Standardutveckling · SIS/TK 302

Multimedia, kodning och representation

Gemensamma standarder är en förutsättning för interoperabilitet mellan utrustning från olika tillverkare. Det är därför viktigt att ta fram enhetliga komprimerings-, lagrings- och transportformat för ljud, bild och video som ska kunna användas för det stora antal tjänster och skärmar och andra apparater som finns på nuvarande och framtida marknader. Som tjänster kan nämnas digital TV/radio, musik- och video-streaming, interaktiva XR tjänster, och som apparater TV, radio, set-top boxar, mediaspelare, mobiltelefoner, huvudmonterade skärmar, AR glasögon, etc.

Utgångspunkter i kommitténs arbete

Kommittén ska aktivt delta, påverka, utveckla standarder och bevaka svenska intressen inom området multimedia, kodning och representation och verka för en hög kvalitet på de standarder som tas fram.

Användande av standarder inom kommitténs omfattning

Standarderna används till att utveckla interoperabla produkter och tjänster inom multimediaområdet.  Exempelvis strömmande audio och video.
