Page 12 Due to the improvement that LMS-T has over DVB-T these settings give approximately 50% improvement of bit rates for the same level of ruggedness of the RF link. For example DVB-T 16QAM, 1/32 GI, 1/2 CR gives 12Mbits whereas LMS-T 16QAM gives 18Mbits ASI Operation The L1500 can be used as an MPEG2 HD encoder providing an ASI output.
Page 13 1 … 2000 ms Link’s interleaving scheme does not touch the encoded bit stream from the transmitter other than to add extra data. It is this extra data that is interleaved. This effect of this is that when a break in RF occurs that is longer than the set burst length, then the break in signal seen at the receiver is the same as the original RF break.
