Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a display/interface device that offers the usability characteristics of a tablet PC with augmented processing power, while enabling video sharing with other devices and real-time switching between video streams, which existing technologies do not adequately address due to limitations in processing capacity and energy storage of tablet PCs and the demand for higher performance in wireless communication.
Innovation Solution
A video display unit that can receive video signals through both wired and wireless signal paths, allowing for seamless switching between video streams from matched and non-matched computing platforms, using a video stream switching controller to manage authentication, authorization, and decoding, and employing spatial to frequency transforms to optimize coefficient transmission for efficient video data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If video signals are transmitted wirelessly to a larger screen, then display quality and viewing experience are improved, but data rate requirements and processing capacity demands increase
Solution Approach 1:
The video signal transmission system is segmented into multiple independent signal paths (wired and wireless), allowing the system to distribute processing and transmission loads across different channels, thereby managing high data rate requirements without compromising display quality
Solution Approach 2:
The display unit is designed with multi-functionality to receive and process video signals through both wired and wireless paths, enabling it to handle various data rate requirements while maintaining consistent display quality across different transmission modes
2Ease of operation
If tablet PCs are used for video transmission, then portability and usability are improved, but processing capacity and energy storage are limited
Solution Approach 1:
A display unit serves as an intermediary device between the tablet PC and the final display output. The tablet maintains its portability while the display unit handles the computationally intensive tasks of receiving, processing, and rendering high-definition video signals
Solution Approach 2:
The display unit autonomously manages video signal processing, authentication, and rendering tasks, freeing the tablet PC from heavy processing burdens while maintaining seamless video transmission capability
3Adaptability or versatility
If multiple video signal paths are implemented, then video sharing and switching capability are improved, but device complexity increases
Solution Approach 1:
Multiple video signal paths (wired and wireless) are merged into a unified reception system with a single display output. The system combines different transmission channels and automatically manages signal routing, enabling video sharing across multiple devices while presenting a simplified user interface

AI summary
Disclosed are methods, circuits, devices and associated executable code for facilitating transmission, reception and presentation (e.g. rendering) of video information/signals on a video display unit such as a flat-screen display, a touchscreen and/or a tablet computing platform. There may be provided a video display unit adapted to receive video signals through two or more video signal paths, wherein one of the signal paths (i.e. a first signal path) may be a wired signal path. Another signal path (i.e. a second signal path) may be a wireless signal path. The display unit may be matched or paired to a matched computing platform. The paired matched computing platform may send video signals to the display unit along the wired signal path, e.g. when the display unit is docked with the matched computing platform. The paired matched computing platform may send video signals to the display unit along the wireless signal path, e.g. when the display unit is disconnected from the matched computing platform.
