Solution Overview

Problem

Existing content reproduction systems in home networks struggle to provide seamless and high-quality listening or viewing experiences as users move between rooms, as they lack efficient mechanisms for transferring content reproduction seamlessly across multiple devices.

Innovation Solution

An information processing method that calculates the distance to reproduction apparatuses using beacon signals and controls the transfer reproduction operation, including power supply and sound volume adjustments, to ensure continuous and high-quality content playback as the user moves, by synchronizing content transfer between devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If content reproduction is performed by multiple reproduction apparatuses in a home network, then the user can continuously reproduce content while moving between rooms, but the system lacks efficient mechanisms for seamless transfer reproduction between devices

Engineering Contradiction:
Improveseamless content transferVSAvoidtransfer mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system performs preliminary actions by continuously monitoring user position through beacon signals and pre-calculating distances to multiple reproduction apparatuses. When the user approaches a new apparatus, the system prepares the transfer reproduction in advance, ensuring seamless content transfer without user intervention.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms by continuously detecting user position relative to reproduction apparatuses using beacon signals. This real-time feedback enables the system to automatically determine when to initiate transfer reproduction, creating a responsive and seamless user experience.

Inventive Principle:
Principle #23Feedback

2Reliability

If the system automatically transfers content reproduction between apparatuses based on user position, then high-quality listening or viewing experience is achieved, but distance calculation and control mechanisms are required

Engineering Contradiction:
Improvecontinuous playback qualityVSAvoiddistance calculation system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system uses beacon signals as intermediaries to facilitate distance calculation between the user and reproduction apparatuses. These signals serve as a mediator that enables accurate position detection without requiring complex direct measurement systems, thus maintaining reliability while managing complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces complex mechanical distance measurement systems with electromagnetic beacon signals for position detection. This substitution achieves accurate distance calculation for transfer reproduction control while significantly reducing system complexity and improving reliability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If transfer reproduction is initiated based on distance threshold, then seamless user experience is achieved, but precise distance measurement and threshold control are needed

Engineering Contradiction:
Improveautomatic transfer initiationVSAvoiddistance measurement accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The system performs preliminary distance calculations using beacon signals to determine when the user approaches the threshold distance for transfer reproduction. This preliminary measurement ensures accurate and timely initiation of transfer reproduction, enhancing ease of operation while maintaining measurement precision.

Inventive Principle:
Principle #10Preliminary action

AI summary

To provide an information processing method, information processing apparatus, and information processing system which are capable of achieving a high-quality content listening or viewing experience. An information processing method according to an embodiment of the present technology is executed by a computer, and includes calculating, on a basis of a beacon signal which is transmitted from a reproduction apparatus capable of reproducing a content, a distance from the computer to the reproduction apparatus. On a basis of the calculated distance, a transfer reproduction operation by the reproduction apparatus is controlled, in which a content that is being reproduced by a different reproduction apparatus is transferred and reproduced.
