SEL-MDX1
Transport Stream Multiplexer/Demultiplexer
The Selenio SEL-MDX1 encapsulator and multiplexer module makes it easy to multiplex, demultiplex, remultiplex or encapsulate streams for transport. Incoming programs can be readily repurposed into new programs, local content (commercials, news and more) can be easily added to existing programs, and new transport streams can be quickly generated.
The unique internal connectivity in the Selenio platform provides unprecedented flexibility. Content can be easily routed from a variety of sources, including MPEG-2 and H.264 encoder modules, various internal network interfaces such as DVB-ASI, and incoming transport streams from Gigabit Ethernet.
With features including DVB scrambling and conditional access (CA) enabled by a Simulcrypt interface, the Selenio multiplexer is ideal for contribution and distribution functions, as well as Direct-to-Home (DTH) market applications.

Product Details
The Selenio multiplexer is capable of accepting unencrypted programs from a variety of sources — from local encoders to network interfaces, including ASI or Gigabit Ethernet. It includes a Simulcrypt synchronizer to request information from a conditional access system over a dedicated Ethernet connection. Each program is encrypted using DVB common scrambling, and Entitlement Control Messages (ECM) are multiplexed into each stream to provide a DVB-compliant output.
The encryption engine supports 240 user-accessible simultaneous programs at a combined rate of up to 214 Mb/s. When not using encryption, the multiplexer supports up to an 800 Mb/s throughput.
External connections can include up to eight software-selectable independent inputs or outputs that can handle either DVB-ASI or the SMPTE 310M protocols.
Back Module Connectivity
The SEL-MDX1 mux/demux application module offers two choices for back module external connectivity ― one with HD-BNC electrical connections for eight input or output ASI signals and one with HD-BNC electrical connections for five input or output ASI signals, and RJ-45 100Base-T connectivity to support conditional access.
SDI and ASI interfaces utilize a Belden-type 1505A, 1694A or 1695A cable with HD-BNC connectors. A cable removal tool is provided for these types of HD-BNC connections.
