The IRT-6750-MEM is a Transport Stream over Internet Protocol (TSoIP) converter that acts as a gateway between an ASI and an Ethernet network environment.
The IRT-6750-MEM is designed to operate independently as either a transmitter (ASI to TSoIP) or receiver (TSoIP to ASI) or can be used as a pair with one unit at each end of an Ethernet link.
When configured as an ASI to TSoIP converter (transmitter mode), the input ASI stream is encapsulated into either UDP or RTP Ethernet packets with controlled scheduling of IP packets to prevent IP jitter. Forward error correction (FEC) in accordance to SMPTE 2022-1 can also be added to the conversion.
An interesting application for the transmitter mode is for visual monitoring of the ASI stream’s content on an Ethernet link by third party software, such as by VideoLAN’s VLC media player (for a single content ASI stream) downloadable as a free download from the internet.
When configured as a TSoIP to ASI converter (receiver mode), the IRT 6750 MEM accepts unicast and multicast IP streams over its Gigabit Ethernet port. The UDP or RTP packets are de-encapsulated with IP jitter removal and error correction applied as per SMPTE 2022-1. The resultant output being either a 188 or 204 byte (settable) ASI signal.
The Ethernet port has automatic MDI/MDI X detection, this detects whether the Ethernet interconnect cable is a straight through or cross over type and automatically switches itself to accommodate, and will automatically select the link speed of the connected network (100/1000Mb/s).
All parameters are set via a preset range of DIP switch settings, or set and read via openGear’s DashBoard™ software control program, or via a Simple Network Management Protocol (SNMP) system. The IRT-6750-MEM is designed to fit the openGear® standard 2RU frames which allow a mixture of cards from various manufacturers to be mounted within the same frame.
The DashBoard control software is available as a free download.
