Character Restoration Encoding for Cloud Text Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for data transmission in cloud computing and virtual desktops face inefficiencies due to excessive data flows caused by lossless compression based on pixel information of text, leading to slow data transmission and display stuttering.
Innovation Solution
A character restoration method that determines a unique character identifier, encodes it, and sends it to the receiving end for decoding, allowing for the restoration of characters using minimal information, thereby reducing data flow and improving transmission efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lossless compression based on pixel information is used, then text can be transmitted without loss, but excessive data flows are generated causing slow transmission and display stuttering
Solution Approach 1:
The text region is segmented into multiple character elements, where each character is identified and encoded separately using character identifiers rather than transmitting complete pixel information for each character, thus reducing data flow while maintaining text accuracy
Solution Approach 2:
Only the essential character identifier information is extracted and transmitted from the complete character data, eliminating redundant pixel information while preserving the ability to restore characters at the receiving end
2Productivity
If character identifier encoding is used, then data flow size is reduced, but the receiving end must decode and restore characters which adds processing complexity
Solution Approach 1:
Character identifier encoding rules and character element information are pre-established and synchronized between sending and receiving ends before transmission begins, allowing the receiving end to efficiently decode and restore characters without complex real-time processing

AI summary
A character restoration method and apparatus, a storage medium, and an electronic device are provided. The character restoration method includes: a character identifier of a character in a text region is determined, where the character identifier is used for uniquely identifying the character; and encoding is performed at least according to the character identifier, and encoded data is sent to a receiving end, where the encoded data is used for the receiving end to decode the encoded data and restore the character according to the character identifier obtained after decoding, that is, encoding is performed merely according to a small amount of information, and then the information is obtained by decoding, so as to restore the character.
