Local Audio Video Processing for Bandwidth Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current remote video conferencing technologies are costly and require high maintenance, with video fusion capabilities that are limited due to reliance on cloud-based image and audio processing, leading to poor performance and high bandwidth usage.
Innovation Solution
A processing method and device that locally process and compress audio and video data, enabling video fusion and reducing reliance on cloud processing by transmitting processed data of varying sizes directly to target applications on connected devices, thereby improving conferencing smoothness and reducing bandwidth occupancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cloud-based image and audio processing is used, then video conferencing can be implemented, but the cost is high and maintenance is complex
Solution Approach 1:
The patent extracts the image and audio processing functions from the cloud-based system and relocates them to local electronic devices. Each device performs processing independently using local processors, eliminating the need for centralized cloud processing infrastructure and reducing system maintenance complexity.
Solution Approach 2:
Each electronic device is equipped with local processing capabilities that enable it to independently process its own audio and video data without relying on external cloud services. This self-service approach allows devices to autonomously perform processing tasks, reducing dependency on complex centralized infrastructure.
2Reliability
If cloud-based processing is used, then video conferencing can be implemented, but video fusion cannot be realized
Solution Approach 1:
The patent segments the video conferencing system into independent processing units, where each electronic device processes its own audio and video streams locally. This segmentation enables flexible combination of multiple video streams through video fusion, as each device can independently process and contribute to the fused output without cloud-based constraints.
3Ease of manufacture
If independent transmission of video and audio streams is used, then simple processing can be achieved, but bandwidth usage is high
Solution Approach 1:
The patent merges the transmission of audio and video data by having electronic devices process and transmit combined or selectively prioritized data streams. Instead of transmitting all raw audio and video data independently, the system combines processing operations and transmits only necessary processed data, reducing overall bandwidth occupancy while maintaining processing simplicity.
4Reliability
If high-quality image and audio processing is performed, then conferencing quality improves, but data size increases
Solution Approach 1:
The patent applies local quality processing where each electronic device processes its own audio and video data to the required quality level locally before transmission. This approach maintains high conferencing quality through local processing while reducing the overall data size that needs to be transmitted across the network, as each device handles only its own data stream at full quality.
Data Source
AI summary
A processing method applied to a first electronic device, the method including obtaining first audio data and/or first image data; performing at least one process on the first audio data and/or the first image data to obtain target data to be outputted; and outputting the target data to be outputted to a target application running on a second electronic device having a communication connection with the first electronic device. The target application is configured to directly output the target data to be outputted. The data size of the target data to be outputted is different from data size of the first audio data and/or the first image data.
