20110246202 | METHODS AND APPARATUS FOR AUDIO WATERMARKING A SUBSTANTIALLY SILENT MEDIA CONTENT PRESENTATION - Methods and apparatus for audio watermarking a substantially silent media content presentation are disclosed. An example method to audio watermark a media content presentation disclosed herein comprises obtaining a watermarked noise signal comprising a watermark and a noise signal having energy substantially concentrated in an audible frequency band, the watermarked noise signal attenuated to be substantially inaudible without combining with a separate audio signal, associating the watermarked noise signal with a substantially silent content component of the media content presentation, the media content presentation comprising one or more media content components, and outputting the watermarked noise signal during presentation of the substantially silent content component. | 10-06-2011 |
20130007790 | PROGRAM TELECAST MONITORING USING WATERMARKS - Methods, apparatus and articles of manufacture for program telecast monitoring using watermarks are disclosed. An example method for program monitoring disclosed herein comprises obtaining a sequence of watermarks detected from a presentation of media content at a monitored site, and comparing a data pattern obtained from the sequence of watermarks with a set of possible data patterns to identify a particular program transmission of the media content, the set of possible data patterns being associated respectively with a set of possible transmissions of the media content. An example method to watermark media content disclosed herein comprises encoding the media content with a sequence of watermarks, a watermark in the sequence of watermarks including content identifying payload data, and modifying the sequence of watermarks to also include a data pattern associated with a particular transmission of the media content. | 01-03-2013 |
20130103172 | METHODS AND APPARATUS FOR AUDIO WATERMARKING A SUBSTANTIALLY SILENT MEDIA CONTENT PRESENTATION - Methods and apparatus for audio watermarking a substantially silent media content presentation are disclosed. An example method to audio watermark a media content presentation disclosed herein comprises obtaining a watermarked noise signal comprising a watermark and a noise signal having energy substantially concentrated in an audible frequency band, the watermarked noise signal attenuated to be substantially inaudible without combining with a separate audio signal, associating the watermarked noise signal with a substantially silent content component of the media content presentation, the media content presentation comprising one or more media content components, and outputting the watermarked noise signal during presentation of the substantially silent content component. | 04-25-2013 |
20130251189 | MEDIA MONITORING USING MULTIPLE TYPES OF SIGNATURES - Media monitoring using multiple types of signatures is disclosed. An example media monitoring method disclosed herein comprises processing signatures of a first type to monitor media presented by a media device until a first one of the signatures of the first type is determined to match a reference signature of the first type, the reference signature of the first type being associated with first reference media, and processing signatures of a second type to monitor the media presented by the media device after the first one of the signatures of the first type is determined to match the reference signature of the first type and until a number of signatures of the second type is determined not to match corresponding reference signatures of the second type, the reference signatures of the second type being associated with the first reference media. | 09-26-2013 |
20140033246 | PROGRAM TELECAST MONITORING USING WATERMARKS - Methods, apparatus and articles of manufacture for program telecast monitoring using watermarks are disclosed. Example methods disclosed herein to watermark media can include encoding the media with a sequence of watermarks, a watermark in the sequence of watermarks including payload data identifying the media. Such example methods can also include, modifying the sequence of watermarks to further include a data pattern associated with a particular transmission of the media. In some examples, respective watermarks in the sequence of watermarks are to be modified to include respective portions of the data pattern, wherein the respective portions, when combined, form the data pattern. | 01-30-2014 |
20140280888 | Methods, Apparatus and Articles of Manufacture to Monitor Media Devices - Methods, apparatus, systems and articles of manufacture to monitor media devices are disclosed. An example method includes causing a removable storage device to store an identifier associated with a panelist, the removable storage device having a part to be removably coupled to a data port of a media device; providing the removable storage device to the panelist; and providing an application to be executed by the media device with a first instruction to, in response to the application detecting an event associated with the application, retrieve the identifier from the data port of the media device executing the application. | 09-18-2014 |
20140289755 | MEDIA MONITORING USING MULTIPLE TYPES OF SIGNATURES - Media monitoring using multiple types of signatures is disclosed. Example media monitoring methods disclosed herein include reporting media signatures of a first type to monitor media presented by a media device, the media signatures of the first type being generated by a device meter from a sensed signal. Disclosed example media monitoring methods also include, after receiving an indication that a first media signature of the first type is associated with first reference media, generating media signatures of a second type, different from the first type, from the sensed signal to continue monitoring the media presented by the media device. Disclosed example media monitoring methods further include, in response to detecting that a source of the media presented by the media device has changed, generating the media signatures of the first type to continue monitoring the media presented by the media device. | 09-25-2014 |
20150052245 | Methods, Apparatus and Articles of Manufacture to Monitor Media Devices - Methods, apparatus, systems and articles of manufacture to monitor media devices are disclosed. An example media device includes a data port to receive a removable storage device; and an application instrumented to obtain first data associated with a monitoring event of the application; reference the data port to retrieve a panelist identifier from the removable storage device in response to the monitoring event; and convey the first data and the panelist identifier to a remote computer. | 02-19-2015 |
