A system and method for determining driving decisions based on multimedia content. The method includes obtaining, in real-time during a trip of a vehicle, trip multimedia content elements captured by at least one sensor deployed in proximity to the vehicle; identifying, based on at least one signature generated for each trip multimedia content element, at least one matching event multimedia content element, wherein each event multimedia content element demonstrates an event and is associated with a corresponding driving decision; and determining, in real-time, at least one driving decision, wherein each determined driving decision is associated with one of the identified at least one event multimedia content element.

A system and method for searching based on input multimedia content elements. The method includes obtaining at least one signature for each of at least one input multimedia content element, each signature representing a concept, wherein each concept is a collection of signatures and metadata representing the concept; determining, based on the obtained signatures, at least one context of the at least one input multimedia content element; generating, based on the determined at least one context, at least one query; and searching in at least one data source using the generated at least one query.

A system and method for identifying trending content based on context. The method includes generating at least one signature for each of a plurality of multimedia content elements, wherein each signature represents a concept, wherein each concept is a collection of signatures and metadata describing the concept; correlating the concepts of the generated signatures to determine at least one context of each multimedia content element, wherein each context represents a sentiment; and identifying, based on the determined contexts, at least one trending multimedia content element, wherein the context of each trending multimedia content element meets a sentiment threshold.

System for determining the efficiency of publicity and/or broadcasted programs, comprising an audio signature generating unit with an adaptor that consists of a sampling unit for sampling the audio signal transmitted by the radio/TV at a first rate; a transformer, for obtaining galvanic separation between the power amplifier of the radio/TV, which feeds the loudspeakers and the input to the sampling circuitry. The audio signature generating unit is adapted to sample the audio signal transmitted by the receiver radio/TV that receives FM-radio/TV stations and to generate a characteristic audio signature. The system also comprises a plurality of stationary reference station units, each continuously listens to a station and is adapted to sample the audio signal transmitted by a particular broadcasting station to generate a stationary characteristic audio signature. A server is used to receive all signatures and continuously compare each characteristic audio signature to all stationary characteristic audio signatures, in order to find the best matching to one of the stationary characteristic audio signatures. If consecutive samples received from the audio signature generating unit appear essentially at the same timing within a predetermined time window, the server determines that the radio/TV receiver of a particular audio signature generating unit is currently tuned to a corresponding broadcasting station, for which the best matching has been found.

A method may comprise collecting data from a core network, an operator network and a customer premise network. KPI values corresponding to one or more KPIs may be determined, based on the collected data. KQI values corresponding to one or more KQIs may be determined, based on the one or more of the determined KPI values. The determined KQI values may be output to an operator. In an embodiment, data collected from the core network may include data collected from one or more analyzer devices and head end probes. Data collected from a customer premise network may include data collected from last mile equipment or customer premise probes.

A facility for generating analytical information based on individual reports of multiple scheduled presentations of interstitial media assets is provided. Data files are received, each including multiple status reports regarding multiple scheduled presentations of multiple media assets by a plurality of distinct media receiver devices in multiple disparate locations. The data files are decrypted, such that the decrypted one or more data files include, for each of the multiple status reports, at least a media asset identifier and a presentation status indicator, and parsed to generate one or more database entries containing information regarding the scheduled media presentations and the plurality of distinct media receiver devices. One or more user interfaces are provided to allow execution of queries based on the generated one or more databases.

Methods, apparatus, systems and articles of manufacture are disclosed to estimate an audience population. An apparatus includes a characteristic identifier to determine whether respective ones of respondents are associated with a characteristic, a respondent identifier to determine whether the respective ones of the respondents are recaptured based on a comparison of a person identifier corresponding to respondents and a database of previously identified person identifiers, a count determiner to, in response to the respective ones of the respondents exhibiting the characteristic, increase a total capture count by one and, in response to detecting unique instances of the respective ones of the respondents exhibiting the characteristic, increase a unique capture count by one, and a population estimator to, in response to a recapture probability satisfying a threshold, determine a population estimate having the characteristic based on the total capture count, the unique capture count, and a number of available samples.

Methods and apparatus to generate audience measurement data from population sample data having incomplete demographic classifications are disclosed. An example method includes detecting that a number of impressions a time segment of a video occurred based on messages; detecting that no impressions for the time segment of the video were detected by the database proprietor; determining respective percentages of exposures of the video that are attributable to corresponding ones of multiple demographic groups, determining the respective percentages being based on the first demographic information provided by the database proprietor for exposures of other time segments of the video; attributing respective portions of the number of impressions to the demographic groups based on the respective percentages to determine imputed numbers of impressions; generating adjusted numbers of impressions based on the imputed numbers of impressions; and determining ratings information for the video using the adjusted numbers of impressions.
