Control Apparatus for Precise Video Playback Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control systems for video content playback over communications networks, such as those conforming to DLNA guidelines, lack efficiency in controlling playback positions, particularly in skipping commercial messages, due to limitations in processing capacity and user interaction.
Innovation Solution
A control apparatus connected to a server device and a playback device, equipped with a receiver and controller, analyzes video content to determine a first playback position and transmits this information to the playback device, allowing for precise control of playback positions, even with low-processing-capacity devices like television receivers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the playback device determines playback positions based on content analysis, then playback control precision is improved, but device complexity and processing capacity requirements increase
Solution Approach 1:
A control device is introduced as an intermediary between the content source and the playback device. The control device performs content analysis to determine playback positions (such as chapter markers, scene transitions, or commercial message boundaries) and transmits this information to the playback device. This allows the playback device to execute precise playback control without having to perform complex content analysis itself, thus resolving the contradiction between precision and device complexity.
2Measurement precision
If the playback device analyzes video content to detect playback positions, then playback position accuracy is improved, but processing capacity requirements increase
Solution Approach 1:
The control device serves as an intermediary that performs the computationally intensive content analysis function. It analyzes the video content to detect meaningful playback positions and transmits only the essential position information to the playback device. This approach maintains high playback position accuracy while significantly reducing the processing capacity requirements of the playback device, as it only needs to receive and execute position commands rather than perform complex analysis.
3Ease of operation
If manual user interaction is required to control playback positions, then system complexity is reduced, but ease of operation and user convenience deteriorate
Solution Approach 1:
The system implements automatic playback position control by having the control device analyze content and automatically determine appropriate playback positions without requiring manual user input. The control device can identify chapter markers, scene transitions, or commercial message boundaries and automatically adjust playback positions based on user preferences or predefined rules. This self-service approach dramatically improves ease of operation, allowing users to simply press play while the system handles the complex position control automatically.
Data Source
AI summary
A control apparatus is connected to a server device storing content and to a playback device, and controls playback of the content at the playback device. The control apparatus includes a receiver that receives the content from the server device, and a controller that transmits to the playback device information about a first playback position in the content received by the receiver.
