Moving Picture Server Difference Data Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Many mobile telephones can only reproduce moving pictures if the data is complete moving picture data, but not if it is difference moving picture data, which limits the playback of moving pictures transmitted as difference data.
Innovation Solution
A moving picture server system that converts difference moving picture data to complete moving picture data and stores it at a specified location, allowing for immediate transmission to mobile terminals capable only of reproducing complete moving picture data upon request.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If difference moving picture data is transmitted to mobile terminals, then data transmission efficiency is improved, but playback compatibility deteriorates because many mobile terminals cannot reproduce difference data
Solution Approach 1:
The patent introduces a server as an intermediary between the data transmission source and mobile terminals. The server receives difference moving picture data, converts it to complete moving picture data, and then transmits it to mobile terminals. This intermediary component enables compatibility with terminals that cannot directly process difference data while maintaining the efficiency benefits of difference data compression.
Solution Approach 2:
The patent changes the data format parameter from difference moving picture data to complete moving picture data through conversion processing on the server. This parameter transformation allows the data to be compatible with mobile terminals that only support complete data formats, while the original difference data format is preserved for efficient transmission and processing.
2Adaptability or versatility
If complete moving picture data is generated from difference data, then playback compatibility is improved, but processing time and storage requirements increase
Solution Approach 1:
The patent implements preliminary conversion of difference moving picture data to complete moving picture data on the server before transmission to mobile terminals. This preliminary action ensures that the data is ready in the correct format for immediate playback on compatible terminals, reducing the processing time that would otherwise be required at the terminal end or during playback initiation.
3Quantity of substance
If difference moving picture data is used, then storage capacity requirements are reduced, but device complexity increases due to the need for conversion processing
Solution Approach 1:
The server acts as an intermediary that handles the complex conversion processing from difference to complete moving picture data. This separates the complexity of data conversion from the mobile terminals, allowing terminals to use simpler storage and processing capabilities while the server manages the computational requirements of format conversion.
Solution Approach 2:
The patent changes the data representation parameter from difference-based compression to complete frame representation. This parameter change reduces the storage capacity requirements at the terminal level while the conversion processing complexity is centralized on the server, which has greater computational resources.
Data Source
AI summary
E-mail to which difference moving picture data is attached is transmitted from a mobile telephone for displaying difference moving pictures to a mail server. The mail server separates the difference moving picture data from the e-mail and transmits it to a moving picture converting server. The moving picture converting server converts the difference moving picture data to complete moving picture data and stores the complete moving picture data in a database. A URL link indicating the storage location in the database is generated by the mail server and transmitted to a mobile telephone for displaying complete moving pictures.
