Parallel Video Transmission via Spatial Frame Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video transmission techniques degrade the continuity and real-time property of video on the reception-side when there is no margin in communication bandwidth, leading to inefficient use of the video.
Innovation Solution
A video transmission technique that spatially separates an image of one frame into multiple separate images and transmits them in parallel via multiple communication lines, ensuring continuity and real-time video delivery while minimizing communication costs.

Engineering Contradiction Analysis
1Quantity of substance
If basic frames are preferentially transmitted and differential frames are transmitted only when bandwidth margin is available, then communication bandwidth utilization is improved, but video continuity and real-time property are degraded
Solution Approach 1:
The patent divides a single video frame into multiple separate images (first separate image, second separate image, etc.) and transmits them through different communication lines. This segmentation allows the transmission system to send multiple frame components simultaneously, ensuring video continuity even when bandwidth is limited, while still utilizing available bandwidth efficiently.
Solution Approach 2:
The patent transitions from transmitting frames sequentially through a single communication channel to transmitting multiple frame components in parallel through multiple communication lines. This dimensional change from one-dimensional sequential transmission to multi-dimensional parallel transmission resolves the contradiction between bandwidth utilization and video continuity.
2Loss of energy
If redundant data transmission is avoided to reduce communication costs, then communication cost is reduced, but video transmission reliability under bandwidth constraints is worsened
Solution Approach 1:
By segmenting frames into multiple separate images transmitted through different communication lines, the system avoids redundant transmission of complete frames while ensuring that at least some frame components arrive reliably. This segmentation strategy reduces communication costs by eliminating redundancy while maintaining transmission reliability through diversification across multiple lines.
Solution Approach 2:
The patent changes the transmission parameter from sending complete frames or simple differential frames to sending segmented frame components (separate images) with different importance levels. This parameter change allows the system to optimize communication cost by transmitting only essential frame portions when bandwidth is constrained, while maintaining reliability through the segmented structure.

AI summary
A communication device transmits a video to a reception-side device connected via N communication lines. N is an integer of 2 or more. The communication device includes a controller. The controller spatially separates an image of one frame into N separate images. Then, the controller transmits the N separate images to the reception-side device in parallel via the N communication lines, respectively.
