Abstract

A digital broadcast receiver and method are provided. The digital broadcast receiver comprises an input, an anti-virus unit and a host interface. The input is configured to receive a digital broadcast. The anti-virus unit is configured to carry out an anti-virus check on the at least one data channel received as part of the digital broadcast. The host interface is configured to provide the at least one decoded data channel to a host.

First claim

The invention claimed is:

1. A digital broadcast receiver comprising:
an antenna configured to receive a digital broadcast;
an anti-virus unit, located at an antenna side of the digital broadcast receiver, configured to carry out an anti-virus check and identify malicious data on at least one data channel received as part of the digital broadcast; and
a host interface configured to provide the at least one decoded data channel including malicious data and an indication of a presence of malicious content in the malicious data to a host.

2. The digital broadcast receiver of claim 1 , wherein the at least one data channel is an encoded data channel.

3. The digital broadcast receiver of claim 1 , wherein the at least one data channel comprises all of the encoded data channels received as part of the digital broadcast.

4. The digital broadcast receiver of claim 1 , further comprising
a first processing path configured to decode a first data channel of the digital broadcast.

5. The digital broadcast receiver of claim 4 , wherein the antivirus unit is configured to carry out the antivirus check on the decoded first data channel.

6. The digital broadcast receiver of claim 1 , wherein the anti-virus unit is configured to carry out the anti-virus check on the at least one data channel when that data channel is requested by a host processor.

7. The digital broadcast receiver of claim 1 , wherein when the malicious data is identified by the anti-virus check, the anti-virus unit is further configured to forward an indication of the malicious data to the host processor.

8. The digital broadcast receiver of claim 7 , wherein when the malicious data is identified by the anti-virus check, the anti-virus unit is further configured to delete the malicious data.

9. The digital broadcast receiver of claim 7 , wherein when the malicious data is identified by the anti-virus check, the anti-virus unit is further configured to forward the malicious data to the host processor along with the indication.

10. The digital broadcast receiver of claim 1 , wherein when the malicious data is not identified by the anti-virus check, the anti-virus unit is further configured to forward the at least one decoded data stream to the host processor.

11. The digital broadcast receiver of claim 1 , wherein the digital broadcast receiver is a digital audio broadcast DAB+ receiver.

12. A method comprising:
receiving, with an antenna, a digital broadcast comprising a plurality of data channels;
carrying out, at an antenna side of the digital broadcast receiver, an anti-virus check that identifies malicious data on at least one of the plurality of data channels; and
providing the at least one decoded data channel including malicious data and an indication of a presence of malicious content in the malicious data to a host.

13. The method of claim 12 , wherein the at least one data channel is an encoded data channel.

14. The method of claim 12 , further comprising
carrying out the antivirus check on the plurality of data channels prior to any one of the data channels being decoded.

15. The method of claim 12 , further comprising
decoding a first data channel of the digital broadcast.

16. The digital broadcast receiver of claim 1 , wherein the antenna is coupled to a tuner.

17. The digital broadcast receiver of claim 16 , wherein the anti-virus check is performed on data output by the tuner.
