摘要:
Methods and apparatus for preparing media content for identification are disclosed. An example method includes receiving compressed media content, decompressing the payload of the compressed media content, generating a signature of the decompressed payload, discarding the decompressed payload, embedding a code in the compressed media content, and storing the code and the signature in a database for later use in identifying presentation of the media content at a presentation site.
摘要:
Methods and apparatus to present survey information are disclosed. In particular, the methods and apparatus present survey information based on media compositions and associated metadata information. The methods and apparatus are used to identify metadata associated with a media composition and generate a trigger compilation based on survey information and the metadata. A inband survey is generated by multiplexing the trigger compilation and the media composition.

Methods and apparatus to measure exposure to streaming media are disclosed herein. An example method includes extracting metering data from media obtained from a media provider. Metadata identifying the media based on the extracted metering data is generated. The media is transcoded into a transport stream, the transport stream having a streaming format. The metadata is embedded in a timed text track accompanying the transport stream.

Methods and apparatus for monitoring video games are disclosed. An example method disclosed herein comprises monitoring game content corresponding to a game medium played by a game console, processing the game content to determine a set of metering data, and cross-referencing the set of metering data with a set of reference data corresponding to a set of known games.
摘要:
Methods and apparatus for detecting space-shifted media content associated with a digital recording/playback device are disclosed. An example method for detecting space-shifted media content includes receiving media content at a first recording/playback device at a first viewing site at a monitored location, requesting data associated with the media content from a second device at the monitored location, and determining if the data associated with the media content indicates that the media content has been space-shifted to the first recording/playback device.
摘要:
Methods and apparatus to determine audience viewing of video-on-demand programs are disclosed. An example method disclosed herein comprises creating a reference database corresponding to a set of VOD programs, determining whether a VOD program is selected at a subscriber site, extracting at least one identifier from a signal carrying the VOD program, and cross-referencing the at least one identifier with the reference database.
摘要:
Methods and apparatus to determine audience viewing of recorded programs are disclosed. An example method disclosed herein comprises displaying a previously recorded program on a display, determining a possible original broadcast time corresponding to the previously recorded program, determining program identifying information corresponding to the previously recorded program, and processing the possible original broadcast time information and the program identifying information to compare the previously recorded program with a known broadcast program.
摘要:
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.
摘要:
Encoding and decoding methods and apparatus are described to obtain auxiliary information from an audio signal. The auxiliary information uses a plurality of frequency components residing in a plurality of code bands. The audio signal is transformed into a frequency domain representation. Characteristics of frequencies of the frequency domain representation that may contain the auxiliary information are determined. The characteristics of frequencies of the frequency domain representation in a respective one of the code bands that may contain the auxiliary information are normalized across the code band. The normalization is carried out against a characteristic of a frequency in that code band. The normalized characteristics of the frequencies representative of auxiliary information are summed to determine a sum for a frequency representative of auxiliary information. It is determined when the sum is representative of the auxiliary information.
