Video Gallery Display Range Determination for Terminal Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in selecting videos from numerous options due to limited display space, making it complicated to find and choose videos that interest them, as they can't easily access videos outside the current selection screen.
Innovation Solution
A video distribution system that determines a transmission range for video gallery data based on the terminal device's display capabilities, generates a video gallery display screen with movable display ranges, and displays adjacent video data items partially to indicate their availability, allowing users to select more videos.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the number of displayed video items is increased to provide more options, then the user has more video choices, but the display space becomes insufficient and the interface becomes crowded
Solution Approach 1:
The patent extends the video gallery display from a two-dimensional screen view to a three-dimensional virtual space. Videos are arranged in a virtual gallery that can be navigated by panning and zooming operations, allowing users to access many more video items than would fit on a single screen without crowding the interface.
Solution Approach 2:
The patent implements a nested structure where a virtual gallery containing multiple video items is embedded within the terminal device's display interface. The video gallery display screen is transmitted from the video distribution device and contains a virtual space that nests additional video items beyond the immediate viewable area.
2Loss of information
If all video items are displayed at once to ensure complete visibility, then users can see all options, but the transmission data volume and processing load increase significantly
Solution Approach 1:
The patent pre-arranges video items in a virtual gallery structure on the video distribution device before transmission. The video gallery data including arrangement information is prepared in advance and transmitted to the terminal device, where the video gallery display screen is generated and displayed. This preliminary organization allows efficient transmission of only necessary display data rather than all video content simultaneously.
3Quantity of substance
If the video gallery display screen size is increased to show more videos, then more video items are visible, but the terminal device's display capabilities are exceeded
Solution Approach 1:
The patent creates a virtual three-dimensional gallery space that can be navigated through panning and zooming operations. This allows the system to present a large collection of video items without requiring a physically large display screen, as users can move through the virtual space to access different video items.
Solution Approach 2:
The patent implements dynamic navigation capabilities where the display range within the virtual gallery can be moved and adjusted. Users can pan across the gallery and zoom to access different video items, making the interface adaptable to various terminal display sizes while maintaining access to the full video collection.
Data Source
AI summary
A transmission range determination unit of a video distribution device receives information about a display position for a video gallery display screen from a terminal device and determines, according to the received information, a transmission range for video gallery data in which display images of video data items are arranged, to be a size greater than a possible display range of the terminal device. A video gallery display screen generation unit generates the video gallery display screen in which the display images of the video data items included in the transmission range determined by the transmission range determination unit are arranged according to an arrangement of the display images of the video data items which is defined by the video gallery data, wherein the video gallery display screen generation unit distributes the generated video gallery display screen to the terminal device.
