Abstract

Embodiments of the present disclosure describe devices, methods, computer-readable media and systems configurations for monitoring and reporting quality of experience (QoE) metrics that are associated with an access method. Other embodiments may be described and claimed.

First claim

What is claimed is:

1. One or more non-transitory computer readable media having instructions that, when executed, cause a dynamic adaptive streaming over hypertext transfer protocol (DASH) client on a user equipment (UE) to:
download, by a processor of the UE, segments of a media stream from a server, the segments being DASH segments provided to the DASH client by a unicast access method or a broadcast access method, the segments to be received at the UE by a transceiver of a network interface and placed in memory of the UE;
record, in the memory of the UE while monitoring download and playback of the segments of the media stream, a quality of experience (QoE) metric related to playback of the segments of the media stream, wherein the QoE metric includes an indication of a switch to the unicast access method or the broadcast access method; and
transmit, from the UE using the transceiver of the network interface, the QoE metric to a QoE reporting server,
wherein the QoE metric comprises a playlist metric to log a list of playlist elements for one or more playback periods in a measurement interval and the list of playlist elements includes a stop-reason parameter that includes the indication of the switch as a reason why a continuous presentation of a representation of the media stream was stopped.

2. The one or more non-transitory computer-readable media of claim 1 , wherein the broadcast access method is a multimedia broadcast/multicast service (MBMS) or file delivery over unidirectional transport (FLUTE)-based access method and the unicast access method is a hypertext transfer protocol (HTTP)-based access method.

3. The one or more non-transitory computer-readable media of claim 1 , wherein the instructions, when executed, further cause the DASH client to:
obtain a reporting trigger in a media presentation description (MPD), an open mobile alliance (OMA) device management (DM) QoE management object, or in a session description protocol (SDP) message; and

transmit the QoE metric based on the reporting trigger.

4. An apparatus comprising:
a media player having a processor to download segments of a media stream from a server, the segments provided by a unicast access method or a broadcast access method;
a quality of experience (QoE) monitoring module coupled to the media player, the QoE monitoring module to:
record, in memory of the apparatus while monitoring download and playback the segments of the media stream, a QoE metric related to the playback of the segments of the media stream, wherein the QoE metric includes an indication of a switch to the unicast access method or the broadcast access method; and
transmit the QoE metric to a QoE reporting server,
wherein the QoE metric comprises a playlist metric to log a list of playlist elements for one or more playback periods in a measurement interval and the list of playlist elements includes a stop-reason parameter that includes the indication of the switch as a reason why a continuous presentation of a representation of the media stream was stopped.

5. The apparatus of claim 4 , wherein the broadcast access method is a multimedia broadcast/multicast service (MBMS) or file delivery over unidirectional transport (FLUTE)-based access method and the unicast access method is a hypertext transfer protocol (HTTP)-based access method.

6. The apparatus of claim 4 , wherein the QoE monitoring module is to:
obtain a reporting trigger in a media presentation description (MPD), an open mobile alliance (OMA) device management (DM) QoE management object, or in a session description protocol (SDP) message; and
transmit the QoE metric based on the reporting trigger.

7. The apparatus of claim 4 , further comprising:
a touchscreen display,
wherein the media player is to render the media stream on the touchscreen display.

8. The apparatus of claim 4 , wherein the media player is to:
receive a first portion of the media stream via the unicast access method; and
receive a second portion of the media stream via the broadcast access method.

9. A method comprising:
downloading, by a processor of a user equipment, segments of a media stream from a server, the segments provided to a dynamic adaptive streaming over hypertext transfer protocol (DASH) client by a unicast access method or a broadcast access method;
recording, in memory of the user equipment, while monitoring download and playback of the segments, a quality of experience (QoE) metric related to the playback of the segments of the media stream, wherein the QoE metric includes an indication of a switch to the unicast access method or the broadcast access method; and
transmitting, by the user equipment, the QoE metric to a QoE reporting server,
wherein the QoE metric comprises a playlist metric to log a list of playlist elements for one or more playback periods in a measurement interval and the list of playlist elements includes a stop-reason parameter that includes the indication of the switch as a reason why a continuous presentation of a representation of the media stream was stopped.

10. The method of claim 9 , wherein the broadcast access method is a multimedia broadcast/multicast service (MBMS) or file delivery over unidirectional transport (FLUTE)-based access method and the unicast access method is a hypertext transfer protocol (HTTP)-based access method.

11. The method of claim 9 , further comprising:
receiving a reporting trigger in a media presentation description (MPD), an open mobile alliance (OMA) device management (DM) QoE management object, or in a session description protocol (SDP) message; and
transmitting the QoE metric based on the reporting trigger.

12. The method of claim 9 , further comprising:
receiving a first portion of the media stream via the unicast access method; and
receiving a second portion of the media stream via the broadcast access method.
