Vehicle Content Scheduling via Segmented Program Listings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional content-display scheduling systems for vehicles interrupt the display of high real-time sensitive content, such as news and weather forecasts, when scheduling low real-time sensitive content, like advertisements, leading to unsynchronized display orders.
Innovation Solution
A content-display scheduling system that includes separate editing and distribution mechanisms for high and low real-time sensitive content, using external and advertisement program listings to manage display orders, allowing ground-side management of content scheduling for vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If content with high real-time sensitivity (news, weather forecasts) is displayed by interrupting content with low real-time sensitivity (advertisements) at the in-vehicle terminal, then the real-time sensitivity of news and weather forecasts is improved, but the display order cannot be scheduled on the ground side where content is managed
Solution Approach 1:
The patent segments the content display system into two distinct scheduling components: an external program listing for high real-time sensitivity content (news, weather forecasts) and an advertisement program listing for low real-time sensitivity content (advertisements). This segmentation allows independent scheduling of each content type while maintaining overall ground-side control. The external program listing operates independently to ensure real-time content is displayed promptly, while the advertisement program listing fills remaining time slots, resolving the contradiction between real-time responsiveness and centralized scheduling management.
2Ease of operation
If separate scheduling is implemented for high and low real-time sensitive content, then ground-side scheduling capability is improved, but the system complexity increases due to multiple program listings and distribution mechanisms
Solution Approach 1:
The patent merges the scheduling functions into a unified ground-side management system that handles both external program listings and advertisement program listings through the same distribution infrastructure. The content database consolidates all content types, and the distribution server manages both scheduling listings simultaneously. This merging approach reduces system complexity by using common components (distribution server, content database, distribution devices) for both high and low real-time sensitivity content, while still maintaining separate scheduling logic for each content type.
3Loss of information
If news and weather forecasts are updated frequently with high real-time sensitivity, then the real-time information quality is improved, but the display order becomes unsynchronized with advertisement content scheduled at lower updating frequency
Solution Approach 1:
The patent implements dynamic scheduling where the external program listing for high real-time sensitivity content can be updated independently and frequently, while the advertisement program listing maintains a more stable, pre-planned schedule. The system dynamically adjusts the advertisement display timing to accommodate real-time news and weather content, allowing the advertisement listing to adapt its execution based on when external program content is actually displayed. This dynamic approach preserves real-time information quality while maintaining overall display order synchronization through flexible timing adjustment.

AI summary
There are provided a news/weather-forecast editing device that updates content with a high real-time sensitivity and information that constitutes an external program listing; a news/weather-forecast dedicated distribution server that creates an external program listing showing a display order of the content with a high real-time sensitivity, an advertisement-content editing device that updates content with a low real-time sensitivity and an advertisement program listing, which shows a display order of the content with a low real-time sensitivity and also a display order that follows the external program listing; a content database that stores therein the content and the program listings; a distribution server that periodically checks the content database and distributes updated content and program listings; and individual distribution devices that distribute content and program listings that have been distributed from the distribution server to vehicles that display the content according to the display order.
