Playback adjustments for digital media items

摘要

An adjustment module analyzes user adjustments in a playback attribute (e.g., volume) of a media item (e.g., a video) that occur when the user transitions from one media item to another. By analyzing these adjustments, the adjustment module determines an adjustment amount to apply to the playback attribute of a media item to cause the media item to appear equivalent to users with respect to the playback attribute when compared with the media item that was previously played.

1. A computer-implemented method comprising:
identifying transitions in playing videos, a transition from a first video to a second video representing playing the second video directly following playing the first video; for each identified transition:
determining a first level of volume at which the first video of the transition was played;determining a second level of volume at which the second video of the transition was played; anddetermining an amount of user volume adjustment a user has applied based on the first level of volume and the second level of volume; identifying a set of videos involved in at least one of the identified transitions; for a subset of the videos of the set, forming a graph in which:
each vertex represents a video of the subset of videos, andeach edge between a pair of vertices represents a degree of confidence in a corresponding amount of user volume adjustment determined for an identified transition from a video corresponding to one of the vertices in the pair and another video corresponding to the other vertex in the pair; forming a spanning tree connecting the subset of videos; and for a given pair of videos of the subset of videos where no transition was identified between the pair:
determining, using the spanning tree, an automatic playback adjustment amount by which to adjust a volume level of one video of the pair in order to cause an effective volume level of the video when played to appear equivalent to an effective volume level of the other video when played.
