Multimedia Broadcast Preloading for Peak-Time Network Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High bit rate broadcast networks experience uneven load distribution, leading to network saturation during busy times and underutilization during slack times, resulting in poor user experience and significant loss of potential profit for operators.
Innovation Solution
A method of broadcasting multimedia information items that involves determining user interest through predefined classification and descriptors, allowing for pre-broadcasting of relevant items during slack times and local storage in receivers, reducing redundant data transmission and optimizing network usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high capacity network infrastructure is installed to enhance daytime service quality, then service quality during daytime is improved, but network utilization during slack times deteriorates (significant underuse and loss of potential profit)
Solution Approach 1:
The system performs preliminary actions by broadcasting information item descriptors during slack times (night hours) when network load is low. Receivers pre-qualify and store information items locally based on user profiles before peak demand occurs. This advance preparation ensures rapid access during daytime without requiring increased network capacity, thereby maintaining high service quality while optimizing network utilization across different time periods.
2Speed
If information items are broadcast during daytime to meet user demand, then user access speed is improved, but network load increases (contributing to saturation and longer response times)
Solution Approach 1:
The system broadcasts descriptors and pre-loads information items during off-peak nighttime hours when network capacity is underutilized. This preliminary action transfers data before demand peaks, enabling receivers to access stored information locally during daytime without contributing to network saturation. The approach maintains fast user access while preserving network productivity during peak periods.
Solution Approach 2:
The system creates local copies of information items in receiver devices based on user-specific profiles. Instead of repeatedly transmitting the same information over the network to multiple users during peak times, each receiver stores relevant information locally. This copying mechanism eliminates redundant network transmissions, reduces load on saturated networks, and enables immediate local access for multiple users simultaneously.
3Adaptability or versatility
If the same information is transmitted multiple times to different users during daytime, then user-specific information delivery is achieved, but network saturation occurs (limiting bit rate and increasing response times)
Solution Approach 1:
The system generates user-specific copies of information items by filtering broadcast content through individual user profiles stored in each receiver. During slack times, receivers qualify information items against their specific user profiles and store only relevant items locally. During daytime, users access their personalized information collections without requiring repeated network transmissions. This copying approach delivers tailored information to each user while eliminating redundant network traffic that causes saturation.
Solution Approach 2:
The system performs preliminary user-specific filtering and selection of information items during nighttime when network load is low. Each receiver pre-qualifies broadcast descriptors against its stored user profile and pre-loads relevant information items locally. This advance user-specific preparation ensures that during daytime peak periods, each user can immediately access their personalized information without requiring real-time network queries, thereby maintaining adaptability while preserving network productivity.

AI summary
A method of broadcasting multimedia information items, a receiver of multimedia information items broadcast by that method, and a user interface for consulting the information items. The invention relates to a method of broadcasting multimedia information items in a network comprising a transmitter and at least one receiver of information, the method including determining a class to which each information item belongs, broadcasting ahead of time a descriptor relating to each information item, at each receiver, qualifying the potential interest of each information item on the basis of the descriptors received and as a function of a user profile defined in the receiver, broadcasting the information items associated with the descriptors previously broadcast, and, in each receiver, storing locally each information item as a function of the qualification based on the descriptors. The invention also relates to a receiver and a user interface for consulting broadcast information items.
