IVR Video Packet Reflection for Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Video conferencing systems face challenges when interacting with IVR systems, as the lack of video support in IVRs can lead to incorrect assumptions about video connectivity, and providing visual feedback is complicated by the need to manage various video encodings, form factors, and bit rates.
Innovation Solution
Implementing a method where IVR systems reflect back received video packets with modified headers to video endpoints, allowing them to believe they are in a video conference mode and providing visual feedback without requiring extensive processing resources, even if the IVR lacks video processing capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If IVR systems provide video support by composing new video images, then video connectivity is maintained, but processing resources are extensively consumed
Solution Approach 1:
The patent applies the copying principle by having the IVR system transmit copies of received video packets back to the video endpoint instead of composing new video images. The video packets are reflected with modified headers (swapped source and destination addresses, modified sequence numbers) while the payload remains unchanged, providing visual feedback to the endpoint without requiring extensive video processing resources.
2Device complexity
If IVR systems lack video processing capability, then device complexity is reduced, but video connectivity cannot be maintained
Solution Approach 1:
The patent applies the intermediary principle by using network infrastructure and protocol manipulation as a mediator between the IVR system and video endpoint. The IVR system acts as a passive reflector that modifies packet headers rather than processing video content, allowing video connectivity to be maintained through network-level operations without requiring the IVR to have video processing capabilities.
3Use of energy by moving object
If video packets are reflected back with modified headers, then visual feedback is provided without extensive processing, but packet manipulation complexity increases
Solution Approach 1:
The patent applies segmentation by separating the video packet into header and payload components. Only the header portion requires modification (swapping source and destination addresses, adjusting sequence numbers), while the payload remains unchanged. This segmentation allows the system to perform minimal processing on the critical header fields while preserving the integrity of the video data in the payload.
Data Source
AI summary
According to one embodiment of the invention, a method for maintaining video capability includes receiving at a device from a source a plurality of packets representative of video data. The plurality of packets include a payload and a header. The method also includes transmitting a copy of the plurality of received packets back to the source with a modified header and an unmodified payload. The transmitted copy provides data representative of the video data.
