SDE-6S-ASI (MPEG-2 SD Encoder/Multiplexer – 6xSD-SDI/6xNTSC to 2xASI/IP) accepts up to six (6) standard-definition (SD) programs from any of the following inputs: 6xSD-SDI, and/or 6xNTSC. MPEG-2 encoded outputs are multiplexed into one Multi Program Transport Stream (MPTS) which is available in the following formats simultaneously: 2xASI (mirrored), and 1xIP (100/1000 BaseT). The encoder supports Dolby Digital audio encoding for (16) analog stereo audio pairs (L+R) which in addition to primary and secondary audio programs also provide a third pair for the Audio Descriptor Service, an additional narration track for blind and visually impaired, as mandated by the Twenty-First Century Communications and Video Accessibility Act of 2010 (CVAA). Ad insertion SCTE 35 compliant queuing messages are detected for each program from either the multiple audio Cue Tone inputs or an insertion contact closure (operator selectable). A baseband audio analog encoding capability table is provided on the following page for easy reference. In addition to the baseband audio analog encoding capability audio programs that are already encoded and present on the SDI inputs may be multiplexed with the respective output (pass-through) without utilizing the baseband audio analog encoding resource. The encoder also supports Closed Captioning (EIA-608, and EIA-708), and Emergency Alert System (EAS). A front-panel DVI port is available for real-time monitoring of active programs during operation. Comprehensive remote monitoring and control is accomplished using any standard Web browser via a rear-panel SFP port
