Vehicle Broadcast Handling for Targeted ATSC Navigation Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Connected vehicles incur high data costs when data is sent individually to a large number of vehicles, and existing one-to-many broadcast technologies like ATSC 3.0 do not allow for targeted data delivery to specific vehicles.
Innovation Solution
A system that uses a server to prepare and send targeted data via ATSC television stations, allowing vehicles to receive relevant data through broadcasts, with parameters determining applicability based on vehicle characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If data is sent individually to each vehicle via direct connection, then targeted delivery to specific vehicles is achieved, but data communication costs increase significantly
Solution Approach 1:
The system segments vehicles into different groups based on their characteristics (location, vehicle type, software version) and delivers targeted data to each segment through selective ATSC broadcast reception, achieving cost reduction while maintaining targeted delivery capability
Solution Approach 2:
The patent introduces ATSC broadcast stations as intermediaries between the data source and vehicles. The server sends data to broadcast stations, which then distribute it to vehicles in their coverage area, enabling efficient one-to-many communication with targeted delivery
2Loss of information
If ATSC broadcast is used for one-to-many data delivery, then data communication costs are reduced, but the ability to target data to specific vehicles is lost
Solution Approach 1:
The system applies local quality by tailoring broadcast content to specific local areas and vehicle groups. Different data is broadcast to different geographic regions and to different vehicle types within the same region, enabling precise targeting while using efficient broadcast infrastructure
Solution Approach 2:
The patent implements dynamic data selection where the server determines which data to broadcast based on real-time vehicle characteristics, location information, and broadcast station coverage areas. This dynamic approach allows the system to adapt broadcast content to specific vehicle needs while using the efficient ATSC broadcast infrastructure
3Productivity
If broadcast data is sent to all vehicles in coverage area, then simultaneous data delivery to multiple vehicles is achieved, but unnecessary data processing occurs for vehicles not needing the data
Solution Approach 1:
The server performs preliminary action by pre-determining which vehicles should receive specific data based on their characteristics and location before the broadcast occurs. This allows the system to prepare targeted broadcast content in advance, reducing unnecessary processing for vehicles that don't need the data
Solution Approach 2:
The system uses feedback mechanisms where vehicles report their characteristics and location information to the server, which then uses this feedback to determine the appropriate broadcast content. This feedback loop ensures that only necessary data is broadcast and processed, reducing energy consumption while maintaining fast delivery
Data Source
AI summary
A system wirelessly receives identification of a reportable navigation event from one or more vehicles, the identification including vehicle location information. The system determines a locality to which the reportable event applies. The system determines one or more television broadcast stations predefined as having a broadcast area that covers the locality. Additionally, the system defines navigation data for vehicle navigation systems to address the event and deliver the navigation data to the determined television stations, along with broadcast instructions for the television stations to broadcast the navigation data via Advanced Television System Committee (ATSC) technology.
