Multi-Screen Interactive Data Display via Dual Protocol Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projection technologies only support the projection of audio and video data, limiting the types of content that can be displayed and resulting in poor interactivity between devices.
Innovation Solution
Establishing an interactive data connection channel using a different protocol (UDP) for transmitting interactive data, allowing for the analysis and display of various interactive data types such as text, pictures, and special effects, in addition to audio and video, by querying and applying rules from a preset interactive data connection channel information table.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing projection technology is used to transmit audio and video data, then audio and video content can be projected, but the types of content that can be displayed are limited and interactivity is poor
Solution Approach 1:
The patent segments the data transmission into two distinct channels: an audio and video data connection channel using TCP protocol for reliable media streaming, and an interactive data connection channel using UDP protocol for real-time interactive data exchange. This segmentation allows each channel to be optimized for its specific purpose, enabling diverse content types while maintaining reliable interactivity
Solution Approach 2:
The patent introduces an interactive data connection channel as an intermediary mechanism between the projection terminal and the computing device. This intermediary channel, based on UDP protocol, enables real-time transmission of interactive data (such as user inputs, control commands, and feedback) separate from the main audio and video stream, thereby enhancing interactivity without compromising media quality
2Reliability
If a single TCP protocol is used for data transmission, then reliable connection is established, but transmission speed and responsiveness of interactive data are reduced
Solution Approach 1:
The patent divides the data transmission system into two protocol-based channels: TCP-based channel for audio and video data requiring reliable delivery, and UDP-based channel for interactive data requiring high speed and low latency. This segmentation allows the interactive data to be transmitted faster without the overhead of TCP handshaking and acknowledgment mechanisms
Solution Approach 2:
The patent changes the protocol parameter from TCP to UDP for the interactive data connection channel. This parameter change prioritizes transmission speed and responsiveness over connection reliability, which is acceptable for interactive data where real-time response is more critical than perfect delivery guarantee
