Scalable Data Transmission via Segmented Packet Headers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face inefficiencies in transmitting scalable data, where basic information and complementary information are not optimally adapted for different receivers, leading to suboptimal quality and resource wastage.
Innovation Solution
A method for transmitting basic information and packets of complementary information, where the packets contain a field detailing how the complementary information enhances the quality of the basic information, allowing for independent reading and adaptation based on receiver needs, without requiring separate requests for each.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If basic information and complementing information are transmitted together to all receivers, then all receivers can achieve maximum quality, but transmission resources are wasted on receivers that do not need or cannot process the complementing information
Solution Approach 1:
The information is segmented into basic information and complementing information, where basic information is transmitted to all receivers and complementing information is selectively transmitted only to receivers that need or can process it. This segmentation resolves the contradiction by ensuring all receivers get the essential quality baseline while avoiding waste of transmission resources on receivers that cannot utilize the additional complementing information.
2Productivity
If complementing information is transmitted without specific requests from receivers, then transmission overhead is reduced, but receivers cannot adapt the quality to their specific needs
Solution Approach 1:
Receivers declare their capability to process complementing information in advance, before the actual transmission occurs. This preliminary action allows the transmitter to proactively send complementing information to capable receivers without waiting for specific requests, thereby maintaining high transmission efficiency while ensuring adaptability to receiver needs.
3Device complexity
If receivers decode only basic information, then processing complexity is reduced, but quality is limited
Solution Approach 1:
The receiver's processing capability is made dynamic through the capability declaration mechanism. Receivers can dynamically adjust their behavior by declaring whether they can process complementing information. This allows the system to adapt to each receiver's processing capabilities, enabling simple receivers to decode only basic information while complex receivers can decode both basic and complementing information for higher quality.
4Adaptability or versatility
If packet structure includes fields that can be read independently of complementing information, then receivers can make informed decisions about decoding, but packet structure complexity increases
Solution Approach 1:
The packet structure is segmented into a header portion containing readable fields and a payload portion containing the complementing information. The header fields can be read and processed independently to enable receiver decision-making, while the complementing information is only fully processed by receivers that have declared capability. This segmentation reduces the effective complexity for simple receivers while maintaining adaptability.
Data Source
AI summary
ANS method for transmitting data, in which basic data is transmitted while one or several packets are transmitted with data that complements the basic data and increases the quality of the basic data when being decoded by a receiver. The packets contain at least one field with information about how the complementing data of the respective packet increases the quality of the basic data. The field can be read independently of the complementing data of the respective packet. Based on the information, a decision can be made as to whether the packets are to be forwarded or decoded.
