Abstract

The invention provides for an audio visual display apparatus (10) arranged to receive a broadcast signal comprising a video element and an audio element, wherein the audio element includes an audio description element providing a description of at least some of the video content, the apparatus (10) including means for switching (24) to output the said audio description element in place of the video element and which switching is responsive to a deterioration in an operating characteristic of the apparatus.

Claims

1. An audio visual display apparatus arranged to receive a broadcast signal comprising a video element and an audio element, wherein the audio element includes an audio description element providing a description of at least some of the video content, the apparatus including means for switching to output the said audio description element in place of the video element in response to a deterioration in an operating characteristic associated with the apparatus.

2. Apparatus as claimed in claim 1 and including means for monitoring the said operating characteristics.

3. Apparatus as claimed in claim 2, wherein the said means for monitoring is arranged to monitor battery level within the apparatus.

4. Apparatus as claimed in claim 2 wherein the said means for monitoring the characteristic is arranged to monitor data-handling capacity within the apparatus.

5. Apparatus as claimed in claim 4, wherein the means for monitoring is arranged to monitor memory capacity.

6. Apparatus as claimed in claim 3, wherein the said means for monitoring the operating characteristic is arranged to monitor the quality of the broadcast signal as received at the apparatus.

7. Apparatus as claimed in claim 6, wherein the means for monitoring the characteristic arranged to monitor the picture quality of the video element.

8. Apparatus as claimed in claim 1 and comprising a mobile radio communications device.

9. A method of receiving and displaying a broadcast signal comprising a video element and an audio element wherein the audio element includes an audio description element providing a description of at least some of the video content, the method including the step of switching to output the said audio description element in place of the video element in response to a deterioration in an operating characteristic associated with the apparatus.

10. A method as claimed in claim 9 and including the step of monitoring the said operating characteristic.

11. A method as claimed in claim 10 and including the step of monitoring battery level within the apparatus.

12. A method as claimed in claim 10, and including the step of data handling capacity within the apparatus.

13. A method as claimed in claim 12, and including the step of memory capacity.

14. A method as claimed in claim 10, and including the step of monitoring the quality of the broadcast signal as received at the apparatus.

15. A method as claimed in claim 12 and including the step of monitoring picture quality.
