Tiered Subscription Broadcast System Using Receiver Memory
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current broadcast systems face challenges in offering tiered subscription services without halving the number of channels, as they need to transmit both commercial and commercial-free versions of each channel, leading to inefficient bandwidth usage and limited flexibility in advertising targeting.
Innovation Solution
The system uses memory at the receiver to store commercials and transmits commands to the receiver to insert or delete content segments, allowing for multiple tiers of service over a single channel, with commercials being stored and transmitted separately on an auxiliary channel, enabling targeted advertising and secure access control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two versions of each channel are broadcast (with commercials and without), then tiered subscription service is provided, but the number of available channels is halved
Solution Approach 1:
The broadcast signal is segmented into base content and commercial content streams. The base content is transmitted once, while commercials are transmitted separately and selectively inserted at the receiver based on subscriber tier, eliminating the need to broadcast duplicate channels.
Solution Approach 2:
The receiver acts as an intermediary that receives base content and selectively inserts commercial content based on subscriber tier. This intermediary function allows a single broadcast to serve multiple subscriber types without requiring separate broadcast channels for each tier.
2Adaptability or versatility
If two versions of each channel are broadcast (with commercials and without), then tiered subscription service is provided, but bandwidth requirements increase
Solution Approach 1:
The broadcast is divided into essential content (base layer) and optional content (commercial layer). By segmenting the content stream, the system transmits base content once efficiently, then adds commercial content only when needed, reducing overall bandwidth consumption compared to transmitting complete duplicate channels.
Solution Approach 2:
Instead of transmitting complete commercial-free versions of all channels for every subscriber, the system transmits base content partially (without commercials) and adds commercials only to lower-tier subscriptions, avoiding excessive bandwidth usage by providing only necessary content to each subscriber group.
3Object-generated harmful factors
If commercials are inserted into content streams, then advertising revenue is generated, but content quality and listening experience deteriorate
Solution Approach 1:
Different quality levels are provided locally to different subscriber groups. Premium subscribers receive high-quality commercial-free content, while standard subscribers receive content with commercials. This local differentiation allows the system to maintain content quality for paying subscribers while generating advertising revenue from standard subscribers.
Solution Approach 2:
Instead of modifying the original content stream, the system creates a copy of the base content and selectively inserts commercials into copies for lower-tier subscribers. This copying approach preserves the original high-quality content integrity for premium subscribers while allowing commercial insertion for standard subscribers.

AI summary
A broadcast system is disclosed that allows a broadcaster to provide multiple levels of subscription services. Subscribers have the option of listening to fewer (or no) commercials if they pay a higher fee, or listening to more commercials if they pay a lower (or no) fee. Commercials can be demographically targeted, cannot be skipped, and can be audited for billing purposes.
