Dynamic 3D Content Distribution via Video Component Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for 3D multimedia content poses challenges in balancing network bandwidth requirements with content quality, as existing networks need to transmit both 2D and 3D versions to cater to a mix of consumer devices, leading to significant bandwidth additions.
Innovation Solution
A method where a first video component representing a 2D image of multimedia content is sent to all client devices, and upon request, a second video component is added for 3D-enabled devices to combine and render 3D content, while 2D-enabled devices continue to consume only the first component, dynamically managing bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If both 2D and 3D versions of content are sent to all client devices, then all devices can be satisfied, but network bandwidth requirements increase significantly
Solution Approach 1:
The patent segments the 3D content into two separate video components (first video component and second video component). The first video component contains the base 2D video image that can be viewed by all devices, while the second video component contains additional depth information needed only for 3D viewing. This segmentation allows 2D devices to consume only the first component, while 3D devices receive both components, thereby reducing overall bandwidth requirements while maintaining compatibility with both device types.
2Quantity of substance
If only 2D version of content is sent, then bandwidth usage is reduced, but 3D-enabled devices cannot access 3D content
Solution Approach 1:
The patent implements a dynamic content delivery system where the network dynamically determines which video components to send based on the capabilities and requests of client devices. When a 3D-enabled device requests 3D content, the system dynamically adds the second video component to the transmission. This dynamic adaptation allows the system to optimize bandwidth usage for 2D-only scenarios while enabling 3D content delivery when needed, resolving the contradiction between bandwidth efficiency and 3D content availability.
3Adaptability or versatility
If 3D content is added to existing 2D content collection, then 3D-capable devices are served, but significant bandwidth additions are required
Solution Approach 1:
The first video component serves a universal function by being usable by both 2D and 3D devices. It contains the base video image that forms the foundation for both 2D playback and 3D rendering. The second video component serves the specialized function of providing additional depth information exclusively for 3D devices. This multi-functionality design ensures that the majority of content (first video component) can be shared across all devices, while only the specialized enhancement (second video component) requires additional bandwidth for 3D-capable devices.
Data Source
AI summary
Methods, apparatuses, and software are disclosed for sending only a first video component (e.g., data comprising one of a left or right component) of content to a plurality of client devices. Further aspects provide for sending, responsive to a request from one of the plurality of client devices, both the first video component and a second video component (e.g., data comprising both of the left and right components) to one or more of the plurality of client devices.
