Abstract:
A method of enabling transmission of a data service from a content server to a terminal using a data channel in a system in which at least part of the data service is transmitted to the terminal using a broadcast channel, the method including: receiving, using the broadcast channel, first data comprising part of the data service; processing the first data using a signature-generating algorithm to derive first signature data; transmitting the first signature data using the data channel to the content server; validating the first signature data by comparing said first signature data with a signature derived by processing data comprising part of the data service using a corresponding signature-generating algorithm; and enabling the terminal to access the data service using the data channel dependent on validation of the first signature data.
Abstract:
Example methods disclosed herein to identify media sources include determining whether a first time difference between a first meter signature and a second meter signature associated with presented media is equivalent to a second time difference between a first reference signature determined to match the first meter signature and a second reference signature determined to match the second meter signature, the first and second reference signatures being associated with a first one of a plurality of media sources. Such example methods also include, in response to determining that the first time difference and the second time difference are equivalent, appending the second reference signature to a first tracking segment associated with the first one of the media sources to cause a first time length associated with the first tracking segment to be increased based on at least a respective timestamp associated with the second reference signature.
Abstract:
A method and system for searching a plurality of information sources using a multimedia content element are provided. The method comprises receiving an input search query including the multimedia content element and at least one on-image gesture detected thereon; generating at least one signature for the multimedia content element; analyzing the at least one on-image gesture to determine at least one portion of the multimedia content element in which a user is interested; generating at least one signature for each of the at least one portion of the multimedia content element; generating a textual search query using the at least the one generated signature; searching the plurality of information sources using the generated textual search query; and causing the display of search results retrieved from the plurality of information sources on a user device.
Abstract:
Technologies are disclosed for enabling users to comprehensively determine their exposures to media and to receive services based thereon. For example, an application can be executed on a computing device associated with a user. The application can continuously monitor audio data that the computing device is exposed to and can generate digital signatures thereof. The digital signatures can be transmitted to a server that comprises a database of reference digital signatures and circuitry configured to compare and match the received digital signatures and the reference digital signatures. When a match is found, the server retrieves information associated with the matched reference digital signature and returns, to the device, the retrieved information. The server can also concatenate matches associated with data received from a plurality of computing devices and provide the concatenated data to a third party, who in turn, returns services to the users based on the received data.
Abstract:
A method for conducting search-by-content is provided. The method includes responsive to an input multimedia content item provided to a user device, checking if the input multimedia content item matches at least one concept of a plurality of concepts cached in the user device; retrieving characteristics set for a user of the user device; performing a search, using the at least one matching concept, for multimedia content items similar to the input multimedia content item; determining which of the search results are of interest to the user based on the characteristics set for the user; and saving results that are of interest to the user in the user device, wherein the saved results include multimedia content items.
Abstract:
Methods and apparatus to adaptively gather audience information data are disclosed. The disclosed methods and apparatus monitor system factor(s) and select one or more sensors from a plurality of sensors positioned to gather audience measurement data based on the monitored factor(s). Thus, the disclosed methods and apparatus adapt to the conditions they face by selecting an amount and/or type of audience measurement data they gather.
Abstract:
Methods and apparatus to control a state of data collection devices are disclosed. An example method includes generating a level of engagement based on an analysis of an audience associated with a media exposure environment; and controlling a state of a data collection device based on the level of engagement.
Abstract:
Apparatus, methods and articles of manufacture for determining an operating mode of a recording/playing device are disclosed. An example apparatus includes an extractor to extract signatures associated with a first signal associated with a tuner that is to tune to a program signal, a second signal associated with a recording/playing device that is to at least one of record and play a program, and a third signal associated with a receiver coupled to the recording/playing device. The example apparatus also includes a recording detector to detect a recording signal generated by the recording/playing device during recording of the program to form a recorded program. Also included is a correlator to correlate the first, second, and third signals and a processor to identify the operating mode of the recording/playing device based on detection of the recording signal and correlation of two or more of the first, second, and third signals.
Abstract:
This method for identifying a video programme received by a user (UE), by identifying an audio sequence contained within that video programme, consists of; receiving (1-6) a plurality of reference audio sequences, and receiving, for each of those sequences, a signature and a reference audio signature identifier, —preselecting (8) a series of reference audio signature identifiers, then correlating (9) the signatures respectively corresponding to these preselected identifiers, with a signature representing an audio sequence contained within the video programme received by the user, and selecting from among the preselected identifiers the one which exhibits the greatest correlation, in order to identify an audio sequence, and thereby to identify the video programme received by the user; In order to preselect a series of reference audio signature identifiers, it consists of particularly taking into account information describing the video programme received by the user, which is provided by a programme guide that is distributed in parallel with the is video programmes to be identified.
Abstract:
Apparatus, system and method for accessing supplementary data and/or executing software on a device capable of receiving multimedia are disclosed. After multimedia is received, ancillary code is detected and a signature is concurrently extracted from an audio portion of the multimedia. The ancillary code includes a plurality of code symbols arranged in a plurality of layers in a predetermined time period, and the signature is extracted from features of the audio of the multimedia. Supplementary data is accessed and/or software is executed using the detected code an/or signature.
