MDDI Enhanced Reverse Link Encapsulation Packet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Mobile Display Digital Interface (MDDI) systems require redundant field transmissions for data transfer, including a round trip delay measurement packet and a separate reverse encapsulation packet, which increases complexity and power consumption.
Innovation Solution
The enhanced reverse link encapsulation packet combines the features of a round trip delay packet with a reverse encapsulation packet, eliminating the need for a maximum reverse byte indicator by using the packet length field to define the maximum data transmission length and indicating completion with a '0' value, thereby simplifying data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate round trip delay measurement packet and reverse encapsulation packet are transmitted, then measurement accuracy is improved, but device complexity increases
Solution Approach 1:
The patent combines the round trip delay measurement functionality with the reverse encapsulation packet into a single integrated packet structure. The reverse encapsulation packet simultaneously carries data from the client to the host and includes timing information for round trip delay measurement, eliminating the need for separate measurement packets and reducing overall system complexity while maintaining measurement accuracy
2Productivity
If maximum reverse byte indicator is transmitted separately, then data transfer control is improved, but use of energy increases
Solution Approach 1:
The patent integrates the maximum reverse byte indicator into the reverse encapsulation packet itself, combining multiple control functions into a single transmission. The packet simultaneously conveys data, timing information for delay measurement, and the maximum reverse byte indicator, thereby reducing the number of separate transmissions and lowering power consumption while maintaining effective data transfer control
3Use of energy by moving object
If redundant field transmissions are eliminated, then use of energy decreases, but loss of information increases
Solution Approach 1:
The reverse encapsulation packet is designed as a multi-functional structure that simultaneously performs multiple roles: data transmission from client to host, round trip delay measurement, and maximum reverse byte indicator conveyance. This universal packet design eliminates redundant transmissions and reduces power consumption while ensuring all necessary information is preserved through careful integration of multiple functions into a single comprehensive packet structure

AI summary
An Enhanced Reverse Link Encapsulation packet for a MDDI system combines and improves upon the functionality of the Round Trip Delay Measurement packet and Reverse Encapsulation packet. The combination of these packets allows for reduced MDDI link overhead when providing client reverse link transmission. This packet allows for dynamic reverse link bandwidth allocation and therefore improved MDDI link utilization.
