Uncompressed video transmission in portable devices for wireless video mirroring service

Wireless transmission of uncompressed video guarantees higher quality with lower latency than compressed video transmission. Although current wireless technologies cannot fully cover required data rates of about a few Gb/s for full high definition resolution, some wireless technologies such as ultra-wideband (UWB) provide 1 Gb/s data rate which is adequate for uncompressed video transmission in portable devices. In this paper, we propose an uncompressed video transmission system for wireless mirroring services in potable devices. We firstly simulated the performance of uncompressed video transmission using 1 Gb/s UWB technology. Then we implemented hardware-based uncompressed video processing block and Gb/s wireless MAC accelerator. Finally, we show the possibilities of uncompressed video transmission using single 1 Gb/s UWB physical layer (PHY) and extended transmission for more higher resolution using multiple UWB PHYs.
