Remote Control System for Smart TV Playback Task Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart televisions present complex interactions for un-savvy users, making it difficult for them to navigate and utilize Internet features such as searching, selecting, and playing video content.
Innovation Solution
A remote control method that allows users to customize video playback tasks, including content file sources and playback times, by generating and communicating instructions to the playback device, which can switch from standby mode to power-on mode and retrieve content files from designated sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If smart television provides many Internet features and additional functions, then the functionality and versatility of the device is improved, but the complexity of operation and user interface increases making it difficult for un-savvy users
Solution Approach 1:
A remote control device serves as an intermediary between the user and the smart television system. The remote control provides a simplified interface that mediates complex operations, allowing users to control video playback and access content without needing to navigate the complex smart television interface directly. The remote control translates simple user actions into the appropriate commands for the sophisticated playback system.
Solution Approach 2:
The system separates the complexity of Internet feature management from the user interaction layer. The smart television handles complex functions (content retrieval, playback control, Internet connectivity) while the remote control provides a segmented, simplified interface for basic operations. This segmentation allows each component to specialize - the television handles versatility while the remote handles ease of operation.
2Ease of operation
If the remote control device stores and processes playback tasks and instructions locally, then the ease of operation is improved, but the processing power and memory requirements of the remote control increase
Solution Approach 1:
The patent extracts the heavy processing and storage requirements from the remote control device and relocates them to the smart television or server system. The remote control only stores minimal task identification information and transmits simple control instructions, while the actual playback task management, content retrieval, and instruction generation are performed by the more powerful television system with adequate memory resources.
Solution Approach 2:
The remote control acts as a lightweight intermediary that initiates tasks and transmits minimal instructions, while the smart television serves as the intermediary between the remote control and the content source. The television handles the memory-intensive operations of storing playback tasks, managing content files, and generating detailed playback instructions, thereby protecting the remote control from memory constraints.
3Use of energy by moving object
If the playback device remains in standby mode to conserve energy, then energy consumption is reduced, but the device cannot immediately execute playback tasks when instructed
Solution Approach 1:
The system performs preliminary actions by pre-configuring playback tasks with all necessary information (content source, timing, instructions) while the device is in standby mode. When execution is requested, the pre-prepared instructions are immediately transmitted to the playback device, which can then activate and execute the task without delay. The playback device enters standby with minimal processing needed, yet can rapidly transition to execution mode because all decision-making and instruction generation were completed in advance.
Data Source
AI summary
A remote control system for a video playback device, such as a smart television is provided herein. The system can obtain a playback task customized by a user via a server or a remote control device. The playback task can include at least a content file source. The server or remote control device can obtain playback instructions corresponding to the playback task and communicate the playback instructions to the playback device. The playback device can obtain a content file from the content file source via a residential gateway associated with the playback task after receiving the playback instructions, and then play the content file.
