DVB S2 T2MI Transmission
What is exactly T2-MI & DVB-T2
T2-MI is not type of modulation.This transponder is regular DVB-S2,8PSK,CCM transponder. T2-MI is specialized data format for delivering DVB-T2 multiplexes with timestamps to transmitters over existing channel like IP (UDP/RTP) or DVB over Sat.DVB S2 signal decoded to T2 signals at the trestrial transmitting station then received by home T2 enabled TVs. (The Tp's which is mentioned in Yamal 202 with marking as T2-MI is nothing but the channels coded using T2 Modulator Interface protocol and tunneled in DVB-S2 8PSK signal. This method is used in satellite broadcasting while the DVB-T2 is used in terrestrial transmission). Coming back to the signal, you can use any DVB-S2 receiver to see the signal strength but you won't be able to decode it because almost all commercial receivers available are not having second level decoding.Also you cannot use the DVB-T2 receiver. T2-MI in Detail It uses a Physical Layer Pipe concept.A PLP is a logical channel that may carry one or multiple services. Each PLP can have a different bit rate and error protection parameters. For example, it's possible to split SD and HD services to different PLPs. I hope below image help you in understanding the PLP concept. [IMG]Guests cannot see images and links in the messages.
