Wireless Media Transfer Between Mobile and Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices struggle to effectively present and transfer media, such as images and videos, due to their small display size and limited resolution, and existing methods often result in time-consuming processes and media proliferation through intermediary sources.
Innovation Solution
A system and method for wirelessly receiving and transmitting media between multimode mobile communication devices and display devices, with the ability to selectively disable control by the display device over media presentation, using various communication modes such as cellular, WiMAX, and Bluetooth, to facilitate seamless media sharing and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If media is transferred via removable storage medium, then compatibility between devices is improved, but time consumption increases
Solution Approach 1:
The patent replaces the mechanical system of physical media transfer (removable storage devices) with a wireless electromagnetic communication system. The mobile communication device establishes wireless connections with both the source and display devices, transmitting media data through air interface protocols, thereby eliminating the need for physical insertion and extraction of storage media while maintaining broad device compatibility.
Solution Approach 2:
The mobile communication device serves as an intermediary between the source device and display device. It receives media from the source device wirelessly, stores it temporarily in its own memory, and then transmits it to the display device. This intermediary approach enables compatibility between devices that cannot directly communicate while significantly reducing transfer time compared to physical media methods.
2Adaptability or versatility
If media is transferred via intermediary source, then device compatibility is improved, but media proliferation increases
Solution Approach 1:
The mobile communication device acts as a controlled intermediary that manages media transmission. It receives media data in a received format, converts it to a displayable format, and transmits only the necessary data to the display device. This controlled intermediary approach prevents unauthorized proliferation while maintaining compatibility, as the mobile device can selectively manage which devices receive media and in what formats.
Solution Approach 2:
The patent employs parameter changes in the media data format during transmission. The mobile communication device converts media from a received format suitable for mobile devices to a displayable format optimized for larger screens. This format conversion process allows the same media content to be efficiently transmitted to different device types without creating unnecessary copies, thereby reducing proliferation while maintaining broad compatibility.
3Ease of operation
If mobile phone displays media directly, then convenience is improved, but presentation quality deteriorates
Solution Approach 1:
The patent merges the mobile communication device's wireless communication capability with an external display device's high-resolution screen. The mobile device maintains its portability and ease of operation while leveraging the external display's superior resolution and screen size for media presentation. This combination allows users to enjoy both the convenience of mobile devices and the quality of desktop displays without sacrificing either attribute.
