Solution Overview

Problem

Existing media streaming technologies face challenges in delivering personalized audio content efficiently to diverse user populations due to bandwidth limitations, as they often require multiple self-contained versions of audio content, which can be inefficient and impractical for devices with limited network resources.

Innovation Solution

The development of a system that generates and delivers personalized audio metadata to adaptive streaming clients, allowing them to select and stream specific audio presentations from a set of audio program elements, optimizing bandwidth usage by transmitting only the necessary elements for each presentation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple self-contained versions of audio content are created for different user segments, then personalization capability is improved, but bandwidth consumption increases

Engineering Contradiction:

Improvepersonalization capabilityVSAvoidbandwidth consumption

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The audio content is segmented into a common audio bed and multiple language-specific audio tracks. Instead of delivering complete separate audio versions, only the necessary language tracks are transmitted to each client based on their preferences, while the common audio bed is shared across all users.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The common audio bed serves multiple functions simultaneously - it provides the base audio content for all users regardless of language preference, eliminating the need for separate audio beds in each language version and reducing overall bandwidth consumption.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple self-contained versions of audio content are delivered concurrently, then personalization capability is improved, but network resource efficiency deteriorates

Engineering Contradiction:

Improvepersonalization capabilityVSAvoidnetwork resource efficiency

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The language-specific audio tracks are extracted as separate, independent components from the complete audio versions. Clients only receive and process the extracted language tracks they need, rather than downloading entire audio versions containing all language content.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The audio delivery system dynamically adapts to each client's language preferences and network conditions, adjusting which audio tracks are transmitted in real-time rather than delivering fixed, static audio versions to all users.

Inventive Principle:

Principle #15Dynamics

3Reliability

If complete audio versions are transmitted to all clients, then audio quality is maintained, but bandwidth consumption increases

Engineering Contradiction:

Improveaudio qualityVSAvoidbandwidth consumption

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

Each client receives audio content tailored to its specific language requirements. The audio quality is maintained for the relevant language tracks while avoiding transmission of unnecessary language content to specific regions or users.

Inventive Principle:

Principle #3Local quality

AI summary

Personalized audio metadata is generated based on audio program elements and presentation configuration metadata to specify personalized audio presentations for a media presentation. The personalized audio metadata is transmitted to an adaptive streaming client in response to receiving a media presentation request by the adaptive streaming client for the media presentation. Audio program elements of a specific personalized audio presentation are transmitted to the adaptive streaming client in response to receiving subsequent media streaming requests for the audio program elements.
