Cable networks for television signals, sound signals and interactive services - Part 5-1: IP gateways and interfaces for headends

Scope

This Technical Report is an adjunct to the EN 60728/EN 50083 standards series and describes the characteristics of equipment which is used for the connection of IP based networks to and from headends such as described in EN 60728-5. Specifications from the transmission standard ETSI TS 102 034 are taken into account where applicable. The content of the data streams can be digital video, audio or other digital data. This Technical Report describes the necessary characteristics and parameters of equipment such as IP gateways or IP interfaces on equipment at the input of headends (Figure 1) as well as at the output of headends (Figure 2). Equipment at the input of headends can be either IP gateways which enable the connection to a DVB ASI headend infrastructure according EN 50083-9 or, in the case of modular headend systems can also be single equipment with IP interfaces such as DVB modulators, transcoders, multiplexers and FM radio processors as shown in Figure 1. Edge devices are also covered by this technical report.
