Portable A/V Relay Device Wireless Signal Re-transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing A/V systems restrict viewers to a limited area as they are typically fixed relative to the playback components, preventing seamless A/V signal reception and display on mobile devices without direct line of sight.
Innovation Solution
A portable A/V relay device that receives an A/V signal from an original source, converts it to a digital format, and re-transmits it wirelessly using a short-range RF protocol or IP network, allowing compatible external playback devices to decode and display the signal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If A/V systems use fixed playback components, then signal quality is maintained, but viewer mobility is restricted to a limited area
Solution Approach 1:
The patent introduces a portable relay device as an intermediary between the fixed A/V source and the mobile playback device. This relay device receives the A/V signal wirelessly, processes it, and re-transmits it to the mobile device, enabling viewers to move freely while maintaining signal quality through the relay's buffering and re-transmission capabilities
Solution Approach 2:
The patent adds a wireless communication dimension to the traditional fixed A/V system by incorporating wireless receivers and transmitters. This allows the signal to be transmitted through multiple spatial dimensions rather than being constrained to a fixed physical connection, enabling viewer mobility while maintaining signal integrity
2Adaptability or versatility
If A/V signals are transmitted wirelessly to mobile devices, then viewer mobility is enabled, but signal interference and loss may occur
Solution Approach 1:
The relay device incorporates buffering memory that stores A/V signals before re-transmission. This buffering acts as a cushion against signal loss and interference, allowing the system to recover from temporary wireless disruptions without losing A/V content quality or continuity
Solution Approach 2:
The relay device creates a copy of the received A/V signal, processes this copy, and re-transmits it to the mobile device. This copying mechanism allows the original signal to be preserved and processed separately, enabling error correction and quality maintenance during wireless transmission
3Adaptability or versatility
If multiple devices share the same A/V source, then accessibility is improved, but bandwidth and signal resources are divided
Solution Approach 1:
The relay device segments the A/V signal into separate data streams that can be independently transmitted to multiple mobile devices. By dividing the signal processing into discrete packets and using wireless communication protocols, the system can serve multiple viewers simultaneously without degrading the overall signal quality or bandwidth availability
