Multimedia Packet Structure for Independent Decoding Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Moving Picture Experts Group (MPEG) media transport (MMT) technology lacks detailed schemes for configuring packets, which affects decoding efficiency and speed in multimedia communication systems.
Innovation Solution
The proposed solution involves generating and transmitting packets with at least two data units that are decodable independently, where one unit includes control information, and the receiving device can fragment and reassemble these units to determine completeness and store control information appropriately, enhancing decoding efficiency and speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a packet is configured with multiple data units for independent decoding, then decoding efficiency and speed are improved, but packet structure complexity increases
Solution Approach 1:
The packet is divided into multiple independently decodable data units, where each unit contains a complete set of syntax elements required for decoding. This segmentation allows the receiver to decode and display portions of the media content independently without waiting for the entire packet, thereby improving decoding efficiency and speed while managing structural complexity through standardized unit design
2Adaptability or versatility
If control information is embedded within data units, then packet flexibility and adaptability are improved, but information organization complexity increases
Solution Approach 1:
Control information (syntax elements) is merged directly within each data unit structure, allowing each unit to be self-contained and independently processable. This merging approach enables flexible packet formats that can adapt to different media characteristics while maintaining organized information structure through consistent syntax element placement within each unit
