Multipath Router Video Encoding for High-Definition Streaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless networks, including 4G LTE, struggle to reliably transmit high-definition video from mobile devices due to capacity limitations and fluctuations, especially in crowded areas where multiple devices compete for limited resources, leading to issues like data loss, corruption, and delayed streams.
Innovation Solution
The implementation of multipath wireless routing technology, which splits audio and video data into multiple streams and dynamically adjusts encoding based on network feedback, allowing data to be transmitted over multiple network connections, prioritizing reliable and low-latency paths to minimize data loss and ensure continuous, high-quality video transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is transmitted over a single wireless network connection, then the system complexity is low, but the reliability and throughput are insufficient for high-definition video transmission
Solution Approach 1:
The patent segments the video data stream into multiple parallel streams, each transmitted over a different wireless network connection. The video encoder divides the encoded video data into multiple data streams that are sent simultaneously through multiple network interfaces, improving reliability by distributing the transmission load across multiple paths.
Solution Approach 2:
The patent combines multiple wireless network connections into a unified transmission system. Multiple network interfaces (e.g., Wi-Fi, cellular, Bluetooth) are merged to work together as a single multi-path transmission system, aggregating their combined bandwidth and reliability to enable robust high-definition video transmission.
2Reliability
If video data is transmitted in real-time without buffering, then the latency is low, but data loss and corruption occur more frequently under network fluctuations
Solution Approach 1:
The patent implements buffering at the receiver side to cushion against network fluctuations. The receiver buffer stores incoming data packets temporarily, allowing the system to recover from packet loss and re-synchronize video and audio streams without immediate failure, providing a time cushion that improves error resilience.
Solution Approach 2:
The patent employs feedback mechanisms where the receiver monitors transmission quality and sends feedback signals to the transmitter. This feedback loop allows the system to detect data loss, adjust encoding parameters, and retransmit corrupted packets, thereby improving reliability while managing the associated delays.
3Productivity
If multiple network connections are used for data transmission, then the throughput and reliability improve, but the device complexity and routing difficulty increase
Solution Approach 1:
The patent introduces a multipath router as an intermediary device that manages the complexity of multiple network connections. The router receives video data from the mobile device and automatically distributes it across multiple available network paths, handling the routing complexity centrally rather than requiring complex routing logic in each transmitting device.
Solution Approach 2:
The patent implements self-service routing mechanisms where the system automatically selects and manages optimal transmission paths without manual intervention. The multipath routing algorithm dynamically monitors network conditions and autonomously adjusts data distribution across connections, reducing the operational complexity for users.
4Productivity
If video and audio streams are transmitted separately, then the synchronization is easier to maintain, but the overall transmission efficiency decreases
Solution Approach 1:
The patent merges video and audio streams into a single integrated data transmission process. Both video and audio data are encoded together, packetized with synchronized timestamps, and transmitted as unified data streams through the same network paths, improving transmission efficiency while maintaining synchronization through embedded timing information.

AI summary
There is disclosed a system and method for transmission of multiple data streams from a mobile device to a network. In an embodiment, the system includes a multipath wireless router configured to provide a plurality of network connections including cellular, satellite, or wired Ethernet. An encoding module provided on the mobile device is configured to encode high volume data (e.g. high definition video) recorded by the mobile device into multiple data streams in dependence on the number of network connections available for transmission via the multipath wireless router. The encoding module provided on the mobile device transmits the multiple data streams to the wireless router using Wi-Fi to provide a local, short-hop, high capacity network connection.
