This SMP 351 dual recording license lets the processor capture two separate MP4 files — Channel A and Channel B — from a single unit, plus unlocks advanced audio DSP for level control, filtering, and dynamics.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eBy default, the SMP 351 3G-SDI 400 GB composites its two encoding windows into a single output file. This LinkLicense changes that behavior so the processor records Channel A and Channel B as two independent MP4 files, and streams two independent videos in Dual Record mode — well suited to broadcast and production environments taking a 3G-SDI camera feed alongside a content source, with the larger 400 GB internal drive giving more headroom for longer recording archives before offloading. The same license also unlocks advanced audio DSP capabilities on the unit, including level control, filtering, and dynamics processing, improving recorded audio quality without an external DSP box in the rack. Because it is a software entitlement, the upgrade is installed via the SMP's embedded configuration page and takes effect immediately — no card swap or hardware downtime. This license pairs naturally with the SMP 351's Kaltura, Panopto, or YuJa integration licenses for automated publishing of the resulting independent recordings.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndependent dual-channel recording\u003c\/strong\u003e — Captures Channel A and Channel B as two separate MP4 files instead of one composite.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Record streaming\u003c\/strong\u003e — Streams two independent video feeds simultaneously in Dual Record mode.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvanced audio DSP\u003c\/strong\u003e — Unlocks level control, filtering, and dynamics processing on the SMP 351 3G-SDI.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e400 GB recording headroom\u003c\/strong\u003e — Pairs with the larger internal drive for longer archive windows between offloads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePer-processor licensing\u003c\/strong\u003e — One license activates one SMP 351 3G-SDI 400 GB unit for the life of the unit.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTypical Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBroadcast and production rooms combining SDI camera and content sources\u003c\/li\u003e\n\u003cli\u003eMulti-session recording archives before offload to storage\u003c\/li\u003e\n\u003cli\u003eLecture capture requiring separate speaker and content recordings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cdiv style=\"overflow-x:auto;\"\u003e\u003ctable style=\"table-layout:fixed;min-width:0;width:100%;border-collapse:collapse;\"\u003e\n\u003ccolgroup\u003e\n\u003ccol style=\"width:45%\"\u003e\n\u003ccol style=\"width:55%\"\u003e\n\u003c\/colgroup\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;\"\u003e\u003cstrong\u003eProduct type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;\"\u003eSoftware entitlement (LinkLicense)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;\"\u003e\u003cstrong\u003eCompatible hardware\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;\"\u003eSMP 351 w\/ 3G-SDI 400 GB Streaming Media Processor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;\"\u003e\u003cstrong\u003eFunction\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;\"\u003eIndependent dual-channel MP4 recording; advanced audio DSP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;\"\u003e\u003cstrong\u003eDelivery\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;\"\u003eLicense key applied via SMP embedded web page; no additional hardware\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;\"\u003e\u003cstrong\u003ePart number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;\"\u003e79-2547-04\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003c\/div\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eDoes this license require new hardware?\u003c\/strong\u003e\u003cbr\u003eNo. It is a software entitlement applied to an existing SMP 351 3G-SDI 400 GB processor.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this license specific to the 3G-SDI, 400 GB model?\u003c\/strong\u003e\u003cbr\u003eYes.
