Adaptive Data Layer Distribution for Mobile Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of mobile devices often struggle to capture high-quality content due to location limitations or device constraints, and they face difficulties in accessing higher quality content captured by nearby devices.
Innovation Solution
A system and method for data distribution over a network, where a device can capture content and publish it for other devices to access. The publishing device creates data layers based on the viewing parameters of requesting devices, using adaptive/multiple bit rate streaming and scalable video coding, to ensure optimal content quality and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a device captures content at high quality, then content quality is improved, but device complexity and energy consumption increase
Solution Approach 1:
The patent segments the content distribution system into multiple data layers (base layer and enhancement layers). The base layer provides minimum quality content that can be decoded by all devices, while enhancement layers provide additional quality improvements. This segmentation allows high-quality content capture without requiring every device to have high-end capabilities, as the system distributes differentiated layers based on device capabilities.
Solution Approach 2:
The patent changes the parameter of content delivery by creating multiple versions or layers of the same content with different quality levels. Instead of delivering a single high-quality version that all devices must handle, the system transforms the content into parameterized layers that can be selectively received and decoded based on each device's capabilities, thus resolving the contradiction between quality and device complexity.
2Adaptability or versatility
If content is distributed to multiple devices with different capabilities, then content accessibility is improved, but data transmission complexity increases
Solution Approach 1:
The patent segments content into a base layer accessible by all devices and enhancement layers for devices with higher capabilities. This segmentation enables broad accessibility while simplifying transmission, as the base layer can be distributed to all devices uniformly, and enhancement layers are only transmitted to capable devices, reducing overall transmission complexity.
Solution Approach 2:
The base layer serves as a universal component that can be decoded by any device regardless of capability, providing multi-functionality. This universal base layer simplifies the distribution architecture by establishing a common foundation that all devices can access, while enhancement layers provide additional functionality only where needed, thus improving accessibility without proportionally increasing transmission complexity.
3Manufacturing precision
If multiple data layers are transmitted to satisfy different viewing parameters, then content quality匹配 is improved, but network bandwidth consumption increases
Solution Approach 1:
The patent segments content into hierarchical layers where the base layer provides essential quality and enhancement layers provide incremental improvements. This segmentation optimizes bandwidth consumption by allowing receivers to selectively decode only the layers their capabilities permit, rather than transmitting and requiring reception of all data at maximum quality for every device.
Solution Approach 2:
The patent applies local quality by delivering different quality levels to different devices based on their specific capabilities. Each device receives and decodes the appropriate layer(s) for its viewing parameters, ensuring optimal quality-match without wasting bandwidth transmitting excessive quality to devices that cannot utilize it, thus resolving the contradiction between quality-matching and bandwidth consumption.

AI summary
Provided are methods and systems for data distribution over a network. A device can capture content. The device can be configured to publish the content so that other devices in a network can access the content. The publishing device can indicate to other devices on the network that the content is available for use. In response, the publishing device can receive requests for the content from the other devices. When sending a request, a requesting device can include viewing parameters that indicate capabilities of the requesting device. The publishing device can create one or more data layers that comprise the content based on the viewing parameters of requesting devices. The publishing device can also determine a transmission path to the various requesting devices and transmit the one or more data layers along the transmission path.
