Wireless Content Reproduction Apparatus Audio Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing car-mounted content reproduction systems lack the ability to easily switch between shared and non-shared states for video content, leading to cumbersome installations and user inconvenience, as they require cable connections and do not allow for seamless control of audio output based on sharing states.
Innovation Solution
A content reproduction apparatus and system that includes a reproduction block, a display block, a communication block, a speaker block, and an audio output control block, enabling wireless communication and automatic audio control between a vehicle-mounted unit and a portable terminal, allowing users to switch between shared and non-shared states without cable connections, thereby controlling audio output accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cable connection is used to connect rear monitor and content reproduction apparatus, then video content can be displayed on rear monitor, but installation work becomes cumbersome due to installation restrictions
Solution Approach 1:
The patent replaces the mechanical cable connection system with a wireless communication system. The content reproduction apparatus transmits video content wirelessly to the rear monitor via a wireless communication unit, eliminating the need for physical cable connections and simplifying installation while maintaining video display functionality.
2Ease of operation
If video content is shared with other users, then user convenience is enhanced, but audio content from second speakers may cause disturbance to users playing games or using applications
Solution Approach 1:
The patent implements dynamic audio output control based on the sharing state. The audio output control unit dynamically adjusts audio reproduction by first speaker and second speaker according to whether the portable terminal is in content share state or not, allowing the system to adapt audio behavior to user needs and prevent disturbance.
Solution Approach 2:
The patent applies different audio reproduction characteristics to different speakers based on local requirements. When in non-share state, the second speaker stops reproducing audio content to avoid disturbance to users engaged in games or applications, while the first speaker maintains audio reproduction for the driver.
3Reliability
If automatic audio control is implemented based on share states, then undesired audio reproduction is prevented, but system complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the audio output control unit receives information about the sharing state from the communication unit and adjusts audio reproduction accordingly. This feedback-based control ensures accurate audio output management based on real-time system state without requiring complex manual intervention.

AI summary
Disclosed herein is a content reproduction apparatus including: a reproduction block configured to reproduce video content; a display block configured to display the reproduced video content; a communication block configured to transmit the video content to a portable reproduction apparatus by wireless communication; a speaker block having at least one first speaker located in proximity and at least one second speaker located in the proximity of the portable reproduction apparatus; and an audio output control block configured to control a reproduction state of the speaker block. In a state where the video content is displayed on the display block, each of the first speaker and the second speaker reproduces audio content related with the video content. In a content non-share state, the audio output control block controls audio output such that the second speaker does not reproduce audio content related with the video content.
