Abstract

At lease one operating condition associated with an end user (120) of a network is obtained. Based upon the operating condition, a high bit-rate media feed being made to the end user (120) is halted. Thereafter, a lower bit rate media feed may be supplied to the end user in place of the high bit-rate media feed.

Claims

1. A method of increasing performance of a network comprising the steps of:

obtaining at least one operating condition associated with an end user in a network;

supplying a high bit-rate media feed to the end user; and

based upon the at least one operating condition, selectively halting the supplying of the high bit-rate media feed to the end user and thereafter supplying for at least a predetermined amount of time a lower bit-rate media feed to the end user instead of the high bit-rate media feed.

2. The method of claim 1 further comprising the step of halting the lower bit-rate media feed and conditionally restarting the high bit-rate media feed.

3. The method of claim 1 wherein obtaining the at least one operating condition comprises obtaining at least one operating condition selected from a group comprising:

a Radio Frequency (RF) condition;

a system load condition;

a battery life condition of a mobile station;

a signal strength condition; and

a mobility condition.

4. The method of claim 1 wherein supplying a lower bit-rate media feed comprises supplying a media to the end user, the media selected from a group comprising:

a commercial advertisement;

a highlight video clip;

a replay video clip;

currently available music;

a slide;

a video Extensible Markup Language (XML) stream having a lower bit rate;

a media having a less strict audio threshold;

a media having a less strict motion threshold;

a preloaded educational media; and

a media with a reduced amount of feature changes.

5. The method of claim 1 wherein supplying a low bit-rate media feed comprises slowing a play-out rate of media from a play-out buffer.

6. The method of claim 1 further comprising the step of selecting the lower bit-rate media between multiple media streams.

7. The method of claim 1 wherein halting the high bit-rate media feed comprises only halting the high bit-rate media feed when consistently poor RF conditions are detected.

8. A method of improving system performance comprising the steps of:

determining a quality of a Radio Frequency (RF) connection supplying a high bit-rate media feed to an end user; and

whenever the quality is determined to be below a threshold, adjusting at least one characteristic of the high bit-rate media feed to improve the quality.

9. The method of claim 8 wherein determining a quality comprises evaluating an operating condition, the operating condition being selected from a group comprising:

a system loading condition;

a Radio Frequency (RF) condition;

a battery life condition of a mobile station;

a signal strength condition; and

a mobility condition.

10. The method of claim 8 wherein adjusting at least one characteristic comprises adjusting an operating characteristic of a security camera to improve quality.

11. The method of claim 8 wherein adjusting at least one characteristic comprises replacing the high bit-rate media feed with a low bit-rate media feed.

12. The method of claim 11 wherein supplying a low bit-rate media feed comprises supplying a low bit-rate media feed selected from a group comprising:

a commercial advertisement;

a highlight video clip;

a replay video clip;

currently available music;

a slide;

a video XML stream having a lower bit rate;

a media having a less strict audio threshold;

a media having a less strict motion threshold;

a preloaded educational media; and

a media with a reduced amount of feature changes.

13. A device for improving user capacity comprising:

a transmitter having an output;

a receiver having an input; and

a controller coupled to the receiver and the transmitter, the controller programmed to receive at least one operating condition associated with a wireless user at the input of the receiver and supplying a high bit-rate media feed to an end user at the output of the transmitter, the controller further programmed, based upon the at least one operating condition to selectively halt the media feed being made to the end user and thereafter supply a low-bit rate media feed to the end user at the output of the transmitter.

14. The device of claim 13 wherein the at least one operating condition is selected from a group comprising:

a Radio Frequency (RF) condition;

a system load condition, a battery life of a target mobile station;

a signal strength condition; and

a mobility condition.

15. The device of claim 13 wherein the low bit-rate media feed is a low-rate media feed.

16. The device of claim 13 wherein the low bit-rate media feed is selected from a group comprising:

a commercial advertisement;

a highlight video clip;

a replay video clip;

currently available music;

a slide;

a video XML stream having a lower bit rate;

a media having a less strict audio threshold;

a media having a less strict motion threshold;

a preloaded educational media; and

a media with a reduced amount of feature changes.

17. The device of claim 13 wherein the low bit-rate media feed is media from a play-out buffer having a reduced play-out rate.

18. The device of claim 13 further comprising means for selectively changing a source and rate of the high-rate media.

19. The device of claim 13 wherein the device is positioned at a location, the location being selected from a group comprising:

a media broadcaster;

a content server, within a radio Access Network (RAN); and

a mobile station.
