Integrated Video Router Audio Mixing to Cut Cabling and Footprint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video router architectures require separate, outboard audio mixers, which limit audio mixing capabilities, increase cost, physical footprint, and require additional cabling, leading to inefficiencies and potential errors.
Innovation Solution
Integrate audio mixing and processing capabilities within a video router using a Field Programmable Gate Array (FPGA)-based architecture with Time-Division Multiplexed (TDM) internal audio architecture, allowing for flexible partitioning and selective reordering of audio signal processing operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate outboard audio mixers are used for audio signal mixing, then audio signal processing capability is provided, but device complexity and physical footprint increase
Solution Approach 1:
The patent integrates the audio mixing subsystem directly into the video router device, combining previously separate audio and video routing functions into a single integrated unit. This eliminates the need for external outboard audio mixers while maintaining full audio signal processing capability, thereby reducing device complexity and physical footprint.
Solution Approach 2:
The video router is designed to perform multiple functions including both video signal routing and audio signal mixing/processing within the same device. This multi-functional approach allows the single device to replace what previously required separate specialized equipment, reducing overall system complexity.
2Adaptability or versatility
If separate outboard audio mixers are used, then audio mixing function is provided, but installation complexity and cabling requirements increase
Solution Approach 1:
By integrating the audio mixing subsystem within the video router, the patent eliminates the need for separate physical connections between video routing equipment and external audio mixers. This consolidation simplifies installation by reducing the number of cables and connections required while maintaining full audio mixing functionality.
3Adaptability or versatility
If external audio mixers are used, then audio processing capability is provided, but cost increases
Solution Approach 1:
The integration of audio processing capabilities into the video router eliminates the need to purchase and install separate outboard audio mixer equipment. This consolidation reduces overall system cost by replacing multiple separate devices with a single integrated unit that provides both video routing and audio processing functions.

AI summary
Video routing may include integrated audio mixing, audio processing, or both. An audio subsystem that is integrated with a video router, for example, may receive and mix router input audio signals to provide mixed audio signals, and route the mixed audio signals to router outputs as router output audio signals. Regarding audio processing, input audio signals that include router input audio signals that are received by the video router may be routed as output audio signals. The output audio signals include router output audio signals to be output from the video router. Respective ones of the output audio signals are processed to provide respective processed output audio signals. The input audio signals for the routing also include the processed output audio signals.
