Cable networks for television signals, sound signals and interactive services - Part 2-2: Interference issues for DVB-T reception in the presence of LTE base station signals

The Technical Reports describes the interference situation which may occur when besides the wanted broadcast signals of DVB-T/-T2 formats also signals from base stations of mobile radio services (unwanted signals) are received by the same terrestrial broadcast antenna and by an active equipment (amplifier) directly connected to the antenna output. The TR relates in a first step to the special frequency neighbourhood situation between DVB-T signals up to 790 MHz (channel 60) and LTE base station signals starting at 791 MHz. This neighbourhood situation is currently already in operation in many European countries. The TR proposes different measures by which such interference situations can be reduced to an acceptable level or can even be completely avoided. Measures are described for application in already installed networks and also in new networks to be installed in the future.

Kabelska omrežja za televizijske in zvokovne signale ter interaktivne storitve - 2-2. del: Vprašanje motenj za sprejem DVB-T pod vplivom signalov baznih postaj

Standardi in izsledki skupin standardov EN 50083 (vsi deli) in EN 60728 (vsi deli) obravnavajo kabelska omrežja, vključno z opremo in povezanimi metodami za merjenje sprejema glavne sprejemne postaje, obdelavo in distribucijo televizijskih in zvokovnih signalov ter za obdelavo, povezovanje in oddajanje vseh vrst podatkovnih signalov za interaktivne storitve prek vseh primernih prenosnih medijev. Ti signali se v omrežjih običajno prenašajo s tehnikami multipleksiranja frekvenc. To na primer vključuje a) regionalna in lokalna širokopasovna kabelska omrežja, b) razširjene satelitske in prizemne televizijske distribucijske sisteme, c) posamezne satelitske in prizemne televizijske sprejemne sisteme ter vse vrste opreme, sistemov in naprav, uporabljene v tovrstnih kabelskih omrežjih, distribucijskih in sprejemnih sistemih. To standardizacijsko delo med drugim zajema antene in/ali posebne vhode virov signalov v glavno sprejemno postajo ali druge vmesniške točke do omrežja vse do vhodnega terminala opreme v prostorih stranke. To standardizacijsko delo bo upoštevalo soobstoj uporabnikov radiofrekvenčnega spektra v ožičenih in brezžičnih prenosnih sistemih. Standardizacija poljubnih uporabniških terminalov (tj. uglaševalnikov, sprejemnikov, kodirnikov, večpredstavnostnih terminalov itd.) in poljubnih povezanih koaksialnih, simetričnih in optičnih kablov ter opreme je izključena.
