Asymmetric Broadcast Customization via Segmented Data Streams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing asymmetric communication systems, such as satellite and cable broadcasting, lack efficient methods for providing customization to multiple receivers due to their unidirectional nature, which limits feedback and customization options.
Innovation Solution
A system that transmits excess information, including primary and auxiliary data, where auxiliary data is selectively presented to users based on customization factors like location, subscription status, and demographics, using metadata to differentiate and assemble customized output streams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If asymmetric communication is used for broadcasting to many receivers, then bandwidth efficiency is improved and transmitter receiving capability is reduced, but content customization capability deteriorates
Solution Approach 1:
The broadcast signal is segmented into common data (transmitted once for all receivers) and selective data (transmitted only when needed). This segmentation allows the system to maintain bandwidth efficiency by transmitting common data once while enabling customization by selectively transmitting only the portions of auxiliary data that individual receivers need, based on their identification information and customization factors.
Solution Approach 2:
The system transmits identification information and customization factors to receivers in advance, allowing receivers to pre-determine which auxiliary data segments they need. This preliminary action enables efficient bandwidth usage by avoiding unnecessary data transmission while maintaining customization capability through pre-configured selection criteria at the receiver end.
2Device complexity
If unidirectional broadcast is used, then system complexity is reduced and feedback requirements are eliminated, but customization responsiveness deteriorates
Solution Approach 1:
Receivers perform self-selection of auxiliary data segments based on their stored identification information and received customization factors. This self-service mechanism eliminates the need for complex feedback loops while maintaining customization responsiveness, as each receiver autonomously determines which data segments to receive based on pre-established criteria without requiring transmitter feedback.
3Adaptability or versatility
If excess information is transmitted for customization, then customization capability is improved, but information redundancy increases
Solution Approach 1:
The system transmits auxiliary data in excess of what any single receiver immediately needs, allowing receivers to select only the portions they require based on customization factors. This partial excessive action enables future-proof customization where receivers can access previously transmitted auxiliary data segments that may become relevant later, while minimizing redundancy by allowing receivers to discard unneeded segments.
Solution Approach 2:
Auxiliary data is transmitted in advance with embedded identification information and customization factors, allowing receivers to pre-select and store only the segments they will need. This preliminary action reduces information redundancy by enabling receivers to discard unneeded data segments before they are actually required, while maintaining the capability for future customization.

AI summary
Systems and methods for providing customization in asymmetric communication are disclosed. An excess of information is broadcast from a transmitter to multiple receivers in what is optionally a one-way transmission. The excess of information includes metadata used to select which subset of the excess of information is presented to a user and which subset of the excess of information is discarded. The metadata includes criteria that are compared with various, possibly different, customization factors stored on each of the multiple receivers. This comparison is used to determine which subsets of the excess information are presented and which are discarded. Because the customization factors can be different on different receivers, customization of the presented information is achieved. The customization factors optionally include geographic information resulting in customization based on a receiver location. The excess information optionally includes radio or television signals. In some embodiments, a nationally broadcast signal results in the presentation of advertisements, where the presentation is customized to a specific location.
