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.

Methods, apparatus, systems and articles of manufacture to reduce false positive signature matches due to similar media segments in different reference media assets are disclosed. Example apparatus disclosed herein include a signature matcher to compare monitored media signatures with a library of reference media signatures, the monitored media signatures associated with monitored media, the library of reference media signatures including sequences of reference signatures associated with respective reference media assets. Disclosed example apparatus also include a match information identifier to identify a number of different matched reference media assets associated with ones of the sequences of reference media signatures that match a sequence of matched monitored media signatures. Disclosed example apparatus further include a false positive identifier to, in response to the number of different matched reference media assets satisfying a threshold number, eliminate one or more of the matched reference media assets from being credited to the monitored media.

Measuring and tracking user interaction with a television receiver, such as a set top box or cable box. The television receiver may create and display a matrix code that includes temporal information, user identification information, geographic information, and/or a user selection. The matrix code may be captured by a matrix reading device and transmitted to a monitoring entity. Optionally, the matrix reading device may decode the matrix code and transmit associated data to the monitoring entity. The monitoring entity may use the code or data to track and distinguish between user interactions at different points in time.

An example apparatus to monitor media that is presented via a mobile device includes: an application monitor to determine when media presentation software is being executed by the mobile device; and a metering information collector to collect at least one of a signature or a code of the media presented by the media presentation software based on the media presentation software being executed by the mobile device.

A detection device detecting a scene related to a sponsor credit included in a commercial message from a target video is provided. The detection device comprises a detection unit that associates, from a preliminary video, a still image related to the sponsor credit with an audio signal related to the sponsor credit included other than in a frame or an audio signal configuring the commercial message so as to detect the scene related to the sponsor credit from the target video.

Methods, apparatus, systems and articles of manufacture are disclosed to monitor a split screen media presentation. Example apparatus disclosed herein are to generate one or more video signatures associated with video output from a media device and determine whether the one or more video signatures correspond to first media identified based on audio output from the media device. Disclosed example apparatus are also to, in response to a determination that the one or more generated video signatures do not correspond to the first media, determine that the video corresponds to a split-screen presentation having a plurality of regions-of-interest, and identify a first one of the regions-of-interest of the split-screen presentation that includes the first media.
