Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all media streams are centralized and handled through a single host device, then device integration is achieved, but the host device becomes overloaded with high bandwidth video processing and complex network algorithms
Solution Approach 1:
The patent segments the media processing responsibilities by allowing peripheral devices (cameras, microphones, displays) to transmit and receive media streams directly through wireless connections, rather than routing all streams through a central host device. This divides the processing load across multiple devices, reducing the burden on the host while maintaining system integration.
Solution Approach 2:
The patent extracts the media transmission function from the host device and assigns it directly to peripheral devices. By eliminating the requirement for peripherals to route media through the host, the system removes the processing bottleneck from the host device while maintaining coordinated control through clock synchronization and capability coordination.
2Reliability
If wired connections are used between host device and peripherals, then stable data transmission is achieved, but mobility and seamless device integration are restricted
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system. By using wireless protocols for media transmission between peripherals and the host device, the system eliminates physical cable constraints while maintaining reliable data transmission through protocol-level synchronization and error handling mechanisms.
3Ease of operation
If advanced wireless technologies are utilized, then mobility and device integration are improved, but CPU and network capabilities of existing devices become insufficient
Solution Approach 1:
The patent segments the processing requirements by allowing computationally intensive media encoding and wireless transmission to occur at the peripheral devices themselves, rather than requiring the host device to handle all processing. This distributes the CPU and network load across multiple devices, making advanced wireless capabilities accessible even when the host device has limited processing power.
4Extent of automation
If a host device aggregates all media streams, then centralized control is achieved, but the system complexity and hardware requirements increase
Solution Approach 1:
The patent extracts the media aggregation function from the host device and allows peripheral devices to operate independently with direct wireless connections. The host device retains automated control through clock synchronization and capability coordination, but eliminates the complex hardware and software required for media stream aggregation and processing.
Data Source
AI summary
Disclosed herein are systems, methods, and non-transitory computer-readable storage media for detect adjunct peripherals, and coordinating their media capabilities (as a preparation to be able to signal their capabilities). The host device and the peripherals can synchronize wall clocks. The system sets up a call (or receive a call) from a remote host device, and requests the peripherals to check for network connectivity to the remote host device (connectivity check). This check can be done by using a STUN/TURN procedure. The system establishes direct connectivity between the peripherals and the remote host device and monitors lip sync by transferring RTCP messages between the host device and the peripherals and instructing display and playback peripherals/sub systems to align lip sync.
