Solution Overview

Problem

Existing systems for transitioning media playback between electronic devices often result in significant changes to playback characteristics, such as volume levels, leading to an inconsistent user experience due to each device's internal settings.

Innovation Solution

A system and method that determine and adjust playback characteristics, like volume, by comparing values between the first and second electronic subsystems, ensuring a consistent user experience by transmitting control instructions to synchronize playback settings across devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If each electronic device plays back media using its own internal playback settings, then the device can operate independently with its own configuration, but the playback characteristics dramatically change when transitioning between devices

Engineering Contradiction:
Improvedevice independenceVSAvoidplayback characteristic consistency
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The system transmits control instructions from a first electronic device to a second electronic device based on determined relationship values and playback values. The second device receives and applies these instructions to adjust its playback characteristics, creating a feedback loop that ensures consistent user experience across devices while maintaining independent operation capabilities

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system dynamically adjusts playback parameters (such as volume levels) by transmitting control instructions that modify the second device's playback characteristics based on the first device's settings and the determined relationship value, enabling consistent playback across different devices

Inventive Principle:
Principle #35Parameter changes

2Stability of the object's composition

If the system transmits control instructions to synchronize playback settings, then playback characteristic consistency is improved, but the system complexity increases

Engineering Contradiction:
Improveplayback characteristic consistencyVSAvoidsystem complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The control instruction transmission mechanism serves multiple functions: it communicates playback settings, conveys relationship values between devices, and synchronizes characteristics across devices. This multi-functional approach reduces the need for separate dedicated components for each function, thereby managing system complexity while achieving playback consistency

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

Systems, methods, and computer-readable media for transitioning media playback between multiple electronic devices are provided. A first electronic subsystem may be configured to playback first media with a first playback value of a first playback characteristic, determine a first relationship value of a first relationship characteristic between the first electronic subsystem and the second electronic subsystem, and transmit a first control instruction that is based on the determined first relationship value and the first playback value. The second electronic subsystem may be configured to receive the transmitted first control instruction and playback second media with a second playback value of the first playback characteristic, where the second playback value may be based on the received first control instruction. This may enable a consistent experience for a user proximate to the first subsystem as the playback of media is transitioned from the first subsystem to the second subsystem.
