Handwriting Animation Transcoder for Legacy Mobile Terminal Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile terminals that do not support animation reproduction formats face limitations in receiving and playing back handwriting animation data, as they are not compatible with the encoding formats used by transmitting terminals.
Innovation Solution
A method and apparatus that transcode handwriting animation messages, including coordinate and time information, into formats supported by the receiving mobile terminal, using an animation transcoder and mobile terminal profile database to ensure compatibility and enable playback on legacy devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If handwriting animation data is transmitted in a format supported by advanced mobile terminals, then the animation quality and functionality are improved, but legacy mobile terminals that do not support the format cannot reproduce the animation
Solution Approach 1:
The patent applies parameter changes by converting the encoding format parameter of handwriting animation data from a modern format (e.g., Flash, SVG) to legacy-compatible formats (e.g., animated GIF, JPEG sequence). The transcoder modifies format parameters to match the receiving terminal's capabilities, enabling broad compatibility while maintaining animation reproduction functionality across different device generations.
Solution Approach 2:
The patent introduces an intermediary transcoder component that mediates between the sender's modern animation format and the receiver's legacy format requirements. This transcoder acts as a bridge, automatically detecting the receiving terminal's format support and converting the animation data accordingly, thus resolving the compatibility conflict without requiring changes to either the sender or the receiver.
2Adaptability or versatility
If the transmitting terminal uses a modern animation format with rich features, then the expression capability is improved, but the device complexity increases due to the need for format detection and transcoding
Solution Approach 1:
The patent implements self-service by enabling the receiving terminal to automatically provide its format capability information to the transcoder. The terminal's profile database autonomously responds to format inquiry requests, allowing the transcoder to self-determine the appropriate conversion target format without manual intervention or complex negotiation protocols, thereby reducing system complexity.
Solution Approach 2:
The patent applies preliminary action by pre-storing format capability information in the receiving terminal's profile database before the actual animation transmission occurs. This advance preparation allows the transcoder to quickly query and determine compatible formats without real-time complexity, as the terminal's format support characteristics are already known and stored in advance.
3Productivity
If handwriting animation data is transmitted without format conversion, then the transmission speed is improved, but legacy terminals cannot reproduce the animation
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the format parameter of animation data based on the receiving terminal's capabilities. The transcoder modifies the encoding format parameter from modern formats to legacy-compatible formats only when necessary, maintaining high transmission efficiency for compatible terminals while ensuring broad compatibility through format adaptation when needed.
