Composite Signal Processing Extender for USB-C
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing videoconferencing systems face challenges with signal degradation due to limited USB-C cable lengths, which restricts the distance between devices and audio-visual equipment in meeting rooms, leading to reduced functionality and user discomfort.
Innovation Solution
A system and apparatus that process composite signals using a first communication protocol, isolate multiple signal components, convert them as needed, and transmit them using a second communication protocol over a longer distance, while also providing power supply signals through the same cable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If USB-C cable length is extended beyond 2 meters, then connectivity distance is improved, but signal degradation occurs
Solution Approach 1:
The patent introduces an intermediary device (signal extender or repeater) that receives the USB-C signal, regenerates it, and retransmits it. This mediator allows the signal to travel beyond the native 2-meter limit without degradation by breaking the direct cable connection into two segments with regeneration in between.
Solution Approach 2:
The patent changes the electrical parameters of the signal transmission by using active electronics in the extender device to boost signal strength, adjust impedance, and compensate for attenuation. This allows extension beyond passive cable limits while maintaining signal integrity.
2Reliability
If multiple cables are used to provide full USB-C functionality, then connectivity reliability is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple separate cable connections (data, power, video) into a single unified USB-C connection. The extender device consolidates these functions, allowing users to maintain full functionality while using only one cable physically, thus reducing complexity and improving ease of operation.
3Reliability
If USB-C cable length is limited to 2 meters, then signal quality is maintained, but ease of operation deteriorates
Solution Approach 1:
By introducing the signal extender as an intermediary, users can place the device at optimal locations without being constrained by the 2-meter cable limit. This improves ease of operation and user comfort while the intermediary ensures signal quality is maintained through active regeneration.

AI summary
In some examples, an apparatus for processing a composite signal transmitted uses a first communication protocol via a first port comprising a first connector type, in which the apparatus comprises a processor configured to execute one or more instructions stored in a memory of the apparatus, whereby to cause the apparatus to isolate multiple components of the composite signal received at a first port of the apparatus, the first port of the apparatus, whereby to generate a first and second set of signal components, process at least one component from the second set of signal components to generate a converted signal component, transmit the first set of signal components and the converted signal component from a second port of the apparatus using a second communication protocol, and receive a power supply signal over the second port of the apparatus.
