The present disclosure provides identification and continuous monitoring of content, such as broadcast content, in real time, using a hierarchical, distributed approach to content identification. Identification, synchronization and verification are provided. Identification may be performed by an identification server using a reference database of fingerprints. The same or another computing device may be used perform synchronization, such that at least some portion of each fingerprint generated by client devices that form a verification group are synchronized for verification. Verification used to determine whether a client device continues to receive the same content identified during identification compares at least a portion of each fingerprint generated by each client device of a verification group. If a mismatch occurs, identification may be repeated to identify the new content being received by a client device.

Continuous content identification of broadcast content

Methods and system for identifying multimedia content streaming through a television includes retrieving an audio signal from a multimedia content selected for rendering at the television. The retrieved audio signal is partitioned into a plurality of segments of small intervals. A particular segment is analyzed to identify acoustic modulation and to generate a distinct vector for the particular segment based on the acoustic modulation, wherein the vector defines a unique fingerprint of the particular segment of the audio signal. A content database on a server is queried using the vector of the particular segment to obtain content information for multimedia content that matches the fingerprint of the particular segment. The content information is used to identify the multimedia content and the source of the multimedia content that matches the audio signal received for rendering.
