[QUOTE="deeptho, post: 1133469, member: 215446"] What I did was to prepare the transmission before hand (nothing live for this experiment). For this I used 7 music videos. Using ffmpeg I converted those to mpreg program streams. Then, again using fmpeg, I merged the streams into a fixed bit rate transport stream of about 22MBit/s Then a gnuradio flowgraph called dvbt_tx_8k, I put it on the air at 492.25 Mhz and a bandwith of 9Mhz (probably a bit on the marge side) and at very low power. I could scan this mux on a TV and watch the videos each as a seperate TV program. Some videos ended earlier than others. The corresponding TV channels disappeared when video's ended. The stream played as a loop. [/QUOTE]
