Digitalna videoradiodifuzija (DVB) - Radiodifuzijski sistem naslednje generacije za dlančnike, specifikacija fizične plasti (DVB-NGH) - 1. del: Osnovni profil
Ta dokument opisuje sistem prenosa naslednje generacije za digitalno prizemno in hibridno (kombinacija prizemnih in satelitskih prenosov) radiodifuzijo, namenjeno ročno upravljanim terminalom. Določa celoten del fizične plasti od vhodnih tokov do prenesenega signala. Ta sistem prenosa je namenjen prenašanju transportnih tokov ali splošnih podatkovnih tokov v linearne in nelinearne aplikacije, kot so televizija, radio in podatkovne storitve. Terminali DVB-NGH lahko obdelujejo tudi signale DVB-T2-lite.
