IP-Based Broadcast Signal Transmission Apparatus for DVB and DVB-I Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital broadcast signal transmission technologies fail to provide a unified user experience across terrestrial, satellite, and cable channels, and lack efficient methods for integrating Internet-based channels with traditional linear channels, limiting the ability to switch between DVB and DVB-I networks on the same channel.
Innovation Solution
The implementation of an IP-based broadcast signal transmission and reception apparatus that uses open Internet-based native code to provide a unified user experience, enabling channel guides and service initialization methods for Internet channels, and allowing switching between DVB and DVB-I networks on the same channel, while supporting super ultra-high definition (SUHD) linkage through standard definition (SD), high definition (HD), and ultra-high definition (UHD) services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional digital broadcast signal transmission technologies are used, then service transmission is possible, but unified user experience across terrestrial, satellite, and cable channels cannot be provided
Solution Approach 1:
The patent implements a universal service interface that allows the same service to be delivered across multiple broadcast networks (terrestrial, satellite, cable) through a common protocol stack. The reception apparatus uses a unified service access mechanism that works across different network types, providing consistent user experience without requiring separate handling for each network type.
Solution Approach 2:
The patent introduces an IP-based intermediary layer that mediates between traditional broadcast transport streams and modern IP-based services. This intermediary enables seamless integration of DVB and DVB-I networks by translating and harmonizing protocols, allowing services to flow uniformly across different network infrastructures.
2Adaptability or versatility
If Internet-based channels are integrated with traditional linear channels, then service accessibility is improved, but efficient switching between DVB and DVB-I networks becomes complex
Solution Approach 1:
The patent merges DVB and DVB-I networks into a unified broadcast infrastructure where both network types operate simultaneously. Services are delivered through both traditional transport streams and IP-based streams on the same physical infrastructure, enabling automatic switching without user intervention and simplifying operation while expanding service accessibility.
3Adaptability or versatility
If channel switching between DVB and DVB-I networks is enabled, then service variety is increased, but transmission and reception complexity increases
Solution Approach 1:
The patent segments the broadcast system into independent functional modules: a service delivery layer that handles multiple network protocols, a transport layer that manages stream switching, and a presentation layer that delivers unified service output. This segmentation allows service variety to be maintained while reducing overall system complexity through modular architecture.

AI summary
Abstract: A broadcast signal reception apparatus according to embodiments of the present invention comprises: a tuner for receiving a broadcast signal, wherein the broadcast signal includes a first content received through a first network and a second content received through a second network, the first content and the second content are allocated to a first channel, and the first content has a resolution different from that of the second content; a signaling parser for parsing signaling information included in the broadcast signal, wherein the signaling information includes linkage information between the first content and the second content; a controller for controlling the first content and the second content on the basis of the signaling information; and a decoder for decoding at least one of the first content or the second content.
