The HDE-2S-IP (MPEG-2 HD/SD encoder multiplexer - 2xHD-SDI or 8xSD-SDI/NTSC to IP/2xASI) accepts two (2) high definition (HD) programs from HD-SDI inputs or up to eight (8) standard definition (SD) programs across the SDI and/or NTSC inputs. MPEG-2 encoded outputs are multiplexed into one Multi Program Transport Stream (MPTS), which is available in the following formats simultaneously: 1xIP (100/1000 BaseT) and 2xASI. 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 (10/100BaseT).
