Messenger 2 Transmitter Enhanced (M2TE) Key System Features above. All of this is included in a smaller housing (8.6 cu inches. Key features include optional Dual Audio/Video/Data processing with end to end system-level latencies of down to ~44 mS when used with Cobham Receiver/Decoders. The Ultra-low system latency greatly enhances real-time operating when the link is used in time critical situations like piloting Unmanned Aerial Vehicles (UAVs) or Unmanned Ground Vehicles (UGVs) or in threat response. Dual video processing enables 3D content collection which provides depth perception and...

Messenger 2 Transmitter Enhanced (M2TE) Our Messenger Receivers include an option for Spatial Maximal Ratio Pre-Detect Diversity Combining to combat multipath reflections found in indoor/urban environments. Cobham’s Messenger six or eight channel receivers with associated Messenger Antenna Arrays (MAAs) provide wide reception range without the hassle and cost of an auto tracking antenna system. The Messenger series Tx/Rx products provide a robust wireless link that is effective against the multipath interference experienced by analog systems and provides reliable data transmission in the...

Messenger 2 Transmitter Enhanced (M2TE) The OFDM scheme works by splitting the digital data stream into a large number of slower digital streams each of which digitally modulate a set of closely spaced adjacent carrier frequencies. COFDM goes a step further by using a “Coding” scheme to map the data onto the multiple carriers in a way that maximizes recovery from link errors. This coding includes Forward Error Correction with Convolution Interleaves’ and Reed Solomon encoding along with careful distribution of the data onto the multiple carriers. COBHAM has chosen to use 2K carrier in which...

Messenger 2 Transmitter Enhanced (M2TE) Content Collection Format The encoder maintains a frame by frame synchronization as it goes through its processing. AES Scrambling The AES 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 DVBT receivers. The 128 bit-scrambling key is entered through the M2TE’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...

Messenger 2 Transmitter Enhanced (M2TE) The Picture Timing SEI messages allow each Video frame to be assigned a time value. This time can represent time of origin, capture or alternative ideal display. As such, it can be used to navigate to a frame with a particular time. The H.264 format, specified in ISO/IEC 14496-10 provides for an optional time stamp to be defined in the Supplemental Enhanced Information (SEI) message. The picture timing SEI message (pic_timing) specified HH:MM:SS:FF IAW RP 0604 page 5. Additionally, the standard allows for user data to be associated with a particular...

Messenger 2 Transmitter Enhanced (M2TE) RTP (Real-time Transport Protocol) operates at the Application layer (OSI model) and it relies on UDP at the transport layer to transport real-time multimedia data across networks that use the Internet Protocol (IP). UDP is preferable to the Transmission Control Protocol (TCP) for real-time applications because it offers low-latency transport across IP networks. Control Local – Easy to use local control and status panel allows up to 20 user-defined operating modes covering most programmable parameters including Center Frequency, 4 Range Settings...
