Network Platform for Multi-Perspective Audio Video Signal Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional television broadcasting methods are costly and restrictive, requiring expensive equipment and personnel for live broadcasts, and do not allow for personalized viewer experiences, as they typically involve synthesizing multiple signals into a single program for passive reception.
Innovation Solution
A network-platform based system for collecting, transmitting, editing, and integrating audio and video signals from multiple sources, allowing for multi-perspective video selection and personalized viewing experiences through high-speed broadband networks and innovative audio/video collecting terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traditional live broadcast pattern is used with mobile control room, then signals can be transmitted in real time, but transmission cost and equipment complexity increase significantly
Solution Approach 1:
The patent extracts the mobile control room from the broadcasting system, allowing cameras to transmit signals directly to the television station without requiring an intermediate control room. This eliminates the need for complex switching and synthesis equipment at the field location, reducing overall system complexity while maintaining real-time transmission capability.
Solution Approach 2:
The patent introduces a network platform as an intermediary between cameras and television stations. This platform receives signals from multiple cameras simultaneously and makes them available to directors at the station, replacing the traditional mobile control room function and simplifying the broadcasting system architecture.
2Adaptability or versatility
If multiple transmission lines are rented to provide more materials, then program quality and comprehensiveness improve, but transmission cost increases
Solution Approach 1:
The patent merges multiple camera signals into a single transmission stream by having all cameras connect to a common network platform. Directors at the television station can then access and select from multiple signals without requiring separate transmission lines for each camera, reducing transmission costs while maintaining program material variety.
Solution Approach 2:
The network platform serves multiple functions: receiving signals from multiple cameras, storing signals for later use, and providing signals to multiple directors simultaneously. This multi-functional approach replaces the need for multiple dedicated transmission lines, achieving versatility without proportional cost increase.
3Loss of energy
If signals are synthesized into a single program, then transmission cost is reduced, but program material waste and quality degradation occur
Solution Approach 1:
The patent performs preliminary action by having the network platform receive and store all camera signals before they reach the director. This allows directors to select from the complete set of available signals without pre-synthesis, ensuring no program material is wasted while maintaining cost-effective single-stream transmission.
Solution Approach 2:
The system provides feedback to directors about available signals and their characteristics, enabling informed selection decisions. This ensures that signals are not synthesized in advance but are made available on-demand, preventing material waste while keeping transmission costs low.
4Ease of operation
If traditional broadcasting method is used, then content delivery is straightforward, but viewer personalization and interactivity are limited
Solution Approach 1:
The patent introduces dynamics by allowing viewers to actively select and switch between different camera perspectives and audio sources during program playback. The system transitions from static, pre-synthesized programs to dynamic, viewer-configurable content streams, enabling personalization while maintaining simple content delivery through the network platform.
