Network Video Streaming Display Discovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional display systems require pre-determined physical connections between image generators and displays, limiting flexibility and scalability, especially in environments where broadcast mechanisms are not supported or efficient, and do not allow for dynamic mapping of image generators to multiple display targets.
Innovation Solution
A packet-switched video streaming system that enables image generators to discover and connect to available displays through a network, using network video processor modules and display listing modules to manage display availability and connection requests, allowing for dynamic mapping and selection based on various constraints such as security, proximity, and display capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional physical hardware connections are used to map video sources to displays, then the connection stability is improved, but the system flexibility and adaptability deteriorate
Solution Approach 1:
The patent introduces a network as an intermediary between video sources and displays, replacing direct physical connections with network-based communication. This allows displays to be discovered and connected dynamically through network protocols while maintaining stable connections once established, resolving the contradiction between connection stability and system flexibility
Solution Approach 2:
The system transitions from static physical connections to dynamic network-based connections. Displays can be discovered, connected to, and disconnected from programmatically through network protocols, allowing the mapping between video sources and displays to change dynamically based on operational needs while maintaining connection stability when active
2Ease of operation
If broadcast mechanisms are used for display device discovery, then the ease of operation is improved, but the scalability and network compatibility deteriorate
Solution Approach 1:
The display discovery process is segmented into multiple phases: initial display announcement to the network, active scanning by image generators for discovered displays, and formal connection establishment. This segmentation allows the system to work with or without broadcast capabilities, improving both ease of operation and network compatibility
Solution Approach 2:
The system implements feedback mechanisms where displays announce their availability to the network and image generators can query and discover these displays. This feedback loop enables automatic display discovery and connection management, making the system easy to operate while being adaptable to different network types that may or may not support broadcast
Data Source
AI summary
A method for creating a list of display devices that are available to receive a video signal from an image generator via network video streaming. One version of the method includes transmitting a display availability packet indicating one or more of the display devices that are available for connection, updating a network display listing module with the information stored in the display availability packet, and transmitting an availability request packet requesting a list of the display devices that are available to receive the video signal. In response to receiving an availability request packet, a display resource list, indicating the display devices available to receive the video signal, is generated from the metadata contained in the availability request packet.
