This educational from Alexandru Csete during OZ9AEC shows we how to spin your Raspberry Pi into a live HDTV transmitter:
In a prior post we wrote about regulating a UT-100C DVB-T modulator on linux and we betrothed to follow adult how to use a modulator with live video sources. In this post we am going to report how to setup a modulator on a Raspiberry Pi versed with a RaspiCam camera module, effectively branch a Pi into a live HDTV transmitter.
The setup can be done tiny adequate to be carried by a middle distance worker and a operation can be increasing regulating energy amplifiers. If we do that be certain to approve with a radio regulations germane in your country. In particular, transmitting with poignant energy in a UHF TV bands will many expected get we into trouble. Your best gamble is to get a ham radio permit and use a 23 cm band.
The setup we am regulating performs a following tasks:
-Capture H.264-encoded video from a camera regulating a raspivid application.
-Convert a H.264 bitstream to consistent bitrate and DVB agreeable MPEG-TS tide regulating ffmpeg 2.2.2.
-Send a MPEG-TS tide to a UT-100C modulator regulating tsrfsend application.
-In my possess setup we also use a 20 dBm energy upholder to boost a range.
Each Friday is PiDay here during Adafruit! Be certain to check out a posts, tutorials and new Raspberry Pi associated products. Adafruit has a largest and best preference of Raspberry Pi accessories and all a formula tutorials to get we adult and using in no time!
