Unified Playback Controller for Seamless Multi-Provider Content Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of display devices, such as smart TVs or IPTVs, face inconvenience when trying to continuously reproduce multimedia content from multiple content providers as they need to manually execute and terminate multiple dedicated applications, making seamless playback between contents difficult.
Innovation Solution
A display device with a controller that manages and reproduces multimedia content from various providers by creating a playback list, sensing content reproduction completion, and switching between applications associated with different content providers, allowing for integrated content management and smooth transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple dedicated applications are used to reproduce content from different content providers, then content reproduction capability is improved, but operation complexity increases and seamless playback becomes difficult
Solution Approach 1:
The patent merges multiple dedicated applications into a single unified application that can reproduce content from multiple content providers. The playback list manager integrates content from different providers into one playlist, and the controller manages seamless transitions between contents without requiring users to switch between multiple applications, thus reducing operation complexity while maintaining content reproduction capability.
Solution Approach 2:
The unified application performs multiple functions by supporting content reproduction from various content providers through a single interface. The playback list manager can manage contents from different providers universally, and the controller handles diverse content types (audio, video, etc.) seamlessly, eliminating the need for provider-specific applications.
2Reliability
If manual execution and termination of multiple dedicated applications is required, then content provider specificity is maintained, but user convenience deteriorates and continuous reproduction is difficult
Solution Approach 1:
The playback list manager acts as an intermediary between the user and multiple content providers. It manages contents from different providers in a unified playlist without requiring users to interact with individual provider applications. The controller serves as another intermediary that handles the actual content reproduction and application switching in the background, maintaining provider specificity while improving user convenience.
Solution Approach 2:
The system performs automatic application execution and termination based on the playback list. When a content item is selected from the unified playlist, the controller automatically launches the appropriate application, reproduces the content, and terminates the application when finished, without requiring manual user intervention for each content transition.
3Ease of operation
If seamless playback between multiple contents is achieved, then user convenience is improved, but system complexity increases
Solution Approach 1:
The controller serves as an intermediary that manages the complexity of seamless playback. It automatically handles application launching, content reproduction, and termination based on the playback list, implementing seamless transitions without requiring complex user interactions. The playback list manager another intermediary that organizes content from multiple providers into a unified structure, simplifying the overall system architecture.

AI summary
A display device according to an embodiment of the present invention comprises: a display unit; a storage unit for storing a reproduction list including a first content provided by a first content provider and a second content provided by a second content provider; and a controller for displaying the reproduction list through the display unit, reproducing the first content included in the displayed reproduction list through an application associated with the first content provider, sensing whether the reproduction of the first content has been completed, and reproducing the second content through an application associated with the second content provider on the basis of a sensing result.
