NEXIO® Transport Stream Delay Server

New to the NEXIO® compressed domain server line, the NEXIO® NX1010DS records one or more transport streams for re-transmission after a specified time period.

With the NX1010DS transport stream delay server, input and output streams are decoupled; one input stream can support several output streams, each with different delays. For example, if you want to delay one stream to three different time zones (e.g., one with one-hour delay, one with two-hour delay and one with three-hour delay), you only need to record the one stream, and create three delayed output streams.

The transport stream can be either ASI or IP (unicast, multicast, UDP, or RTP); input and output types are independent (i.e., you can ingest a stream over ASI and output it delayed over IP, and vice versa). IP input/output is standard via dual Gigabit Ethernet ports; ASI I/O ports and additional Gigabit Ethernet ports may be added as optional I/O cards.

The transport stream delay server includes 300 GB usable internal storage on two internal hard drives and uses RAID striping to enhance performance, supporting up to 200 Mb/s of delay stream throughput. This provides enough storage to support approximately 30 hours of delay for a single 20 Mb/s stream or three hours of delay for the full 200 Mb/s throughput. The server may be connected to an external network attached storage (NAS), such as the Harris® NXIQ™ storage server, if more storage capacity is required. Care should be taken to ensure that storage and network bandwidth are sufficient to ensure reliable transport stream record and playback.

The NX1010DS can delay up to 30 streams, making it very useful for customers who need to delay many low bitrate streams in an IP environment.
