OM 11 0648 Transmodulator 6x DVB-T/T2/C - 8x QAM/COFDM + 4 CI
Category : Micro Headend
The OM 11 0648 is a micro headend which can transmodulate 6 DVB-T/T2/C channels into 8 DVB-C (QAM) or 8 DVB-T (COFDM) channels. As it comes with 4 CI slots, it is perfectly suited for the central decryption of pay-tv services. There is also the possibility to create a multiplex before the CI slots allowing the user to combine services from different channels but to decrypt them by only one smartcard, hereby guaranteeing the efficient usage of professional CAMs. Additionally the OM 11 supports the deletion of unwanted services from a channel and enables the reduction of output channels by using the output multiplex functionality. As a transport stream, external video content can be fed in via USB or the LAN connection.
- Transmodulator of 6 DVB-T/T2/C channels to 8 DVB-C or DVB-T channels
- Integrated switch matrix reduces installation effort. Parallel insertion of DVB-T/T2 and DVB-C possible (Input 1 -> Tuner 1...2 / Input 2 -> Tuner 1...6 / Input 3 -> Tuner 3....6)
- 4 CI slots for central decryption
- PID remapping allows setting of static service PIDs at the output. It is no longer necessary for the TV set to make a scan if there is any transponder modification at the input
- LCN / NIT processing
- Multiplex functionality at the input and output
- USB-interface to feed in any video content
- Programming via web interface
- Integrated DHCP server enables an automatic connection to a PC
- Smartphone and tablet access via Bluetooth
