CODE EXECUTION IN COMPLEX AUDIOVISUAL EXPERIENCES

摘要

In one embodiment, a method includes obtaining a link to a video program; obtaining metadata that relates to the program and that defines, for a specified time point in the program, annotations to be invoked at the specified time point; wherein the annotations comprise: a graphic image; one or more filters, each of the filters comprising a key and one or more matching values; and optionally a reference to a video segment, an electronic document, program code statements, or a programmatic call; during playing the video, detecting that the video program is playing at the specified time point; in response to the detecting: for each particular annotation for the specified time point, retrieving a current value for the key, and causing to display the graphic image associated with that particular annotation only when the current value of the key matches one of the matching values of one of the filters.

主权项

1. A data processing method comprising:
at a computer, obtaining a link to a stored video program and obtaining metadata that relates to the video program and that defines, for a specified time point in the video program, one or more cue points or annotations to be processed at the specified time point; wherein one or more of the cue points or annotations identifies an executable action; causing the computer to play the video program from the link; during playing the video program on a computer, detecting that the video program is playing at the specified time point; in response to the detecting: for a first particular cue point associated with the specified time point, invoking the executable action; wherein the method is performed using one or more computing devices.
