Terminal Content Reproduction via Metadata-Driven External Device Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current content reproduction systems lack the ability to seamlessly integrate with various external devices for dynamic and flexible content playback, limiting user experience and functionality.
Innovation Solution
A method and terminal system that obtain metadata for a predetermined content portion, select and control external devices via a control command, allowing for interoperation to reproduce the content, including executing applications for content playback and device control, and utilizing protocols like Wi-Fi Direct, Bluetooth, and ZigBee for communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If content is reproduced using only the terminal device, then the system is simple and easy to control, but the adaptability and versatility of content playback are limited
Solution Approach 1:
The terminal device is designed to perform multiple functions: it can reproduce content locally, select and control external devices, and manage metadata. This multi-functionality allows the system to adapt to different playback scenarios without requiring separate dedicated devices for each function, thereby improving adaptability while controlling complexity.
Solution Approach 2:
Metadata acts as an intermediary element that bridges the terminal device and external devices. The metadata contains information about content portions and associated external devices, enabling the terminal to selectively control external devices without requiring complex direct communication protocols between all possible device pairs, thus improving adaptability while managing system complexity.
2Adaptability or versatility
If multiple external devices are integrated for content reproduction, then the functionality and user experience are enhanced, but the device complexity and control difficulty increase
Solution Approach 1:
The content is divided into different portions, each associated with specific metadata that identifies suitable external devices. This segmentation allows the terminal to control only the relevant external devices for each content portion rather than managing all connected devices simultaneously, enhancing functionality while reducing control difficulty through selective device engagement.
Solution Approach 2:
Metadata is prepared in advance, containing information about content portions and their associated external devices. This preliminary organization of device information allows the terminal to quickly select and control appropriate external devices when content playback is requested, enhancing system functionality while simplifying the control process by eliminating the need for real-time device discovery and compatibility checking.
3Measurement precision
If external devices are selected based on comprehensive metadata analysis, then the precision of device selection is improved, but the processing time and system complexity increase
Solution Approach 1:
The terminal device performs partial metadata analysis by focusing only on the specific metadata elements relevant to the current content portion being reproduced, rather than analyzing all available metadata comprehensively. This selective approach maintains selection precision for the current task while reducing processing time by avoiding unnecessary analysis of unrelated metadata.
Solution Approach 2:
Metadata is organized and prepared in advance with pre-identified associations between content portions and external devices. This preliminary structuring allows the terminal to perform rapid lookups based on content identifiers rather than conducting comprehensive analysis during playback, thereby maintaining high selection precision while significantly reducing processing time during actual content reproduction.

AI summary
A method of reproducing content is provided. The method performed by a terminal includes operations of obtaining metadata corresponding to a predetermined portion of the content, selecting, based on the metadata, at least one external device to reproduce the predetermined portion of the content, transmitting a control command to the at least one external device, and reproducing the predetermined portion of the content by interoperation of the terminal with the at least one external device to which the control command is transmitted.
