Cloud Multimedia File Handling via HTTP HEAD Checks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile communication systems face bandwidth constraints and unnecessary multimedia file downloads, limiting the ability to efficiently transfer and display multimedia content across different devices and networks.
Innovation Solution
A technique that uses a cloud-hosted multimedia file handling system, where a link to the multimedia file is received, and an HTTP HEAD command is used to determine the file type and support, avoiding unnecessary downloads by only processing files that can be displayed or rendered on the device, and allowing for spam detection based on file size and ETag analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multimedia files are downloaded to mobile devices, then content availability is improved, but network bandwidth consumption increases
Solution Approach 1:
The system performs preliminary actions by checking device compatibility and file support status before initiating full multimedia file downloads. The server sends metadata about supported file types and formats in advance, allowing the mobile device to determine whether it can handle the incoming content, thereby avoiding unnecessary bandwidth consumption for incompatible files.
Solution Approach 2:
The patent introduces an intermediary layer between the multimedia server and mobile device - a compatibility checking mechanism that acts as a mediator. This intermediary verifies file type support, checks device capabilities, and filters content before full transmission, preventing direct download of incompatible files and thus reducing network bandwidth usage.
2Adaptability or versatility
If all multimedia file types are downloaded, then content compatibility is improved, but network efficiency deteriorates
Solution Approach 1:
The system applies partial action by downloading only the necessary metadata and compatibility information rather than complete multimedia files. The server transmits file type identifiers, format specifications, and support status indicators - just enough information to determine compatibility - without performing the excessive action of downloading entire files that may not be supported by the device.
3Speed
If multimedia files are pre-downloaded, then access speed is improved, but network bandwidth usage increases
Solution Approach 1:
The patent extracts only the essential compatibility-determining elements from multimedia files - specifically file type metadata, format information, and support status indicators. By taking out just these critical components rather than entire files, the system enables quick compatibility verification and prevents bandwidth-wasting downloads of unsupported content types.
Data Source
AI summary
A method for handling a cloud hosted multimedia file on mobile devices includes receiving a message with a link to multimedia file, extracting the link and determining an address of multimedia server, contacting the multimedia server to determine a file type and determining whether the file type is supported.
