Newtec... Streaming Up — DVB-S2 x2 (Equipment)

[SatBroadcasting(tm)] One of the largest European public broadcasters, Westdeutscher Rundfunk (WDR), has equipped its fleet with Newtec Satellite Modulators and is equipping its crucial DSNG broadcast truck, FÜ5 (Bocklemünd Fernsehübertragungswagen 5), with Newtec's DualFlow™ technology to provide support for ASI and IP-based operations.

WDR's installation of Newtec's DualFlow-enabled Azimuth Broadcast Satellite Modulators guarantees flexibility in its outside broadcast operations and simplifies the transition to full IP-based contribution. WDR's FÜ5 is primarily used for sports news gathering and the popular early morning "Morgenmagazin" program on ARD and Zweites Deutsches Fernsehen (ZDF). With Newtec's DualFlow and Newtec's Azimuth Broadcast Satellite Modulators installed, the capabilities of FÜ5 increase from dual DVB-S transport streams to dual DVB-S2 streams. FÜ5 will maintain compatibility with existing ASI infrastructure while providing support for IP-based operations, guaranteeing 100 percent tapeless workflow support including VoIP links to the studio and broadband web-surfing while on the road.

Newtec's DualFlow technology enables a progressive migration from a traditional ASI video satellite transmission network to an IP infrastructure, allowing WDR to migrate from DVB-S to DVB-S2 in the future without changing the infrastructure and equipment configuration. Newtec Azimuth equipment enabled with DualFlow technology delivers a compact and highly versatile solution for broadcasters seeking lower operational costs through highly efficient bandwidth use, together with backward compatibility and a future-proof design combining video and IP technologies. The Azimuth Broadcast Satellite Modulator (AZ110) with DualFlow is capable of transmitting two transport streams simultaneously in DVB-S2 Multistream mode, and it can interface with equipment or networks that carry transport streams over IP with the RTP or UDP protocols. DualFlow also provides the ability to transmit IP services (e.g., file transfers, VoIP, TCP services) and transport streams simultaneously, making mobile broadcast trucks and vans much more versatile and productive as online production units.
