Transmission Processing Apparatus Dynamic Frame Rate Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for transmitting image data from multiple imaging apparatuses face challenges in efficiently managing bandwidth due to dynamic changes in foreground images, leading to inconsistent bandwidth requirements.
Innovation Solution
A transmission processing apparatus is introduced, featuring a generation unit, a transmission and reception processing unit, and a determination unit. This apparatus generates data for transmission based on captured images, determines whether to transmit data in a sequential or parallel manner depending on the type of data, and adjusts transmission based on the 'Time to Live' field and sequential transmission enablement flags.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If image data is transmitted using fixed frame frequency, then transmission timing is simplified, but bandwidth efficiency deteriorates due to dynamic changes in foreground images
Solution Approach 1:
The patent applies dynamics by making the transmission frame frequency variable rather than fixed. The determination unit dynamically adjusts the frame frequency based on the degree of change detected in foreground images. When foreground objects move significantly, the system increases transmission frequency to maintain quality; when changes are minimal, it reduces frequency to conserve bandwidth. This dynamic adaptation resolves the contradiction between operational simplicity and bandwidth efficiency.
2Manufacturing precision
If all image data is transmitted at high frame frequency, then image quality is maintained, but bandwidth consumption increases
Solution Approach 1:
The patent applies local quality by differentiating transmission priorities between different regions of the image. The system separates foreground images (containing dynamic objects) from background images and applies different frame frequencies to each. Foreground images with high dynamic changes are transmitted at high frame frequencies to maintain quality, while background images are transmitted at lower frequencies. This regional differentiation maintains overall image quality while significantly reducing total data transmission volume.
3Loss of energy
If frame frequency is adjusted based on foreground changes, then bandwidth efficiency improves, but transmission control complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the image transmission system into distinct functional modules: a foreground extraction unit that isolates dynamic objects, a change detection unit that measures foreground variability, and a determination unit that decides transmission parameters. This modular segmentation allows the system to implement complex adaptive control through coordinated simple operations in each module, improving bandwidth efficiency while managing control complexity through functional decomposition.

AI summary
A transmission processing apparatus includes a generation unit configured to generate data to be transmitted, based on an image captured by an imaging apparatus, a transmission and reception processing unit configured to receive data transmitted from a second transmission processing apparatus which is in cascade connection to the transmission processing apparatus and to transmit the received data, and a determination unit configured to determine, depending on a type of the data transmitted from the second transmission processing apparatus, whether to transmit the data generated by the generation unit in an order corresponding to the cascade connection or transmit the data generated by the generation unit in parallel with the data transmitted from the second transmission processing apparatus.
