Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies lack flexibility in determining the encoding mode for media data transmission, as the mode is set based on a standard protocol and does not adapt to changes in frequency bands, leading to inefficient data transmission.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If compression mode is used for media data transmission in all frequency bands, then data transmission reliability is improved, but device complexity and energy consumption increase due to continuous compression and decompression operations
Solution Approach 1:
The patent changes the encoding parameter (compression level) based on the frequency band parameter. In high-frequency bands (60GHz, 5GHz) with high transmission rates, the system uses non-compression or low-compression modes. In low-frequency bands (2.4GHz) with lower transmission rates, the system uses compression mode. This dynamic parameter adjustment resolves the contradiction by adapting compression levels to network conditions, ensuring reliability where needed while reducing complexity where bandwidth is sufficient.
2Device complexity
If non-compression mode is used for media data transmission, then device complexity and energy consumption are reduced, but data transmission efficiency deteriorates in low-frequency bands with limited bandwidth
Solution Approach 1:
The system dynamically changes the compression parameter based on frequency band conditions. In low-frequency bands (2.4GHz) with limited bandwidth, compression is applied to increase transmission efficiency. In high-frequency bands (60GHz, 5GHz) with abundant bandwidth, non-compression mode is used to reduce device complexity and energy consumption. This conditional parameter adjustment resolves the contradiction by optimizing the right side of the trade-off in each scenario.
3Stability of the object's composition
If encoding mode is determined by standard protocol during initial network access, then system stability is improved, but adaptability deteriorates as the mode cannot change when switching to different wireless networks
Solution Approach 1:
The patent transforms the static encoding mode determination into a dynamic process. The system initially determines the encoding mode based on the standard protocol during network access, providing stability. However, it continuously monitors frequency band changes and dynamically adjusts the encoding mode when switching between different wireless networks (2.4GHz, 5GHz, 60GHz), thereby achieving both stability and adaptability.
Solution Approach 2:
The system implements a feedback mechanism where the encoding mode is initially set by the standard protocol, then continuously monitored against actual frequency band conditions. When the system detects a frequency band change, it provides feedback to adjust the encoding mode accordingly, ensuring adaptability while maintaining the initial stability provided by the standard protocol.

AI summary
A method and a device for transmitting media data are provided, where a device sending the media data and a device receiving the media data are currently located in a same wireless network, and the method includes: acquiring, by the sending device, a frequency band of the wireless network; determining, by the sending device, whether the frequency band of the wireless network is a set frequency band; and if yes, setting a media data encoding mode of the sending device to non-compression, and sending, by the sending device, media data that is not compressed to the receiving device; or if the frequency band of the wireless network is not the set frequency band, setting a media data encoding mode of the sending device to compression, and sending, by the sending device, media data that is compressed to the receiving device. This solution reduces a delay caused by compression, reduces resources consumed by the sending device for data compression.
