Broadcast Receiver NRT Service Management via Service Manager
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 a variety of services to users compared to conventional receivers.
Innovation Solution
A method and broadcast receiver that include a tuner and service manager to receive and process NRT services by storing contents downloaded through FLUTE or the internet, displaying a list of recordings with detailed information, and managing storage space for operator and user contents, with features like user preference settings and protection options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional broadcast receivers are used, then device simplicity is maintained, but service variety and NRT service capability are limited
Solution Approach 1:
The broadcast receiver is designed to perform multiple functions by integrating both real-time service reception and non-real time service processing capabilities. The service manager component enables the receiver to handle diverse service types (NRT and RT) through a unified architecture, allowing single device to provide multiple services without requiring separate dedicated receivers for each service type.
Solution Approach 2:
The receiver architecture is segmented into distinct functional modules including tuner, service manager, and storage medium. The service manager is further divided into sub-components for NRT service processing and RT service processing. This segmentation allows each module to specialize in specific tasks while maintaining overall system versatility, resolving the contradiction between complexity and adaptability.
2Adaptability or versatility
If NRT services are added to broadcast receiver, then service variety is improved, but processing complexity increases
Solution Approach 1:
The service manager acts as an intermediary component between the tuner and storage medium, specifically introducing an NRT service processing sub-module that mediates the complex NRT service operations. This intermediary layer handles the complexity of NRT service processing (including file delivery, metadata management, and content storage) independently, preventing processing complexity from propagating through the entire system and making NRT service integration manageable.
3Ease of operation
If storage medium is used for NRT services, then content management capability is improved, but storage space requirements increase
Solution Approach 1:
The system performs preliminary actions by pre-allocating storage spaces for different content types (NRT content and RT content) and pre-processing metadata during content delivery. The service manager prepares content for storage by organizing files and metadata in advance, and pre-allocates storage regions based on expected content sizes. This preliminary organization reduces the need for excessive storage space by optimizing storage efficiency from the outset.
Solution Approach 2:
The storage medium is organized with different storage spaces allocated for different types of content with different quality requirements. NRT content receives dedicated storage space with specific organization structures, while RT content has separate allocation. This local quality differentiation optimizes storage space usage by applying appropriate storage strategies to each content type rather than using a uniform approach, thereby improving content management capability without proportionally increasing total storage requirements.

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 the additional information on contents and the content identifier for each content from the signaling information table, storing contents being downloaded through a FLUTE or an internet in a storage medium, based upon the additional information on contents and the content identifier for each content, and displaying a list of recordings including the contents stored in the storage medium, wherein a list of recordings screen displaying the list of recordings includes at least one of a content name, a channel name, a date of recording, and a content size.
