Radio Broadcast Audio Fingerprinting Suitability Filter

Solution Overview

Problem

Current radio broadcast systems incur high costs and resource consumption due to the reliance on digital fingerprinting for identifying audio content, which can fail if the broadcast audio is not suitable for the process, such as during talk programs or commercials.

Innovation Solution

A system that determines the suitability of the audio content for fingerprinting before initiating the fingerprinting process, using an intermediate communication platform and a server to provide metadata indicating whether the content is suitable for audio fingerprinting, thereby preventing unnecessary resource usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If audio fingerprinting is used to identify radio broadcast content, then content identification capability is improved, but memory consumption and processing resource usage increase

Engineering Contradiction:

Improvecontent identification capabilityVSAvoidmemory consumption

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The server performs preliminary analysis of the radio broadcast audio content to determine suitability for fingerprinting before the radio receiver actually performs the fingerprinting process. This preliminary action filters out unsuitable content (such as talk programs and commercials) before resource-intensive fingerprinting is attempted, thereby reducing unnecessary memory and processing resource consumption at the receiver end.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If audio fingerprinting is performed on all radio broadcasts, then content identification coverage is improved, but processing resource consumption increases

Engineering Contradiction:

Improvecontent identification coverageVSAvoidprocessing resource consumption

Core Design Contradiction:

ReliabilityVSPower

Solution Approach 1:

The server performs preliminary analysis of the radio broadcast audio content to determine suitability for fingerprinting before the radio receiver actually performs the fingerprinting process. This preliminary action filters out unsuitable content (such as talk programs and commercials) before resource-intensive fingerprinting is attempted, thereby reducing unnecessary memory and processing resource consumption at the receiver end.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The server provides feedback information to the radio receiver in the form of metadata that indicates whether the broadcast content is suitable for fingerprinting. This feedback mechanism enables the receiver to make informed decisions about whether to perform fingerprinting, optimizing the balance between identification coverage and processing resource consumption by only attempting fingerprinting on suitable content.

Inventive Principle:

Principle #23Feedback

3Reliability

If audio fingerprinting is attempted on all broadcast content, then identification service coverage is improved, but cost increases

Engineering Contradiction:

AI summary

A system comprises an intermediate communication platform that provides an interface to an Internet network; and a first server including: a port operatively coupled to the intermediate communication platform, processing circuitry, and a service application for execution by the processor. The service application is configured to: receive geographic location information of a radio receiver via the intermediate communication platform; determine one or more radio broadcasts available to the radio receiver according to the geographic location information; and send metadata for the radio broadcast, the metadata including an indication whether content of the radio broadcast is suitable for an audio fingerprinting process to the radio receiver via the intermediate communication platform.
