A/V Hub HDMI Content Arbitration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing entertainment devices face challenges in simultaneously displaying high-definition multimedia-interface (HDMI) content due to interface circuit and communication bandwidth limitations, and user interfaces are often cumbersome and difficult to navigate, leading to user frustration.
Innovation Solution
An audio/video (A/V) hub that communicates with A/V display devices and content sources, providing display instructions and managing HDMI content transmission, including transcoding and dynamic user interface adaptation based on device states and formats, to simplify content selection and display management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple content sources are connected to an entertainment device, then content variety is improved, but interface complexity and user operation difficulty increase
Solution Approach 1:
The patent introduces a portable electronic device (smartphone, tablet, or remote control) as an intermediary between the user and the entertainment device. This intermediary device displays a simplified user interface that shows content sources and playback controls, allowing users to select and control content without navigating the complex native interface of the entertainment device. The portable device receives communication from the entertainment device and relays user selections back, effectively mediating the interaction and reducing operational complexity.
2Manufacturing precision
If high-definition content is transmitted through interface circuits, then content quality is improved, but communication bandwidth limitations cause transmission delays
Solution Approach 1:
The patent replaces the traditional direct HDMI connection and native interface control mechanism with a wireless communication system. The entertainment device communicates with the portable electronic device via wireless protocols (WiFi, Bluetooth, or other wireless standards), allowing high-definition content to be transmitted and controlled without the physical constraints and bandwidth limitations of traditional wired interfaces. This substitution enables flexible, high-quality content transmission while reducing the complexity of physical connections.
Data Source
AI summary
An audio/video (A/V) hub is described. This A/V hub determines display instructions specifying information to be displayed on a display in an A/V display device that includes icons associated with content sources. These content sources are located at arbitrary or different locations in a structure, including locations external to an environment of the A/V hub and the A/V display device. Then, the A/V hub provides the display instructions to the A/V display device for display on the display.
