Multimedia Player Seamless Mode Switching Without Playback Interruption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
MP3 players require users to stop and restart multimedia content when switching between video and audio playback modes, causing inconvenience as they need to convert replay modes manually.
Innovation Solution
A digital multimedia replaying apparatus and control method that allows seamless switching between basic and communication modes, enabling the transmission of video or audio content to an external apparatus while maintaining continuous playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the MP3 player converts to communication mode to transmit audio to a wireless headset, then the audio can be played through the external device, but the video and audio playback must be stopped and restarted
Solution Approach 1:
The patent enables continuous multimedia playback by allowing the player to maintain playback operations while simultaneously transmitting content to external devices. The system can continue playing video and audio locally while also sending audio streams to wireless headsets, eliminating the need to stop and restart playback when switching modes.
Solution Approach 2:
The MP3 player is designed to perform multiple functions simultaneously - it can act as both a local playback device and a content transmission source. The player integrates communication module capabilities with multimedia playback functions, allowing it to serve multiple purposes without requiring mode conversions that interrupt playback.
2Reliability
If the user manually operates the MP3 player to replay audio/video files after switching modes, then the correct content can be replayed, but the operation becomes inconvenient
Solution Approach 1:
The system automatically manages content replay based on the selected communication mode. When a user selects a wireless headset for audio transmission, the player automatically identifies and replays appropriate audio content without requiring manual intervention. The system self-manages the playback state and content selection, eliminating the need for users to manually operate the player to replay files.
3Loss of information
If the MP3 player displays all multimedia content information on the display panel, then the user can see detailed information, but the display becomes cluttered and less user-friendly
Solution Approach 1:
The patent extracts and separates different types of information display based on the operational mode. When in communication mode with a wireless headset, the display prioritizes showing relevant communication status and audio playback information rather than all possible multimedia content details. This extraction of essential information makes the display more focused and easier to use during different operational states.
Data Source
AI summary
A method for connecting an external apparatus and a multimedia replaying apparatus using the same. The method includes determining whether a command for displaying menus is input while multimedia content is replayed, determining a multimedia content replay state indicating whether a part or the whole of the multimedia contents is being replayed at an external apparatus if it is determined that the command for displaying menus is input, and displaying the menus comprising the multimedia content replay state on an area displaying a video of the multimedia contents. Therefore, a part or entire of replayed multimedia contents is readily transmitted to an external apparatus for wireless communication.
