The Messenger Veta Receiver Decoder (MVRD) is a companion product to Cobham’s Encoders and
Transmitters providing the highest Video Quality with Ultra-Low Latency and Fast Recovery essential for
Wireless coverage of Real-Time events such as Sports and Surveillance Applications. The MVRD combines
all the features and capabilities of Cobham’s Messenger 2 AVC H.264 HD/SD Decoder with the unique SD
capabilities of Cobham’s MPEG-2/4 SD Veta Receiver. This includes end to end system-level latencies
down to ~44 mS when used with Cobham’s Messenger 2 or Veta Encoders/Transmitters.
The MVRD supports direct RF input of standard DVB-T 2K carriers with bandwidths of 6, 7, or 8 MHz.
Additionally, optional VETA 1.25 MHz or 2.5 MHz RF bandwidths with 400 carriers that allow both
increased reception range and larger quantity of simultaneous Audio/Video links to operate in the same
frequency band. The wider bandwidths provide greater throughput that allow the system to transfer the
highest quality Video. The standard MVRD is supplied with Dual-Diversity inputs and internal RF Block
Down Converters (BDCs). The MVRD’s Maximal Ratio Diversity Combiner provides optimum reception in
difficult fading and multipath environments. Additionally, the Diversity combining can provide up to 2.5
dB in link performance, increasing the receiver’s sensitivity to -97.5 dBm at 8 MHz bandwidth!

MVRD Block Diagram
HD & SD AVC H.264 Baseline profile decoding is provided with certain additions and exclusions as described in the
Specification section below including interlaced support. AVC H.264 decoding with resolutions from SD up to 1920
x1080, frame rates to 60 frames per second, with progressive or interlaced formats, CBR with down to 45 mS delay
when encoded with a Cobham’s AVC encoder. Additionally, with Cobham’s AVC Encoders, Instantaneous Decoder
Refresh or re-lock can occur on slice boundaries providing the fastest recovery from corrupted streams. Both Frame
and Field based Decoding is supported.
The MVRD also includes an optimal Internal Low-Latency Audio/Video (SD Only) MPEG-2/4 Part 10 Decoder and
output circuits that provide composite Video and two Audio channels. Optional User Data extraction is available in
all Modes. Security of transmission is ensured by the use of Standard ABS encryption or, for greater security, the
optional AES 128 or 256 bit scrambling algorithms.
The MVRD includes both DVB-ASI and Ethernet ports for Transport Stream Input/Output (I/O). The system also
offers a choice of transport protocols with support for AVC/MPEG embedded within a MPEG-2 TS (ASI or IP) and
raw H.264 bit streams (IP Only). LAN based transport streams can be delivered with either UDP/IP or RTP/UDP/IP
Protocols. A compressed TS stream can be input from the DVB-ASI interface, and reformatted for IP Streaming and

Output at the same time that it is being locally decoded. The Decoder incorporates error resiliency features. In the
event of a damaged bit-stream, the Decoder can replace the corrupt slice with skips, and resume decoding at the
next NAL unit. Alternatively it can freeze the output until a new I-frame is received.
The Decoder can be set to tune both Video and Audio in two ways: Auto and Manual. In Auto mode the unit will
self acquire the First MPEG program in the transport stream and the first Audio PID listed in the PMT for that
Program.
In Manual mode, for Multiple Program Streams (MPTS), the program number can be selected. Within the selected
MPEG program, each of the Two Audio Processors can have an Audio PID from that program selected.
The MVRD can be controlled either through its Front Panel Control Interface or through its USB or LAN interfaces.
Additionally, it has Two LED Status Lights. One LED is for Input which if Green when the selected Input is OK
(present and valid for transport stream interfaces, and meets settable criteria). The second Red LED Status Light is
for Error Conditions.
