Abstract:
Methods of gathering data concerning a location of an audience member proximate to a content presentation are provided. A stationary device is proximate to the content presentation. A portable monitor is carried by or with the person of an audience member. Location data is obtained by communicating data from the portable monitor to the stationary device, or from the stationary device to the portable monitor, or by comparing data gathered by both the stationary device and the portable monitor.
Abstract:
The method of content identification consists of creating a signature to comprise one or more sub-signatures. A sub-signature is created by averaging values of a feature in multiple frames of a content item (24). The electronics device (62) is able to retrieve a first signature of a first content item from a storage means (66) and to receive a second content item using a receiver (68). The device has a control unit (70) which is able to create one or more sub- signatures by averaging values of one or more features in multiple frames of the second content item and using the one or more sub-signatures to create a second signature. The control unit (70) is also able to determine similarity between the two signatures by determining similarity of sub-signatures for a similar feature. The software is able to create a signature for a content item by averaging values of a feature in multiple frames in a sequence of frames in the content item.
Abstract:
해시들은 데이터 파일을 식별하기 위해 사용될 수 있는 데이터 파일들의 짧은 써머리들(summaries) 또는 시그네쳐들이다. 다중매체 콘텐트(오디오, 비디오, 이미지)를 해싱하는 것은 원래 콘텐트 및 처리된(예컨대, 압축된) 콘텐트의 해시가 상당히 다를 수 있으므로 곤란하다. 개시된 방법은 예컨대 오디오 클립들과 같은 다중매체 콘텐트에 대한 튼튼한 해시들을 생성한다. 오디오 클립은 연속적인(바람직하게는 오버랩하는) 프레임들로 분할된다(12). 각각의 프레임에 대해, 주파수 스펙트럼은 밴드들로 분할된다(15). 각 밴드의 튼튼한 특성(예컨대, 에너지)이 계산되고(16) 각각의 해시 비트에 의해 표현된다(17). 따라서, 오디오 클립은 2진수 해시 워드들의 연결로써 나타내지고, 하나의 해시 워드는 하나의 프레임에 가능하게 압축된 오디오 신호를 식별하기 위해서, 그로부터 도출된 해시 워드들의 블록은, 컴퓨터(20)에 의해 큰 데이터베이스(21)에 매칭된다. 또한, 각각의 매칭 방법들이 설명된다. 바람직한 실시예에서, 또한 추출 과정은 해시 비트들 중 어떤 것이 가장 신뢰할 수 없는 것인지에 대해 정보(19)를 제공한다. 이들 비트들을 플리핑(flipping)하는 것은 매칭 과정의 속도 및 성능을 상당히 향상시킨다.
Abstract:
Portable People Meter (PPM) to collect metering information associated with multimedia data played back by a multimedia presentation device such as mobile digital assistant MDA, portable computer, mobile telephone or other. A wireless headset or earpiece is coupled to the multimedia presentation device via Bluetooth®, and the speaker of the headset emits audio based on the multimedia data received from the presentation device. The PPM includes a metering information generator eavesdropping, on the digital wireless interface of the headset, the audio information from the media presentation device to generate audience metering information associated with the audio data. The implementation of the PPM includes microcode executed on a general purpose processor.
Abstract:
Example methods, apparatus, systems, and articles of manufacture meter media content presented on a wireless communication device are disclosed. A disclosed example method receives media content via a wireless communication device. The media content is to be presented via the wireless communication device. First information is generated indicative of a media presentation mode of a media presentation application executed by the wireless communication device to present the media content. Second information is generated indicative of the media content presented via the wireless communication device. The first information is stored in association with the second information in the wireless communication device.
Abstract:
Methods, apparatus, and articles of manufacture for reducing spillover in a media monitoring system are disclosed. An example method includes identifying media associated with media monitoring data. The media monitoring data is received from a first meter associated with a first media presentation device. The example method includes identifying an expected sound pressure level associated with the first meter. The example method includes comparing the expected sound pressure level to an actual sound pressure level collected from the media by the first meter to determine if spillover occurred. The example method includes crediting the media as a media exposure if spillover did not occur.
Abstract:
Provided is a reception device including a reception part configured to receive first content, a feature amount extraction part configured to extract a feature amount from data of the received first content, an identification result acquisition part configured to acquire an identification result for the first content identified using the extracted feature amount, a command acquisition part configured to acquire a command for controlling an operation of changing over between the first content and second content different from the first content depending on the acquired identification result, and a control part configured to control an operation of changing over from the first content to the second content in response to the acquired command.
Abstract:
System and method for enabling a plurality of media feeds F 1 , F 2 , such as internet radio stations, to be played through a standard media player 14, such as a radio receiving device, using the tuning or input selection controls p(t) of the media player 14 to control the selection of which media feed F 2 to play. Identification signatures S m (t) are added to channels C(t) and transmitted x(t) to the media player 14 by transmitter 50. A controller 90 captures the playback output 10 of the media player 14 and, if it detects one of the signature signals S m (t), instructs the media feed selector 2 to select a media feed F 3 which corresponds to the detected identification signature. The selected audio feed F 3 is then transmitted to the media player 14 on the corresponding channel x(t) for playback.
Abstract:
Example methods and apparatus to generate identifying tags for media content as described herein. An example method includes obtaining an identifier value associated with at least one of audio or video of received media content by at least one of: extracting the identifier value from at least one of the audio or the video or determining the identifier value based on inherent information of at least one of the audio or the video, generating a tag including the identifier value, and storing the tag with the media content to cause the tag to be distributed to a presentation location along with the media content.
