Multi-Window Preview for PVR Content Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in recognizing the overall contents of recorded material at a glance and efficiently locating specific playback positions in contemporary display devices, as they rely on limited preview modes and require extensive navigation to find desired content.
Innovation Solution
A method and apparatus that display a list of recording items with multiple sample images via multiple preview windows, allowing users to simultaneously view thumbnails or sample images corresponding to selected items, along with time information, facilitating quick recognition and selection of playback positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single preview window is used to display sample images of recording items, then the device complexity is reduced, but the user recognition of overall contents of recorded material deteriorates
Solution Approach 1:
The single preview window is segmented into multiple sub-preview windows arranged in a grid pattern. Each sub-preview window displays a different sample image (thumbnail) of the selected recording item, allowing users to view multiple contents simultaneously without increasing overall device complexity.
Solution Approach 2:
The preview display transitions from a single-dimensional (one window) to a multi-dimensional (multiple windows in spatial arrangement) structure. This dimensional expansion allows more information to be presented within the same screen real estate, improving content recognition without adding physical hardware complexity.
2Device complexity
If a revolving display of thumbnails is used in a single preview window, then the device complexity is minimized, but the time required for user recognition of specific recording positions increases
Solution Approach 1:
Multiple sample images are pre-loaded and simultaneously displayed in the grid of sub-preview windows before the user makes a selection. This eliminates the need for sequential revolving display, allowing users to immediately identify desired content without waiting for thumbnails to rotate through the display.
Solution Approach 2:
Instead of displaying one thumbnail at a time (partial action), the system displays multiple thumbnails simultaneously (excessive action). This provides users with more visual information at once, enabling faster recognition and selection of desired recording positions.
3Loss of information
If multiple preview windows are used to display multiple sample images simultaneously, then the user recognition of recorded material contents is improved, but the device complexity increases
Solution Approach 1:
The multiple sub-preview windows within the preview area serve a universal function: displaying sample images of the selected recording item. This multi-functional display structure allows the system to present multiple pieces of information (different thumbnails) using a unified interface design, managing complexity through functional integration.

AI summary
A method of displaying a recorded material and display device using the same facilitates user recognition of the content of selected recorded material prior to its reproduction. The display device includes a personal video recorder for storing content of at least one recording item of a recording item list; a PVR controller (104) for extracting a plurality of thumbnails corresponding to each stored recorded item, each thumbnails being extracted in correspondence to a prescribed time interval; and a display module (106) for displaying the recording item list in response to a recording item list request and for simultaneously displaying, in response to a user selection of a specific recording item, the extracted thumbnails corresponding to the selected recording item via a corresponding plurality of preview windows. A specific preview window is designated, and the selected recording item is reproduced from a recording position corresponding to the thumbnail of the designated window.
