摘要： 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.

摘要： 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.

摘要： 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.
