Wireless AV Transmission via Interface Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems do not support communication when an AV source and an AV sink use different AV interfaces or different information types such as video, audio, and control messages through the same or different interfaces.
Innovation Solution
The solution involves wireless transmission of audio/video information via different wired AV interface formats, where interface-dependent processing is applied to separate and convert AV information types, allowing communication between AV devices with different interfaces, using a wireless transceiver to transmit processed information between AV devices with different wired AV interfaces.

Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional wireless transmission system uses a single AV interface type, then the system structure is simple, but it cannot support communication between AV devices with different AV interfaces
Solution Approach 1:
The patent introduces an interface adaptation layer as an intermediary component that sits between the wireless transmission protocol and different AV interfaces (HDMI, DisplayPort, DVI). This adaptation layer translates and converts data packets to match the specific protocol requirements of each interface type, enabling the system to communicate with multiple different interface types without requiring separate dedicated systems for each interface.
Solution Approach 2:
The wireless transmission system is designed with a universal architecture that can handle multiple AV interface types through a single unified platform. The system includes a configurable data packet structure and protocol conversion capabilities that allow it to adapt to different interface requirements (HDMI, DisplayPort, DVI) dynamically, making one system perform multiple interface functions rather than requiring separate specialized systems.
2Adaptability or versatility
If the system separates different information types (video, audio, control messages) through the same interface, then communication flexibility improves, but the processing complexity increases
Solution Approach 1:
The patent segments different types of information (video data, audio data, control messages) into separate data packets with distinct headers and identifiers. Each packet type is processed through dedicated handling routines that extract, route, and transmit the appropriate information through the wireless interface. This segmentation allows the system to manage multiple information types simultaneously while maintaining organized processing streams for each type.

AI summary
A method and system is provided for wireless transmission of audio/video information via different wired AV interface formats. A method and system for wireless communication of audio/video AV information between AV devices includes receiving audio/video (AV) information from a first AV module via a first wired AV interface in a first AV device, applying interface dependent processing to the AV information, and transmitting the processed AV information from a wireless transceiver over a wireless channel to a wireless receiver of a second AV device. The second AV device includes a second wired AV interface and the first AV interface is of a different type than the second interface device.
