Abstract
Methods and apparatus to detect commercial advertisements associated with media presentations are disclosed. An example method involves receiving a video frame and detecting a change in box-formatting between the video frame and a subsequent video frame. A transition between the video frame and the subsequent video frame is indicated as a commercial advertisement transition based on the detected change in box-formatting.
Claims20
A system comprising:
- memory having stored therein machine-readable instructions;
- and
- one or more processors configured to execute the machine-readable instructions, wherein the machine-readable instructions cause, when executed by the one or more processors, the system to:
- obtain a sample of a television feed;
- construct, from the sample of the television feed, a plurality of audio frames;
- monitor the plurality of audio frames by, for each audio frame of the plurality of audio frames:
- (i) evaluating an audio power level of the audio frame;
- (ii) comparing the evaluated audio power level with a first audio-level threshold, and (iii) comparing the evaluated audio power level with a second audio-level threshold;
- identify, based on monitoring the plurality of audio frames, a particular one of the plurality of audio frames having an audio power level below the first audio-level threshold;
- and
- indicate a commercial transition within the television feed at a timing corresponding to the particular one of the plurality of audio frames.

A non-transitory computer-readable storage medium having stored thereon machine-readable instructions that, when executed by a processor of a computing system, cause performance of operations including:
- obtaining a sample of a television feed;
- constructing, from the sample of the television feed, a plurality of audio frames;
- monitoring the plurality of audio frames by, for each audio frame of the plurality of audio frames:
- (i) evaluating an audio power level of the audio frame;
- (ii) comparing the evaluated audio power level with a first audio-level threshold, and (iii) comparing the evaluated audio power level with a second audio-level threshold;
- identifying, based on monitoring the plurality of audio frames, a particular one of the plurality of audio frames having an audio power level below the first audio-level threshold;
- and
- indicating a commercial transition within the television feed at a timing corresponding to the particular one of the plurality of audio frames.
