Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If expensive high-end equipment is used to process and edit multiple video and audio signals in real time, then the quality of relay broadcasting content is improved, but the cost and device complexity increase significantly
Solution Approach 1:
The patent segments the relay broadcasting system into multiple mobile device participants, each contributing video and audio signals. Instead of using one complex high-end processing device, the system divides the workload across multiple simpler mobile devices, with each device capturing and transmitting its own signals independently to a server for centralized processing.
Solution Approach 2:
The patent uses sampling technology to create simplified copies of video and audio signals. Mobile devices capture full-resolution signals but transmit compressed sampling versions to the server. The server then selectively requests full-quality copies only for segments that require editing, reducing the need for continuous high-bandwidth transmission of all signals at full quality.
2Manufacturing precision
If mobile devices attempt to process and edit multiple video and audio signals locally, then the quality of relay broadcasting content can be maintained, but the computing resources required exceed mobile device capabilities
Solution Approach 1:
The patent moves the heavy processing workload from the mobile device dimension to the server dimension. Mobile devices are limited to lightweight tasks of capturing signals and transmitting sampling data, while the server handles the computationally intensive editing and rendering of relay broadcasting content, leveraging its superior processing power and resources.
Solution Approach 2:
The patent extracts the complex editing and processing functions from mobile devices and concentrates them on the server. Mobile devices only perform signal acquisition and basic transmission, while the server takes over all heavy lifting of video/audio synchronization, editing, rendering, and quality management, leaving mobile devices with minimal computing burden.
3Manufacturing precision
If full-quality video and audio data is transmitted from all mobile devices for editing, then the quality of relay broadcasting content is maintained, but the data transmission load becomes unmanageable
Solution Approach 1:
The patent applies partial action by transmitting only sampling-quality video and audio data from mobile devices instead of full-quality data. This partial transmission is sufficient for the server to identify which segments require full-quality copies for editing, avoiding the need to continuously transmit all full-quality signals from all devices.
Solution Approach 2:
The patent performs preliminary transmission of sampling data before determining which full-quality copies are needed. Mobile devices continuously send compressed sampling versions of their signals to the server, allowing the server to pre-analyze and identify segments requiring high-quality editing, and only then request full-quality copies from specific devices for those specific segments.

AI summary
Provided are a method, device, and non-transitory computer-readable recording medium for supporting relay broadcasting using a mobile device. It is possible to reduce a computing load of a repeater device by distributing a computing load required to produce relay broadcasting content to a plurality of photographer devices and thus widen the range of photographer devices that may participate in relay broadcasting.
