Interactive Video Playback in Electronic Maps for Road Events
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic maps lack intuitive and timely methods to provide road-related information, such as congestion, accidents, and construction, which limits the acquisition of valuable travel information.
Innovation Solution
A video playing method and apparatus that allows electronic maps to display timely and accurate road-related information through interactive video windows, triggered by user inputs on event controls within the map interface, enabling the acquisition of target video data and its playback within the map display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If electronic maps use traditional text-based prompt information for road events, then the system complexity is low, but the information intuitiveness and timeliness are insufficient
Solution Approach 1:
The patent uses video copies (video clips or live stream snapshots) to represent road events instead of traditional text icons. When users interact with event markers on the map, the system retrieves and displays video data from the server that visually captures the actual road conditions, accidents, or construction scenes, providing intuitive visual information about event severity and context.
Solution Approach 2:
The patent transitions from two-dimensional static map icons to three-dimensional video content integration. Video windows are overlaid on the map interface, creating a multi-dimensional information presentation that combines spatial map data with temporal video data, allowing users to view events from multiple perspectives and time points.
2Loss of information
If electronic maps display detailed video information for all road events, then the information completeness is improved, but the network bandwidth consumption and loading time increase
Solution Approach 1:
The patent implements differential video loading based on user interaction. Instead of pre-loading all video data, the system loads video content selectively when users interact with specific event markers. Different video qualities and types (clip vs. live stream) are provided based on the specific event and user needs, optimizing network bandwidth usage while maintaining information completeness on demand.
Solution Approach 2:
The patent performs preliminary verification of video data before full loading. The server first returns verification information about available video content, and only after successful verification does the terminal device proceed to download and play the actual video data. This preliminary action prevents wasted network bandwidth on unavailable or inappropriate video content.
3Reliability
If electronic maps implement video verification mechanism, then the data security and accuracy are improved, but the interaction steps and time increase
Solution Approach 1:
The patent performs video data verification in advance on the server side before returning data to the terminal. The server verifies whether the requested video data exists and is valid, then returns verification information along with the video data. This preliminary verification ensures data accuracy while minimizing the impact on user interaction time, as the verification occurs during the data retrieval process rather than as a separate user action.
4Adaptability or versatility
If electronic maps provide multiple video playback options (auto-play, manual play, network-adaptive play), then the user experience and adaptability are improved, but the control logic complexity increases
Solution Approach 1:
The patent implements dynamic video playback control that automatically adapts to network conditions and user preferences. The system monitors network bandwidth and device state in real-time, dynamically switching between auto-play mode (when network conditions are good), manual play mode (when users prefer control), and network-adaptive mode (when bandwidth is limited). This dynamic adjustment provides versatility while keeping control logic manageable through automated decision-making based on predefined conditions.
Data Source
AI summary
A video playing method includes: transmitting, in response to detecting a user input on a target control in a map display interface, a first acquisition request, the first acquisition request being used for acquiring target video data corresponding to the target control; receiving response information for the first acquisition request, and acquiring the target video data based on the response information; and displaying a video window on the map display interface, the video window being used for playing the target video data.
