Features
- IP encapsulator encapsulates IP packets into digital television MPEG Transport stream packets.
- IP encapsulator presents gateway between IP and digital televison networks. It is mandatory equipment in any digital television network (e.g. DVB-S,S2, DVB-T,T2, ATSC, ISDB etc) for provisioning data services.
- Add-on function of MD IPE is QoS allowing to manage data channel bitrates, set min (CIR), max (PIR) bitrates and priority. QoS main feature is to maximize bandwidth usage dynamically.
- In a case entire e.g. DVB channel is used solely for IP services, for example in a case of satellite internet, IPE connects directly to the modulator, most typically via DVB-ASI interface (IP interface is an option). In a case when data services are provided along with TV services IPE connects typically to multiplexer, again via DVB-ASI or IP interface.
- IP data, mainly file downloads, are much less time critical to be transmitted comparing to TV programming. Bandwidth of TV service fluctuates according to the content, part of broadcastcapacityremainsunused- filledbynullpackets.
- MD IPE encapsulator performs most critical functions, while BNMS provides management layer. One BNMS can control many IPEs. IPEs connectedtooneDigitalTVtransmissionpresent1 cluster. In case one of them fails traffic is automatically rerouted to next one.
- RMC - remote monitoring client is used to monitor traffic of IPE cluster, PID or datachannel and its overheads.RMCis a Java application, can be run at different operating systems.
- IPE as the core equipment of Digital TV Data platform interfaces to multiple other equipments and SW modules as described at figure bellow.
