DLR has awarded a contract to SHM Broadcast GmbH –T-VIPS’ German
Business Partner, to supply T-VIPS TVG420 Video Gateway Technology
as part of a low-latency video link between the DLR Columbus Control
Center, the NASA Johnson Space Centre, Houston, TX and the Russian
Space Centre, Moscow, from where craft docking is ultimately
controlled
Oslo, Norway -- T-VIPS AS, a Norwegian technology company that
designs, builds and supplies world-leading solutions for
contribution & distribution of broadcast quality video signals over
IP networks, today announces that its TVG420 IP Video gateway has
been chosen by DLR, the German Aerospace Center, to play a vital
role distributing video from the International Space Station to the
Russian Space Centre in Moscow. This video is monitored at the
Russian Space Centre to ensure the safe docking of the Soyuz,
Progress and Automated Transfer Vehicles with the International
Space Station. |

“For the video to be
a useful tool in controlling the docking of spacecraft with the
International Space Station, it’s crucial that latency is minimized.
To do this we designed a system architecture that only required
encoding/decoding at the ISS and at the Russian Space Centre, in
addition we chose the proven technology of MPEG-2 as it provided the
best combination of image quality and low latency,” says Ground
Operations Manager, Thomas Müller of DLR.
The video of spacecraft docking with the International Space Station
(ISS) is encoded to MPEG-2 at the ISS, down-linked to a ground
station in the USA and distributed over fibre to the Johnson Space
Centre in Houston, TX. At Houston a T-VIPS TVG420 encapsulates the
MPEG-2 video stream into IP and distributes it to the DLR German
Space Operation Center (GSOC) near Munich, from where it is
distributed onwards to the Russian Space Centre. At the Moscow
Mission Control Centre the IP encapsulated video is received by a
T-VIPS TVG420 and converted back into MPEG-2 ASI format. Crucial
features of the TVG420 are advanced de-jittering and Forward Error
Correction functionality, which ensure that Moscow receives a
perfect signal, in spite of network jitter and packet loss.
“The T-VIPS420 Video Gateway brought to us by SHM Broadcast, was the
only solution that provided both the functionality and low-latency
we required in a field tested solution. I’m sure it’s obvious to all
how important it is that the docking of a spacecraft with a manned
space station is controlled properly, for such an important task the
combination of functionality, low-latency and the proven reliability
of the T-VIPS420 solution made it the only possible choice,”
concluded Felix Lang, Video Engineer, DLR.
“We were aware that DLR required a video transport solution that
combined low-latency with high reliability and knew that the T-VIPS
TVG420 solution was the best solution for this important
application,” says Michael Preisser, Managing Director and Partner,
SHM Broadcast GmbH. “We organized a demonstration for DLR’s
technical team of the T-VIPS solution, after which we worked with
the DLR and T-VIPS technical teams to enhance the TVG420 to meet
DLR’s demanding specifications. This project was completed and
tested successfully in a short time-frame at which point DLR awarded
us the contract to provide the T-VIPS intelligent video transport
solution. I look forward to working with T-VIPS to ensure that we
can provide DLR with innovative video transport solutions to meet
any future requirements.”
“It’s a great honour for our equipment to be chosen for such an
important application,” says Johnny Dolvik, CEO, T-VIPS. “We often
talk about mission critical video applications, this is perhaps one
time where the timely arrival of high-quality video truly lives up
to this description. The choice of our solution by DLR sends a
message to all broadcast and video professionals that IP video
distribution is now suitable for all video transport tasks, however
critical.”
