Method for Sound Recognition Task Trigger

摘要

A system and method is described for monitoring a program signal for certain content, and performing a set of tasks when target content is recognized. Target content may be identified by using acoustic or video fingerprinting hardware or software to identify characteristic components of the program signal, and performing a lookup in a database of known content. When a match is made to known content, a task maybe performed such as muting the audio, blocking the video, or fast-forwarding past the content. A secondary action unit may be employed to receive control signals and rebroadcast the same to a media device. When the broadcast of the target media is determined to have completed, a corollary set of tasks are performed. In embodiments, the system may be implemented as one or more standalone hardware components, or in software.

主权项

1. A system adapted to monitor a content from a program stream, the system comprising:
an audio input subsystem configured to receive audio program data of the program stream, wherein the audio input subsystem is contained in a dongle configured to plug into an output port of a media device; an audio processing module contained in the dongle and configured to divide said program stream into frames of data and generate an identifier representing the frame of data; a database lookup module contained in the dongle, in communication with a database of program content identifiers, and configured to determine whether an identifier matches an entry in said database; a chain generation module contained in the dongle and configured to evaluate series of matches with said database and determine whether an action should be taken relative to said program stream; and a signal generator contained in a standalone unit distinct from the dongle and the media device, wherein the signal generator is configured to send a command to the media device, wherein the command commands the media device to take an action relative to said program stream, wherein the dongle is configured to instruct the standalone unit to send the command based on the determining.
