Q: How to stop the probe correctly if it has been started as the console application?.Q: How can I start the probe as console application?.Q: How shall I start working with the monitoring system?.Differences and Restrictions of Linux and Windows versions.I’m open to discuss any proposals where possible. Joker TV is based on FPGA and has “endless” possibilities to implement any required functionality for TS processing. Stream #0:2(spa): Audio: ac3 ( / 0x0081), 48000 Hz, stereo, fltp, 192 kb/sĪs you can see out.ts file contains only one program with one video PID 0x31 and two audio PID’s – 0x34 (English) and 0x35 (Spanish). This command is tuned to 575MHz ATSC (broadcasts NBC channel in Miami, FL) and save TS only for programs with the number 3. Transport Stream PID filtering exampleĮxample, of Transport Stream PID filtering usage (you can pass multiple –program arguments to choose more than one program): $ joker-tv -d 11 -f 575000000 -b 6000000 -m 7 -program 3 I have described this in a separate post here. In the final stage, TS is passed back to host using USB isochronous transfers. Then filtered Transport Stream can be passed to a CAM module (if present) for descrambling. This functionality is implemented inside the “TS PID filtering” block. In this case Joker TV can pass packets that belongs only to this one program. For example, full TS contains 10 TV programs but we only need one program. However for some reason, we need to exclude (strip) some Transport Stream packets. This Transport Stream contains all packets without any filtration (Full TS). One of this source can be selected for further processing. Can be used to pass data through Joker TV, for example for descrambling with CAM. USB EP4 – receive Transport Stream from host using USB bulk transfers.

This pattern can be used on the host’s side for data correctness control written on Verilog.

Transport Stream generator – produces Transport Stream packets and fill them with a predefined pattern.

DVB-S2/T2/C2/ISDB-T demodulator (Sony CXD2854ER).

I have also prepared the following diagram for a better understanding:Īs you can see, we have quite a few Transport Stream ( TS) sources: The firmware is fully open source and can be found here.

All described functionalities are written on Verilog and run on Altera FPGA (EP4CE22F17C8N). Hello everybody! This post describes how Transport Stream dataflow within the Joker TV universal USB DTV receiver.
