Metadata Generation for User-Recorded Content Sharing

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional communication systems cannot share content lacking generative information, such as user-recorded videos, as metadata cannot be generated for these files, preventing their download and sharing based on metadata.

Innovation Solution

A communication apparatus and method that generates metadata for content without existing generative information, allowing sharing by inputting user-generated metadata, and includes features like preference learning, database registration, and content list generation for sharing content across networks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional sharing systems rely on pre-existing generative information (EPG data) to generate metadata, then metadata can be automatically generated for broadcast content, but content without generative information (user-recorded videos) cannot be shared

Engineering Contradiction:

Improvecapability to share contentVSAvoidabsence of metadata

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent introduces an intermediary component (metadata generation unit) that bridges the gap between content without generative information and the sharing system. This intermediary automatically creates metadata by analyzing content characteristics (video frames, audio signals, file properties) and generating descriptive information, enabling content to be shared without pre-existing EPG data.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system enables self-service metadata generation where the content itself provides the information needed for metadata creation. The metadata generation unit extracts characteristics directly from the content (video, audio, file structure) to automatically generate descriptive metadata, eliminating the need for external generative information sources.

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If metadata is manually input for user-recorded content, then sharing becomes possible, but the process becomes complex and time-consuming

Engineering Contradiction:

Improvecapability to share user-recorded contentVSAvoidmetadata generation process

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent replaces the manual mechanical process of metadata input with an automated information processing system. The metadata generation unit uses computational methods to automatically extract content characteristics and generate metadata, substituting manual operations with automated technical processes that reduce complexity and time requirements.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system changes the parameters of metadata generation from manual input fields to automated extraction based on content analysis. By analyzing video frames, audio signals, and file properties, the system dynamically generates metadata parameters without requiring manual specification, simplifying the overall process.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If automated metadata generation from content analysis is implemented, then sharing of content without generative information becomes feasible, but processing time and computational resources increase

Engineering Contradiction:

Improveability to process content without EPG dataVSAvoidmetadata generation time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent applies partial action by generating only the essential metadata needed for sharing based on the most significant content characteristics. Rather than analyzing every aspect of the content in depth, the system focuses on key features (primary video frames, dominant audio characteristics, fundamental file properties) to generate sufficient metadata efficiently, balancing comprehensiveness with processing time.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

The present invention relates to a communication apparatus, a communication method, and a communication system able to share content on the basis of metadata. A storage unit 105 retains content. A registration processor 106 generates metadata related to the content and registers the generated metadata in a database. An uploader 104 requests another communication apparatus via a network for content retained by the other communication apparatus on the basis of metadata generated by the other communication apparatus. A downloader 103 supplies content retained by the storage unit 105 via the network to the other communication apparatus requesting on the basis of metadata generated by the registration processor 106. The present invention can be applied to a recording and playback apparatus able to record or play back content, for example.
