Digital Video Transport System

N/Adigital video transport system offers 100% efficient multiple, full payload DVB-ASI transport for MPEG and Video on Demand (VOD) systems. It is well suited for the transport of video services. It transports scrambled video, compressed video, digital video (including uncompressed SMPTE 259M/ITU-601 and DVB-ASI 270 Mbps video), multiplexed, modulated video (such as 64/256 QAM, 8 VSB and other popular formats) and video for feeding wireless video systems, such as MMDS. It also transports high-speed data (including telephony signals like DS1/DS3 and E1/E3, and LAN signals like 10BaseT and 100BaseTX Ethernet/IEEE 802.x) and voice signals.

The 270 Mbps DVB-ASI interface cards give operators the capability to transport multiple, full-payload DVB-ASI signals - 211Mbps - over DV6000 fiber optic networks. With Dense Wavelength Division Multiplexing, N/Acan transport 72 DVB-ASI streams, or over 4000 + broadcast quality MPEG-encoded videos, all over one fiber. The DVB-ASI card has the ability to deliver the full DVB-ASI data rate. DVB-ASI has a transmission rate of 270 Mbps. 20% of this capacity is lost due to data encoding schemes used for forward error correction (FEC) and signal robustness, dropping usable data capacity to 216 Mbps. An additional 5 to 6 Mbps are used for synchronization, leaving a total usable payload capacity of 211 Mbps. Currently, DVB-ASI streams from signal generation equipment such as video servers and (re)multiplexers can only produce data rates (payloads) between 90 and 150 Mbps.
