Abstract:
1. A method for identifying multimedia content streaming to a television, the method executed by a processor, comprising: retrieving an audio signal for multimedia content selected for rendering at the television; partitioning the audio signal into a plurality of segments; analyzing a particular segment to identify acoustic modulations in the particular segment, the analysis generating a vector for the particular segment based on the acoustic modulation, the vector defining an unique audio fingerprint of the particular segment of the audio signal, wherein the vector identifies a plurality of floating point numbers of data points representing the unique audio fingerprint; and querying a content database on a server using the vector of the particular segment of audio signal to identify information data for the multimedia content, the content database including a plurality of pre-computed data points and each pre-computed data point is associated with information data for different multimedia content including the multimedia content rendered, wherein the information data is identified by finding a substantial match of the vector to data points in the content database, the querying causing the identified information data to be retrieved and stored in a local cache for local verification that the selected multimedia content remains selected, the retrieved and stored information data being valid for an upcoming additional amount of time.
