ATSC mobil A-VSB MCAST och fysiska skikt för ATSC-M/HH

摘要

The Mobile Broadcasting (A-VSB MCAST) design consists of transport and signaling opt imized for mobile and handheld services. Section 5 provides the overall A-VSB MCAST architecture. Section 6 specifies the physical and link layers. Section 7 specifies the trans port layer. And, Section 8 describes the frame slicing mechanism for burst transmission. Backwards compatibility is ensured by the careful design of the physical and link layers. Field tests are well underway now, being overseen by ATSC TSG/S9.
