Solution Overview

Problem

Excessive network transmissions of packet-based data can lead to inefficient bandwidth utilization, processor overload, and resource consumption, particularly when handling multiple content item objects, complicating data routing and response times.

Innovation Solution

A data processing system dynamically modulates packetized audio signals based on communication context, using different audio modulations for different portions of the signal to indicate content type, reducing resource consumption by minimizing additional data transmissions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple content item objects initiate network transmissions, then information can be delivered to users, but bandwidth utilization becomes inefficient and processor overload occurs

Engineering Contradiction:
Improveinformation transmission efficiencyVSAvoidbandwidth usage
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The patent combines multiple content item objects into a single audio message transmission. Instead of sending separate network transmissions for each content item, the system merges them into one consolidated audio message that delivers all relevant information efficiently, reducing bandwidth consumption and avoiding processor overload while maintaining information delivery productivity

Inventive Principle:
Principle #5Merging (Combining)

2Productivity

If multiple content item objects initiate network transmissions, then information can be delivered to users, but processor overload occurs and response times degrade

Engineering Contradiction:
Improveresponse timeVSAvoiddata routing complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent merges multiple content item objects into a single audio message, simplifying data routing from multiple separate transmissions to one consolidated transmission. This reduces routing complexity and prevents processor overload while maintaining the ability to deliver information to users in a timely manner

Inventive Principle:
Principle #5Merging (Combining)

3Loss of information

If audio messages are transmitted without modulation, then transmission is simple, but context information about content type is not conveyed to users

Engineering Contradiction:
Improvecontext informationVSAvoidaudio modulation complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent applies audio modulation techniques that change the acoustic characteristics (analogous to color changes) of audio messages based on their content type. Different modulations indicate whether audio represents user speech, system responses, or third-party content, conveying context information to users without requiring complex additional data transmissions or increasing system complexity significantly

Inventive Principle:
Principle #32Color changes

AI summary

Modulating packetized audio signals in a voice activated data packet based computer network environment is provided. A system can receive audio signals detected by a microphone of a client device. The system can parse the audio signal to identify trigger keyword and request, and generate a first action data structure. The system can identify a content item object based on the trigger keyword, and generate an output signal comprising a first portion corresponding to the first action data structure and a second portion corresponding to the content item object. The system can apply a different modulation to the first or second portion of the output signal, and transmit the modulated output signal to the client device. The different modulations may comprise applying modulation differently by shifting amplitude, by shifting frequency, by applying an audio overlay or applying an audio watermark to the respective portions.
