International Classification:

H04N 21/80

US Classification:

725 32

Abstract:

In a streaming video system, a method determining a sequence of video programs playing on an interactive player device may include streaming a first video program including an ad break from a computer server to an interactive player device during a first streaming session. The method may further include automatically selecting a video advertisement or next program from a set of prospective video advertisements for play during the ad break or available programs, based at least in part on the first video program exclusive of any parameter based on user identity. The method may include providing the video advertisement to the interactive player device in the first streaming session at the ad break. Bases for selecting the next ad or program may include program popularity, rate of change in popularity, or other parameter. The method may be embodied in a computing apparatus or system.

US Classification:

707748, 707758

Abstract:

A method and apparatus for recommending a media program of a set of media programs to a user of a set of users is disclosed. The method and apparatus computes a measure wof the implied similarity of a first media program (i) and a second media program (j) that corrects for the popularity of the media programs, thus resulting in a more accurate indication of the relatedness of the media programs.

Abstract:

In one embodiment, a method separates subscriber features generated from subscriber interaction with a video delivery service into feature dimensions and inputs the feature dimensions into a respective prediction network. Each prediction network is trained to output a respective dimension score. The method outputs dimension scores using parameters in the plurality of prediction networks that are trained using a variance term to control a variance of the plurality of feature dimensions and using a de-correlation term to control a correlation of the plurality of feature dimensions. The dimension scores are combined into a retention prediction score and an action is performed on the video delivery service for the subscriber based on the retention score.
