DLNA Device Managing Multiple Media Playback States
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Digital Living Network Alliance (DLNA) technologies are limited in sharing multiple media content across home networks, as they primarily provide media sharing through a single medium using an on-screen interface, lacking the capability for individual control of multiple devices.
Innovation Solution
A DLNA device and method that includes a display unit, input unit, communicator, and controller, enabling the selection and execution of multiple DLNA service scenarios by storing scenario selection information, URI information, and playback state information, allowing for simultaneous management and control of media content across multiple devices in a home network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single medium on-screen interface is used for DLNA media sharing, then the interface design is simple, but the capability to share multiple media content and control multiple devices is limited
Solution Approach 1:
The patent segments the media sharing functionality into multiple independent DLNA service scenarios (2-Box Push, 2-Box Pull, 3-Box scenarios), each handled by separate processing modules. This allows the system to manage multiple media content and devices through structured, discrete functional units rather than a monolithic complex interface.
Solution Approach 2:
The patent implements a universal DLNA device that can perform multiple functions by supporting various DLNA service scenarios simultaneously. The device can act as DMS, DMP, DMR, or DMC depending on the selected scenario, enabling a single device to handle diverse media sharing needs without requiring separate specialized interfaces for each function.
2Adaptability or versatility
If multiple DLNA service scenarios are supported simultaneously, then the media sharing capability is enhanced, but the control and management complexity increases
Solution Approach 1:
The patent employs preliminary action by pre-configuring multiple DLNA service scenarios with their respective parameter sets before execution. The system stores scenario selection information, URI information, and playback state information in advance, allowing users to select from pre-prepared configurations rather than managing complex real-time settings, thus simplifying control while maintaining enhanced media sharing capability.
Solution Approach 2:
The patent implements feedback mechanisms that monitor playback state information for each DLNA service scenario and provide status updates to the user interface. This allows the system to manage multiple scenarios transparently, automatically adjusting control based on current playback states while presenting a simplified overview to the user, reducing the perceived complexity of controlling multiple media streams.

AI summary
A DLNA device for sharing multiple home media content comprises a display unit, an input unit, a communicator, a controller and a data storage unit. The display unit is configured to display a user interface for implementing at least one individual DLNA service scenario. The input unit is configured to receive a DLNA service scenario selection information including server selection information, content selection information and player selection information through the user interface. The communicator configured to communicate with a DLNA network. The controller is configured to perform the at least one individual DLNA service scenario based on the DLNA service scenario selection information received through the input unit. The data storage unit configured to store scenario selection information, uniform resource identifier (URI) information of a content and playback state information corresponding to each individual DLNA service scenario.
