Solution Overview
Problem
Current telecommunication systems face challenges in managing bandwidth efficiently, particularly for mobile devices, leading to high data consumption and degraded user experiences due to bandwidth limitations, which can be costly and require additional infrastructure investment.
Innovation Solution
The Content Optimization and Routing Architecture (CORA) technology manages bandwidth by employing content shaping strategies such as lossy or lossless transcoding, compression, and adaptive bit rate control, utilizing a mobile application and cloud-based infrastructure to optimize data transmission for individual devices, reducing data consumption while maintaining user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If content is streamed at high bit rate to maintain user experience, then quality of content delivery is improved, but bandwidth consumption increases
Solution Approach 1:
The system dynamically adjusts the bit rate of content delivery based on real-time network conditions and device capabilities. The service stack monitors bandwidth availability and modifies streaming parameters on-the-fly, transitioning between different quality levels to optimize both user experience and bandwidth utilization.
Solution Approach 2:
The invention changes key parameters such as bit rate, resolution, and frame rate of content streams based on network conditions. By modifying these parameters dynamically, the system delivers content at the highest possible quality that the current network can support, preventing both over-delivery (wasting bandwidth) and under-delivery (degrading UX).
2Quantity of substance
If network infrastructure is expanded to increase bandwidth capacity, then bandwidth availability is improved, but infrastructure cost and complexity increase
Solution Approach 1:
The system enables networks and devices to self-adjust content delivery parameters without requiring additional infrastructure. The service stack automatically monitors network conditions and adjusts streaming quality, allowing the existing infrastructure to serve variable demands without expansion.
Solution Approach 2:
The service stack provides multiple functions including content transcoding, quality adaptation, and network condition monitoring within a single software layer. This multi-functionality eliminates the need for separate specialized infrastructure components for each function.
3Quantity of substance
If content is processed with bandwidth reduction strategies to decrease data consumption, then bandwidth usage is reduced, but content quality and processing time increase
Solution Approach 1:
The system applies bandwidth reduction strategies selectively based on content type, device capabilities, and network conditions. Not all content is processed with the same level of compression - the system applies the minimum necessary processing to achieve acceptable quality while reducing bandwidth usage.
Solution Approach 2:
The service stack dynamically adjusts processing parameters such as compression level, resolution, and format based on real-time conditions. This allows the system to optimize the balance between bandwidth reduction and quality preservation for each specific content delivery scenario.
4Adaptability or versatility
If delay is introduced in communication channel to activate ABR capability, then adaptive bit rate control is enabled, but content delivery time increases
Solution Approach 1:
The service stack performs preliminary assessments of network conditions and device capabilities before initiating content delivery. By gathering this information in advance, the system can start streaming with appropriate parameters without requiring lengthy delays to determine ABR settings during playback.
Data Source
AI summary
Technologies are shown for content data transmission bandwidth management involving receiving content data for a mobile device, transmitting the content data at an initial bit rate, and introducing a delay in the communication channel to activate an adaptive bit rate (ABR) capability in the mobile device. The technologies can include receiving feedback pertaining to content data consumption in the mobile device and adjusting the delay in the communication channel to increase or decrease the bit rate of the ABR capability responsive to the feedback. The technologies can include determining an initial resolution of the content data during a trial period during transmitting content data to the mobile device and adjusting the delay in the communication channel to increase or decrease the bit rate of the ABR capability in the mobile device to a target bit rate.
