Dynamic Bitrate Allocation for Regions of Interest in Bandwidth Constrained Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In bandwidth-constrained environments, providing high-quality content such as video, audio, and images is challenging due to limited bandwidth, often requiring compromises in bitrate, resolution, or frame rate, which affect user experience and are not cost-efficiently addressed by increasing bandwidth.
Innovation Solution
A method and processing unit that identifies regions of interest within content based on user interactions, such as head or eyeball movement, and uses Natural Language Processing to derive context from audio inputs, modifying bitrate only for those regions of interest to maintain content quality without additional bandwidth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If bandwidth is increased to provide high-quality content, then content quality is improved, but cost efficiency deteriorates
Solution Approach 1:
The patent applies local quality by differentiating content rendering quality across different spatial regions. Regions of interest (ROI) are identified based on user actions such as head movement and eyeball movement, and these regions are rendered at higher bitrate and quality. Non-ROI regions are rendered at lower bitrate. This allows high-quality content delivery focused on areas the user actually observes, improving perceived quality without proportionally increasing overall bandwidth consumption.
2Quantity of substance
If bitrate is reduced to accommodate bandwidth constraints, then bandwidth requirements are met, but user experience deteriorates
Solution Approach 1:
The system maintains user experience by ensuring that regions of interest - where the user is actually looking or attending - are rendered at high quality with sufficient bitrate. By dynamically identifying ROI based on user actions (head movement, eyeball movement, audio inputs) and allocating higher bitrate to these regions, the system preserves critical visual quality where it matters most to user experience, while reducing bitrate in non-critical regions to meet bandwidth constraints.
Solution Approach 2:
The patent employs dynamic adaptation by continuously tracking user actions and adjusting the regions of interest and corresponding bitrate allocation in real-time. As users move their heads or eyes, or as audio inputs indicate changing attention, the ROI regions are updated and bitrate is dynamically reallocated. This dynamic approach ensures that bandwidth is consistently directed toward maintaining quality in the currently relevant portions of the content, preserving user experience under bandwidth constraints.
3Reliability
If uniform quality is maintained across all content regions, then user experience is consistent, but bandwidth consumption increases
Solution Approach 1:
The patent explicitly rejects uniform quality across all regions in favor of localized quality differentiation. Instead of maintaining consistent bitrate throughout the entire content, the system identifies specific regions of interest and applies higher quality rendering only to those areas. This allows the system to meet bandwidth constraints by reducing overall bandwidth consumption while maintaining high quality where users are actually observing, rather than wasting bandwidth on regions users are not viewing.
Solution Approach 2:
The content is segmented into regions of interest and non-regions of interest based on user actions. This segmentation allows differential bitrate allocation - high bitrate for ROI regions and low bitrate for non-ROI regions. By dividing the content space into these functional segments, the system optimizes bandwidth usage by concentrating quality resources on important regions while reducing resources on less important regions, achieving overall bandwidth efficiency without sacrificing user experience in critical areas.

AI summary
A method and processing unit for providing content in a bandwidth constrained environment is disclosed. Initially, a content along with audio inputs, which is received during rendering of the content and provided to one or more users in a bandwidth constrained environment is received. Further, at least one object of interest within the content and associated with the audio inputs is identified. One or more regions of interest, including the at least one object of interest, is determined in the bandwidth constrained environment. Upon determining the one or more regions of interest, bitrate for rendering the content is modified based on the determined one or more regions of interest, to obtain a modified content for the bandwidth constrained environment. The modified content is provided to be rendered in the bandwidth constrained environment.
