Ordered Multimedia Profile Groups for Seamless Quality Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The proliferation of OTT services has led to network overload due to varying bandwidth and quality of service, necessitating multiple multimedia content profiles, which complicates storage and management, and requires seamless transitions between profiles as distribution conditions change.
Innovation Solution
A method for digitally encoding multimedia content into ordered groups of profiles, where each profile and its successor satisfy continuity conditions regarding encoding parameters, allowing for flexible and imperceptible quality level changes during distribution, using a directed graph to form and select groups that meet specific quality and storage constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple encoding profiles are maintained to adapt to varying distribution conditions, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent segments the set of encoding profiles into multiple ordered groups, where each group contains profiles that satisfy specific continuity conditions. This segmentation allows the system to manage complexity by organizing profiles into structured subsets rather than handling all profiles uniformly, while maintaining adaptability through selective group usage based on distribution conditions.
2Adaptability or versatility
If multiple versions of multimedia content in different formats are stored, then adaptability is improved, but storage requirements increase
Solution Approach 1:
The patent creates ordered groups of profiles that can serve multiple distribution scenarios. Each group contains profiles that can adapt to different bandwidth and quality of service conditions, allowing a single grouped structure to handle multiple distribution formats and conditions without requiring separate complete versions for each scenario.
3Ease of operation
If seamless transitions between profiles are enabled, then user experience is improved, but device complexity increases
Solution Approach 1:
The patent pre-establishes ordered groups of profiles where continuity conditions are defined in advance between consecutive profiles within each group. This preliminary organization of profiles with predetermined continuity relationships allows seamless transitions during distribution without requiring complex real-time analysis, as the valid transition paths are already structured in the ordered groups.

AI summary
A method, implemented by computer means, for digitally encoding multimedia content into one or more video streams for on-demand distribution to at least one receiving terminal, the method comprising the following steps: from a given set of profiles, each profile being characterized by a value of at least one encoding parameter, forming one or more ordered groups of profiles, it being possible for a same profile to be present in multiple groups, such that in each group, each profile and its immediate successor satisfy a first predetermined condition, and selecting from the formed groups at least one group of profiles satisfying a second predetermined condition.
