Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connection is used for image data transmission, then data transmission reliability is improved, but aesthetic appearance and mobility are worsened
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system. The electronic apparatus uses a communication device to transmit image data, audio data, and metadata wirelessly to the display apparatus, eliminating the need for physical cables and connectors while maintaining data transmission functionality.
2Stability of the object's composition
If wired connection is used for image data transmission, then data transmission stability is improved, but device mobility is worsened
Solution Approach 1:
The patent substitutes the mechanical cable-based transmission system with a wireless communication system using communication devices. This allows the electronic apparatus and display apparatus to transmit data without physical connections, enabling easier movement and repositioning of devices while maintaining stable data transmission through wireless protocols.
3Shape
If wireless connection is used for data transmission, then aesthetic appearance and mobility are improved, but data transmission speed is worsened
Solution Approach 1:
The patent segments the image content into three distinct data types: image data, audio data, and metadata. Each type is processed and transmitted separately through the wireless communication system. This segmentation allows for optimized transmission of each data type, improving overall transmission efficiency and speed while maintaining aesthetic appearance through wireless connection.
Solution Approach 2:
The patent changes the transmission parameters by separating different data types (image, audio, metadata) and transmitting them with appropriate prioritization and processing. Image data is transmitted with high priority to ensure quality, while audio and metadata are handled with optimized parameters for their specific requirements, thereby improving overall data transmission speed through parameter optimization.
4Ease of operation
If wireless connection is used for data transmission, then device mobility is improved, but data transmission bandwidth is worsened
Solution Approach 1:
The patent divides the total data transmission into three separate streams: image data, audio data, and metadata. This segmentation allows the wireless communication system to allocate bandwidth efficiently to each data type, ensuring that high-bandwidth image data receives sufficient capacity while audio and metadata use less bandwidth, thereby managing overall bandwidth requirements for mobile wireless operation.
Solution Approach 2:
The patent optimizes transmission parameters for each data type, adjusting bandwidth allocation dynamically. Image data is transmitted with higher bandwidth priority to maintain quality, while audio and metadata use optimized lower bandwidth parameters. This parameter adjustment enables effective wireless data transmission with limited bandwidth availability.

AI summary
An electronic apparatus may include: an input/output interface configured to receive digital image content that is not compressed; a communication device configured to transmit and receive data wirelessly; at least one memory storing instructions; and at least one processor configured to obtain packet data corresponding to the digital image content and control the communication device to transmit the packet data. The at least one processor may be further configured to execute the instructions to: separate video information, audio information, and meta information in the digital image content; perform encoding in preset units of blocks using the video information in preset units of lines among the video information to obtain encoded video information; packetize each of the encoded video information, the audio information, and the meta information to obtain the packet data; and control the communication device to wireless transmit the packet data to a display device.
