Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If audio is constantly output from multiple wireless communication circuits to audio output devices, then audio coverage is improved, but power consumption increases
Solution Approach 1:
The patent merges multiple wireless communication circuits into a single active circuit for audio output when the same audio is being transmitted to multiple devices. The control circuit detects when identical audio signals are present across multiple output circuits and consolidates the transmission to one circuit, thereby maintaining audio coverage while eliminating redundant power consumption from parallel transmissions.
Solution Approach 2:
The system dynamically adjusts the operating state of wireless communication circuits based on real-time detection of audio signal identity. The control circuit continuously monitors whether multiple audio signals are identical and switches circuits between active and power-saving modes accordingly, creating a dynamic power management system that adapts to current playback conditions.
2Reliability
If multiple wireless communication circuits operate simultaneously, then audio output reliability is improved, but power consumption increases
Solution Approach 1:
The patent merges multiple wireless communication circuits into a single active circuit for audio output when the same audio is being transmitted to multiple devices. The control circuit detects when identical audio signals are present across multiple output circuits and consolidates the transmission to one circuit, thereby maintaining audio coverage while eliminating redundant power consumption from parallel transmissions.
Solution Approach 2:
The control circuit implements a feedback mechanism that continuously monitors the audio signals from multiple wireless communication circuits, compares their identity, and adjusts the operating state of each circuit based on this feedback. When signals are identical, the system feedback-induces a power-saving state for redundant circuits while maintaining reliable audio output through the active circuit.

AI summary
An information processing device includes first and second output circuits and a control circuit. The first output circuit outputs a first video included in a first video/audio to a first display region, and outputs a first audio included in the first video/audio to a first wireless communication circuit that outputs an audio to a first audio output device by wireless communication. The second output circuit outputs a second video included in a second video/audio to a second display region, and outputs a second audio included in the second video/audio to a second wireless communication circuit that outputs an audio to a second audio output device by wireless communication. When it is determined that the first video/audio and the second video/audio are the same video/audio, the control circuit operates the second wireless communication circuit in the power saving mode.
