Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video network adaptation technologies fail to balance video definition and smoothness effectively due to the lack of consideration for the image super-resolution capability of terminals, leading to suboptimal video display quality.
Innovation Solution

Engineering Contradiction Analysis
1Speed
If video network adaptation technology adjusts frame rate and resolution based on network status, then video smoothness is improved, but video definition cannot be optimized because terminal super-resolution capability is not considered
Solution Approach 1:
The patent makes the video transmission system dynamic by adapting the base resolution and frame rate based on both network status and terminal super-resolution capability. The sending device dynamically adjusts transmission parameters according to real-time conditions, enabling optimal balance between smoothness and definition for each specific scenario.
Solution Approach 2:
The patent changes key parameters including base resolution, frame rate, and super-resolution multiplier based on network status and terminal capabilities. By varying these parameters adaptively, the system optimizes both video smoothness during transmission and video definition at the receiving end.
2Manufacturing precision
If high resolution video is transmitted to ensure video definition, then video quality is improved, but network bandwidth consumption increases affecting smoothness
Solution Approach 1:
The patent applies partial action by transmitting only the necessary base resolution video stream and relying on terminal super-resolution to provide the additional definition. This avoids transmitting excessive data while still achieving high definition output, thus conserving network bandwidth while maintaining video quality.
Solution Approach 2:
The terminal's super-resolution algorithm acts as an intermediary that enhances the transmitted video signal. Instead of transmitting high-definition video directly, the system transmits a lower-resolution stream that is then enhanced by the terminal's processing capabilities, reducing network bandwidth requirements while maintaining definition.
3Productivity
If video resolution is reduced to save network bandwidth, then network efficiency is improved, but video definition deteriorates unless super-resolution is applied
Solution Approach 1:
The patent performs preliminary action by having the terminal prepare and indicate its super-resolution capability before video transmission begins. The sending device uses this advance information to optimize transmission parameters, ensuring that definition is preserved through the combination of adaptive transmission and pre-configured terminal enhancement.
Solution Approach 2:
The patent substitutes mechanical transmission of high-definition video data with a combination of lower-resolution transmission plus computational super-resolution enhancement. This replaces the traditional approach of transmitting all definition information directly with a more efficient computational approach.
4Manufacturing precision
If terminal super-resolution capability is utilized to enhance video definition, then video quality is improved, but device processing requirements increase
Solution Approach 1:
The patent applies local quality by having different devices with different super-resolution capabilities receive appropriately optimized video streams. The sending device tailors the base resolution and transmission parameters to match each terminal's specific processing capabilities, ensuring optimal definition enhancement without overburdening any particular device.
Solution Approach 2:
The terminal serves itself by using its own super-resolution capability to enhance the received video stream. Each terminal independently processes the incoming video according to its own capabilities, without requiring external processing assistance, thus managing processing complexity autonomously.

AI summary
Embodiments of the present invention disclose a video adaptation method, a related device, and a storage medium. The method in the embodiments of the present invention includes: receiving indication information sent by a video receiving device, where the indication information is used to indicate an image super-resolution capability of the video receiving device; and if the indication information indicates that the image super-resolution capability of the video receiving device is enabled, obtaining a video having a target frame rate and a target resolution that correspond to the indication information, and sending the video having the target frame rate and the target resolution to the video receiving device. It can be learned that the video having the target frame rate and the target resolution matches the image super-resolution capability of the video receiving device, and the video receiving device may display the video whose definition and smoothness are balanced. Therefore, it is ensured that the video receiving device displays the high-definition video, and the smoothness of displaying the video is also effectively ensured.
