DLNA User Interface Three-Frame Layout for Content Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Digital Living Network Alliance (DLNA) system user interfaces are cumbersome, requiring users to perform multiple steps to select and output desired multimedia content, as they are not easily displayed on one screen, leading to user inconvenience due to the complexity of device and content type management.
Innovation Solution
A user interface configured using three frames is introduced, where all source, renderer, and menu items are set on axes, allowing users to select two axes and a contents list based on their operation, thereby simplifying the display and selection process by integrating information about source and renderer devices within the interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional DLNA user interface is used, then device and content management functionality is provided, but the interface becomes cumbersome and complex requiring multiple steps for selection and output
Solution Approach 1:
The user interface is divided into three distinct frames: a first frame for selecting source devices, a second frame for selecting renderer devices, and a third frame for displaying and selecting content. This segmentation allows users to interact with each frame independently, reducing the complexity of managing all devices and content in a single interface while maintaining complete functionality.
Solution Approach 2:
The interface transitions from a single-screen two-dimensional layout to a multi-frame three-dimensional navigation structure. By adding the dimension of frame sequencing (first frame, second frame, third frame), the system provides a more intuitive navigation path that reduces the number of steps required to complete content selection and output operations.
2Adaptability or versatility
If multiple steps are required for content selection and output, then comprehensive device and content management is achieved, but user convenience is reduced due to the number of operations needed
Solution Approach 1:
The interface pre-organizes device and content information across three frames before the user needs to make selections. Source devices are pre-listed in the first frame, renderer devices in the second frame, and available content in the third frame. This preliminary organization eliminates the need for users to navigate through multiple menus and reduces the time required to complete content selection and output operations.
3Loss of information
If all source, renderer, and menu items are integrated on one screen, then complete information is displayed, but the interface becomes difficult to navigate and use
Solution Approach 1:
The interface segments the display of source devices, renderer devices, and content into three separate frames. Each frame focuses on a specific aspect of the DLNA system, making the information more digestible and easier to navigate. Users can access complete information by sequentially viewing the frames in order, maintaining information completeness while improving ease of operation.

AI summary
A method for providing a user interface configured using three frames for a Digital Media Player (DMP) in a Digital Living Network Alliance (DLNA) system. Each of all source, renderer, and menu items of the DLNA system is set to one axis of a set of axes. Two predetermined axes of the set of axes and a contents list are selected according to selection by a DMP user of an operation to be performed within the DLNA system. A user interface of the DMP is configured using two frames for displaying the two predetermined axes and one frame for displaying the contents list.
