Network Receiver for IBOC DAB Signal Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current IBOC DAB radio broadcasting systems do not efficiently distribute program material and information to multiple users across a local area network, and users with different devices cannot access different programs or data streams within a single channel.
Innovation Solution
A network receiver and player system that converts over-the-air IBOC DAB signals to baseband signals, processes them according to a protocol stack, and delivers content to network player devices via a network access protocol, allowing multiple users to access different programs and data streams using various devices.

Engineering Contradiction Analysis
1Quantity of substance
If IBOC DAB signals are transmitted within the spectral mask of existing AM or FM channels, then spectrum efficiency is improved and no new spectral allocations are required, but the ability to distribute content to multiple users with different devices is limited
Solution Approach 1:
The patent segments the broadcast content into multiple program components and data streams that can be independently distributed to different network players. Each player can receive and process specific segments according to its capabilities, enabling versatile content distribution while maintaining efficient spectrum usage through the IBOC DAB transmission format.
Solution Approach 2:
The network receiver is designed with multi-functionality to handle various broadcast formats and distribute content to multiple types of network players (computers, televisions, portable devices). This universal approach enables the system to adapt to different devices and user needs while maintaining efficient spectrum utilization.
2Adaptability or versatility
If a single IBOC DAB channel transmits multiple program components and data streams, then content versatility is improved, but the complexity of distributing different content to different users increases
Solution Approach 1:
The network receiver serves as an intermediary device that receives the multiplexed IBOC DAB signal, separates the different program components and data streams, and distributes them to appropriate network players. This intermediary approach simplifies the overall system complexity by centralizing the demultiplexing and distribution functions in a single device.
Solution Approach 2:
The system segments the complex broadcast signal into distinct program components and data streams that can be independently routed to different network players. This segmentation reduces distribution complexity by allowing each player to receive only the content it needs, rather than requiring every player to process the entire multiplexed signal.
3Adaptability or versatility
If network players have different receiving capabilities, then device compatibility is improved, but the difficulty of ensuring proper content delivery increases
Solution Approach 1:
The system implements feedback mechanisms where network players communicate their receiving capabilities and content reception status to the network receiver. This feedback allows the receiver to adapt its distribution strategy to match player capabilities and verify proper content delivery, reducing the difficulty of detecting and measuring content delivery success across diverse devices.
