Signal Transfer Architecture Using Compressed and Delta Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, there is a trade-off between signal quality and bandwidth efficiency, with high-quality signals requiring high bandwidth and efficient bandwidth usage resulting in lower quality signals.
Innovation Solution
A signal transfer architecture that includes a transmit-side device generating a combined signal from first and second signals, where the first signal is compressed and the second signal represents the difference between the original and compressed signals, allowing for efficient bandwidth usage while maintaining lossless information transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high-quality signal transfer is implemented, then signal quality is improved, but bandwidth usage increases
Solution Approach 1:
The signal is divided into two separate signals: a compressed signal containing the majority of information and a delta signal containing only the differences. This segmentation allows the system to transmit essential information efficiently while adding only minimal additional data for quality restoration, resolving the contradiction between signal quality and bandwidth usage.
Solution Approach 2:
The delta signal is nested within the compressed signal structure, where the delta signal represents the difference between the original and compressed signals. This nesting approach allows the system to maintain high signal quality by combining the efficient compressed signal with the supplemental delta information, achieving quality restoration without proportional bandwidth increase.
2Quantity of substance
If bandwidth efficiency is optimized, then bandwidth usage is reduced, but signal quality deteriorates
Solution Approach 1:
The system performs preliminary compression of the original signal to create a compressed signal that captures the essential information. This preliminary action reduces bandwidth usage significantly, and the subsequent addition of the delta signal (representing differences) restores quality without requiring the full original bandwidth, thus resolving the contradiction.
3Quantity of substance
If compressed signal is transmitted, then bandwidth efficiency is improved, but information loss occurs
Solution Approach 1:
The delta signal acts as feedback information that captures the differences between the original and compressed signals. By transmitting this feedback and combining it with the compressed signal at the receiver, the system restores the original signal without information loss, thus resolving the contradiction between bandwidth efficiency and information integrity.

AI summary
A signal transfer architecture can include a transmit-side device configured to provide first and second signals from an original signal, and to transmit a combined signal including signals representative of the first and second signals. The architecture can further include a receive-side device configured to receive the combined signal and provide a reconstructed signal based on the received combined signal, such that the reconstructed signal is representative of the original signal. In some applications, the original signal can include a plurality of data frames each containing respective information, the first signal can include a compressed signal, and the second signal can include a delta signal representative of a difference between the original signal and the compressed signal.
