CommunicAsia 2008

Time flies! The CommunicAsia / BroadcastAsia 2008 is already behind us!

We are back to the office and ready to tackle all the good opportunities that we found on the show floor.

For those who couldn't visit us on the booth in Singapore, here are some pictures that will give you a good idea of the great demos we had there:

Overall Demonstration :

All components of a Broadcast ecosystem were demonstrated on the booth:

- We had a Canon HD camera with HD-SDI output.

- Our TS process tool Village Flow was used to encode the HD channel and stream it over IP.

- The TSoIP HD service was displayed on an HD LCD panel thanks to a Motorola IP Set Top Box.

- The MuxXpert was multiplexing several TS streams to several outputs.

- The DekTec modulation card were used to generate an RF signal to a DVB-T and a DVB-S STB.

- We also had the StreamXpert Analyzing software.

- and also the the recording software DtGrabber+ and the monitoring tool VI Monitor.

- Finally, we had the new DekTec Power over Ethernet adapter for remote analyzing.

Here is the graphic that explains all that:

Village Flow software:

Here we were using Village Flow for the real time encoding of 1 HD video stream coming from an HD camera and also of 4 SD video streams coming from the same camera and from some DVD players. 1 server was used for the HD channel and another one for the 4 SD channels. All channels were then streamed over IP on the network.

MuxXpert:

The MuxXpert (DTC-700) was giving it's best here, taking the HD stream and the SD ones, multiplexing them in 3 different outputs:

- One ASI output using the DTA-160 card which has both Ethernet and ASI interfaces.

- One DVB-T RF output thanks to the DTA-115. This one was connected to the 2 DVB-T set top boxes installed on the booth.

- One DVB-S (QPSK) RF output thanks to the DTA-107 which was as you can guess connected to a DVB-S Satellite set top box.

StreamXpert and RFXpert:

The StreamXpert (DTC-320) was decoding and analyzing virtually all the streams on the booth:

- With the DTU-245, it could take any ASI in.

- With the new DTE-3120 we had a remote, over IP access to the ASI stream. (read below)

- With the DTU-235 even an DVB-T RF signal was analyzed. And that's also with the same DTU-235 that we were doing an RF analysis thanks to the RFXpert software.

Monitoring:

Monitoring was not left aside:

- DtGrabber+ (DTC-325) which allows to do advanced recordings of TS streams from DekTec input interfaces, was constantly backing up our videos.

- VI Monitor was also here to monitor all our streams and make sure that no DVB errors were being broadcasted. VIMon can send standard SNMP traps when errors are detected in the stream.

PoE Adapter, the new DTE-3120

The brand new Power over Ethernet adapter from DekTec was demonstrated For the first time in Asia at the CommunicAsia 2008.

Promised to a great success, this tool of a new genre allows monitoring your ASI remotely. You can for example keep this device in the server room plugged on the ASI output of all your encoders, IRDs and other Broadcast equipment and access it remotely to check whether all these equipments are functioning correctly.

Another use of the DTE is a stand-alone converter that can take any ASI in and send it out on the network as a TSoIP multicast stream.

You can check more details on the new DTE in the news published previously on this same page.

DekTec Pioneers Revolutionary Approach to Networked Digital-Video Adapters

DekTec is using NAB to unveil what it believes are the first ever Transport Stream over IP (TSoIP) to Digital Video converters to feature Power over Gigabit Ethernet technology, giving new and unprecedented flexibility to expand server I/O. The first two products in the family are being launched at NAB, and convert DVB-ASI streams to and from TSoIP for transmission on Gigabit Ethernet networks.

DekTec's new networked digital-video adapters

The units can be used either as compact autonomous gateways, or as remote I/O devices for server-based data inserters, stream servers, multiplexers and similar systems. The new DekTec DTE-31xx family of TSoIP adapters can interface MPEG-2 transport streams with PC-based applications via an Ethernet network, giving much greater flexibility to system architecture. As a result, content capture and streaming devices can be located further from the central server, and the number of I/O ports is no longer constrained by the availability of PCI slots on the server.

Up to 14 modules can be installed in 3U 19" rack space using the DekTec rack-mountable rail, or the units can be mounted on a DIN rail directly on a wall. The networked I/O architecture obsoletes the need for device drivers, creating independence of the server's Operating System.

A significant innovation in the DekTec DTE-31xx family is support for Power over Ethernet (PoE). When used with a PoE compatible network, the TSoIP converters do not require a separate power feed, as they can draw their power from the Ethernet network. A power jack is still offered, however, where PoE is not available. Initially, DekTec is releasing two products, the DTE-3100 for conversion of incoming TSoIP streams to a DVB-ASI output, and the DTE-3120 for transmitting incoming DVB-ASI streams over an Ethernet network using TSoIP.

The DTE-3100 accepts unicast, broadcast and multicast streams over its Gigabit-Ethernet port, and converts the TSoIP stream to DVB-ASI. Key features include de-encapsulation of UDP or RTP, accurate timing reconstruction using innovative algorithms to overcome IP jitter, as well as error correction according to SMPTE-2022-1.

Conversely, the DTE-3120 accepts DVB-ASI streams for transmission as TSoIP via Gigabit Ethernet. The converter generates unicast, broadcast and multicast streams using encapsulation in UDP or RTP and can optionally add SMPTE 2022-1 error-correction packets. A special feature of the DTE-3120 is a loop-through with fail-over relays for input-to-output connection in the event of power failure.

Both devices support SNMP management, and have a web-based user interface for configuration purposes, as well as retrieving status information and performance statistics. An LCD status display with user-programmable identifier is also offered on each unit.
