Problem

Users face difficulties in quickly reviewing or obtaining an overall impression of a long list of media content items in a playlist, especially when sharing it with others.

Innovation Solution

A method and system for generating a media playlist preview, which involves identifying media content items, determining preview portions, arranging them with transition effects, and creating an audio object to summarize the playlist, allowing for easy sharing and collaborative user experiences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a playlist contains a long list of media content items, then the playlist can provide comprehensive content selection, but it becomes difficult to quickly review or obtain an overall impression of the media content items

Engineering Contradiction:
Improvenumber of media content itemsVSAvoidtime to review playlist
Core Design Contradiction:
Quantity of substanceVSLoss of time

Solution Approach 1:

The patent segments the long playlist into multiple smaller groups or sections, allowing users to review content in manageable chunks rather than as one overwhelming list. This segmentation enables faster scanning and better overall impression formation without sacrificing the comprehensive nature of the full playlist.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent extracts key representative information from each media content item (such as thumbnails, titles, or preview content) and presents them in a condensed format. This extraction allows users to quickly grasp the essence of the playlist contents without examining every single item in detail, significantly reducing review time.

Inventive Principle:
Principle #2Taking out (Extraction)

2Quantity of substance

If a playlist contains a long list of media content items, then the playlist can provide comprehensive content selection, but it becomes difficult to obtain an overall impression of the media content items

Engineering Contradiction:
Improvenumber of media content itemsVSAvoidoverall impression of media content
Core Design Contradiction:
Quantity of substanceVSLoss of information

Solution Approach 1:

The patent applies different presentation qualities to different parts of the playlist. Representative items or key content receive enhanced visual treatment (such as larger thumbnails or highlighted text) while less important items are presented in a more compact format. This local quality differentiation helps users quickly identify and form impressions of the most significant content without being overwhelmed by uniform detail across all items.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent performs preliminary organization and curation of the playlist content before presentation, pre-selecting representative items or arranging content in a way that naturally conveys the overall theme and quality. This preliminary action ensures that the overall impression is formed accurately and efficiently, without requiring users to mentally process every individual item.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If users share a playlist with other users, then collaborative experiences can be enabled, but it becomes difficult for other users to quickly understand the playlist content

Engineering Contradiction:
Improvesharing capabilityVSAvoidease of understanding playlist
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent creates a simplified copy or representation of the full playlist that can be easily shared and consumed. This copy includes essential information in a condensed format (such as a preview image, summary description, or truncated list) that convey the playlist's essence without requiring the full detailed view. This copying approach enables seamless sharing while maintaining ease of understanding for recipients.

Inventive Principle:
Principle #26Copying

AI summary

A playlist preview is generated to provide a preview of media content items identified by a media playlist. The playlist preview can be created by selecting all or some of the media content items in the playlist, determining preview portions of the selected media content items, and arranging the preview portions with or without a transition effect. The playlist preview can be easily shared with other users through, for example, social media sites.
