Vehicle Base Media Architecture Using External AR Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle media systems often lack sufficient hardware capabilities to enable advanced augmented-reality media processing effects, such as immersive audio and video, due to cost constraints, limiting user experience.
Innovation Solution
A base media system (BMS) in vehicles is complemented by an external media system (EMS), which can provide additional processing power through wireless or wired communication, allowing the BMS to access advanced signal processing features via cloud-computing devices or separate devices, overcoming hardware limitations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If advanced augmented-reality media processing effects are implemented in vehicle media systems, then user experience is improved, but hardware cost and complexity increase
Solution Approach 1:
The patent introduces an external media system (EMS) as an intermediary component that provides advanced media processing capabilities externally. The EMS processes media content and transmits the processed output to the base media system (BMS) for playback, allowing the vehicle to access augmented-reality effects without embedding complex processing hardware directly in the vehicle's BMS.
Solution Approach 2:
The patent moves the advanced processing functionality from the traditional in-vehicle dimension to an external dimension via the EMS. This can be implemented as a cloud-based service, a portable external device, or a separately installed system, effectively adding a new spatial and architectural dimension to the media processing architecture.
2Adaptability or versatility
If advanced augmented-reality media processing effects are implemented in vehicle media systems, then user experience is improved, but manufacturing cost increases
Solution Approach 1:
By introducing the EMS as an external intermediary, the patent allows manufacturers to produce vehicles with standard BMS at lower cost points. Advanced processing capabilities are provided on-demand through the EMS, which can be a cloud service (no additional hardware cost) or an optional external accessory, rather than requiring all vehicles to be equipped with expensive integrated processing hardware.
Solution Approach 2:
The EMS serves multiple functions: it provides advanced augmented-reality processing when needed, while allowing the BMS to operate independently with basic capabilities. This multi-functionality allows a single architecture to serve both cost-sensitive base models and premium configurations, reducing overall manufacturing complexity and cost.
3Manufacturing precision
If advanced augmented-reality media processing effects are implemented in vehicle media systems, then media processing quality is improved, but system complexity increases
Solution Approach 1:
The EMS acts as a specialized intermediary that handles all complex augmented-reality processing tasks externally. The BMS maintains its simple, well-defined role of receiving processed output and driving speakers/displays. This clear separation of concerns reduces system complexity by eliminating the need for the BMS to contain complex processing logic while still achieving high processing quality through the EMS.

AI summary
Methods and systems are provided for enabling vehicular media systems incorporating a base media system (BMS) and an external media system (EMS). Methods may establish electronic communication links between a BMS installed in a vehicle and an EMS carried by the vehicle. A communication between the BMS and the EMS may identify one or more media channels for which the BMS is to receive streaming content from the EMS. The BMS may process a first media stream based on one or more media sources to create a first stream of content for the one or more media channels, and may receive from the EMS (over the point-to-point electronic communication link) a second stream of content for the one or more media channels. The BMS may select between providing the first stream of content or the second stream of content to an output interface coupled to one or more media sinks.
