Directory Notification Unit for Digital Media Server Content Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing technologies face challenges in efficiently managing and transmitting large volumes of digital content across devices, particularly in scenarios where content changes occur after initial directory listing, leading to increased communication loads and user inconvenience.
Innovation Solution
An image processing apparatus that includes a reception unit for receiving transmission requests, a transmission unit for sending directory information, and a notification unit to inform display apparatuses of changes in stored content, allowing for the retransmission of updated directory information, including the creation of new directories when content is added, thus optimizing directory structure and reducing unnecessary data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all digital contents are transferred from DMS to DMP, then complete content delivery is achieved, but communication load increases significantly
Solution Approach 1:
The patent extracts and transmits only the necessary directory information and content metadata from the Digital Media Server to the Digital Media Player, rather than transferring all digital content data. This selective extraction reduces communication load while maintaining the ability to deliver complete content when needed.
Solution Approach 2:
The patent segments the content delivery process into multiple stages: first transmitting directory structure information, then transmitting content metadata, and finally transferring actual content data only when requested and needed. This segmentation allows the system to manage communication load efficiently while ensuring complete content delivery when required.
2Measurement precision
If directory listing is performed frequently to detect content changes, then content update detection is improved, but communication overhead increases
Solution Approach 1:
The patent implements a feedback mechanism where the Digital Media Server notifies the Digital Media Player of content changes proactively. When content is added, modified, or deleted on the server side, a change notification is sent to the player, eliminating the need for frequent directory listings and reducing communication overhead while maintaining accurate content change detection.
Solution Approach 2:
The patent performs preliminary actions by establishing a directory structure and content inventory on the server side before actual content transfer. The server maintains an updated record of all contents and their locations, allowing it to quickly notify players of changes without requiring players to repeatedly query for updates.
3Productivity
If hierarchical directory structure is classified and released, then navigation efficiency is improved, but system complexity increases
Solution Approach 1:
The patent implements a universal directory structure that serves multiple functions: it organizes content hierarchically for efficient navigation, provides metadata for content identification, and enables change notification mechanisms. This multi-functional directory system reduces overall system complexity by consolidating multiple roles into a single structured framework.
Data Source
AI summary
An image processing apparatus includes a reception unit configured to receive a transmission request of information on a directory for managing contents from a display apparatus, a transmission unit configured to transmit a response to the transmission request received by the reception unit, and a notification unit configured to notify the display apparatus of a change in a predetermined directory, thereby causing the display apparatus to transmit a transmission request of information on the predetermined directory again. When a new directory is formed on the same layer as that of the directory for managing the contents as a result of addition of the contents in the storage medium, the notification unit notifies the display apparatus of a change in a directory located on a layer above the directory for managing the contents.
