Abstract:
Methods, apparatus, and articles of manufacture for performing data insertion in compressed audio/video data streams are disclosed. A disclosed method receives a digital data stream containing a plurality of compressed media streams associated with a plurality of different media programs and generates information to be inserted in at least one of the compressed media streams. The disclosed method identifies frames of compressed data associated with the at least one of the compressed media streams and inserts the information in at least some of the identified frames of compressed data without performing a decompression operation on the compressed data and by changing locations or values of data bits within the at least some of the identified frames.
Abstract:
As disclosed herein, media metering functionality may be imparted to a panelists device that was not previously capable of media metering. According to one example, a method of providing a communication device with media metering functionality includes asking a potential panelist to participate in a survey, receiving an affirmative response from the potential panelist, and providing metering functionality to a portable device of the potential panelist.
Abstract:
Methods and apparatus for embedding and recovering an image for use with video content are disclosed. A disclosed system embeds a real component of a spectral representation of an image into a set of video frames and embeds an imaginary component of the spectral representation of the image into a second set of video frames. The two sets of video frames are combined and broadcast. The disclosed system recovers the real component of the spectral representation of an embedded image from a first set of received video frames and the imaginary component of the spectral representation of an embedded image from a second set of the received video frames.
Abstract:
Methods and apparatus to present survey information (107) are disclosed. In particular, the methods and apparatus present survey information (107) based on media compositions (306) and associated metadata information (304). The methods and apparatus are used to identify metadata (304) associated with a media composition (306) and generate a trigger compilation (405) based on survey information (107) and the metadata (304). An inband survey (308) is generated by multiplexing (406) the trigger compilation (405) and the media composition (306).
Abstract:
Methods and apparatus to count people appearing in an image are disclosed. One disclosed method reduces objects appearing in a series of images to one or more blobs; for each individual image in a set of the images of the series of images, represents the one or more blobs in the individual image by one or more symbols in a histogram; and analyzes the symbols appearing in the histogram to count the people in the image.
Abstract:
Methods, apparatus, systems and articles of manufacture are disclosed to measure an audience of an online media service. An example method includes requesting an access history associated with a subscriber of an online media service using a programming interface for the online media service; and determining ratings information using the access history and demographic information corresponding to the subscriber.
