vxStatMux
Every channel on the multiplex competes for the same bits. vxStatMux hands them out by picture quality instead of raw bitrate — reallocating the transport stream budget frame by frame, on every channel, around the clock.
Every channel deserves a fair share of bits.
Legacy StatMux treats every channel the same. vxStatMux treats every frame on its merits.
Today - Without vxStatMux
- Every channel gets a profile sized for its worst scene — the pool is over-provisioned all day
- Channels compete on raw bitrate — an HEVC channel is penalised against H.264 by design
- Ad breaks and programme transitions arrive unannounced — quality spikes on the way back
- Quality problems reach subscribers before they reach the headend
- Adding a channel to a full MPTS means buying capacity, not reallocating it
With vxStatMux
- Budget follows scene complexity in real time — action gets the bits it needs, always
- Every channel competes on quality, not bitrate — codec differences normalised automatically
- Schedule-aware pre-allocation smooths transitions — no artefacts at the moment of cut
- Perceptual quality scores drive the allocation, frame by frame, on every channel
- The same MPTS carries more channels at the same picture quality — capacity freed, not bought
Cable, IPTV and broadcast. One pool, handed out by quality.
Where the savings come from.
Four outcomes vxStatMux delivers on standard server hardware — no new appliances required.
Cut Transmission Costs Without Touching Quality
Static profiles over-provision every channel so it can survive its own worst scene. vxStatMux holds the transport stream budget fixed and lets channels trade bits inside it — capacity a studio show isn’t using goes straight to the match that needs it. Transponder and IP transit bills drop. Picture quality stays.
Deliver Objectively Better Picture on Sport & Film
Stadium crowds, fast action, cinema close-ups, dark scenes — the system anticipates them before encoding begins and pre-allocates the bits required. The programme schedule and its ad breaks are known in advance, so the budget rises before the cut instead of catching up after it. No macroblocking during a goal, no banding in a night scene.
Mixed Codec Pools That Compete Fairly
An HEVC channel needs fewer bits than H.264 for the same picture. Legacy StatMux compares raw bitrate and hands both the same budget — one channel over-delivers while the other starves. vxStatMux normalises every channel onto one perceptual quality scale, so the budget is won on how the picture looks, not on which encoder produced it.
Deploy in Days, Not Months
vxStatMux runs on standard server hardware, new or used — no proprietary appliance, no cloud subscription, no per-channel licensing. One unit carries several MPTSes, and with an accelerator 20–30 channels into any MPTS configuration. Integration with your existing multiplexing infrastructure is measured in days, and data never leaves your network.
Proven in production headends.
Three scenarios where vxStatMux turns transport stream capacity into a measured, contractual advantage.
Sport & Live Event Headend
Ten mixed HD channels share a 36 Mbps transport stream. Sport events take an automatic budget uplift through fast action; news and infomercials release the capacity they are not using, in real time. No manual intervention at the headend, no scheduled profile changes.
MPEG-2 to HEVC Migration
Thirty SD channels move from MPEG-2 to HEVC inside the same transport stream. Channels mid-migration compete on quality rather than raw bitrate, so the two codecs share one pool without penalising the newer one. Before/after quality data validates the new profile ladder and justifies the investment.
Premium Tier Quality Floor
A premium cable package guarantees picture quality on sport and film. vxStatMux carries a quality target per channel: premium channels never drop below their floor, filler channels release the bits that keep them there. vxQuality System supplies the continuous scores behind the contractual report.
Your subscribers judge quality in seconds.
The headend has to be faster — on every channel in the pool, on every frame.
