Modern channels are high-bitrate VBR. In fixed CBR muxes you fit maybe three per mux before overflow — so you spread dozens of muxes across the entire band, push QAM-256 everywhere, and now your whole plant has to be perfect: amplifier linearity, tilt, return loss, cable condition across hundreds of MHz. One weak spot anywhere and subscribers get artifacts, dropouts, and truck rolls.

TSC statmux packs all those VBR channels into a handful of muxes — the peaks of one channel fill the valleys of another. You occupy a small, contiguous slice of spectrum instead of the whole band, and you spend the freed spectrum on robustness instead of cramming.

You set the pool; TSC allocates the bits. Define how many channels, the total MPTS bitrate, and per-channel minimum, maximum and priority. TSC allocates bitrate in real time by scene complexity — busy motion gets more, static scenes hand bits back — so the aggregate always stays inside your fixed transport budget with minimal null padding.

It counts most where spectrum is scarce to begin with. An MMDS licence gives you twelve carriers at best — and the band is often shared between two providers with a guard channel between them, leaving one with six and the other with five. Or you hold three DVB-T2 multiplexes and that is the whole estate. At five carriers — let alone three — statmux is not an optimisation, it is the only way to put a line-up on air that anyone will pay for.

This is the same class of dynamic, scene-aware rate control as AWS Elemental Statmux — delivered as software on your own GPU hardware, integrated in the same box as transcode, playout, delivery and billing, with no per-node broadcast-encoder licensing.
