IP to ASI / ASI to IP Bridge

[Bill Song@UBS]

Models: DV-IP-ASI-1G




Overview

In today’s broadcast environment, IP networks have become a very important part in the distribution of digital video streams.
The DVB-ASI-to-IP Bridge is designed to achieve the highest performance,
while satisfying all requirements of MPEG transport stream distribution in SFN networks. It provides DVB-ASI-to-IP or IP-to-DVB-ASI conversion and can be used to transfer a MPEG transport stream though an IP network.
The unit supports full DVB-ASI bandwidth operation (up to 216 Mbps) on both Ethernet ports and simultaneous operation in both directions.
Different combinations of two DVB-ASI ports and two Gigabit Ethernet ports are possible. Data and Control IP streams can be applied to either Ethernet port.
