Shared Playlist Management for Dynamic Content Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies fail to support joint activity among multiple users by allowing arbitrary selection and timely change of content playback in group settings, such as parties, as they do not enable real-time sharing and management of playlists across devices.
Innovation Solution
A communication system and method that includes a communication terminal with an acquisition unit to acquire meta-information from other terminals, a playlist management unit to manage shared playlists, and a display unit to show playlist screens, enabling users to select and change content playback dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If content playback is centralized controlled by a single terminal, then content selection and playback management is simplified, but other participants cannot select or change content on the spot
Solution Approach 1:
The patent merges the playlist management functions of multiple communication terminals into a shared playlist that is synchronized across all participating devices. Each terminal can contribute content to the shared playlist and access the collective selection, combining individual autonomy with group coordination. The shared playlist acts as a common resource that all participants can access and modify in real-time.
Solution Approach 2:
The shared playlist serves as an intermediary mechanism between individual terminal users and the content playback system. Instead of direct control or complete decentralization, the shared playlist mediates content selection by collecting contributions from multiple terminals, managing the content queue, and coordinating playback across the group, thus resolving the conflict between centralized control and individual autonomy.
2Adaptability or versatility
If playlist is shared across multiple terminals in real-time, then joint activity and content selection flexibility is improved, but system complexity and synchronization requirements increase
Solution Approach 1:
The shared playlist is designed as a universal data structure that can be accessed and modified by multiple communication terminals simultaneously. It serves multiple functions: storing content metadata from various sources, managing playback queues, coordinating synchronization, and enabling real-time updates. This multi-functional design reduces the need for separate mechanisms for each function, thereby managing complexity while supporting joint activity.
3Adaptability or versatility
If arbitrary participants can add content to playlist, then content variety and user engagement increase, but copyright protection becomes more difficult
Solution Approach 1:
The system implements feedback mechanisms where content contributions to the shared playlist are validated against copyright information databases. When a user attempts to add content, the system checks the content metadata, verifies licensing status, and provides feedback to the user about whether the content can be legally shared and played back. This automated feedback loop maintains copyright protection while allowing legitimate content variety.

AI summary
There is provided a communication terminal including an acquisition unit that acquires, from another communication terminal, meta-information associated with content stored in the other communication terminal, and a playlist management unit that manages a playlist which is shared with the other communication terminal and which is for playing back content corresponding to the meta-information acquired from the other communication terminal.
