Las Vegas (USA), April 24th, 2017 – TeamCast, the global market leader in advanced solutions for Digital Terrestrial and Satellite Transmission, releases at NAB Show 2017 the new VORTEX II product dedicated to ATSC 1.0 and 3.0 networks.
VORTEX II comes as a ready-to-use stand-alone rack modulator/exciter, specifically designed to be integrated inside new and existing DTV transmitters. Its DualCast modulation capability meets Broadcaster’s requirements for smooth and straightforward transition from ATSC 1.0 and ATSC 3.0 using the same hardware platform. In ATSC 1.0, VORTEX II integrates unique and unmatched Precorrection techniques to compensate “Very-Sharp Tuned” filter nonlinearities. Obviously with the current FCC repack it is expected that digital adjacent channel cases will become more of a requirement to accommodate all US broadcasters. Thus, more complex and “Very-Sharp Tuned” filters will be required and will have to be properly pre-corrected by the modulator.
VORTEX II integrates the very latest state-of-the-art ATSC 3.0 modulation core.
Compared with the first generation, ATSC 3.0 standard is considered as a “revolution” rather an evolution. Several specific requirements such as the use of IP interfaces rather TS/ASI, the implementation of complex input IP packet buffer and multi-layers PLP (Physical Layer Pipes) frame builder and the possibility for future waveform support (thanks to the bootstrap signalling) has conducted TeamCast’s engineers to completely revised the modulator hardware implementation for a more powerful and IP centric design architecture.
“We believe that VORTEX II allows TV Broadcasters to invest in a longer term and future-proof transmitter Exciter solution, in a context of major transitions foreseen for the terrestrial Broadcast environment such as the introduction of the new ATSC 3.0 standard and the TV spectrum repacking plan” says Eric Pinson, Head of the Technology Business Unit at TeamCast.
VORTEX comes as a very innovative solution for the TV exciter market, bringing several key features to ease the integration within transmitter design and to achieve high level RF performance. This includes state-of-the-art Digital Adaptive Pre-correction, an Automatic Gain Control (AGC) process to ensure the correct output power stability and monitoring of key transmitting power measurements such as Forward Transmitted Power and Reflected Power levels.
“With ATSC 3.0, we enter into a new era of Terrestrial Broadcast where linear TV will give the floor to more open and diversified IP based multimedia services. This revolution also concerns the DTV modulator and we had to revise our traditional way of designing a DTV modulator toward a more future proof, powerful and IP centric modulator design. With VORTEX II we are very proud to have taken up this challenge and this confirms our leadership on this market.” Adds Eric.
VORTEX will be demonstrated at NAB show 2017 on TeamCast’s booth SU6505.
