Solution Overview

Problem

Existing playback devices require user intervention to search for video content related to music data, which is inconvenient.

Innovation Solution

A playback device that communicates with a terminal device to receive music data and information, generates a search expression for video data based on the music information, and transmits this expression over a network to a server, allowing for automatic retrieval and display of video information without user involvement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the playback device requires user intervention to search for video content, then the user can control the search process, but the operation becomes complex and time-consuming

Engineering Contradiction:
Improveease of searching for video contentVSAvoidtime required for user to search and connect to internet
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The playback device automatically performs video content search without requiring user intervention. The device uses its communicator to autonomously connect to the internet, send search requests based on music data information, and retrieve video content, thereby serving itself rather than requiring user operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The playback device performs preliminary actions by maintaining internet connection capability and pre-configuring search functionality. When music data is received, the device immediately has the capability to search for and retrieve video content without requiring the user to first establish internet connection or configure search parameters.

Inventive Principle:
Principle #10Preliminary action

2Extent of automation

If the playback device automatically searches for video content, then the operation is simplified, but the device complexity increases

Engineering Contradiction:
Improveautomation of video content searchVSAvoidcomplexity of communication and search functions
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The playback device incorporates a communicator that can perform multiple functions: receiving music data from external devices, connecting to the internet for video content search, and retrieving search results. This multi-functional component reduces overall device complexity by consolidating diverse functions into a single versatile module.

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

Solution Approach 2:

The patent combines the music data reception function and video content search function into a single integrated playback device. The communicator handles both music data transmission and internet communication, merging multiple functions into one unified system rather than requiring separate devices.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If the playback device uses a single communication scheme, then the device is simpler, but it cannot simultaneously receive music data and search for video content

Engineering Contradiction:
Improveability to use multiple communication schemesVSAvoidcomplexity of multiple communication interfaces
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The communicator is designed as a universal communication interface that can operate with multiple communication schemes. It can receive music data from external devices using one communication protocol while simultaneously or sequentially connecting to the internet using another protocol, providing adaptability without requiring separate dedicated hardware for each function.

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

AI summary

A playback device (2) includes a first communicator (10) that communicates with a terminal device (26) through a first communication scheme and that receives music data and music information indicating an attribute of the music data from the terminal device (26), a music information storage (12) that stores the music information received by the first communicator (10), a music player (14) that plays back the music data received by the first communicator (10), a search processor (16) that generates search data for searching for information related to the music data based on the music information, and a second communicator (18) that communicates via a network through a second communication scheme different from the first communication scheme and that transmits the search data and receives a search result for the search data. The search processor (16) outputs the search result received by the second communicator (18).
