Hardware Evaluation of Multi-Scalable Video Transmission

In recent years, high-definition video content such as YouTube and Netflix has become an integral part of our lives, increasing the demand for wireless transmission of 4 K and 8 K images with high quality. Consequently, many technical papers have proposed systems for high-quality video transmission. However, most of these systems extend international standards, making implementation difficult. Therefore, in this paper, we construct a system compliant with IEEE 802.11ac/ax/be standards using a multi-scalable image transmission system. The multi-scalable image transmission system enables high-quality image transmission by structuring packets so that layers ordered by their contribution to image quality in JPEG 2000 can be sent to Sub STAs with larger channel capacities. By configuring the receiver using multiple Sub STAs, data with different contributions to image quality can be transmitted using the multi-user functionality of IEEE 802.11ac/ax/be standards. As a result, the MIMO system using multi-scalable image transmission can achieve high-quality communication without extending the IEEE 802.11ac/ax/be standards.
