AV Data Storage Medium With Representative Title Metadata
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing systems for storing and searching audio/video (AV) data on media, such as discs, become inefficient as the amount of meta data increases, leading to prolonged search times for users to find desired content.
Innovation Solution
Incorporating representative title information into the meta data structure, allowing for preferential searching of meta data, which speeds up the search process and provides users with abundant information by displaying disc and title information alongside search results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If meta data from multiple discs is stored in the player, then the user can search through a collection, but the search time increases significantly
Solution Approach 1:
The patent segments the meta data search process by introducing representative title information as a separate, prioritized search target. Instead of searching all meta data uniformly, the system divides search into two stages: first searching representative title information, then searching general title information only if needed. This segmentation reduces the effective search space in the first stage and accelerates retrieval.
Solution Approach 2:
The patent applies local quality by assigning different weights and priorities to different types of meta data. Representative title information is given higher priority and is searched preferentially, while general title information is searched secondarily. This differential treatment based on local characteristics optimizes search efficiency by focusing on the most relevant data first.
2Speed
If representative title information is added to meta data, then search speed improves, but the meta data structure becomes more complex
Solution Approach 1:
The patent implements nesting by placing representative title information within the existing meta data structure framework. The representative title information is integrated as a subset or layer within the broader meta data structure, allowing the system to leverage existing structure while adding new functionality. This nested arrangement minimizes structural disruption while achieving improved search performance.
Solution Approach 2:
The patent achieves multi-functionality by designing the representative title information to serve multiple purposes: it acts as a search priority marker, provides representative content identification, and maintains compatibility with existing meta data structures. This universal design allows the same structural element to fulfill multiple functions without requiring separate systems.

AI summary
An information storage medium having recorded thereon audio/video (AV) data including meta data with representative title information, and a method and apparatus for reproducing the AV data from the information storage medium, wherein the information storage medium having recorded thereon AV data including meta data includes storage medium information about the AV data recorded on the information storage medium and title information about at least one title constituting the AV data. The title information includes representative title information that designates at least one of the titles as a representative title.
