TxEdge T2V2
Local T2 adapter
TxEdge T2V2 is standard-based solution that enables the delivery of DVB-T2 regional or local services over SFN networks while saving operating OPEX by optimizing the distribution network bandwidth.
Highlights
Deployed in the DVB-T2 world’s largest roll-out
In 2011, MULTICHOICE, the leading multichannel digital television operator across the African continent, has selected the TxEdge for the deployment of the world’s largest DVB-T2 network over Pan-African countries with a total bouquet of more than 50 different channels over 15 countries. Since then, it has been deployed by leading TV operators across Africa, Asia and Europe.
Regional content insertion using PLP substiution
The TxEdge is taking benefit from the multiple PLP technology to build the DVB-T2 regional multiplex at the DVB-T2 transmitter sites. Receiving national and regional T2MI streams composed of several PLPs, the TxEdge can substitute in the national T2-MI stream some PLPs from the regional PLPs to update with local content. The insertion is performed in a deterministic manner to enable SFN broadcasting
Regional content insertion using PLP aggregation
The PLP aggregation technology is an advanced and flexible regional content insertion solution that behaves as a PLP remultiplexer. It allows aggregating one or several PLPs between the national and regional T2-MI stream to build the regional multiplex.
Bandwidth optimization to reduce annual OPEX
The use of Multi-PLP architecture and PLP Substitution brings unmatched flexibility to the Network Operator and allowing a drastic reduction of the operational costs; all common TV content (national or international) being delivered only once to save the distribution network bandwidth.
Regional Emergency Warning Services (rEWS)
rEWS is a receiver-agnostic system providing video-based emergency warnings on a regional basis of dangerous weather events and natural disasters for DVB-T2 networks. It allows normal programming to be interrupted to play out the emergency alert, replacing all normal A/V transport stream components with the emergency content.
High Density chassis
The TxEdge can be embedded in the ENENSYS high density chassis to allow the generation of 6 different regional DTT multiplex. It can also be combined with ASIIPGuard or IPGuardV3 products
