4K Carrier Mode
The 4K HIGH-THROUGHPUT OPTION enables user-selectable options to set bandwidths from 6 MHz to
16 MHz and to double the throughput of our standard M2T (Up to 63 Mbps!). In 2K carrier mode the
system would need to operate in 64-QAM to support dual program/video operations. Using 4K carriers
and the 16 MHz bandwidth, the link can support dual program/video HD operation using 16 QAM. This
increases link robustness and provides an additional 13.5 dB of gain with a link margin increase greater
than 4.7 x in operating range! for the same throughput rate in a standard HD MPEG-2 DVB-T system!
With the 4 K HIGH-THROUGHPUT OPTION you can run with fully DVB-T compliant 2K carriers and
bandwidths of 6, 7, or 8 MHz. When you switch to 4K carriers you can select 12, 14 or 16 MHz
bandwidth.
LAN/IP Port
The M2ECHPT contain a 10/100BaseT LAN interface that can be used both for Control & Status
monitoring and for Transport Stream (TS) streaming in and out of the device. The IP address can be
assigned automatically via a DHCP server or assigned a Static IP address. Control & Status monitoring is
accomplished via a WEB browser application. TSs can be sent out or in via UDP/IP or RTP/UDP/IP
transfer protocols.
3D Support
3D is a very new area in the Broadcast industry. From a content collection standpoint it is normally
accomplished with two separate cameras that are GEN-LOCKED together outputting two separate
Video signals.
AES-C Scrambling
The AES-C Scrambling option can be used to add security to your data transmission. The system
scrambles the payload portion of the TS packets. Only the TS header remains unscrambled to
enable operation with standard DVB-T receivers. The 128 bit-scrambling key is entered through the
M2ECHPT's control interface. The user can enable or disable the scrambling as well as choosing if
the key is stored within the Tx or not via Cobham's LAN WEB Page GUI. Encryption on/off is also
available from the local control panel.
