Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing media source and playing equipment are independently controlled, leading to complex and inconvenient user operations due to separate controllers and lack of integrated control methods.
Innovation Solution
A control method that allows media playing equipment to receive and transform user operation instructions into processing instructions for media source equipment, using HDMI interfaces for communication, enabling unified control through a single interface for both display and source devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If media source equipment and media playing equipment are controlled independently by separate controllers, then each equipment can be controlled precisely, but the control complexity increases and user convenience decreases
Solution Approach 1:
The patent merges the control functions of media source equipment and media playing equipment into a unified control system. The media playing equipment's controller is enhanced to send control instructions to the media source equipment, eliminating the need for separate controllers and reducing overall system complexity while improving user convenience.
Solution Approach 2:
The controller of the media playing equipment is designed with multi-functional capabilities, enabling it to control both the media playing equipment itself and the media source equipment. This universal control approach allows a single controller to perform multiple functions, reducing the number of separate control devices needed.
2Ease of operation
If separate controllers are used for media source equipment and media playing equipment, then each controller can be optimized for its specific device, but user convenience decreases due to multiple controllers
Solution Approach 1:
The media playing equipment's controller is designed to universally control both itself and the media source equipment. This multi-functional controller maintains adaptability through standardized communication interfaces while reducing the number of separate controllers from two to one, thereby improving user convenience.
Solution Approach 2:
The patent introduces an intermediary control mechanism where the media playing equipment's controller acts as a mediator between the user and both devices. This intermediary approach allows unified control while maintaining the specialized functions of each device through standardized communication protocols.
3Device complexity
If independent control systems are used for media source and playing equipment, then each system can operate autonomously, but the overall system complexity increases
Solution Approach 1:
The patent segments the control functions into two levels: the media source equipment maintains autonomous operation capabilities for its core functions, while the media playing equipment's controller handles integrated control. This segmentation allows each component to operate autonomously when needed while enabling coordinated control when required, reducing overall system complexity.
Solution Approach 2:
The control system is designed dynamically, allowing the media playing equipment's controller to adaptively switch between controlling only itself and controlling both itself and the media source equipment. This dynamic control approach maintains reliability through autonomous operation capabilities while reducing complexity through integrated control when needed.
Data Source
AI summary
A control method for media playing, including: receiving user operation instructions by a media playing equipment; and transforming the user operation instructions into processing instructions corresponding to a media source equipment and forwarding the processing instructions to the media source equipment, if the menu currently displayed by the media playing equipment is not the control menu of the media playing equipment and the information input channel of the media playing equipment is the channel for the media source equipment inputting information to the media playing equipment. The method reduce the complexity of the user operation. A media source equipment, a media playing equipment and a system are also provided.
