Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a mobile terminal controls a video output device using conventional methods, then basic control functions are achieved, but the control optimization and video output efficiency are insufficient
Solution Approach 1:
The patent segments the user interface into distinct functional areas: a first area for displaying folders containing videos and a second area for displaying EPG information. This segmentation allows users to efficiently access and manage video content while receiving optimized control instructions for the video output device, thereby improving video output efficiency without requiring a completely complex control system.
Solution Approach 2:
The patent implements preliminary action by pre-generating virtual channels based on folders of videos stored in the mobile terminal before user selection. When a user interacts with a folder in the first area, the system has already prepared the corresponding virtual channel information, enabling rapid video output to the external device without requiring complex real-time processing during user interaction.
2Ease of operation
If virtual channels are generated for timed video output, then video output optimization is achieved, but the system complexity increases
Solution Approach 1:
The patent applies copying by creating virtual channels that replicate the functionality of physical broadcast channels. Instead of requiring complex new control mechanisms, the system copies the familiar channel concept from traditional TV and applies it to stored video content. Users can select and output videos through these virtual channels in a manner similar to selecting broadcast channels, greatly simplifying operation while the system handles the complexity of timed video playback and channel management in the background.
3Ease of operation
If folders and EPG are displayed in separate areas, then user interface optimization is achieved, but the display area requirements increase
Solution Approach 1:
The patent utilizes the touch screen's two-dimensional space by dividing it into distinct functional areas: a first area for folders and a second area for EPG. This dimensional organization allows users to simultaneously access video content selection and program information without requiring additional physical space beyond the existing touch screen, while significantly improving interface usability through intuitive spatial separation of functions.

AI summary
A mobile terminal and a method for controlling the same that may perform wireless communication with a video output device are disclosed. The mobile terminal comprises a wireless communication unit configured to perform wireless communication with a video output device; a touch screen; and a controller controlling the touch screen to output at least one folder to a first area of the touch screen and output an electronic program guide (EPG), which includes channel information related to the video output device, to a second area different from the first area, wherein the controller, if a predetermined touch is applied to any one of the at least one folder output to the first area, generates a virtual channel configured to output videos included in the any one folder from the video output device, and changes the EPG such that channel information corresponding to the generated virtual channel is reflected in the EPG.
