Wireless Screen Sharing for In-Flight Entertainment Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current in-flight entertainment systems face challenges in seamlessly sharing multimedia content from passengers' personal electronic devices across various video codecs and file formats, and in providing a convenient way for multiple passengers to view the same content without the need for holding small devices at awkward angles.
Innovation Solution
A wireless screen sharing system that allows passengers to pair their personal electronic devices with in-flight entertainment system display monitors, enabling the transmission of display data streams over a wireless link, and includes a media player application to handle encryption and licensing for secure content playback, allowing content to be rendered on multiple display monitors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If passengers use their personal electronic devices to view multimedia content, then content format compatibility is improved, but display area is reduced
Solution Approach 1:
The patent captures the display output from the personal electronic device and transmits it to the aircraft entertainment system display. This creates a copy of the content on a larger screen, allowing passengers to view their personal media on the aircraft's display system while maintaining format compatibility through the capture and retransmission process.
2Adaptability or versatility
If multiple passengers want to view the same content, then content sharing capability is improved, but device handling complexity increases
Solution Approach 1:
The patent allows the captured display stream to be distributed to multiple display locations within the aircraft entertainment system. The content sharing feature segments the single source stream into multiple output channels, enabling multiple passengers to view the same content on different screens without each passenger needing to physically share the device.
3Adaptability or versatility
If the system supports various video codecs and file formats, then format compatibility is improved, but system complexity increases
Solution Approach 1:
The patent employs an intermediary capture mechanism that intercepts the display output stream from the personal electronic device. This intermediary approach allows the system to receive content in various formats without requiring native support for each format, as the capture process handles the format conversion and transmission to the aircraft's display system.
Data Source
AI summary
An entertainment system for a vehicle accommodating a passenger with a personal electronic device executing a screen sharing application. The entertainment system includes a network onboard the vehicle and information processing devices connected to the network. Each device includes a data processor, and at least one including a display monitor and a screen sharing server executed by the data processor of the device with the screen sharing server being receptive to a display data stream communicated over the network to the screen sharing server by execution of the screen sharing application of the portable electronic device. The display data stream is communicated after pairing of the screen sharing application the device. A media player application executed by the data processor of the device determines if the display data stream is encrypted. If so, the media player application requests a license and after receipt of the license, a decrypted display data stream is rendered the display monitor.
