Portable Device Motion Picture Customization and Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable devices lack the capability to edit motion pictures according to user intentions and efficiently transmit customized content, limiting user-generated content creation and sharing.
Innovation Solution
A method in a portable device that detects events during motion picture playback, extracts and synchronizes video and audio streams, allows users to create customized audio streams, and compiles them into user motion picture files, which can be attached to messages and transmitted via MMS.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional portable device is used, then the device can play stored motion pictures, but the device cannot edit or customize motion pictures according to user intentions
Solution Approach 1:
The portable device is enhanced to perform multiple functions including playing stored motion pictures, detecting events during playback, extracting video and audio streams, creating customized audio streams, and compiling user motion picture files. This multi-functionality allows the device to edit and customize motion pictures without requiring separate dedicated equipment.
Solution Approach 2:
The device uses its own internal resources (processor, memory, storage) to perform event detection, stream extraction, audio stream creation, and video compilation during playback. The system serves itself by utilizing existing playback infrastructure rather than requiring external editing equipment, thereby avoiding increased device complexity.
2Productivity
If users want to create and share unique media contents, then user-generated content creation is needed, but conventional devices lack efficient transmission capabilities for customized content
Solution Approach 1:
The device creates user motion picture files with customized audio streams and compiles them into ready-to-transmit formats during the playback process. By preparing the content in advance with proper formatting and compilation, the device eliminates complex post-processing steps required for sharing, thereby improving both creation efficiency and ease of transmission.
Solution Approach 2:
The system combines the motion picture playback function with the content creation and transmission functions into a single integrated process. Event detection, stream extraction, audio stream creation, video compilation, and message transmission are merged into one workflow, allowing users to create and share customized content efficiently without separate operations.
3Adaptability or versatility
If event detection and simultaneous stream extraction are implemented, then user motion picture creation is enabled, but processing complexity increases
Solution Approach 1:
The processor acts as an intermediary that coordinates between the playback system, event detection mechanism, stream extraction processes, and compilation functions. By centralizing control in the existing processor, the system manages the complexity of simultaneous operations without requiring additional dedicated hardware components for each function.

AI summary
Disclosed is a method of creating motion pictures in a portable device. The method includes detecting whether an event occurs while a stored motion picture file is being played, if an event occurs, extracting and playing a video stream of the motion picture file simultaneously after the occurrence, and creating a user motion picture file by producing a user audio stream and compounding the user audio stream with the extracted video stream. Further disclosed is a method of providing contents in a portable device. This method includes selecting a stored receiver's information, saving and playing simultaneously, if an event occurs, a video stream of the motion picture file after the occurrence, creating a customized audio stream according to the receiver's information and producing a user's motion picture file by compounding the audio stream with the video stream, attaching the user's motion picture file to a message, and transmitting the message.
