Satellite Multimedia Filtering via User Segmentation

Solution Overview

Problem

Current methods for broadcasting multimedia content via satellite face challenges such as network saturation, quality of service issues, and limited availability, especially when providing 'video on demand' services, as they often rely on unicast protocols or multicast protocols that are not adaptable to individual user preferences and diverse content demands.

Innovation Solution

A method that filters multimedia content using user-specific filters determined by a remote computation unit, based on user profiles and similarities with other users, to optimize content storage on user devices, allowing for efficient access and choice of media items, and dynamically decides between unicast and multicast transmission protocols.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If unicast protocol is used for video on demand broadcast, then each user can receive their content independently, but the network rapidly becomes saturated and quality of service is not guaranteed

Engineering Contradiction:

Improveindividual content selectionVSAvoidnetwork capacity

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The invention segments the user base into groups with similar content preferences using clustering algorithms. Instead of treating each user individually (unicast) or all users uniformly (multicast), the system divides users into segments that can be served efficiently through targeted multicast transmissions, reducing overall network load while maintaining individualized service quality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system dynamically adjusts the transmission protocol based on real-time conditions. When network capacity allows, it uses unicast for individualized content delivery; when network load increases, it transitions to multicast for group-based delivery. This dynamic adaptation optimizes network resource utilization while maintaining service quality.

Inventive Principle:

Principle #15Dynamics

2Productivity

If multicast protocol is used to broadcast one content to multiple users, then network efficiency improves, but video on demand service cannot be provided adequately

Engineering Contradiction:

Improvenetwork efficiencyVSAvoidindividual content demand

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The invention segments the user base into groups with similar content preferences using clustering algorithms. Instead of treating each user individually (unicast) or all users uniformly (multicast), the system divides users into segments that can be served efficiently through targeted multicast transmissions, reducing overall network load while maintaining individualized service quality.

When network capacity allows, it uses unicast for individualized content delivery; when network load increases, it transitions to multicast for group-based delivery. This dynamic adaptation optimizes network resource utilization while maintaining service quality.

Inventive Principle:

3Adaptability or versatility

If satellite bandwidth is increased to accommodate diverse content demands, then content availability improves, but the cost becomes high and not compatible with commercial service

Engineering Contradiction:

Improvecontent varietyVSAvoidsatellite bandwidth

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The invention segments the user base into groups with similar content preferences using clustering algorithms. Instead of treating each user individually (unicast) or all users uniformly (multicast), the system divides users into segments that can be served efficiently through targeted multicast transmissions, reducing overall network load while maintaining individualized service quality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system changes the parameter of transmission efficiency by using intelligent content selection and filtering. Instead of broadcasting all content to all users (inefficient use of bandwidth), it selectively transmits only the content relevant to each user segment, effectively increasing content variety delivery without proportionally increasing satellite bandwidth requirements.

AI summary

A method for filtering a set of contents broadcast over a satellite link includes: a first reception of a user filter by at least one piece of user equipment, the user filter including a user identifier and a first list of multimedia contents, the first list being selected from a catalogue of multimedia contents that is available on a remote data server; a second reception of a set of multimedia contents of the catalogue by at least one piece of user equipment; filtering the contents by the piece of user equipment broadcast by the satellite depending on the user filter; storing the received and filtered contents in a memory of the piece of user equipment.
