Wireless Lost Content Segment Retrieval via Device Network
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices receiving satellite signals often experience lost content segments due to obstructions like trees or buildings, disrupting the video stream and frustrating users.
Innovation Solution
A method utilizing a terrestrial communication network to retrieve and provide lost content segments by forming a network of nodes, where a mobile user device requests and receives missing content from another node within the network, ensuring continuous signal delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mobile devices use satellite signals for content delivery, then content distribution is achieved, but obstructions cause lost content segments
Solution Approach 1:
The patent introduces intermediary devices (set-top boxes, mobile devices with recording capability) that act as mediators between the satellite signal source and the end user. When obstructions block the direct satellite signal, these intermediary devices store the content locally and provide it to other users who experience signal loss, thereby resolving the reliability issue caused by obstructions.
Solution Approach 2:
The system performs preliminary action by having intermediary devices record and store content segments in advance when the signal is available. This pre-stored content is then available for retrieval when obstructions cause signal loss, ensuring continuous content delivery without interruption.
2Ease of operation
If content is stored locally at user devices, then access to content is improved, but lost segments cannot be recovered from obstructions
Solution Approach 1:
The patent implements feedback mechanisms where devices monitor signal quality and detect when content segments are lost due to obstructions. When loss is detected, the system automatically requests and retrieves the missing segments from other devices in the network, ensuring complete content recovery and maintaining information integrity.
Solution Approach 2:
The system merges multiple content sources (direct satellite signal, local storage, and other devices in the network) into a unified content delivery system. This combination allows the system to switch between sources and retrieve lost segments from alternative sources, preventing permanent information loss.
3Reliability
If a network of devices is formed for content sharing, then lost segments can be recovered, but device complexity increases
Solution Approach 1:
The patent enables self-service operation where devices automatically perform content retrieval and recovery without requiring manual network configuration or user intervention. The system autonomously detects lost segments, identifies appropriate sources in the network, and completes the retrieval process automatically, thereby reducing the perceived complexity for users.
Solution Approach 2:
The system implements multi-functionality where each device in the network can simultaneously act as a content receiver, storage device, and content source for others. This universal capability simplifies the overall system architecture by eliminating the need for specialized roles and reducing configuration complexity.

AI summary
A method and system includes a network having a plurality of nodes including a first mobile user device at a first node. The network also includes a second node. The system also includes a first mobile user device storing content in a memory, determining a lost content segment exists, generating a request for the lost content segment at the first mobile user device, communicating the request for the lost content to a second node of the network, receiving the lost segment from the second node and storing the lost content segment in the memory of the user device.
