Hello everybody! This post describes how Transport Stream dataflow within the Joker TV universal USB DTV receiver. All described functionalities are written on Verilog and run on Altera FPGA (EP4CE22F17C8N). The firmware is fully open source and can be found here. I have also prepared the following diagram for a better understanding: As you can […]
Hello everybody, this post describes data transfer over USB from Joker TV to a host using high bandwidth USB isochronous transfers which has bitrate 3 times higher than regular USB isochronous transfers. High bandwidth USB isochronous transfers Regular isochronous USB transfer contains only one data packet (DATA_0) per microframe (125 usec) and can achieve 62.5 Mbit/sec […]
