Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual modules are constructed for each type of digital stream, then protocol compliance and electrical characteristics are ensured, but device complexity and lack of flexibility increase
Solution Approach 1:
The patent implements a universal interface unit that can handle multiple digital stream types (MPEG2, MPEG4, MPEG7, DVB, ATSC, HDTV) through a single device. The data converter is configured to meet different data transmission protocols through software programming, eliminating the need for separate hardware modules for each stream type while maintaining protocol compliance.
Solution Approach 2:
The interface unit employs dynamic reconfiguration capability where the data converter can be programmatically adjusted to meet different electrical and protocol requirements for various digital stream types. This dynamic adaptation allows the same hardware to function differently based on the required stream format, reducing device complexity while ensuring reliability.
2Manufacturing precision
If separate modules are used for different digital stream types, then specific electrical characteristics are met, but adaptability and versatility decrease
Solution Approach 1:
The interface unit is designed as a universal device that can process multiple digital stream types including MPEG2, MPEG4, MPEG7, DVB, ATSC, and HDTV formats. The data converter uses programmable configuration to adapt to different electrical characteristics and protocol requirements, providing both manufacturing precision and adaptability through a single versatile platform.
Solution Approach 2:
The patent utilizes parameter changes by allowing the data converter to be reconfigured through software to meet different electrical and protocol parameters for various digital stream types. This enables the same hardware to adapt its electrical characteristics and processing behavior dynamically based on the required stream format.
3Reliability
If individual modules are constructed for each stream type, then protocol requirements are met, but ease of operation and configuration simplicity worsen
Solution Approach 1:
The universal interface unit consolidates multiple protocol-handling capabilities into a single device with programmable data converter. Users can operate the same hardware for different digital stream types without dealing with multiple separate modules, simplifying configuration while maintaining protocol compliance through software-based adaptation.

AI summary
An interface (4) between a digital device (6) for transmitting and/or receiving a digital stream and a computer (2) comprises a digital stream transmitter/receiver (transceiver) (20), a computer bus interface (12) and a data converter (14, 16&18). The digital transceiver transmits digitally streamed content and/or receives digitally streamed content to/from the digital device. The computer bus interface receives/provides data to/from a computer bus of a computer for use by the computer and/or as provided by the computer. The data converter converts data received by the digital stream receiver into data useable by the computer from the computer bus and/or converts data received by the computer bus interface into digitally streamed data for transmission by the digital stream transmitter.
