12:1 ASI-to-IP Multiplexer
12:1 ASI-to-IP Multiplexer


Product Code: BLT-MUX-12A-IP2


MUX-12A-IP (12:4 ASI-to-IP Multiplexer; 12xASI > 4xIP) is designed for cherry-picking applications, allowing operators to create custom-made channel lineups by grooming standard-definition (SD) and high-definition (HD) programs on an as-needed basis. The multiplexer accepts up to twelve (12) unencrypted MPEG-2/H.264 inputs in ASI format and multiplexes them into up to four (4) MPEG-2/H.264 Multi-Program Transport Streams (MPTS) which are then encapsulated and assigned to up to four (4) IPv4 addresses in 1000Base-T Ethernet (GigE) format suitable for distribution over Cat-5 networks. Any two (2) of the four (4) MPTS output streams are also available in ASI format. Each ASI input stream can contain up to 20 unencrypted programs, for a total of 240 input programs. The GigE output can contain up to 20 programs groomed in up to four (4) MPTS output streams from any of the available 240 input programs, each MPTS output stream not to exceed 214 Mbps, and the sum of programs in all MPTS output streams not to exceed 20. The multiplexer is EAS-compliant (Emergency Alert System) – operator can assign ASI port #12 as an EAS input which, when activated, will override the content of all other ASI inputs. Comprehensive remote monitoring and control is accomplished via a GUI-based interface using any standard web browser.
