System and method for delivering satellite services at multiple security levels

摘要

The disclosed embodiments relate to a system and method for delivering satellite services at multiple security levels. More specifically, there is provided a method comprising determining a level of security supported by a first set top box (22a), encoding a first IP packet containing a satellite service using the level of security supported by the first set top box (22a), transmitting the first IP encoded packet to the first set top box (22a), determining a level of security supported by a second set top box (22b), wherein the level of security supported by the second set top box (22b) is different from the level of security of the first set top box (22a), encoding a second IP packet containing a satellite service using the level of security supported by the second set top box (22b); and transmitting the second encoded IP packet to the second set top box (22b).

主权项

1. A method comprising:
determining a first level of security supported by a device responsive to a request from the device; encoding a signal received from an audio video service provider into first IP packets using the determined first level of security supported by the device, wherein said first IP packets contain data from said audio video service provider that has been encoded using the determined first level of security supported by the first device and wherein encoding is performed after determining the first level of security and continues as further data is received from said audio video service provider; transmitting the first IP encoded packets to at least the first device; determining a second level of security supported by a second device responsive to a request from the second device; responsive to a determination that the second level of security supported by the second device is different from the first level of security supported by the first device, encoding a signal received from said audio video service provider into second IP packets using the determined second level of security supported by the second device, wherein said second IP packets contain data from said media delivery service that has been encoded using the determined second level of security supported by the second device and wherein said encoding is performed after determining the second level of security supported by the second device and continues as further data is received from said audio video service provider; and transmitting the second encoded IP packets to at least the second device while the first device continues receiving the first encoded IP packets.
