Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If MPEG-DASH is used to transmit media content over internet networks, then adaptability to variable bandwidth conditions is improved, but transmission efficiency and service integration with existing broadcasting systems deteriorates
Solution Approach 1:
The patent combines MPEG-DASH internet-based adaptive streaming with existing broadcasting networks by introducing a gateway that bridges the two systems. The gateway receives MPD metadata from internet servers and delivers it to broadcasting receivers, enabling seamless integration of DASH services with traditional broadcasting infrastructure while maintaining adaptability to bandwidth variations.
Solution Approach 2:
The patent introduces a gateway as an intermediary component that mediates between internet-based DASH servers and broadcasting network receivers. This gateway translates and forwards MPD metadata, enabling efficient service integration without requiring fundamental changes to either the DASH protocol or existing broadcasting systems, thereby improving overall transmission efficiency.
2Adaptability or versatility
If MPEG-DASH services are integrated with existing broadcasting services, then service versatility is improved, but device complexity increases
Solution Approach 1:
The patent extracts the complex MPD metadata processing functionality from individual receivers and centralizes it in a gateway. This extraction reduces the complexity burden on end-user devices while maintaining service versatility, as the gateway handles the computationally intensive tasks of receiving, parsing, and forwarding DASH metadata.
Solution Approach 2:
The gateway acts as an intermediary that shields receivers from the complexity of DASH protocol implementation. By handling all interactions with internet-based DASH servers and translating responses into broadcasting network formats, the gateway enables service versatility without requiring receivers to become more complex.
3Adaptability or versatility
If MPD metadata is transmitted through broadcasting networks, then network compatibility is improved, but transmission speed deteriorates
Solution Approach 1:
The patent segments the MPD metadata transmission process into two parts: large-volume metadata is transmitted through the high-speed internet connection, while only essential forwarding information is transmitted through the broadcasting network. This segmentation allows compatibility with broadcasting networks while maintaining overall transmission speed through intelligent use of available pathways.
Solution Approach 2:
The patent introduces a dual-path transmission dimension by utilizing both internet networks and broadcasting networks simultaneously for different aspects of MPD metadata delivery. This multi-dimensional approach allows the system to leverage the high speed of internet for bulk data transfer while using broadcasting networks for compatible device reachability.
