Step 1. Install TV Tuner Drivers
I use four Hauppuage WinTV-HVR-955Q TV Tuners
Step 2. Attach Digital Antenna
Setup the digital TV antenna. Run a coax cable to a coax splitter. Each split drops the signal strength by 3dB, which means it is cut in half. Since I am going to use one antenna with 4 tuners and I live about 20 miles from the Broadcast TV Towers, I use a powered antenna to amplify the signal.
I used short coax cables for the splitter to the tuners. I couldn't get all four tuners plugged in and so I used short USB cables for the PC ports to the USB tuners.
Step 3. Attach one TV Tuner to the PC and reboot the ubuntu PC
$ sudo reboot
Step 4. Check if it works
Login to and run the command to check if tuner is recognized.
Open a terminal window
$ dmesg | grep dvb
[ 4.232615] cx231xx 1-1.5:1.1: Successfully loaded cx231xx-dvb
[ 4.232639] cx231xx 1-1.5:1.1: Cx231xx dvb Extension initialized
If there are issues such as a missing driver, then you have the wrong TV Tuner or the wrong version of the kernel or ubuntu installed. With a different TV Tuner, I spent a lot of time trying to resolve these issues by downloading drivers and rebuilding the kernel. It really wasn't worth the time. I returned the tuner to Amazon and got the right one. So, much easier.
Another way to check if it is working is to run the command:
$ ls /dev/dvb
adapter0
