Solution Overview
Problem
Remote applications face challenges in normal interaction during rich media situations due to high network bandwidth occupancy, affecting user experience, as existing solutions like content redirection and transport layer optimization are inadequate in managing network bandwidth effectively.
Innovation Solution
A traffic controlling method and device that evaluates current network bandwidth, detects bitmap updating frequency, and identifies valid multimedia areas to dynamically control data traffic by filtering non-critical contents or performing multi-frame merging and compression, ensuring unblocked transmission of critical business and maintaining display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screen updating information is transmitted to client side as images in RAPP technology, then safer data transmission and simpler deployment are achieved, but network bandwidth is almost completely occupied which affects normal interactions
Solution Approach 1:
The patent segments the screen image into multiple regions (valid multimedia areas and invalid areas) based on bitmap updating frequency. Different regions are processed differently: valid multimedia areas are transmitted at high quality while invalid areas are compressed or skipped, thereby reducing overall bandwidth occupancy without sacrificing critical display quality.
Solution Approach 2:
The patent applies local quality optimization by detecting which screen regions have high bitmap updating frequency (valid multimedia areas) and which have low frequency (invalid areas). The system then adjusts transmission quality locally - high quality for valid areas, compressed or omitted for invalid areas - optimizing the balance between display quality and bandwidth efficiency.
2Ease of operation
If content redirection technology is used to transmit videos or animations in original coded formats, then client side decoding and rendering is achieved, but high performance requirements are placed on client side and network bandwidth occupancy increases for low resolution videos
Solution Approach 1:
The patent extracts only the critical information (valid multimedia areas with high bitmap updating frequency) from the overall screen content and prioritizes their transmission. Non-critical areas (invalid areas with low updating frequency) are compressed or omitted, reducing the total data volume transmitted while maintaining client-side rendering capability for essential content.
3Speed
If transport layer protocol acceleration technology is used to optimize TCP congestion control or replace with UDP, then transmission speed is improved, but network bandwidth cannot be reduced and improvement space is limited
Solution Approach 1:
The patent dynamically adjusts the transmission strategy based on real-time detection of valid and invalid multimedia areas. The system adaptively selects which regions to transmit at full quality and which to compress or skip, dynamically optimizing the balance between transmission speed and bandwidth usage rather than relying solely on fixed protocol optimizations.
4Object-generated harmful factors
If frame rates are limited to reduce bandwidth, then network bandwidth is reduced, but user experience decreases due to inability to optimize data in real multi-media screen areas independently
Solution Approach 1:
The patent segments the screen into valid and invalid multimedia areas based on bitmap updating frequency. By processing different regions independently with different quality levels, the system maintains high frame rates and user experience for critical valid areas while reducing bandwidth for invalid areas, overcoming the limitation of uniform frame rate restriction.

AI summary
The present disclosure provides a traffic controlling method based on remote applications, comprising the following steps: evaluating a current network bandwidth; detecting a bitmap updating frequency of each area in a current screen, identifying a multimedia area, and judging whether the multimedia area is valid or not to obtain a judging result; and controlling data traffic according to the current network bandwidth and the judging result. By evaluating the current network bandwidth, detecting the updating frequency of each area in the current screen and identifying whether the multimedia area is valid, and dynamically controlling the data traffic according to the current network bandwidth and according to whether the multimedia area is valid, the present disclosure is capable of ensuring the unblocked transmission of the critical business and preventing the display quality of the multimedia area from being affected to improve the system performance and the user experience.
