EN 60958-4-4:2016

Digital audio interface - Part 4-4: Professional applications - Physical and electrical parameters

IEC 60958-4-4:2016 specifies the physical and electrical parameters for different media. This part together with IEC 60958-1, IEC 60958-4-1, and IEC 60958-4-2 specify an interface for the serial digital transmission of two channels of periodically sampled and linearly represented digital audio data from one transmitter to one receiver. This first edition, together with IEC 60958-4-1 and IEC 60958-4-2, cancels and replaces the IEC 60958-4 published in 2003 and its Amendment 1:2008 and constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 60958-4:2003 with its Amendment 1:2008: - support for a wider range of physical media; - support for a wider range of audio sampling frequencies; - deprecation of "minimum implementation" of channel status data.

Interface audionumérique - Partie 4-4: Applications professionnelles - Paramètres physiques et électriques

L'IEC 60958-4-4:2016 spécifie les paramètres physiques et électriques des différents supports. Cette partie avec l'IEC 60958-1, l'IEC 60958-4-1 et l'IEC 60958-4-2 précisent conjointement une interface de transmission numérique en série de deux voies de données audionumériques échantillonnées de façon périodique et représentées de façon linéaire entre un émetteur et un récepteur. Cette première édition, avec l'IEC 60958-4-1 et l'IEC 60958-4-2, annule et remplace l'IEC 60958-4 parue en 2003 et l'Amendement 1:2008 et constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'IEC 60958-4:2003 et son Amendement 2008: - prise en charge d'une gamme plus large de supports physiques; - prise en charge d'une gamme plus large de fréquences d'échantillonnage audio; - "mise en oeuvre minimale" des données de la voie de signalisation déconseillée.

Digitalni avdio vmesnik - 4-4. del: Profesionalna uporaba - Fizični in električni parametri (IEC 60958-4-4:2016)

Ta del standarda IEC 60958 opredeljuje fizične in električne parametre različnih medijev. Ta del skupaj s standardi IEC 60958-1, IEC 60958-4-1 in IEC 60958-4-2 opredeljuje vmesnik za serijski digitalni prenos dveh kanalov periodično vzorčenih in linearno predstavljenih digitalnih zvočnih podatkov od določenega oddajnika do določenega sprejemnika.
Transportni format, opredeljen v standardu IEC 60958-1, je namenjen za uporabo z oklopljeno parico na razdalji do 100 m brez uravnavanja prenosa ali drugega posebnega uravnavanja pri sprejemniku v okvirnih vrednostih do 50 kHz. Lahko se uporabijo večje dolžine kablov in višje okvirne vrednosti, vendar to zahteva dodatno previdnost pri izbiri kablov in morebitno uravnavanje sprejemnika ali uporabo aktivnih ponavljalnikov, ali oboje. V tem standardu je določba za prilagoditev simetričnih terminalov za uporabo koaksialnega kabla 75 Ω, obravnavan pa je tudi prenos prek optičnega kabla. Ta standard ne zajema povezave z opremo običajnega operaterja. V tej specifikaciji vmesnika je omenjen tudi vmesnik za potrošniško uporabo. Vmesnika nista identična.
