Media Processing Device Service Discovery via IP Aggregation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current broadcast signal transmission and reception technologies face challenges in providing a seamless Internet protocol (IP)-based TV service that mimics the user experience of terrestrial, satellite, and cable linear channels, especially in scenarios involving over-the-top (OTT) devices and internet protocol television (IPTV), without the need for traditional tuners or set-top boxes.
Innovation Solution
A media processing device that includes a receiver for service discovery and a processor for transmitting and displaying services, utilizing a service list server to aggregate and manage services, enabling IP-based broadcast service discovery and acquisition over broadband networks, and providing a unified user interface for traditional and OTT services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional tuners and set-top boxes are used for broadcast signal reception, then reliable service delivery is ensured, but device complexity and cost increase
Solution Approach 1:
The patent extracts the service list information from traditional broadcast signals and delivers it separately through IP-based networks. The receiver extracts service lists from IP packets and processes them independently, separating the service guide function from the traditional tuner architecture, thereby reducing device complexity while maintaining reliability
Solution Approach 2:
The patent introduces an intermediary service list structure that bridges traditional broadcast services and IP-based delivery. The service list acts as a mediator containing service identifiers, URLs, and metadata that enables IP-based receivers to access broadcast services without traditional tuners, resolving the contradiction between reliability and device complexity
2Adaptability or versatility
If service lists are transmitted over IP networks, then adaptability to Internet-based devices is improved, but service discovery complexity increases
Solution Approach 1:
The patent segments service information into structured service lists containing discrete elements such as service identifiers, URLs, metadata, and validity periods. This segmentation allows IP-based devices to selectively process and discover services based on their capabilities, reducing service discovery complexity while improving adaptability
Solution Approach 2:
The patent changes the delivery parameters of service information from traditional broadcast protocols to IP-based protocols. Service lists are transmitted as IP packets with standardized formats including service identifiers, content URLs, and metadata parameters, enabling seamless adaptation to Internet-based devices while maintaining organized service discovery processes
3Loss of information
If aggregated service lists are received, then service information completeness is improved, but data processing time increases
Solution Approach 1:
The patent implements periodic service list updates with validity period indicators. Receivers can determine when service lists are updated and process only changed portions rather than entire aggregated lists continuously. The service list includes timestamp and version information enabling selective processing, reducing data processing time while maintaining service information completeness
Solution Approach 2:
The patent performs preliminary organization of service information into structured lists with identifiers, URLs, and metadata before transmission. This preliminary structuring allows receivers to efficiently parse and process service information without dealing with unorganized data, reducing processing time while preserving complete service information
