Abstract

A system and method for downloading update data to a targeted peripheral device connected to a broadcast receiver such as an integrated receiver decoder (IRD). The update data is received via a broadcast transmission. The system features one or more peripheral devices interconnected to the IRD. The IRD receives a broadcast digital bit stream and processes contents of its header information if it is targeted for the IRD. Next, the IRD determines whether the digital bit stream includes update data to be downloaded and which peripheral device is targeted to receive the update data. Thereafter, the IRD causes the update data to be loaded into the targeted peripheral device.

Claims

1. An entertainment system comprising:

a first peripheral device; and

a broadcast receiver coupled to the first peripheral device, the broadcast receiver configured to receive a broadcast signal, determine whether the broadcast signal includes update data destined for the first peripheral device, and load the update data into the first peripheral device, the broadcast signal including a plurality of data packets transporting the update data, each of the plurality of data packets including a target identification field identifying an integrated receiver decoder to process the update data, and a peripheral identification field indicating whether the first peripheral device is destined to receive the update data processed by the integrated receiver decoder.

2. The entertainment system of claim 1, wherein the first peripheral device includes an analog-input peripheral device.

3. The entertainment system of claim 1, wherein the first peripheral device includes a digital-input peripheral device.

4. The entertainment system of claim 1, wherein each of the plurality of data packets includes a header.

5. The entertainment system of claim 4, wherein each header includes the target identification field, the peripheral identification field and a size field.

6. The entertainment system of claim 1, wherein the target identification field further includes a sequence number indicating an ordering sequence of each data packet to support out-of-order transmission of the plurality of data packets.

7. The entertainment system of claim 1 further comprising at least one second peripheral device coupled to the integrated receiver decoder so that a plurality of peripheral devices are coupled to the integrated receiver decoder.

8. The entertainment system of claim 7, wherein the peripheral identification field identifies one of the plurality of peripheral devices targeted to receive the update data.

9. The entertainment system of claim 5, wherein the size field indicates a byte size of the update data.

10. An entertainment system comprising:

a peripheral device; and

a broadcast receiver coupled to the peripheral device, the broadcast receiver receiving a digital bit stream including a plurality of data packets each including a header portion and a content portion, the header portion including a target identification field indicating whether the digital bit stream is to be processed by the broadcast receiver, the header portion further including a peripheral identification field indicating whether the peripheral device is targeted to receive the update data.

11. The entertainment system of claim 10, wherein the broadcast receiver includes an integrated receiver decoder.

12. The entertainment system of claim 10, wherein the peripheral device includes an analog-input peripheral device.

13. The entertainment system of claim 10, wherein the peripheral device includes a digital-input peripheral device.

14. A method for loading update data into a peripheral device, the method comprising the steps of:

determining whether a plurality of data packets is targeted to a broadcast receiver; and

determining whether the plurality of data packets include update data to be downloaded, wherein if so, examining a peripheral identification field to determine if the update data is to be downloaded to the peripheral device and modifying the update data into a format recognized by the peripheral device.

15. The method of claim 14, wherein determining whether the plurality of data packets is targeted to the broadcast receiver includes the step of accessing contents of a target identification field in a header of a first data packet of the plurality of data packets.

16. The method of claim 15, wherein determining whether the plurality of data packets includes update data includes the step of accessing contents of a sub-field of the target identification field to determine whether at least one predetermined bit is set to indicate that the update data is to be downloaded.

17. An entertainment system comprising:

a first peripheral device; and

an integrated receiver decoder coupled to the first peripheral device, the integrated receiver decoder includes

an antenna to receive a broadcast signal, and

internal circuitry coupled to the antenna, the internal circuitry accesses a target identification field in a header information of the broadcast signal to determine whether the broadcast signal is directed to the integrated receiver decoder, the internal circuitry also determines from a peripheral identification field in the header information of the broadcast signal to determine whether the broadcast signal is targeted for the first peripheral device.

18. The entertainment system of claim 17, wherein the logic circuitry of the integrated receiver decoder further determines from the header information whether data of the broadcast signal is targeted for the first peripheral device.

20. The entertainment system of claim 17, wherein each of the plurality of IRDs included in the IRD group is further configured to examine a target identification field in each of the plurality of packets to determine whether the broadcast signal is intended to be processed by the plurality of IRDs included the IRD group.

21. The entertainment system of claim 20, wherein the plurality of IRDs included in the IRD group are located within one geographic location.

22. The entertainment system of claim 20, wherein the plurality of IRDs included in the IRD group are configured to support one particular digital satellite system (DSS) service package.

19. An entertainment system comprising:

a first peripheral device; and

an integrated receiver decoder (IRD) group including a plurality of IRDs coupled to the first peripheral device,

each of the plurality of IRDs configured to receive a plurality of packets representing a broadcast signal,

each of the plurality of IRDs also configured to examine a peripheral identification field in each of the plurality of packets to determine whether the broadcast signal is targeted for the first peripheral device.
