摘要：In this paper, a Digital Video Broadcasting-2nd Generation (DVB-x2) broadcast gateway with Common Modulator Inter- face (CMI) is presented for all the DVB-x2 services such as DVB-T2 for terrestrial, DVB-C2 for cable, and DVB-S2 for satellite. As a single platform, it is designed and implemented to support any remotely distributed DVB-x2 modulators by the CMI based on the T2-MI protocol for DVB-T2. In addition, it consists of a broad gateway control, an input pre-processor, a common mode adaptation, a common stream adaptation, a common layer generator, and a CMI packet generator. The experimental results shows that it can improve the bu.er usage by about 24% at the cost of only about 3% overhead increase, compared to the use of separate DVB-T2/C2/S2 bu.ers
