GT4K-4201/4204 provides high-quality 4K video encoding and decoding transmission solutions for professional video applications such as broadcasting and medical imaging. Based on FPGA hardware acceleration, the CODEC is compatible with H.265/H.264, also supports NDI High Bandwidth and NDI HX|HX3. Single channel 4Kp60 or quad 1080p60 stream can be transmitted with 4:2:2 10 bit HDR broadcast quality. And ultra-low latency mode provides end-to-end 2-3 frames stable delay for SRT A/V transmission. Even in harsh network environments, stable transmission with controllable bit rate jitter can be achieved to provide high-quality videos at ultra-low latency and with very low bandwidth consumption. The product adopts a 1/2 U standard rack and provides professional interfaces including bi-direct 12G-SDI, HDMI 2.0, Genlock, and dual gigabit Ethernet. It can also expand ST2110 IP and DVB-ASI interface to create a bridge between IP infrastructure and standard DVB.
