An example apparatus to generate media metering information includes a display to present selectable options for a user to select one of a plurality of levels of anonymity to be used in association with generating the media metering information indicative of media content presentations; a processor to access an anonymity selection of one of the levels of anonymity, the levels of anonymity including no anonymity, partial anonymity, and total anonymity; and a metering information generator to generate the media metering information in association with the anonymity selection.

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.

Disclosed example apparatus to determine volume of switching (VoS) among television programs examine first viewing data associated with a first time period and second viewing data associated with a second time period to identify a first set of panelists represented in both the first and second viewing data; in response to a size of the first set of panelists satisfying both first and second thresholds, estimate the VoS based on a first subset of the first viewing data and a second subset of the second viewing data associated with the first set of panelists; and in response to the size of the first set of panelists satisfying the first but not the second threshold, estimate the VoS based on the first and second subsets, and a third subset of the first viewing data and a fourth subset of the second viewing data associated with a second set of panelists.

Examples disclosed herein to estimate volume of switching (VoS) among television programs include determining, based on panelist program viewing data, a first VoS value representing a portion of a decreased amount of tuning by matched panelists to a first program from first to second measurement periods to attribute to an increased amount of tuning by the matched panelists to a second program from the first to second measurement periods; estimating, based on the program viewing data and first VoS value, a second VoS value representing a portion of a decreased amount of tuning by unmatched panelists to the first program from the first to second measurement periods to attribute to an increased amount of tuning by the unmatched panelists to the second program from the first to second measurement periods; and combining the first and second VoS values to determine a third VoS value for a combination of the matched and unmatched panelists.

A method for populating a plurality of radio stations on a user device, the method includes receiving the plurality of radio stations, including a radio station signal type, receiving a broadcast area for each of the plurality of radio stations, receiving a request for radio service from the user device, the request for radio service comprising a location of the user device, a user device signal threshold, and a user device antenna capability, wherein the user device antenna capability comprises at least one signal type, calculating a plurality of user device ranges for each of the plurality of radio stations, determining, a plurality of in-range radio stations, filtering, the plurality of in-range radio stations based at least in part on the user device signal threshold, further filtering the plurality of in-range radio stations based at least in part on the user device antenna capability, and transmitting the plurality of in-range radio stations, and related content for the each of the plurality of in-range radio stations.

A method is described for re-determining, in a television apparatus, a program table including associations between alphanumeric labels and radio-television programs, each one of the alphanumeric labels indicating a string of characters that must be selected by the user in order to activate the reproduction of one of the radio-television programs associated therewith, the method including the steps of biunivocally associating with each radio-television program in the table an alphanumeric label comprising a numeric part; allowing at least a first list and a second list to be simultaneously displayed on a screen, both including identification data of the radio-television programs obtained from the program table, the radio-television programs being sorted in the lists according to sorting criteria; selecting a first program from the first list of programs sorted according to a first sorting criterion, the first program being associated with a first alphanumeric label; selecting a second program from the second list of programs sorted according to a second sorting criterion, the second program being associated with a second alphanumeric label; and modifying the value of the first alphanumeric label of the first program with an alphanumeric label value comprised in the range delimited by the value of the second alphanumeric label, extreme included, and by the value of the alphanumeric label, extreme excluded, which immediately precedes the second alphanumeric label in the second list.

Small changes in a broadcast version of a base media item can be identified by performing a multi-level comparison of digital fingerprints. A fingerprint of a base media item is compared to a fingerprint of a media broadcast to determine whether a media item embedded in a broadcast is likely, to a first level of certainty, to be the base media item. A second, more stringent, match between the fingerprint of the base media item and loosely matched items can be used to identify potentially-altered versions of the base media item. Potentially-altered versions can be compared against each other, and resulting matches are flagged as altered base media items, which can be fingerprinted and tested against broadcast fingerprints in the same manner as the base media item.
