Abstract: In a networked system connecting a subscriber to a content source via one or more networks, a computer-implemented method includes instantiating a session model for a media session between the subscriber and the content source, the session model to generate session metadata from application-layer interactions between the subscriber and the content source. The method further includes instantiating an interaction model in response to detecting an application-layer interaction in a transport flow of the subscriber, the application-layer interaction comprising media data for the media session. The method also includes generating, at the interaction model, interaction metadata representative of the application-layer interaction, and processing at least one of the interaction metadata and the media data at the session model to generate session metadata responsive to matching the interaction model to the session model.

Abstract: An apparatus generally having an interface and a circuit is disclosed. The interface may be connectable to a network to monitor a media program streaming across the network to a media client. The circuit may be configured to (i) generate first information by modeling a buffer of the media client, the first information being representative of a plurality of events related to the buffer during a playback of the media program and (ii) generate a signal representative of a quality of experience of the media program in response to the first information.

Abstract: Apparatus, methods and systems using no-reference techniques for computing quality scores for audio and video components of a media session, where the quality scores are estimates of perceived quality by the viewer for the individual components of the media session. A presentation quality score is computed for a media stream by parsing a container of the media stream to determine media stream characteristics, estimating an visual quality factor and based on the visual quality factor, determining the presentation quality score.

Abstract: A method for enabling streaming to a media player without native streaming support is disclosed. Step (A) of the method may author a media file based on a content signal. The media file may have an indexed format compatible with the media player. The content signal may (i) be received from a remote server through a network, (ii) use a transfer protocol and format at least one of which is incompatible with the media player and (iii) convey both video data and audio data representative of a scene. Step (B) may generate a local signal carrying the media file. The local signal generally has a transfer protocol compatible with the media player. Step (C) may transfer the local signal to the media player while the content signal is being received. The media player generally recreates the video data as a visual depiction on a display based on the local signal.

Abstract: Methods and systems for controlling quality of a media stream in a media session. The described methods and system control the quality of the media stream by controlling transcoding of the media session. The transcoding is controlled at the commencement of the media session and dynamically during the life of the media session. The transcoding is controlled by selecting a target quality of experience (QoE) for the media session, computing a predicted QoE for each of a plurality of control points, where each control point has a plurality of transcoding parameters associated therewith, selecting an control point of the plurality of control points, wherein the predicted QoE for the selected control point substantially corresponds with the target QoE and signaling the transcoder to use the selected control point for the media session.
