Following the dvbs2 specifications, a number of modem configurations and tools are made available for implementing acm in interactive systems. The dvbs standard specifies qpsk modulation and concatenated convolutional and reedsolomon channel coding, and is now used by most satellite operators worldwide for television and data broadcasting services. Az110 is capable of transmitting one mpeg transport stream in dvbs, dvbdsng or dvbs2 mode. Dvbs en 300 421 2 was introduced as a standard in 1994 and dvbdsng en 301 210 3 in 1997. Dvbs2 adaptive coding and modulation for hap communication system. This paper focuses on the profiles supporting interactive type of services, for which adaptive coding and modulation acm has been included in the new generation of the standard.
Satellite communications specialist wins asbu broadcastpro award for its pivotal role in developing new dvbs2 extensions technology dubai, uae, and sintniklaas, belgium, november 20. Tbs6909 dvb s2 8 tuner pcie cards video tutorial for linux users duration. Modulation acm to optimise the transmission parameters 3. Dvb s2 is designed for broadcast services including standard and hdtv, interactive services including internet access, and professional data content distribution. Newtec has been awarded the prestigious accolade of outstanding achievement at the asbu broadcastpro awards for the companys pivotal role. For unicasting applications, the dvbs2 system includes adaptive coding and modulation acm techniques.
Most broadcastorientated dvbs2 systems provide much the same efficiency in likeforlike network profiles. The development of dvb s2 coincided with the introduction of hdtv and h. Dvbs2 acm modes for ip and mpeg unicast applications. Adaptive coding and modulation acm is an enhancement to the dvbs2 standard that. It supports qpsk, 8psk, 16qam, 16apsk, 32apsk modulation schemes.
