IP TV Service Lists for Unified Channel Discovery and Streaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods lack the ability to provide an IP-based TV service with the same user experience as terrestrial, satellite, or cable linear channels, integrate a channel guide with open Internet-based native code reception, and support seamless real-time/non-real-time media streaming across various platforms, while also addressing issues with service discovery and signaling in Internet-based broadcast services.
Innovation Solution
A media data processing device and method that enables IP-based TV services by generating and transmitting media data and service lists over a network, allowing receivers without traditional tuners to discover and acquire Internet-based broadcast services, and providing a unified platform for OTT content without requiring separate apps, while managing service versions and parsing selectively to optimize service delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an IP-based TV service is implemented using conventional methods, then Internet broadcasting service can be provided, but the user experience cannot match terrestrial, satellite, or cable linear channels
Solution Approach 1:
The patent implements a universal service list structure that works across multiple broadcast systems (terrestrial, satellite, cable, and Internet-based). The service list contains standardized fields that can represent different service types uniformly, allowing a single receiver to handle diverse broadcast sources with consistent user experience, thereby achieving both adaptability and reliability
2Adaptability or versatility
If an application-based linear channel service is used, then Internet broadcasting can be accessed, but a integrated channel guide with terrestrial, satellite, or cable channels cannot be provided
Solution Approach 1:
The patent merges channel guide functionality for terrestrial, satellite, cable, and Internet-based channels into a unified service list structure. By combining these previously separate guide systems into a single standardized format, the invention enables integrated channel guides without requiring complex separate application architectures, thus reducing device complexity while improving adaptability
3Loss of information
If the entire service list is received for versioning/expiration management, then complete service information is available, but reception efficiency is reduced
Solution Approach 1:
The patent extracts and manages version and expiration information at the service list level rather than requiring reception of entire service lists. By separating this critical metadata for independent management, the system maintains complete service information awareness while significantly improving reception efficiency, as receivers can update only the essential version/expiration data without receiving full service list contents
