Playback Screen Attribute Switching for Portable Media
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable media players lack a system to efficiently switch from a playback screen to a list screen corresponding to different attributes, such as artist or album, while playing content, requiring users to return to the uppermost menu screen to access related content.
Innovation Solution
A reproduction device and display control method that allows switching from a playback screen to a list screen corresponding to selected attribute data, such as artist or album, while continuing content playback, using a control unit to manage hierarchical attribute data and display lists, with input operations controlling the cursor and scrolling for attribute selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users navigate through hierarchical attribute lists to find related content, then content retrieval is possible, but navigation complexity increases and playback continuity is interrupted
Solution Approach 1:
The attribute data is segmented into multiple hierarchical levels (first-level attributes like artist/album, second-level attributes like track listings). During playback, the system displays both first and second level attribute data on the same screen, allowing users to directly access either level without navigating through intermediate screens, thus reducing navigation steps while maintaining hierarchical organization.
Solution Approach 2:
The system transitions from a linear hierarchical navigation (screen-by-screen progression) to a two-dimensional display where multiple attribute levels coexist on the same playback screen. This dimensional change allows users to access different attribute levels simultaneously without interrupting playback, effectively adding a spatial dimension to the navigation structure.
2Adaptability or versatility
If the playback screen displays only current content information, then screen simplicity is maintained, but access to related content attributes becomes difficult
Solution Approach 1:
The playback screen is designed to serve multiple functions simultaneously: displaying current playback information, showing hierarchical attribute data (both first and second levels), and providing direct access points to related content. This multi-functionality allows the same screen to act as both a playback indicator and a navigation interface without requiring separate screens for each function.
Solution Approach 2:
The system merges the playback information display with the attribute navigation interface into a single integrated screen. The first-level attribute data and second-level attribute data are combined on the same display, allowing users to access related content attributes directly from the playback screen without switching to separate navigation screens.

AI summary
A reproduction device including a reproduction unit configured to reproduce content data including at least one of audio, video, and text for which attribute data is assigned for each of a different plurality of attributes; a display unit; and a control unit configured to make the display unit display a playback screen containing at least one attribute data among the plurality of attribute data assigned to the content data when reproducing the content data and, when one attribute data among the attribute data composing the playback screen is selected, switch the display content of the content from the playback screen to the list relating to the selected attribute data.
