Cable networks for television signals, sound signals and interactive services - Part 101-2: Performance requirements for signals delivered at the system outlet in operation with all-digital channels load

IEC 60728-101-2:2023 provides the minimum performance requirements to be fulfilled in operation at the system outlet or terminal input and describes the summation criteria for the impairments present in the received signals and those produced by the CATV/MATV/SMATV cable network, including individual receiving systems. In a building divided into apartment blocks, the signals received by the antennas are distributed by the MATV/SMATV cable network up to the home network interface (HNI); the television signals are then distributed (inside the home) by home networks (HN) of various types up to the system outlet or terminal input. The cable network can support two-way operation, from the system outlet (or terminal input) towards the headend. The home network can use coaxial cables, balanced pair cables, fibre optic cables (glass or plastic) and also wireless links inside a room (or a small number of adjacent rooms) to replace wired cords. This part of IEC 60728 is limited to downstream TV broadcast signals received from antennas and is applicable to cable networks intended for television signals, sound signals and interactive services operating between about 5 MHz and 3 300 MHz. The frequency range is extended to 6 000 MHz for home distribution techniques that replace wired cords with a wireless two-way communication inside a room (or a small number of adjacent rooms) that uses the 5 GHz to 6 GHz frequency band. The main sections of a general CATV/MATV/SMATV system, indicating the parts of the IEC 60728-101 series documents where the relevant performance requirements are indicated. - The requirements for the signals received at the headend are given in IEC 60728-101:2016, Clause 6. - The requirements for the CATV/MATV/SMATV cable network, assuming an unimpaired input signal at the input of the headend, up to the system outlet are given in IEC 60728‑101:2016, Clause 5. - The requirements for the CATV/MATV/SMATV cable network up to the home network interface (HNI) are given in IEC 60728-101:2016, Clause 7, assuming an unimpaired input signal at the input of the headend. - The specific requirements from HNI to the system outlet or terminal input are given in IEC 60728-101-1:2023, Clause 5, assuming an unimpaired input signal at the HNI. - The requirements at the system outlet in operation are given in Clause 6 of this document. The expression "in operation" means that the received signals, with their impairments, are applied to the headend input of the CATV/MATV/SMATV cable network. The requirements at the system outlet "in operation" are derived, therefore, by summing the impairments of the various cascaded parts of the system and of the input signal. When a change of signal format from digital to digital (e.g. from QPSK to QAM) (e.g. as in ETSI EN 300 473) or from digital to analogue (e.g. from DVB-S/S2 to AM-VSB or DVB-T/T2 to AM-VSB) is made at the headend, the summation of the impairments that produce a relaxation of requirements at system outlet does not apply. Such a case will be the equivalence of unimpaired signals applied at the headend input. Therefore, the requirements at system outlet given in IEC 60728‑1 apply. This document also provides references for the basic methods of measurement of the operational characteristics of the downstream cable network in order to assess its performance. All requirements refer to the performance limits to be achieved in operation at any system outlet when terminated in a resistance equal to the nominal load impedance of the system, unless otherwise specified. Where system outlets are not

Réseaux de distribution par câbles pour signaux de télévision, signaux de radiodiffusion sonore et services interactifs - Partie 101-2: Exigences de performance relatives aux signaux délivrés à la prise d'abonné en fonctionnement sous une charge de porteuses exclusivement numériques

L'IEC 60728-101-2:2023 fournit les exigences de performances minimales qui doivent être respectées en fonctionnement au niveau de la prise d'abonné ou de l'entrée de terminal, et décrit les critères de sommation pour les dégradations présentes dans les signaux reçus et celles générées par le réseau de distribution par câble CATV/MATV/SMATV, y compris les systèmes de réception individuels. Dans un bâtiment divisé en blocs d'appartements, les signaux reçus par les antennes sont distribués par le réseau de distribution par câble MATV/SMATV jusqu'à l'interface de réseau domestique (HNI). Les signaux de télévision sont ensuite distribués (à l'intérieur du domicile) par différents types de réseaux domestiques (HN) jusqu'à la prise d'abonné ou l'entrée de terminal. Le réseau de distribution par câble peut prendre en charge un fonctionnement bidirectionnel, de la prise d'abonné (ou l'entrée de terminal) vers la tête de réseau. Le réseau domestique peut utiliser des câbles coaxiaux, des câbles à paires symétriques, des câbles à fibres optiques (verre ou plastique) ainsi que des liaisons sans fil à l'intérieur d'une pièce (ou d'un nombre restreint de pièces adjacentes) pour remplacer les cordons câblés. La présente partie de l'IEC 60728 se limite aux signaux de diffusion TV en aval émis par des antennes et s'applique aux réseaux de distribution par câble destinés aux signaux de télévision, aux signaux de radiodiffusion sonore et aux services interactifs qui fonctionnent entre environ 5 MHz et 3 300 MHz. La plage de fréquences est étendue à 6 000 MHz pour les techniques de distribution domestique qui remplacent les cordons câblés par une communication bidirectionnelle sans fil à l'intérieur d'une pièce (ou d'un nombre restreint de pièces adjacentes) qui utilise la bande de fréquences comprise entre 5 GHz et 6 GHz. Les principales sections d'un système CATV/MATV/SMATV général, en précisant les parties des documents de la série IEC 60728-101 dans lesquelles les exigences de performances pertinentes sont indiquées. - Les exigences relatives aux signaux reçus au niveau de la tête de réseau sont données à l'Article 6 de l'IEC 60728-101:2016. - Les exigences relatives au réseau de distribution par câble CATV/MATV/SMATV, en prenant pour hypothèse un signal d'entrée dégradé à l'entrée de la tête de réseau, jusqu'à la prise d'abonné, sont données à l'Article 5 de l'IEC 60728 101:2016. - Les exigences relatives au réseau de distribution par câble CATV/MATV/SMATV jusqu'à l'interface de réseau domestique (HNI) sont données à l'Article 7 de l'IEC 60728-101:2016, en prenant pour hypothèse un signal d'entrée non dégradé à l'entrée de la tête de réseau. - Les exigences spécifiques entre la HNI et la prise d'abonné ou l'entrée de terminal sont données à l'Article 5 de l'IEC 60728-101-1:2023, en prenant pour hypothèse un signal d'entrée non dégradé à la HNI. - Les exigences au niveau de la prise d'abonné en fonctionnement sont données à l'Article 6 du présent document. L'expression "en fonctionnement" signifie que les signaux reçus, avec leurs dégradations, sont appliqués à l'entrée de tête du réseau de distribution par câble CATV/MATV/SMATV. Les exigences au niveau de la prise d'abonné "en fonctionnement" sont donc déduites par sommation des dégradations des différentes parties en cascade du système et du signal d'entrée.

Kabelska omrežja za televizijske in zvokovne signale ter interaktivne storitve - 101-2. del: Zahteve za zmogljivost za signale na izhodu sistema pri delovanju pod obremenitvijo vseh digitalnih kanalov (IEC 60728-101-2:2023)

Standard IEC 60728-101-2:2023 določa minimalne zahteve glede zmogljivosti, ki morajo biti izpolnjene med obratovanjem sistemskega izhoda ali vhodnega terminala in opisuje merila za seštevanje oslabitev, ki so prisotne v sprejetih signalih in tistih, ki jih ustvarja kabelsko omrežje CATV/MATV/SMATV, vključno s posamičnimi sistemi za sprejem.
V stanovanjskih blokih se signali, ki jih sprejemajo antene, distribuirajo prek kabelskega omrežja MATV/SMATV v domači omrežni vmesnik, nato pa se televizijski signali distribuirajo (znotraj doma) prek domačih omrežij različnih vrst v sistemski izhod ali vhodni terminal. Kabelsko omrežje lahko podpira dvosmerno delovanje, od sistemskega izhoda (ali vhodnega terminala) proti glavni sprejemni postaji.
Domače omrežje lahko uporablja koaksialne, simetrične parne in optične (steklene ali plastične) kable ter tudi brezžične povezave znotraj sobe (ali manjšega števila sosednjih sob) namesto žičnih kablov.
Ta del standarda IEC 60728 je omejen na televizijske radiofuzivne signale, sprejete prek anten in se uporablja za kabelska omrežja, namenjena televizijskim signalom, zvokovnim signalom in interaktivnim storitvam, ki delujejo s frekvenco med približno 5 MHz in 3300 MHz. Frekvenčni razpon se poveča na 6000 MHz pri domačih distribucijskih tehnikah, ki nadomeščajo žične kable z brezžično dvosmerno komunikacijo znotraj sobe (ali manjšega števila sosednjih sob), ki uporablja pas med 5 GHz in 6 GHz.
Navedeni so glavni sklopi splošnega sistema CATV/MTAV/SMATV z navedbo delov dokumentov skupine standardov IEC 60728-101, kjer so navedene pomembne zahteve glede zmogljivosti.
– Zahteve za signale, ki se jih prejema na glavni sprejemni postaji, so navedene v točki 6 standarda IEC 60728-101:2016.
– Zahteve za kabelsko omrežje CATV/MATV/SMATV, ob predvidenem neoslabljenem vhodnem signalu na vhodu glavne sprejemne postaje do sistemskega izhoda, so podane v točki 5 standarda IEC 60728-101:2016.
– Zahteve za kabelsko omrežje CATV/MATV/SMATV do domačega omrežnega vmesnika so podane v točki 7 standarda IEC 60728-101:2016, ob predvidenem neoslabljenem vhodnem signalu na vhodu glavne sprejemne postaje.
– Posebne zahteve od domačega omrežnega vmesnika do sistemskega izhoda ali vhodnega terminala so podane v točki 5 standarda IEC 60728-101-1:2023, ob predvidevanju neoslabljenega vhodnega signala na domačem omrežnem vmesniku.
– Zahteve na sistemskem izhodu pri delovanju so podane v točki 6 tega dokumenta.
Izraz »pri delovanju« pomeni, da so sprejeti signali z oslabitvami uporabljeni na vhodu glavne sprejemne postaje kabelskega omrežja CATV/MATV/SMATV. Zahteve na sistemskem izhodu »pri delovanju« so tako izpeljane s seštevanjem oslabitev različnih kaskadnih delov sistema in vhodnega signala.
Pri spremembi oblike signala iz digitalnega v digitalni (npr. iz QPSK na QAM) (npr. kot pri standardu ETSI EN 300 473) ali iz digitalnega v analogni (npr. iz DVB-S/S2 v AM-VSB ali DVB-T/T2 v AM-VSB) na glavni sprejemni postaji se seštevanje oslabitev, ki sproščanje zahtev na sistemskem izhodu, ne uporablja. Ta primer je enakovreden neoslabljenim signalom na vhodu glavne sprejemne postaje. Za to veljajo zahteve na sistemskem izhodu, podane v standardu IEC 60728-1.
Ta dokument prav tako vsebuje sklice za osnovne metode merjenja operativnih značilnosti kabelskega omrežja na nižji ravni za ocenjevanje njegovega delovanja.
Vse zahteve se nanašajo na omejitve delovanja, dosežene pri delovanju na katerem koli sistemskem izhodu, kadar je prekinjen z uporom, enakim nazivni obremenitvi impedance sistema, razen če je drugače opredeljeno.
