Broadcast Receiver NRT Service Guide Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional broadcast receivers are unable to receive and process non-real time (NRT) services, limiting their ability to provide users with a comprehensive range of services that include both real-time (RT) and NRT content.
Innovation Solution
A method and broadcast receiver configuration that enables the reception, storage, and processing of NRT services by utilizing signaling information tables to create a non-real time service guide, allowing users to shift between RT and NRT service guides, and perform playback or download scheduling functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional broadcast receivers only support real-time services, then the device complexity remains low, but the service versatility is limited
Solution Approach 1:
The broadcast receiver is designed to handle both real-time and non-real time services through a unified service guide interface. The service guide manager dynamically determines whether to display RT-SGS or NRT-SGS based on user input, allowing the same device to provide multiple service types without requiring separate dedicated systems for each service mode.
Solution Approach 2:
The service guide display mode dynamically switches between real-time and non-real time service guides based on user interaction. When users input past time information, the system transitions to NRT-SGS; when current or future time is input, it displays RT-SGS. This dynamic adaptation allows the system to respond to different user needs without fixed configuration.
2Ease of operation
If a unified service guide interface is used for both RT and NRT services, then the ease of operation improves, but the information precision may be compromised
Solution Approach 1:
The service guide interface applies different display qualities and information structures to different service types. The RT-SGS displays real-time program information with time-based navigation, while the NRT-SGS displays archived content with different organizational structures. Each service guide type is optimized for its specific purpose, providing locally appropriate information precision while maintaining a unified overall interface.
Solution Approach 2:
The service guide manager dynamically adjusts the display content and structure based on the selected service type. The system transitions between different information presentation modes depending on whether RT or NRT service is selected, ensuring that the most relevant and precise information is displayed for each service context without requiring separate interfaces.
3Measurement precision
If separate service guides are maintained for RT and NRT services, then the information precision is maintained, but the device complexity increases
Solution Approach 1:
The patent merges the functionality of separate RT and NRT service guides into a unified service guide interface managed by a single service guide manager. This manager handles both service types, dynamically switching between them based on user input, thereby maintaining information precision for both service types while avoiding the complexity of completely separate guide systems.
Solution Approach 2:
The service guide manager is designed as a universal component that can handle both real-time and non-real time service guide operations. This multi-functional approach allows the system to maintain distinct information structures for RT and NRT services while using a single management entity, reducing overall system complexity compared to having entirely separate management systems.
4Adaptability or versatility
If the service guide dynamically switches between RT and NRT modes, then the adaptability improves, but the loss of time for mode switching may increase
Solution Approach 1:
The service guide manager maintains readiness to switch between RT and NRT service guide modes by pre-loading and organizing both types of service guide data structures. When user input indicates a mode change is needed, the transition can occur rapidly because the necessary data structures and management logic are already prepared, minimizing the time loss associated with mode switching.

AI summary
A method of processing a non-real time service of a broadcast receiver, which receives and processes a service being transmitted in non-real time, and a broadcast receiver are disclosed. Herein, the method of processing a non-real time service of a broadcast receiver includes receiving a signaling information table including additional information on contents configuring a non-real time service and a content identifier for each content, acquiring and storing the additional information on contents and the content identifier for each content from the signaling information table, when a non-real time specific service guide is requested from a real-time specific service guide screen, configuring the non-real time specific service guide based upon the stored additional information and content identifier of the stored contents, thereby displaying a non-real time specific service guide screen, and performing a playback or download scheduling function on the content selected from the non-real time specific service guide screen.
