Abstract: Methods and apparatus for detecting on-screen media sources are disclosed. An example method includes monitoring a region of interest of a video signal for a first image, comparing the first image to a stored image, and confirming the media device change when the stored image differs from the first image and is associated with a secondary criterion.

Abstract: Portable multi-purpose audience measurement systems, apparatus and methods are disclosed. An example method disclosed herein comprises collecting demographic data of a user, including a phone number for a mobile device, via a website associated with an information gathering entity, sending a message to the mobile device, the sent message, when responded to, resulting in downloading of a metering software module to the mobile device, receiving, from the mobile device and at a system associated with the information gathering entity, information indicative of events associated with use of the mobile device, and associating the received information with the demographic data.

Abstract: Methods and apparatus to determine audience viewing of video-on-demand programs are disclosed. An example method disclosed herein to monitor presentation of video-on-demand content comprises obtaining server metering data determined using a server metering device in communication with a video-on-demand server, the video-on-demand server to provide the video-on-demand content specifically to a first subscriber site among a plurality of subscriber sites, obtaining subscriber metering data corresponding to media content presented at the first subscriber site, the subscriber metering data determined using a site metering device different from the server metering device, and combining the subscriber metering data and the server metering data to monitor the video-on-demand content provided specifically to the first subscriber site.

Abstract: Methods and apparatus to collect publicly available metadata to determine media creation product usage are disclosed. Some example methods include collecting metadata from a plurality of digital media files, identifying product types used to generate the digital media files based on the metadata, determining which of the identified product types is used to generate a largest number of the digital media files, and generating a report identifying the product types used to generate the largest number of the digital media files.

Abstract: Methods and apparatus for identifying primary media content in a post-production media content presentation are disclosed. An example computer-implemented method to detect primary media content included in a secondary media content presentation disclosed herein comprises determining a first image corresponding to the secondary media content presentation, the first image comprising a plurality of image subregions, each image subregion representative of an inter-frame variation associated with a corresponding subregion of the secondary media content presentation, selecting a region of the first image comprising a plurality of connected image subregions of the first image together exhibiting a first type of inter-frame variation, and when a shape of the selected region of the first image corresponds to a predefined shape, processing a region of the first captured image corresponding to the selected region of the first synthetic image to identify the primary media content.

Abstract: Example methods and apparatus for associating media devices with a demographic composition of a geographic area are disclosed. A disclosed example method includes receiving a plurality of Internet Protocol addresses assigned to a media device associated with a panel member, determining a most used Internet Protocol address from the plurality of Internet Protocol addresses, accessing geographic information and determining a geographic location corresponding to the most used Internet Protocol address, accessing demographic information and determining a demographic profile associated with the geographic location, and associating at least one of the geographic location or the demographic profile with the media device.

Abstract: Portable multi-purpose audience measurement systems, apparatus and methods are disclosed. An example method to monitor a media presentation device disclosed herein comprises sensing a media content signal output by the media presentation device using a portable device separate from the media presentation device, the portable device supporting media metering functionality and native functionality, attempting to detect a code encoded in the sensed media content signal using the portable device, and generating a signature from the sensed media content signal using the portable device when the portable device is electrically coupled to an external power supply or the portable device has at least a threshold amount of local battery power, but not generating the signature when the portable device is not electrically coupled to the external power supply and the portable device does not have at least the threshold amount of local battery power.

Abstract: Methods and apparatus to detect a time-shift event associated with the presentation of media content are disclosed. A disclosed system generates a first metering event representative of a first time period in which a program was continuously presented and a second metering event representative of a second time period in which a program was continuously presented. A time-shift detector receives the first and second metering events and calculates a presentation gap value and a broadcast time jump value. The time-shift detector compares the presentation gap value and the broadcast time jump value to determine whether a pause event, a fast forward event or a rewind event occurred.

Abstract: As disclosed herein, media metering functionality may be imparted to a panelists device that was not previously capable of media metering. According to one example, a method of providing a communication device with media metering functionality includes asking a potential panelist to participate in a survey, receiving an affirmative response from the potential panelist, and providing metering functionality to a portable device of the potential panelist.

Abstract: Methods and apparatus to create a media measurement reference database from a plurality of distributed sources are described. An example method of developing a reference database associated with media content includes receiving first identifying data associated with media content from a meter on a first information presentation device, the media content being locally accessible at the first information presentation device; determining whether the reference database includes reference data associated with the first identifying data; when the reference database lacks the reference data associated with the first identifying data, sending a message to the meter requesting first reference data for the media content; and receiving the first reference data associated with the first identifying data.

Abstract: Methods and apparatus for cooperator installed meters are disclosed. An example method includes receiving audience information, configuring the audience meter based on the audience information, placing the audience meter in a sleep mode, and shipping the audience meter to a location associated with the audience information.

Abstract: Methods and apparatus for metering the presentation of computer-based media presentation are disclosed. An example disclosed method performed by a computer that is configured to execute an operating system and a media presentation program comprises modifying the media presentation program to re-direct a function call made to the operating system by the media presentation program, and processing the re-directed function call to determine media presentation information.

Abstract: Methods and apparatus for detecting on-screen media sources are disclosed. An example method includes monitoring a region of interest of a video signal for a first image, comparing the first image to a stored image, and confirming the media device change when the stored image differs from the first image and is associated with a secondary criterion.

Abstract: Method and apparatus for identifying broadcast digital audio signals include structure and/or function whereby the digital audio signal is provided to processing structure which is configured to (i) identify a program-identifying code in the received digital audio signal, (ii) identify a program-identifying code in a decompressed received digital audio signal, (iii) identify a feature signature in the received digital audio signal, and (iv) identify a feature signature in the decompressed received digital audio signal. Preferably, such processing structure is disposed in a dwelling or a monitoring site in an audience measurement system, such as the Nielsen TV ratings system.
