Abstract

A user'"'"'s content presentation device automatically measures the technical objective quality of an Internet video stream and/or estimates the perceived subjective quality of the stream, and provides feedback to the user regarding one or both of these estimates.

Claims

1. A content presentation device, comprising:

at least one processor;

at least one Internet interface configured to receive audio/video signals from the Internet; and

at least one monitor for presenting audio/video, wherein

the processor determines a quality of service (QoS) and/or quality of experience (QoE) for signals from at least one Web site on the Internet and causes an indication of the QoS and/or QoE to be presented on the monitor along with an indication of the associated Web site.

2. The content presentation device of claim 1, wherein the QoS is determined based at least in part on packet error rates (PER) and/or packet jitter and/or packet round-trip times (RTT) and/or streaming protocol and/or video codec and/or source content bit-rate.

3. The content presentation device of claim 2, wherein QoS is directly proportional to the source bit rates and is inversely proportional to PER, packet jitter, and packet RTT.

4. The content presentation device of claim 3, wherein the content presentation device includes a video decoder and a dejitter buffer, and QoS is measured on signals input to the video decoder after the de-jitter buffer.

5. The content presentation device of claim 1, wherein QoS is used to derive a QoE, the QoE modifying QoS to account for at least one device-specific parameter, an indication of QoE being presented on the monitor.

6. The content presentation device of claim 5, wherein the parameter includes error concealment.

7. The content presentation device of claim 5, wherein the parameter includes content presentation capabilities of the monitor.

8. The content presentation device of claim 1, further comprising a TV tuner.

9. A method for presenting a user with an indication of quality of video received from plural Web sites, comprising:

for each Web site, determining at least a QoS and/or QoE representing the quality of video from the Web site; and

presenting a graphical user interface (GUI) on a monitor listing the Web sites along with corresponding indications of QoS/QoE associated therewith.

10. The method of claim 9, comprising:

determining QoS based at least in part on packet error rates (PER) and/or packet jitter and/or packet round-trip times (RTT) and/or streaming protocol and/or video codec and/or source content bit-rate.

11. The method of claim 10, wherein QoS is directly proportional to the source bit rates and is inversely proportional to PER, packet jitter, and packet RTT.

12. The method of claim 9, comprising measuring QoS on signals input to a video decoder after a de-jitter buffer.

13. The method of claim 9, wherein QoS is used to derive a QoE, the QoE modifying QoS to account for at least one device-specific parameter.

14. The method of claim 13, wherein the parameter includes error concealment.

15. The method of claim 13, wherein the parameter includes content presentation capabilities of the monitor.

16. A system comprising:

means for digitally processing signals;

means for displaying video streams;

means for receiving Internet signals; and

logic means executable by the means for digitally processing for causing the means for displaying to display sources of Internet signals in a first column and indications of signal quality from the sources in a second column juxtaposed with the first column.

17. The system of claim 16, wherein means for digitally processing includes a processor, the means for digitally displaying includes a monitor, and the logic means are embodied on a computer readable medium.

18. The system of claim 17, wherein the indications of signal quality represent QoS that is directly proportional to the source bit rates and is inversely proportional to PER, packet jitter, and packet RTT.

19. The system of claim 17, wherein the indications of signal quality represent a QoE accounting for error concealment and/or content presentation capabilities of the monitor.

20. The system of claim 16, comprising a TV tuner.
