[QUOTE="MCelliotG, post: 998290, member: 404726"] We are seriously going off-topic here, but it was discussed on SDG forum, feel free to move it accordingly if it's a problem. And note I'm not sure if you are referring to the same thing (DVB-H) but that's the closest. This is the tutorial, thanks to Athoik Source:[URL='http://www.satdreamgr.com/forum/showthread.php?14415-How-to-use-DVB-Multiprotocol-Encapsulation&highlight=encapsulation']How to use DVB Multiprotocol Encapsulation[/URL] In order to use DVB-MPE we need to use [B]dvbnet[/B] utility (opkg install dvbnet) and [B]udpxy[/B] (opkg install udpxy). We are going to use 10775 H 27500 2/3 @ 13E for testing. First we need to tune and Satfinder can do that. [IMG]https://s22.postimg.org/3te57sojl/tune.jpg[/IMG] Next we need to use dvbnet in order to create an DVB network interface. We are going to use PID 2001. [CODE]root@osminiplus:~# dvbnet -p 2001[/CODE] [CODE]DVB Network Interface Manager Copyright (C) 2003, TV Files S.p.A Status: device dvb0_0 for pid 2001 created successfully. root@osminiplus:~# dvbnet -l DVB Network Interface Manager Copyright (C) 2003, TV Files S.p.A Query DVB network interfaces: ----------------------------- Found device 0: interface dvb0_0, listening on PID 2001, encapsulation MPE ----------------------------- Found 1 interface(s). Our new DVB network interface created, now let's configure it. We need to add a MAC address and IP in order to bring interface up.[/CODE] [CODE]root@osminiplus:~# ifconfig dvb0_0 dvb0_0 Link encap:Ethernet HWaddr 00:00:00:00:00:00 BROADCAST NOARP MULTICAST MTU:4096 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Base address:0x7d1[/CODE] [CODE]root@osminiplus:~# ifconfig dvb0_0 hw eth 22:33:44:55:66:77 root@osminiplus:~# ifconfig dvb0_0 10.20.30.40 root@osminiplus:~# ifconfig dvb0_0 up root@osminiplus:~# ifconfig dvb0_0 dvb0_0 Link encap:Ethernet HWaddr 22:33:44:55:66:77 inet addr:10.20.30.40 Bcast:10.255.255.255 Mask:255.0.0.0 UP BROADCAST RUNNING NOARP MULTICAST MTU:4096 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Base address:0x7d1[/CODE] Now let's see if we can get any data, tdpdump to the rescue (opkg install tcpdump). [CODE]root@osminiplus:~# tcpdump -i dvb0_0 -vn | head tcpdump: listening on dvb0_0, link-type EN10MB (Ethernet), capture size 262144 bytes 22:40:02.896242 IP (tos 0x98, ttl 128, id 33273, offset 0, flags [none], proto UDP (17), length 1496) 192.168.135.190.6000 > 224.20.20.1.6000: UDP, length 1468 22:40:02.900563 IP (tos 0x98, ttl 128, id 19354, offset 0, flags [none], proto UDP (17), length 1496) 192.168.135.190.6000 > 224.20.20.2.6000: UDP, length 1468 22:40:02.900742 IP (tos 0x98, ttl 128, id 62192, offset 0, flags [none], proto UDP (17), length 1496) 192.168.135.190.6000 > 224.20.20.4.6000: UDP, length 1468 22:40:02.900797 IP (tos 0x98, ttl 128, id 3000, offset 0, flags [none], proto UDP (17), length 40) 192.168.135.190.6000 > 224.20.20.3.6000: UDP, length 12 22:40:02.905635 IP (tos 0x98, ttl 128, id 20161, offset 0, flags [none], proto UDP (17), length 1496) 192.168.135.190.6001 > 224.20.20.1.6001: UDP, length 1468 51 packets captured 226 packets received by filter 0 packets dropped by kernel[/CODE] Our network interface receives multicast packets. Now we need to change those into unicast, updxy to the rescue. We are running manually the udpxy on default port using multicast interface the dvb0_0.

I opened the following URL in VLC [URL]http://osminiplus:4022/udp/224.20.20.1:6000[/URL] but here comes the [B]partial success[/B]...
