporting (it also does faxing, but I'd probably never want to send a fax from my d-box!). When the d-box was introduced, DF-1 subsidized it's price in Germany in exactly the same way that DirecTV and Echostar subsidize the prices of MPEG-2 receivers here in North America. People in Holland found out that if you took a standard d-box and added a Multichoice card (Multichoice is a Dutch pay TV service), it would work fine. The result was that suddenly a lot of German d-boxes were showing up in Holland which was costing DF-1 plenty of money as they never received a subscription to the DF-1 pay TV service. When the situation got too much for DF-1 they upgraded the firmware of all d-boxes to stop them from receiving Multichoice, which obviously left a lot of people in Holland very unhappy. Because the Nokia box is based on the Motorola 68340 processor and it has a debugging tool built directly into the chip (and a connector on the Nokia motherboard for the debug tool), some enterprising engineers in Holland figured out how to extract the old firmware from d-boxes that worked with Multichoice and re-programmed it (for a fee of course) into the d-boxes that had been in-effect switched off by DF-1. They also patched the code to prevent any future updates from the satellite, while preserving it's ability to be upgraded via the serial port. This receiver is called a "dreambox" from C&J Electronics. It receives all IRDETO scrambled signals (with the correct smart card of course) and also all FTA SCPC and MCPC signals without or without a smart card. Another modified Nokia receiver receiver is available from Bentley Walker and is based on firmware from Bakker Electronics, also in Holland. Since I don't have one of these types of receivers, I can't comment on the firmware, however, I've heard favorable reports about it's operation. Their technical support, however, is somewhat lacking in comparison with C&J Electronics though. Links for all of these companies are at the bottom of the page. Nokia Official FTA receivers Nokia also realized the need for a pan-European (meaning usable all over Europe) FTA MPEG-2 receiver and introduced their 9200S model. This is exactly the same as the 9500S platform that's used by DF-1 (and Telepiu in Italy) except that it is missing the CAM connector and the modem. After all, neither of these would be needed for a FTA receiver. Nokia later revised the 9200S model and introduced the 9600S which in theory works with both FTA and encrypted MPEG-2 signals. It contains two CAM connectors (so that it can be used with multiple scrambling systems) and uses the new Common Access type of CAMs that include the card-reader in the CAM (CAMs are the same size as a type-3 PCMCIA card). The 9600S also included much improved software that does a much better job finding and storing signals than the 9200S.
