Information Search Server for Content Playback Progress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in searching for related information while content is being played back, as existing methods require suspending playback or interfere with the content display, especially when using a different terminal device.
Innovation Solution
An information search server system that manages user connections and acquires related information based on content playback progress status, allowing seamless retrieval and display on a separate terminal without interrupting playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the user searches for related information on the same screen as content playback, then the user can access information, but the display area interferes with the content being played back
Solution Approach 1:
The patent transitions from two-dimensional screen space by launching a virtual machine on a separate display device. This dimensional shift allows the search interface to exist in a different spatial dimension (separate physical device) rather than competing for screen real estate, thereby eliminating visual interference with the content playback while maintaining full information accessibility.
2Object-affected harmful factors
If the user uses a different terminal apparatus to search for information, then the content display is not interfered with, but the user must turn away from the content and operation becomes cumbersome
Solution Approach 1:
The patent introduces a virtual machine as an intermediary layer between the content playback system and the search interface. This virtual machine runs on a separate display device but maintains logical connection to the content playback apparatus through the virtual machine manager, enabling seamless information retrieval without requiring the user to physically turn away from the content or perform complex switching operations.
3Loss of information
If the user suspends playback to search for information, then the user can access related information, but the content playback is interrupted
Solution Approach 1:
The patent segments the information retrieval function from the content playback function by implementing a separate virtual machine environment. This segmentation allows the search operation to execute independently in the virtual machine while the main content playback continues uninterrupted in the host system, eliminating the need to suspend playback for information search.
4Productivity
If the user cannot temporarily stop content playback, then real-time searching is difficult, but suspending playback interrupts the content experience
Solution Approach 1:
The patent maintains continuous content playback operation while enabling simultaneous information search through the virtual machine. The virtual machine manager facilitates this continuity by allowing the search operation to proceed independently without affecting the main playback thread, thus achieving real-time information access without interrupting or requiring suspension of content playback.
Data Source
AI summary
In an information search server 600, a database includes a table storing a progress status of content, and information related to the content at the progress status, and a table storing user information with respect to a content playback apparatus, an identifier of the content playback apparatus, and an identifier of a terminal apparatus that differs from the content playback apparatus. A connecting user management unit manages user information with respect to the content playback apparatus connected to the information search server. A related information acquisition unit acquires a current progress status of content being played back on the content playback apparatus, and acquires information related to the content at the current progress status. A connecting user management unit identifies a terminal apparatus that differs from the content playback apparatus, and the related information acquisition unit transmits the related information to the terminal apparatus.
