The present invention proposes a method for transmitting a broadcasting signal. The method for transmitting a broadcasting signal according to the present invention proposes a system that can support a next generation broadcasting service in an environment supporting next generation hybrid broadcasting which uses a terrestrial broadcasting network and an Internet network. Also, the present invention proposes an effective signaling scheme that can cover both the terrestrial broadcasting network and the Internet network in the environment that supports the next hybrid broadcasting.

Methods and apparatus for transcoding metadata are disclosed. Example apparatus disclosed herein include means for accessing first metadata accompanying media to be presented by a media device, the first metadata in a first format not detectable by a meter collecting audience measurement data associated with the media device. The example apparatus also include means for transcoding the first metadata into second metadata having a second format different from the first format, the second metadata detectable by the meter and supported by an application programming interface (API) provided by the media device and accessible by the meter. The example apparatus further include means for communicating the second metadata in a second transmission for receipt by the meter via the API provided by the media device, the second transmission being separate from a first transmission communicating the media and the first metadata, but not communicating the second metadata, to the media device.

In a network-based system for recommending media content items based on user preferences, clients contact a server on a periodic basis, independent of the user. In addition to client-server interaction, clients also interact with one another in peer-to-peer fashion. Peers query one another and evaluate their similarity to each other in an interactive comparison of user preferences. When two clients are sufficiently similar, the interaction culminates in the originating client downloading content listings from the targeted peer to generate suggestions for their user. If the two clients are dissimilar, the query may be terminated, or the targeted peer may route the query to a second targeted peer. In addition to the lists of preferences, the originating client may download actual content items from the targeted peers.

A method for matching a query against a broadcast stream includes receiving one or more broadcast streams, from which it generates and stores an audio fingerprint of a selected portion of each received broadcast stream. A query is received from which the method generates an audio fingerprint. From that point, the method continues by identifying audio content from the query, using the query audio fingerprint and a database of indexed audio content. The method concludes by identifying the source of the query using the query audio fingerprint and the stored audio fingerprints. Embodiments of the method further include predictively caching audio fingerprint sequences and corresponding audio item identifiers from a server after storing audio fingerprints extracted from the broadcast stream; and using the predictively cached audio fingerprint sequences to identify an audio item within the audio signal based on at least some additional audio fingerprints of the audio signal.
