Abstract: There is an increasing demand for interactive industrial display applications with wireless connectivity. This requires low latency, real-time data transmission and high reliability. In general, these two requirements, low latency and high reliability, are contradictory. We will present a reliable, low-latency wireless video transfer system that uses the WiFi standard (IEEE 802.11) for data transfer. The sending device is Cyclone V SoC based and the display is a commercial tablet computer (iPad). In the Cyclone V FPGA, the video data is compressed and encoded using a low latency optimised Forward Error Correction (FEC) scheme. The ARM Cortex A9 processor of the SoC device controls the wireless module, the compression block in the FPGA as well as the data transfer over WiFi. We will discuss the challenges of low-latency compression, WiFi data transfer on a SoC and video decompression on a tablet computer in the GPU.
