Service List Management for IP-Based Broadcast Discovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no method for implementing an IP-based TV service that provides the same user experience as terrestrial, satellite, or cable linear channels, nor is there an integrated broadcasting system protocol that combines terrestrial, satellite, cable, and Internet-based services, leading to limitations in service discovery and signaling mechanisms.
Innovation Solution
A media data processing method that generates and transmits media data and service lists over a network, allowing receivers without traditional tuners to discover and acquire Internet-based broadcast services, and manages service lists for efficient parsing and storage, enabling seamless real-time and non-real-time media streaming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a receiver without a traditional tuner is used to access Internet-based broadcast services, then device complexity is reduced and adaptability to IP-based networks is improved, but the ability to discover and acquire broadcast services efficiently deteriorates
Solution Approach 1:
The patent introduces a service list as an intermediary data structure that mediates between the IP-based network and the receiver. The service list contains structured information about available broadcast services, including service identifiers, transport stream identifiers, and event information. This intermediary enables receivers without traditional tuners to efficiently discover and acquire Internet-based broadcast services by providing a standardized interface for service information delivery over IP networks.
2Loss of information
If the entire service list is transmitted and received, then complete service information is available, but transmission time and reception processing time increase
Solution Approach 1:
The patent segments the service list into structured components including service-level information, event-level information, and transport stream information. Each segment can be independently processed and stored. The receiver can selectively parse and store only the service segments relevant to its capabilities and current needs, rather than receiving and processing the entire service list, thereby reducing reception time and processing overhead while maintaining access to complete service information when needed.
Solution Approach 2:
The patent enables partial reception and processing of service list information. Receivers can perform selective parsing to acquire only the portions of service information necessary for their operation, such as service identifiers and basic metadata, while deferring or skipping more detailed information. This partial action approach reduces the time and resources required for service list reception while still providing sufficient information for service discovery and acquisition.
3Ease of operation
If app-based linear channel service is used, then service delivery is simplified, but user experience and integration with traditional broadcasting deteriorates
Solution Approach 1:
The patent creates a universal service list structure that serves multiple functions and platforms simultaneously. The same service list format can be used for both traditional broadcasting systems and IP-based networks, enabling a single receiver implementation to handle multiple service delivery methods. This multi-functional approach maintains the simplicity of automated service delivery while achieving comprehensive integration between traditional broadcasting and Internet-based services, providing a unified user experience across different platforms.
