Solution Overview

Problem

Satellite data delivery is prone to outages due to adverse weather conditions like rain, leading to reliability issues, particularly for mission-critical data, where disruptions can be undesirable even if short-term.

Innovation Solution

Implementing data distribution schemes that provide redundancy by segmenting, replicating, and interleaving data across multiple satellites and transponders, allowing for recovery of lost data and maintaining reliability even if an entire satellite or transponder is lost.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If data is transmitted via satellite, then data delivery is achieved, but reliability deteriorates due to rain fade and adverse weather conditions

Engineering Contradiction:
Improvedata delivery reliabilityVSAvoidrain fade
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The data stream is divided into multiple segments that are distributed across different satellites and transponders. Each segment contains a portion of the original data, and the system can reconstruct the complete data set by collecting enough segments from available sources, even when some transmission paths are blocked by rain fade.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates multiple copies of data segments and distributes them across different satellites and transponders. This redundancy ensures that if one transmission path is blocked by adverse weather, identical or complementary data copies can be retrieved from alternative paths to maintain delivery reliability.

Inventive Principle:
Principle #26Copying

2Reliability

If redundant data distribution is implemented across multiple satellites, then reliability is improved, but device complexity increases

Engineering Contradiction:
Improvedata delivery reliabilityVSAvoiddata distribution system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system design allows standard satellite transponders and receiving equipment to serve multiple purposes: normal data transmission and redundant data storage. The same infrastructure is used for both primary and backup data paths, reducing the need for specialized complex equipment while maintaining reliability through multi-functional resource utilization.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A media device may be configured for receiving data from one or more satellites. The media device may include one or more processors and one or more storage devices. A first tuner of a media device may tune to a first data stream that came from a first satellite transponder. A second tuner of the media device may tune to a second data stream that came from a second satellite transponder. The first data stream and the second data stream may be derived from source data based at least in part on a data distribution scheme. The data distribution scheme may include distributing at least portions of the source data with the first data stream and the second data stream. The first data stream and/or the second data stream may be processed to store and/or output for presentation content.
