Multimedia Stream Multicasting via Thin Terminal Hardware Decoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing desktop sharing solutions waste network resources and cause high CPU consumption on the receiving end, leading to inferior user experience and limited multicasting capabilities due to the need for repeated multimedia content processing and decoding by virtual machines.
Innovation Solution
A method and device for multimedia stream multicasting that allows the sending end to broadcast a multicasting address to virtual machines, which are then added to a networking address list, enabling direct decoding and playback on thin terminals, reducing resource consumption and processing load on virtual machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the receiving side uses sharing software to decode and play multimedia content in the virtual desktop system, then the multimedia content can be displayed, but the CPU of the virtual machine consumes large amounts of resources causing discontinuous playback or system failure
Solution Approach 1:
The patent extracts the multimedia decoding function from the virtual machine environment and places it in the thin terminal's hardware decoding capability. The virtual machine no longer needs to perform software decoding, which was consuming excessive CPU resources. Instead, the thin terminal directly decodes the multimedia stream received from the virtual machine, relieving the VM's CPU burden and ensuring stable playback.
Solution Approach 2:
The patent introduces a direct multimedia stream transmission path as an intermediary between the virtual machine and the thin terminal. Instead of going through the virtual desktop system's software decoding pipeline, the multimedia stream is transmitted directly to the thin terminal which has dedicated hardware decoding capabilities, acting as an intermediary that bypasses the resource-constrained virtual machine environment.
2Adaptability or versatility
If the same multimedia content is repeatedly presented in both the virtual desktop and thin terminal, then the content can be displayed in both environments, but network resources are wasted due to redundant transmission
Solution Approach 1:
The patent extracts the multimedia playback function from the virtual desktop system and implements it directly in the thin terminal. The virtual machine sends the multimedia stream directly to the thin terminal for local decoding and display, eliminating the need for the virtual desktop system to also present and retransmit the same content. This extraction of the playback function to the terminal side reduces redundant network transmissions while maintaining the ability to display content in the intended environment.
3Ease of manufacture
If the virtual machine performs software encoding and decoding of multimedia content, then the content can be processed and shared, but the processing load causes inferior user experience and limited multicasting support
Solution Approach 1:
The patent substitutes software-based encoding and decoding mechanisms with hardware-based decoding capabilities in the thin terminal. Instead of relying on the virtual machine's software processing (which is resource-intensive and affects user experience), the system uses the terminal's hardware decoding capabilities to process multimedia content efficiently, providing better user experience and supporting multicasting without excessive processing load.
