Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If processing tasks are concentrated in a single device (PC or display device), then device complexity is reduced and ease of operation is improved, but processing efficiency deteriorates and audiovisual quality worsens due to insufficient processing power
Solution Approach 1:
The patent segments the audiovisual processing tasks by dividing them into complementary signal processing functions. The display device performs functions such as video decoding and image processing, while the PC performs audio decoding and signal processing. This segmentation allows each device to handle specific tasks for which it is optimized, thereby improving overall processing efficiency without requiring one device to have excessive complexity.
Solution Approach 2:
The system implements multi-functionality by enabling both the PC and display device to participate in audiovisual processing. The display device not only displays video but also decodes video streams and performs image processing. The PC not only handles user interactions but also decodes audio and performs signal processing. This universal approach allows distributed processing across multiple devices, improving productivity while maintaining manageable complexity for each individual device.
2Speed
If a single device performs all processing tasks, then the system is easier to operate and control, but processing speed and quality deteriorate due to limited processing power and the presence of artifacts
Solution Approach 1:
Processing speed is improved by segmenting tasks across devices with appropriate capabilities. The display device handles video-intensive tasks (decoding and image processing) leveraging its dedicated hardware, while the PC handles audio processing. This segmentation enables parallel processing that increases overall speed while maintaining operational simplicity through automated task distribution based on device capabilities.
3Manufacturing precision
If processing capabilities are available in multiple platforms, then processing power increases and quality improves, but device complexity and coordination requirements increase
Solution Approach 1:
The patent merges the processing capabilities of multiple platforms (PC and display device) into a coordinated system. The display device performs video decoding and image processing, while the PC performs audio decoding and signal processing. The devices are connected via a network interface that enables seamless data exchange and synchronization. This merging of capabilities improves audiovisual quality by utilizing the combined processing power of both devices while managing coordination complexity through standardized communication protocols.
4Productivity
If distributed processing is implemented across multiple devices, then processing efficiency and quality improve, but network communication requirements and data transmission complexity increase
Solution Approach 1:
The system achieves distributed processing efficiency by implementing multi-functionality in both devices. The display device serves as both a display and a video decoding/processing unit, while the PC serves as both a user interface and an audio processing unit. This universal approach enables efficient distributed processing while managing network coordination complexity through leveraging existing network capabilities and standardized communication protocols.

AI summary
A method of distributing audio and video processing tasks among devices interconnected to a display device via a local network is disclosed. In one embodiment, the display device offloads some processing tasks to a computing device on the local network to achieve improved processing performance. The computing device receives audiovisual data, decodes, processes, encodes and transmits the encoded data to the display device in a suitable data format. The processing in the computing device is complementary to any processing to be performed in the display device. In another embodiment, the display device utilizes a plurality of devices on the local network to perform particular signal processing tasks. The other devices in network perform the processing tasks indicated by the display, and send processed data back to the display device for presentation, which helps improve the overall audiovisual data processing performance.
