Method and system for altering the presentation of broadcast content

摘要

Embodiments of the present invention are directed to a method and system for altering a presentation of broadcast content. More specifically, embodiments provide an accurate and efficient mechanism for suppressing advertisements by using downloaded templates to identify advertisements before suppression for a duration indicated by information downloaded about the advertisement, where the suppression is effectuated by controlling a display or set-top box using remote-control functionality. In one embodiment, a digital signal comprising broadcast content is accessed. A plurality of templates are received and stored, wherein each template represents a known portion of the broadcast content. The digital signal is then compared against a portion of the plurality of stored templates. Upon a match, a control signal operable to alter a component of a presentation of the known portion of the broadcast content is generated.

主权项

1. A system comprising:
at least one non-transitory computer readable storage medium with instructions executable by at least one processor to: access a digital signal including audio video content: access a plurality of test data structures; compare, plural times, the digital signal with at least some of the test data structures; and generate a control signal responsive to a match of at least a portion of the digital signal with at least a portion of the test data structures, wherein the control signal is operable to alter a component of a presentation of the portion of the broadcast content, wherein a length of an interval between comparisons of the digital signal to the test data structures is a first length for a first period commencing with a match of at least a portion of the digital signal with at least a portion of the test data structures, the first period ending at a first time, the length of the interval between comparisons of the digital signal to the test data structures being shortened to a second length shorter than the first length upon the elapse of the first period.
