Network Font Management for Imaging Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging devices often struggle to present assets such as documents and web pages due to missing fonts, leading to suboptimal viewing experiences and inefficient memory usage, as they may not have the necessary font resources or bandwidth to handle complete font sets, especially for languages with thousands of characters.
Innovation Solution
A system and method that identifies the necessary font information for an imaging device by analyzing attributes of the asset and environmental characteristics, providing font subsets instead of complete font sets to conserve memory and reduce bandwidth, and automatically requesting and delivering the required font information without user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complete font sets are provided to imaging devices, then font presentation capability is improved, but memory usage and bandwidth consumption increase
Solution Approach 1:
The patent segments complete font sets into font subsets based on the actual character content of assets. Instead of providing entire font families, the system analyzes the asset's text content and delivers only the specific character subsets needed, thereby reducing memory usage while maintaining font presentation capability.
Solution Approach 2:
The patent extracts and delivers only the necessary font information required for presenting specific assets. The system identifies and extracts the minimal font subset needed from complete font sets, transferring only those characters that actually appear in the asset content, thus reducing bandwidth and memory requirements.
2Reliability
If complete font sets are transferred over the network, then font availability is improved, but bandwidth consumption increases
Solution Approach 1:
The patent segments font data into smaller, asset-specific subsets before transfer. By dividing complete font sets into character-based subsets, the system reduces the amount of data transmitted over the network while ensuring font availability for the specific content being presented.
Solution Approach 2:
The patent applies partial action by transferring only the necessary portion of font data required for asset presentation. Instead of transferring complete font sets, the system transfers partial font subsets that contain only the characters actually needed, reducing bandwidth consumption while maintaining sufficient font availability.
3Measurement precision
If font information is manually provided by users, then font delivery accuracy is improved, but user experience and efficiency worsen
Solution Approach 1:
The patent implements self-service by enabling the imaging device to automatically request and receive font subsets without user intervention. The system autonomously analyzes asset content, identifies missing fonts, requests appropriate font subsets from remote servers, and delivers them, thereby maintaining font delivery accuracy while significantly improving user experience.
Solution Approach 2:
The patent applies preliminary action by having the imaging device automatically detect font requirements and initiate font subset requests before asset presentation. This automated preliminary font preparation eliminates the need for manual user configuration while ensuring accurate font delivery.
Data Source
AI summary
A system includes a computing device that includes a memory configured to store instructions. The computing device also includes a processor to execute the instructions to perform operations that include receiving a request from an imaging device indicating that the imaging device is unable to present textual content of an asset. The request includes one or more attributes of the textual content of the asset and the request is sent from the imaging device absent user input. Operations also include identifying an appropriate amount of font information from the received one or more attributes for the imaging device to present the asset, and, providing the identified font information to the imaging device for presenting the asset.
