Adaptive Data Transmission with Importance-Based Dropping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multimedia transmission techniques, such as MPEG-2 TS, face inefficiencies and overhead due to unidirectional communication and fixed frame sizes, particularly in network congestion scenarios, necessitating a more adaptive and efficient method for transmitting hybrid content in heterogeneous networks.
Innovation Solution
The proposed method determines which data pieces to drop based on importance information, generates an incomplete data indicator, and transmits only the essential data pieces, allowing the receiving entity to decode the remaining data without waiting for omitted parts, thereby efficiently managing resources during network congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional MPEG-2 TS transmission is used, then transmission protocol compatibility is maintained, but transmission efficiency deteriorates due to unidirectional communication and fixed frame size
Solution Approach 1:
The patent implements dynamic frame size adjustment and bidirectional communication mechanisms in the MMT protocol, allowing the transmission system to adapt frame parameters based on network conditions and content requirements, thereby improving transmission efficiency while maintaining protocol manageability through standardized dynamic adjustment procedures
2Productivity
If complete data transmission is maintained during network congestion, then data completeness is preserved, but resource utilization deteriorates due to unnecessary overhead
Solution Approach 1:
The patent segments data into prioritized segments with different importance levels, allowing the transmission system to selectively transmit only essential segments during network congestion. The receiver can then reconstruct the complete data by assembling transmitted segments, maintaining data completeness while improving resource utilization by avoiding transmission of non-essential segments during congested conditions
Solution Approach 2:
The patent implements dynamic parameter adjustment including variable data rate modulation and adaptive segmentation based on network conditions. During congestion, the system changes transmission parameters to prioritize critical data segments while reducing or omitting less important segments, thereby optimizing resource utilization without compromising essential data completeness
3Adaptability or versatility
If fixed frame size transmission is used, then transmission simplicity is maintained, but adaptability deteriorates in heterogeneous networks
Solution Approach 1:
The patent implements dynamic frame size adjustment and adaptive transmission parameters that can change based on network conditions and content requirements. The MMT protocol allows flexible configuration of transmission parameters including frame size, data rate, and segmentation strategies, enabling the system to adapt to heterogeneous networks while maintaining manageable complexity through standardized adaptive mechanisms

AI summary
The method for transmitting data in a communication system provided by one embodiment of the present disclosure comprises the steps of: determining a data piece which is not to be transmitted, in view of importance information on respective data pieces constituting a data unit to be transmitted; generating an incomplete data indicator indicating that at least one data piece is not transmitted among all of the data pieces constituting the data unit; and transmitting the incomplete data indicator and the data pieces other than the data piece which has been determined not to be transmitted.
