Playback System Content Extraction for Special Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing playback systems lack the ability to perform special playback based on the details of content, making it difficult for users to efficiently find specific portions or highlights within large collections of content, such as videos or music, leading to reduced usability.
Innovation Solution
A playback system that includes a category determining unit, a playback instruction data generator, and an extracting unit, which determine and extract specific portions of content for special playback types like abstract and highlight playback, based on predefined rules associated with the content category, allowing for enhanced user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If high-speed playback is used to search for desired content, then the speed of content search is improved, but the user still needs to make significant efforts to find specific content from large collections
Solution Approach 1:
The patent extracts and plays back only the essential portions of content (such as speaker voice sections and ticker sections) to create a digest version. This allows users to quickly understand content without watching or listening to the entire material, significantly reducing the effort required to find desired information while maintaining search speed.
Solution Approach 2:
The system performs preliminary analysis of content to identify and mark important sections (speaker voice sections, ticker sections, highlight sections) before playback. This pre-processing creates playback instruction data that guides the playback device to automatically select and play back only the relevant portions, saving users time and effort in content navigation.
2Ease of operation
If special playback according to content details is implemented, then the usability of the player is improved, but the device complexity increases
Solution Approach 1:
The patent introduces playback instruction data as an intermediary element that bridges the gap between content and playback control. This data structure (containing section start/end times and playback speeds) acts as a mediator that enables intelligent playback without requiring complex real-time analysis, thus improving usability while keeping the system structure manageable.
Solution Approach 2:
The content is segmented into distinct sections (ticker sections, speaker voice sections, highlight sections) with specific characteristics. Each section is assigned appropriate playback parameters independently, allowing the system to handle different content types efficiently without requiring a completely complex unified processing approach.
Data Source
AI summary
A playback instruction data generator determines, for each type of exceptional and special playback, a portion of target content with specific details to be played back in exceptional and special playback of the target content, on the basis of a playback rule for the category of the target content, among playback rules defined for each category of content and for each type of exceptional and special playback, and generates playback instruction data in which portion-to-be-played information indicating that portion is associated with identification information identifying the target content. A data extracting unit extracts, from content specified by a user, a portion of the content with specific details indicated by the portion-to-be-played information for the type of exceptional and special playback specified by the user, the portion-to-be-played information being included in the playback instruction data and being associated with the identification information for the content specified by the user. The present invention is applicable to, for example, an apparatus that records and plays back content, such as images.
