IP Packet Burst Encapsulation for Multimedia Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multimedia content broadcasting over communication networks faces inefficiencies due to the lack of differentiation in IP packet processing, leading to increased delay and error correction challenges, particularly in radio broadcast networks where packet error rates are high, and existing solutions either consume excessive bandwidth or require complex and non-standardized error correction techniques.
Innovation Solution
A processor device is introduced to add information data to IP packets indicating start, end, and type of data sets, allowing for optimized encapsulation in bursts by analyzing this information to prioritize and manage IP packets, varying error correction levels, and adjusting burst sizes, thereby improving the efficiency of multimedia content transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If IP packets are encapsulated in bursts without differentiation based on content type, then the network infrastructure remains simple and standardized, but transmission delays increase and error correction becomes less effective
Solution Approach 1:
The patent applies local quality by differentiating IP packet processing based on content type information. The system identifies packet types (video, audio, data) and applies specific encapsulation and error correction strategies to each type, rather than treating all packets uniformly. This allows optimized error correction for video packets while maintaining simpler processing for other types.
Solution Approach 2:
The patent segments IP packets into different categories based on their content type (video, audio, data packets). This segmentation enables the system to manage each packet type separately with appropriate encapsulation and error correction, resolving the contradiction between simplified processing and effective error correction.
2Productivity
If error correction is applied to all IP packets uniformly, then the network infrastructure remains simple, but bandwidth consumption increases and transmission efficiency decreases
Solution Approach 1:
The system applies different error correction levels to different packet types based on their importance and error susceptibility. Video packets receive enhanced error correction since they are most susceptible to errors in radio broadcast networks, while audio and data packets receive lighter correction, optimizing bandwidth usage and transmission efficiency.
Solution Approach 2:
The patent applies partial error correction - not full correction to all packets, but selective correction based on packet type and error probability. This partial action reduces unnecessary bandwidth consumption while providing sufficient protection where needed.
3Loss of time
If IP packets are transmitted without content type information, then packet processing is simplified, but the ability to optimize burst composition and reduce delays is limited
Solution Approach 1:
The system performs preliminary identification of packet content types before encapsulation. By analyzing packet headers or payload markers in advance, the system categorizes packets and prepares appropriate encapsulation parameters, enabling optimized burst composition and reduced transmission delays without significant complexity increase.
Solution Approach 2:
The patent introduces minimal content type identification mechanisms that add only necessary information to packet headers or accompanying metadata. This localized quality enhancement provides the needed differentiation for optimized processing while keeping the overall system complexity low.
4Adaptability or versatility
If all IP packets are encapsulated in the same burst structure, then network infrastructure remains standardized, but the ability to prioritize critical data and optimize transmission is reduced
Solution Approach 1:
The patent implements dynamic burst composition where the encapsulation structure adapts to the specific packet types and content being transmitted. The system adjusts burst parameters such as error correction levels, packet ordering, and encapsulation formats based on real-time packet analysis, providing flexibility without requiring complete infrastructure redesign.
Solution Approach 2:
The system segments the encapsulation process into type-specific handling routines. Different packet types follow different encapsulation paths, allowing flexible burst composition while maintaining a standardized core infrastructure. This segmentation enables adaptability without proportionally increasing overall complexity.
Data Source
AI summary
IP encapsulation equipment encapsulates, into bursts, IP packets representing sets of multimedia data delivered by at least one multimedia content server. The bursts are accompanied beforehand by information data at least partly defining the set of data that is integrated into those IP packets and/or the content of which that set of data forms part, with a view to the broadcasting thereof to receiver equipments via a communication network. The information data added to the received IP packets is analyzed to instruct the encapsulation means to encapsulate at least some of those IP packets in selected positions in the bursts as a function of the corresponding information data. In this manner, all the IP packets including, the data of a set, are encapsulated in a single burst.
