Asymmetric Broadcast Content Customization via Metadata Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing asymmetric communication systems, such as satellite and cable broadcasting, lack efficient methods for content customization due to their unidirectional nature and large number of receivers, making it difficult to provide personalized content effectively.
Innovation Solution
The system transmits excess information that includes both primary and auxiliary data, where auxiliary data is customizable based on user-specific factors like location, subscription status, and demographics, using metadata to determine which sections of the transmission are customized and presented to users, allowing for real-time adjustments and varied content delivery across multiple channels.

Engineering Contradiction Analysis
1Loss of energy
If asymmetric communication is used for broadcasting to many receivers, then bandwidth usage is improved and transmitter receiving capability requirements are reduced, but content customization capability deteriorates
Solution Approach 1:
The broadcast content is segmented into multiple versions or variants (e.g., different language tracks, subtitle options, audio descriptions). The transmitter sends the primary content once, and receivers selectively assemble customized versions by choosing from the provided segments based on user preferences, thereby achieving customization without requiring multiple full transmissions.
Solution Approach 2:
The transmitter preliminarily prepares multiple content variants and embeds selection metadata within the broadcast signal. Receivers perform the customization action locally by selecting from pre-prepared variants based on user profile data, eliminating the need for real-time feedback and post-transmission customization.
2Adaptability or versatility
If excess information is transmitted to enable customization, then content customization capability is improved, but bandwidth usage deteriorates
Solution Approach 1:
Instead of transmitting complete alternative content versions, the system transmits only the差异化 portions (local differences) between variants. For example, if two audio tracks differ by only 10% of their content, only those 10% differences are transmitted as supplemental data, and the receiver synthesizes the full variant locally, thereby minimizing bandwidth consumption while enabling full customization.
Solution Approach 2:
The receiver creates local copies or reconstructions of full content variants by combining the primary broadcast content with received customization data. This allows the system to transmit minimal supplemental information while the receiver generates complete customized versions, avoiding the need to transmit multiple full copies of content.
3Manufacturing precision
If real-time feedback is implemented for customization, then content customization precision is improved, but communication symmetry requirement increases
Solution Approach 1:
The system introduces an intermediary layer of pre-configured content variants and selection metadata that mediates between the transmitter and receiver. This intermediary structure allows the receiver to perform high-precision customization locally by selecting from predefined variants, eliminating the need for complex real-time feedback loops and maintaining asymmetric communication architecture.

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.
