HMD Communication Apparatus Bandwidth Multiplexation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Head-Mounted Display (HMD) systems face bandwidth limitations when transmitting both video and communication data, leading to a decrease in video quality due to reduced bit rates or data amounts.
Innovation Solution
The system employs a communication apparatus with an obtaining means for identifying effective and non-effective intervals in video data input, a setting means to determine the multiplexation method for video and communication data based on these intervals, and a transmission means to efficiently transmit multiplexed data, optimizing bandwidth usage by adjusting data widths accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If video data and communication data are transmitted simultaneously over a limited bandwidth channel, then both types of data can be transmitted, but the video quality decreases due to reduced bit rates
Solution Approach 1:
The transmission channel is segmented into multiple data widths (first data width for video, second data width for communication data). The system divides the bandwidth allocation dynamically, assigning different portions of the total bandwidth to video and communication data based on current transmission needs, thereby preventing video quality degradation while ensuring communication data transmission.
Solution Approach 2:
The data width allocation is made dynamic rather than fixed. The system determines whether to use the first data width (prioritizing video) or second data width (prioritizing communication data) based on real-time conditions. This dynamic adjustment allows the system to adapt to varying bandwidth availability and data priorities, resolving the contradiction between transmitting both data types and maintaining video quality.
2Manufacturing precision
If the data width for video transmission is increased to maintain video quality, then video quality is preserved, but the bandwidth available for communication data transmission is reduced
Solution Approach 1:
The system changes the parameter of data width dynamically. By switching between the first data width (larger, for video priority) and second data width (smaller, for communication priority), the system can adjust the balance between video quality and communication data transmission volume based on current requirements, resolving the trade-off between these two parameters.
3Device complexity
If a fixed data width is used for transmission, then the transmission system is simple, but it cannot efficiently utilize variable bandwidth availability
Solution Approach 1:
The transmission system uses dynamic data width determination instead of a fixed data width. The bandwidth determination unit selects between the first and second data widths based on current bandwidth availability and data priorities, enabling efficient bandwidth utilization while maintaining manageable system complexity through a structured decision-making process.

AI summary
A communication apparatus includes at least one processor executing instructions to operate as an obtaining unit to obtain first video data including repetition of an effective interval in which frame image data of a first video is input and an interval in which image data is not input, second video data comprising repetition of an effective interval in which frame image data of a second video is input and an interval in which frame image data is not input, and communication data other than the video data. Instructions are also executed to operate as a setting unit to set a method of multiplexation of the first video data, the second video data, and the communication data in accordance with the effective interval of the first video data and the effective interval of the second video data, and a transmission unit to transmit data multiplexed in accordance with the set method of multiplexation.
