IPTV Receiver Service Discovery via Segmented SI Decoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IPTV systems face challenges in efficiently searching for and managing IPTV services, as they lack effective methods for discovering and updating service information in a timely and accurate manner.
Innovation Solution
The method involves transmitting a service provider discovery record with registration server address information, allowing for registration and provision of EPG discovery information, enabling IPTV receivers to connect with service providers and update channel maps efficiently through a network interface, parsing service provider discovery records, and controlling registration requests based on read registration server address information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional IPTV systems are used, then basic broadcast content delivery is achieved, but efficient service discovery and information management is not possible
Solution Approach 1:
The system performs preliminary actions by automatically discovering service provider information, registration server addresses, and EPG data locations during the initial setup phase. The IPTV receiver proactively queries for service provider discovery records and registration information before actual service usage begins, establishing all necessary connection parameters and service maps in advance. This preliminary discovery and configuration process eliminates the need for manual service configuration and simplifies subsequent service management operations.
2Loss of time
If manual service configuration is used, then device complexity is reduced, but service information updates are slow and inaccurate
Solution Approach 1:
The system implements feedback mechanisms where the IPTV receiver continuously monitors for updates in service provider discovery records and EPG data. When updates are detected, the receiver automatically queries the registration servers for the latest service information, channel maps, and program guides. This feedback-driven update process ensures that service information is always current without requiring manual intervention, significantly reducing update time and improving accuracy while maintaining ease of operation through automation.
3Measurement precision
If comprehensive service information is collected, then service management accuracy is improved, but information processing complexity increases
Solution Approach 1:
The system segments service information collection into distinct, manageable components: service provider discovery records containing provider identification and contact information, registration server address information for authentication, and EPG discovery records for program guide data. Each segment is collected, parsed, and stored separately, allowing the IPTV receiver to process and manage this comprehensive information in an organized manner. This segmentation approach maintains high measurement precision for service information while reducing processing complexity through structured data organization.
Data Source
AI summary
AN IPTV receiver and a method of discovering an IPTV service are provided. A network interface transmits and receives an IP packet through a network. An IP network stack checks a destination of the received IP packet and classifies the IP packet according to a protocol. A Service Information (SI) decoder parses a service provider discovery record included in the IP packet to read registration server address information included in the service provider discovery record and parses a provision information record included in the IP packet to read EPG discovery information included in the provision information record. An IPTV Terminal Function (ITF) operation controller controls a request of a registration to be transmitted based on the read registration server address information controlling a request of a registration to be transmitted based on the read registration server address information for receiving the provision information record.
