Turn your Raspberry Pi into a live HDTV transmitter

In a previous post I wrote about using the UT-100C DVB-T modulator on linux and I promised to follow up how to use the modulator with live video sources. In this post I am going to describe how to setup the modulator on a Raspiberry Pi equipped with a RaspiCam camera module, effectively turning the Pi into a live HDTV transmitter.

Building the UT-100 driver on the Raspberry Pi

Building the UT-100 driver module on the Raspberry Pi can be done the same way as on the desktop. The only difference is that instead of “sudo apt-get install”-ing the kernel headers and sources we have to fetch them from the Raspberry Pi git repository and install them manually. Although my instructions are written with the UT-100C DVB-T modulator in mind, the procedure is applicable to other out of tree kernel modules as well.

Using the UT-100 DVB-T modulator on Linux

In October last year I learned about the UT-100 series of DVB-T modulators available from a company in Taiwan. At that time I have already been working with software defined video broadcasting; however, I still found the idea of a small USB-stick modulator very appealing for use with embedded devices. In this post I have collected my notes about setting up and testing the UT-100 modulator on Linux.
