Virtual Multimedia File System for Near Real-Time Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multimedia file sharing technologies fail to achieve near real-time sharing and transparent transmission/receiving across different multimedia players with various formats, as existing methods either prioritize streaming over real-time delivery or require complex modifications to meet diverse streaming protocols.
Innovation Solution
A virtual multimedia file system is established that slices multimedia files into segments, generates a metafile for sequential transmission and playback, allowing for near real-time sharing and transparent compatibility with different multimedia players without the need for additional software modifications, utilizing a network bandwidth detection mechanism to optimize data distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If streaming transmission is used to share multimedia files, then near real-time playback is achieved, but the system requires complex streaming protocols and container formats that different multimedia players cannot transparently support
Solution Approach 1:
The patent divides the multimedia file into multiple data blocks and creates a segmented file structure. Each block is independently addressable through the segmented file, allowing players to access specific portions without requiring complex streaming protocols. This segmentation enables efficient random access while maintaining simplicity in the file format.
Solution Approach 2:
The patent introduces a segmented file as an intermediary layer between the original multimedia file and the multimedia player. This segmented file contains block address information that mediates the access between the player and the actual data blocks, simplifying the interface while enabling efficient playback and random access.
2Adaptability or versatility
If file transmission methods are used to share multimedia files, then transparent transmission across different players is achieved, but near real-time playback cannot be realized as users must wait for complete file download
Solution Approach 1:
The patent segments the multimedia file into multiple data blocks and creates a segmented file structure with block address information. This allows players to request and receive only the necessary data blocks for playback rather than waiting for the entire file, achieving near real-time playback while maintaining compatibility with standard file-based players.
Solution Approach 2:
The patent performs preliminary segmentation of the multimedia file into standardized data blocks and creates the segmented file structure in advance. This preliminary action organizes the data so that players can immediately access required blocks without waiting for sequential file transmission, enabling near real-time playback while maintaining simple file-based compatibility.
3Ease of manufacture
If traditional file sharing is used, then no modifications to multimedia players are needed, but users cannot start playback until the entire file is downloaded
Solution Approach 1:
The patent segments the multimedia file into multiple data blocks and creates a segmented file with block address information. This segmentation allows players to download and playback only the necessary blocks in sequence rather than waiting for the entire file, significantly improving startup speed while maintaining compatibility with existing players through a simple file-based interface.
Solution Approach 2:
The patent performs preliminary segmentation and organization of data blocks before transmission. This preliminary action creates a structured segmented file that enables players to immediately begin downloading and playing back the first data block without waiting for complete file transmission, thereby improving productivity while requiring no player modifications.
Data Source
AI summary
A multimedia file sharing method and a system thereof are provided herein, which applies the virtual file technology to achieve near real time multimedia sharing and transparent receiving functions. In the method, an interface software system is established through a network to speed up playing of multimedia files by different multimedia players. The interface software provides a speeding up and near real time multimedia playing effect for sharing multimedia through the network, by which for different transmissions of multimedia files or for playing multimedia files with different formats, the multimedia player is not necessary to modify or add the software of the players to meet the streaming protocols or container. In addition, the interface software is capable of providing the effect of playing the multimedia files by the players with satisfied quality and near real time performance.
