Reception Apparatus NRT Content Access via External Network
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for storing and accessing non-real-time (NRT) content from digital television broadcast signals face challenges in efficiently managing content storage and retrieval, particularly when NRT content is not locally available, leading to inefficiencies in user access and potential memory constraints in devices like mobile devices.
Innovation Solution
A reception apparatus equipped with a receiver, memory, and processor that checks for local storage of NRT content and, if not found, determines if it can be downloaded from an external device via a communication network, allowing for seamless retrieval from either external devices or the broadcast signal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If NRT content is stored locally in the reception apparatus, then access speed is improved, but memory requirements increase
Solution Approach 1:
The system segments the content storage function across multiple locations: local memory in the reception apparatus and external devices accessible via communication network. This allows the system to store content in distributed locations rather than requiring all content to be stored locally, thereby reducing local memory requirements while maintaining access capability.
Solution Approach 2:
The system introduces an intermediary mechanism (processor) that manages content retrieval by checking local storage first and then accessing external devices via communication network when content is not locally available. This intermediary approach enables flexible content access without requiring all content to be pre-stored locally.
2Reliability
If the system checks local storage and then external devices, then content availability is improved, but system complexity increases
Solution Approach 1:
The system performs preliminary checking of local storage before attempting to access external devices. This preliminary action optimizes the access process by quickly determining whether content is locally available, avoiding unnecessary external device access operations, and only proceeding to external devices when truly necessary.
Solution Approach 2:
The reception apparatus autonomously manages its own content access needs by implementing a self-service mechanism that automatically checks local storage, determines availability, and accesses external devices when required. This self-service approach improves content availability without requiring complex external management systems.

AI summary
A method is provided for a reception apparatus to access non-real-time (NRT) content. The method includes receiving, by the reception apparatus, a selection of the NRT content included in a digital television broadcast signal broadcast by a content source. The reception apparatus determines whether the selected NRT content is stored in a memory of the reception apparatus. When the selected NRT content is determined not to be stored in the memory, the reception apparatus determines whether the selected NRT content can be downloaded from an external device that is accessible via a communication network. When the selected NRT content is determined to be downloadable from an external device that is accessible via the communication network, the reception apparatus downloads the selected NRT content from the external device.
