Abstract

An automated system and method for pre-processing software update parameters for transmission to IRDs via traditional broadcasts without the necessity for repeated manual intervention. Generally, the present invention is a system that automatically generates software download commands containing all the necessary parameters that an IRD in a satellite-communication network requires to complete a software download, such as time, frequency, the location of the software within the data stream, among other parameters. The invention provides software upgrade data to be transmitted in data packets that comprise a satellite broadcast. The transmitted information includes target broadcast receiver (IRD) identification information and software upgrade information to determine if the targeted IRD is indeed the correct recipient of the software upgrade data, and if the IRD requires a software upgrade. The urgency of the upgrade is determined to allow upgrades to be mandatory, optional, deferred to a later time period, or cancelled. The upgrade information is broadcast via typical satellite transmissions and occurs periodically without any human intervention, depending on the current upgrade version of the IRD.

Claims

1. A method for automatically generating a software download command for upgrading IRDs in a satellite-based communication network comprising the steps of:

obtaining IRD upgrade code and IRD information private to an IRD'"'"'s manufacturer;

generating a file containing the private IRD manufacturer information and formatted IRD upgrade code;

transmitting the formatted IRD upgrade code to a broadcast center;

entering IRD upgrade parameters;

selecting a target IRD or target geographical location containing IRDs which are to receive the upgrade code;

generating a software download command using a single software platform, said software download command including formatted target IRD information;

creating a batch file including said software download command and said formatted IRD upgrade code; and

broadcasting contents of said batch file in a traditional satellite uplink broadcast.

2. A method for providing software upgrade data to a receiver in a satellite broadcast system comprising the steps of:

notifying a broadcast receiver when a software upgrade is available;

determining the urgency of said software upgrade for said broadcast receiver;

scheduling a software upgrade session for the broadcast receiver, said software session comprising one or more software upgrade data transmissions; and

periodically transmitting data packets containing software upgrade data for said scheduled software upgrade session, to said broadcast receiver.

3. The method of claim 2 wherein said step of notifying the broadcast receiver when said software upgrade is available is comprised of the step of providing an upgrade announcement message, transmitted in said data packets.

4. The method of claim 3 wherein the step of scheduling said software upgrade session comprises the steps of:

storing one or more private identification parameters within a memory storage device located in each said broadcast receiver, said private identification parameters provided by the IRD'"'"'s manufacturer;

transmitting, within said data packets, public identification parameters, said public identification parameters provided by a satellite television broadcast provider; and

determining if said transmitted public identification parameters are equal to said stored private identification parameters, and if not equal, canceling said software upgrade session.

5. The method of claim 2 further comprising the steps of determining if said software upgrade session is comprised of more than one said transmission, and if so, sequentially storing, in a memory storage medium, subsequently transmitted software upgrade data corresponding to the scheduled software upgrade session.

6. A system for providing software upgrade data to a receiver in a satellite broadcast system comprising:

one or more peripheral devices; and

a broadcast receiver electrically connected to said one or more peripheral devices for notifying a broadcast receiver when a software upgrade is available, said broadcast receiver capable of receiving notification of transmitted data packets containing a broadcast receiver software upgrade, wherein said transmitted data packets comprises means for determining the urgency of said software upgrade for said broadcast receiver, means for scheduling a software upgrade session for the broadcast receiver, said software session comprising one or more software upgrade data transmissions and means for periodically transmitting data packets containing software upgrade data for said scheduled software upgrade session, to said broadcast receiver.

7. The system of claim 6 wherein the broadcast receiver is notified of said software upgrade by receiving an upgrade announcement message, transmitted via said data packets.

8. The system of claim 6 wherein said means for scheduling said software upgrade session comprises:

means for storing one or more private identification parameters within a memory storage device located in each said broadcast receiver, said private identification parameters provided by the IRD'"'"'s manufacturer;

means for transmitting, within said data packets, public identification parameters, said public identification parameters provided by a satellite television broadcast provider; and

means for determining if said transmitted public identification parameters are equal to said stored private identification parameters, and if not equal, canceling said software upgrade session.

9. The system of claim 8 further comprising means for determining if said software upgrade session is comprised of more than one said transmission, and if so, providing means for sequentially storing, in a memory storage medium, subsequently transmitted software upgrade data corresponding to the scheduled software upgrade session.

10. The system of claim 6 wherein said memory storage medium is non-volatile memory.

11. A computer program stored in a computer readable medium, embodying instructions to perform a method for providing software upgrade data to a receiver in a satellite broadcast system comprising the steps of:

notifying the broadcast receiver when a software upgrade is available;

determining the urgency of said software upgrade for said broadcast receiver;

scheduling a software upgrade session for the broadcast receiver, said software session comprising one or more software upgrade data transmissions; and

periodically transmitting data packets containing software upgrade data for said scheduled software upgrade session, to said broadcast receiver.

12. The program of claim 11 wherein said step of notifying the broadcast receiver when said software upgrade is available is comprised of an upgrade announcement message, transmitted in said data packets.

13. The program of claim 12 wherein the step of scheduling said software upgrade session comprises the steps of:

storing one or more private identification parameters within a memory storage device located in each said broadcast receiver, said private identification parameters provided by the IRD'"'"'s manufacturer;

transmitting, within said data packets, public identification parameters, said public identification parameters provided by a satellite television broadcast provider; and

determining if said transmitted public identification parameters are equal to said stored private identification parameters, and if not equal, canceling said software upgrade session.

14. The program of claim 12 further comprising the steps of determining if said software upgrade session is comprised of more than one said transmission, and if so, sequentially storing, in a memory storage medium, subsequently transmitted software upgrade data corresponding to the scheduled software upgrade session.
