Video Content Resolution Adaptation for Network Traffic Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video content retrieval methods from photographic devices to user terminals often result in high network traffic and costs due to the need for high-resolution video transmission, which can be inefficient and costly, especially when users want to view specific moments or periods of video content with higher resolution than what is displayed.
Innovation Solution
A method and apparatus that allow users to select a lower resolution for video content display on user terminals, either manually or automatically based on communication mode, while obtaining higher resolution images or videos corresponding to specific timestamps from photographic devices, reducing network traffic and costs by converting video content to match the selected resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high-resolution video content is transmitted from photographic device to user terminal, then video quality is improved, but network traffic and costs increase
Solution Approach 1:
The patent applies local quality by transmitting high-resolution video content only for specific time segments that users are interested in, while transmitting lower-resolution content for other segments. This allows the system to provide high video quality locally (at interested moments) without unnecessarily increasing overall network traffic.
Solution Approach 2:
The system dynamically adjusts the resolution of video content transmitted to the user terminal based on user interactions and interests. When users indicate interest in specific time segments, the system transitions from transmitting low-resolution content to high-resolution content for those segments, optimizing the balance between video quality and network traffic.
2Manufacturing precision
If high-resolution video content is transmitted, then video quality is improved, but transmission speed decreases
Solution Approach 1:
The patent implements local quality by transmitting high-resolution video content only for specific time segments where users show interest, rather than transmitting high-resolution content for the entire video duration. This selective approach maintains high video quality for important segments while improving overall transmission speed.
Solution Approach 2:
The system transmits video content at a resolution that is partially sufficient for general viewing (lower resolution) but provides high-resolution content only when needed (excessive action at specific moments). This partial approach to high-resolution transmission optimizes transmission speed while maintaining quality where necessary.
3Manufacturing precision
If high-resolution video content is transmitted, then video quality is improved, but network costs increase
Solution Approach 1:
The patent applies local quality by providing high-resolution video content only for specific time segments that users are interested in, rather than transmitting high-resolution content throughout. This reduces unnecessary network costs while maintaining high video quality where users actually need it.
Solution Approach 2:
The system enables users to indicate their interest in specific time segments of the video, allowing the system to self-adjust and transmit high-resolution content only when and where users actually need it. This user-driven approach optimizes network cost efficiency while maintaining video quality on demand.

AI summary
The present disclosure refers to a method and an apparatus for obtaining a video content. The method comprises: receiving (S201, S307) a first operation for obtaining a content in the video content displayed on the user terminal; generating (S202, S308) a first request for obtaining the content according to the first operation, in which the first request comprises a time stamp and is configured to request for an image or a video corresponding to the time stamp from a photographic device photographing the video content; sending (S203, S309) the first request to the photographic device; and obtaining (S204, S310) the image or the video corresponding to the time stamp from the photographic device, in which a resolution of the image or the video from the photographic device is higher than a resolution of the video content displayed on the user terminal.
