Video Frame Segmentation for Transmission Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-resolution video data files require longer times for transmission and processing due to increased file sizes, leading to undesirable delays in broadcasting and file operations.
Innovation Solution
The method involves splitting each frame of video data into partial resolution layers, with a base frame layer and additional layers transmitted based on priority information, allowing for adaptive frame rates and resolution adjustments to optimize transmission efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high-resolution video data is transmitted without splitting, then video quality is maintained, but transmission time increases significantly
Solution Approach 1:
The patent divides each video frame into multiple partial resolution layers (base layer and additional layers). The base layer contains essential low-resolution information that can be transmitted quickly, while additional layers contain incremental high-resolution details. This segmentation allows progressive transmission where the receiver can reconstruct video at different quality levels based on available bandwidth and time, resolving the contradiction between maintaining high resolution and reducing transmission time.
2Ease of operation
If complete video files are broadcast for file modification operations, then editing capabilities are enabled, but processing time increases
Solution Approach 1:
The patent performs preliminary processing by splitting video frames into hierarchical resolution layers before transmission. This preliminary action enables the receiver to access and modify specific layers (such as the base layer) without waiting for or processing the complete high-resolution video file. Users can perform file modification operations on lower-resolution representations more quickly, reducing processing time while maintaining the capability to edit video content.
3Speed
If additional frame layers are transmitted at higher frame rates, then video smoothness is improved, but data transmission volume increases
Solution Approach 1:
The patent applies different frame rates to different resolution layers based on their specific requirements. The base layer, which provides the essential video content, can be transmitted at a lower frame rate. Additional layers that enhance detail and smoothness can be transmitted at higher frame rates, but only where and when needed. This local quality approach optimizes the balance between video smoothness and data transmission volume by allocating bandwidth differentially across layers rather than uniformly.

AI summary
Various aspects of a system and a method for transmitting data are disclosed herein. The method is included in a first electronic device. The first electronic device splits each frame of the video data into a plurality of partial resolution layers. The plurality of partial resolution layers comprises a base frame layer and one or more additional frame layers. The base frame layer and the one or more additional frame layers of frame of the video data are transmitted to a second electronic device.
