Solution Overview

Problem

Conventional music reproduction systems require users to perform multiple operations to specify and reproduce multiple pieces of musical data in a streaming process, leading to inefficiency in content reproduction.

Innovation Solution

A content reproduction system that includes a content-providing apparatus and a content reproduction apparatus, where the content-providing apparatus selects and creates a reproduction list of contents reproducible by the content reproduction apparatus, allowing sequential provision and reproduction of contents according to the list.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If users manually specify each piece of musical data in a music reproduction terminal, then the system can reproduce multiple pieces of musical data in a streaming reproduction process, but the user must perform multiple music-specifying operations one after another, leading to low efficiency and high user labor

Engineering Contradiction:

Improvecontent reproduction efficiencyVSAvoiduser operation complexity

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The content providing apparatus creates a reproduction list in advance that specifies the reproduction order of multiple contents. This preliminary organization of content sequence eliminates the need for users to repeatedly specify each content individually, thereby improving reproduction efficiency while reducing operational complexity

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

A reproduction list is introduced as an intermediary data structure between the content providing apparatus and the music reproduction terminal. This reproduction list contains reproduction order information that mediates the transmission of content sequences, allowing the terminal to automatically reproduce multiple contents in the specified order without requiring multiple user operations

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the system provides multiple pieces of musical data for streaming reproduction, then the user can access more content, but the user must carry out multiple music-specifying operations to specify each piece of data

Engineering Contradiction:

Improvecontent selection capabilityVSAvoidtime for specifying operations

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The reproduction list is created in advance with the reproduction order of multiple contents already determined. This preliminary organization allows the system to provide versatile content selection capability while eliminating the time users would otherwise spend on multiple specifying operations, as the terminal automatically retrieves and reproduces contents in the pre-defined sequence

Inventive Principle:

Principle #10Preliminary action

3Productivity

If the music reproduction terminal requests and reproduces musical data individually, then the system maintains simple architecture, but the user cannot reproduce multiple pieces of musical data efficiently

Engineering Contradiction:

Improvecontent reproduction speedVSAvoidsystem architecture complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system architecture is segmented into distinct functional components: the content providing apparatus that creates and manages the reproduction list, and the music reproduction terminal that executes reproduction based on the list. This segmentation allows efficient multi-content reproduction while maintaining clear system boundaries and manageable complexity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The reproduction list serves as an intermediary data structure that enables efficient content reproduction without significantly increasing system complexity. It acts as a bridge between the content providing apparatus and the reproduction terminal, allowing the terminal to automatically process multiple contents in sequence based on pre-defined reproduction order information

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A content reproduction apparatus includes a communication unit that communicates with a content-providing apparatus. The content reproduction apparatus also includes a reproducing unit that reproduces content data. Further, the content reproduction apparatus includes a controller that transmits a request to the content-providing apparatus. The request indicates whether a data streaming reproduction service is available. The controller receives and reproduces a first one of an order of content data which is ordered by the content-providing apparatus based on the request. The controller also receives, after a determination that a second one of the order of content data exists, an attribute of the second one of the order of content data.
