the 6100 9200 and 9400 receivers. In February 2008, Bell Satellite TV announced a second smartcard swap involving all its receivers with the exception of the 6141 and 9241 models. This was required due to the massive intrusion of ExpressVu signals that occurred with the Nagravision 2 encryption. The latter standard was implemented on May 27, 2005, to end the unlicensed access that occurred with the first Nagravision system. Bell Satellite TV has upgraded to Nagravision 3 as the new encryption standard, to prevent unauthorized access to pay TV channels. The only means to view Bell Satellite TV illegally is through IKS (Internet Key Sharing) devices which include NFusion FTA and the Slinger. Both devices are not hacks but only means of a workaround. Bell Satellite TV is currently working towards shutting down these types of devices. No known hacks exist for the Nagravision 3 protocol. Newer receivers incorporate smartchips instead, which are permanently installed inside the receiver. According to Bell Tech Support, a 4100 with smartchip will require a newer smartcard upgrade. Unsupported hardware In 2009, Bell 6000 receiver owners received letters in the mail that state they must swap to a 6141 or face losing programming as Bell Satellite TV deployed MPEG-4 with 8PSK. The 6000 does support the use of 8PSK with an add-in module, but Bell Satellite TV decided not to send out these as the 6000 is old and most customers will be wanting to upgrade to a 6141 which can have a hard disk drive added to it to be used as a PVR. The guide for programming information is also updated and stores more information in its database than the 6000. Later, starting in October 2011, Bell announced that it would replace all currently active MPEG-2 HD satellite receivers, specifically the 6100 and 9200 models, with MPEG-4 HD receivers. This is to allow current HD channels to be encoded in MPEG-4 instead of MPEG-2, providing free space for 43 additional local standard definition channels which will begin airing in September 2012. 6100 owners will receive the latest 6131 HD receiver, while 9200 owners will receive either a 9241 or a 9242. If the 9200 receiver was used for two televisions, Bell will provide either a 9241 with a 5900 or a 9242. Both setups permit the two televisions to watch Bell Satellite TV but recording and playback with the 5900 does not equal
