Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio and video codec systems consume unnecessary power and resources when not required for output processing, as they lack programmable analog input/output pins and require manual user inputs to disable functions, leading to a tradeoff between usability and performance.
Innovation Solution
A system and method that automatically disable input/output signal processing based on the required multimedia format by using a programmable I/O IC system with a control module that senses external device impedance and generates control signals to configure I/O modules, enabling or disabling them as needed, thereby conserving power and resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the codec operates with all processing modules enabled, then signal processing capability is maintained, but power consumption increases
Solution Approach 1:
The patent implements dynamic configuration of I/O modules where the system automatically enables or disables analog input/output pins and associated processing modules based on real-time detection of external device impedance. This dynamic adaptation allows the codec to maintain signal processing capability only when external devices are connected, thereby reducing power consumption during idle periods while ensuring reliability when devices are present.
Solution Approach 2:
The system employs automatic detection and configuration mechanisms that eliminate the need for manual user input to enable or disable processing modules. The codec autonomously monitors impedance at I/O pins, determines device presence, and self-adjusts the operational state of processing modules accordingly, achieving both power efficiency and maintained capability without user intervention.
2Use of energy by moving object
If manual user input is required to disable functions, then power consumption is reduced, but ease of operation deteriorates
Solution Approach 1:
The patent implements automatic detection and configuration mechanisms that eliminate the need for manual user input to enable or disable processing modules. The codec autonomously monitors impedance at I/O pins, determines device presence, and self-adjusts the operational state of processing modules accordingly, achieving both power efficiency and maintained capability without user intervention.
Solution Approach 2:
The system continuously monitors impedance at I/O pins and uses this feedback information to automatically adjust the operational state of processing modules. This closed-loop feedback mechanism ensures that the system responds automatically to device presence or absence, maintaining ease of operation while optimizing power consumption based on actual usage conditions.

Data Source
AI summary
A system and method operable to automatically disable input/output signal processing based on the required data format is provided. The need for an input/output module, such as an encoder, required to process input signal having a first data format (i.e. multimedia format) and produce an output signal having a second format (i.e. multimedia format) is determined. When the input/output module is not required to produce the output signal in the second format, the input/output module is disabled.
