Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dedicated boards corresponding to a variety of required specifications are manufactured, then the video signal transmission system can handle diverse specifications (pixel count, aspect ratio, data transmission rate), but total cost of design and manufacture increases
Solution Approach 1:
The patent implements a universal video signal transmission system where a single board configuration can handle multiple specifications through software-based packetizing processing. The packer unit dynamically adjusts packet configuration parameters (number of pixels per video signal, number of tone bits) based on the required specification, eliminating the need for dedicated hardware boards for each specification while maintaining full adaptability to diverse display requirements including different pixel counts, aspect ratios, and data transmission rates
2Adaptability or versatility
If dedicated boards corresponding to a variety of required specifications are manufactured, then the video signal transmission system can handle diverse specifications, but power consumption increases
Solution Approach 1:
The system uses a single universal board with configurable packetizing processing that adapts to different specifications through software control rather than hardware reconfiguration. The packer unit adjusts packet configuration parameters dynamically, allowing one board to replace multiple dedicated boards, thereby significantly reducing overall power consumption while maintaining specification adaptability
3Adaptability or versatility
If the number of wires between video signal transmission device and receiving device is increased, then more specifications can be handled, but cost increases significantly
Solution Approach 1:
The patent applies segmentation by dividing the video signal into packet-configured blocks that can be efficiently transmitted through a fixed number of wires. The packer unit segments the video signal according to configurable parameters (number of pixels per video signal, number of tone bits), allowing flexible specification handling while maintaining a constant wire count between transmission and receiving devices
Solution Approach 2:
The system changes packet configuration parameters (number of pixels per video signal, number of tone bits, packet size) to adapt to different specifications without changing the physical wire count. This parameter-based flexibility allows the same hardware configuration to support diverse display requirements including different resolutions, aspect ratios, and data transmission rates

AI summary
The present invention relates to a video signal transmission device and the like that can support a variety of system specifications. The device includes a packer unit, an encoder unit, and a serializer. The packer unit generates, from a video signal of one or more pixels, a plurality of block signals having a packet configuration of size corresponding to the number of pixels and the number of tone bits of a color signal constituting a video signal. At this time, a control signal including a pulse having a width corresponding to the number of pixels and the number of tone bits is also generated. The encoder unit applies encoding processing having encoding efficiencies that are different between a first period and a second period of a control signal that are distinguished depending on existence or non-existence of a pulse to the block signals.
