T2Gateway DTH for HDc
Single Illumination DVB-T2 Gateway
T2Gateway DTH is ENENSYS DVB-T2 Gateway for DTH in the OneBeam for DVB-T2 solution. Running at the head-end, the T2Gateway DTH is the central body of the DVB-T2 network, providing in-band control and signaling to remote T2EdgeDTH. It defines the whole T2 configuration as a regular DVB-T2 Gateway and generates the SFN timestamp information. It describes the DTH services to map to the different PLP and inserts the in-band control information as well the synchronization information within the DTH stream without any impact for DTH consumer.
Applications
- Use existing DTH services to build T2 multiplex
- Backup DTT transmission site with DTH stream
- Simultaneous FTA DTT and Pay TV DTH services
- Covering DTT ‘black spots’ with DTH services
- Regionalization support
Key points
- Bandwidth optimization to reduce annual OPEX
- Very fast Return On Investment (ROI)
