Aircaster AQT8 Transmodulators

Blonder Tongue Labs allows users to create custom IP and QAM channel lineups from any ATSC 1.0 off-air or QAM content source

Blonder Tongue Laboratories, Inc., a U.S.-based designer and manufacturer of telecommunications, fiber optic, video, and data delivery technologies, released the updated Aircaster AQT8 series of transmodulators —including the Aircaster AQT8-QAM/IP and Aircaster AQT8-IP — a comprehensive and flexible toolset to create custom IP and QAM channel lineups from any ATSC 1.0 off-air or QAM content source.Transmodulators

The solution is suitable for facilities looking to incorporate off-air video programming without paying additional retransmission fees for local cable or satellite services.

“Until now, off-air to digital rebroadcasting equipment have been single use or only offer one-to-one signal conversion. Creating new channel lineups as well as correcting channel metadata to be fully standards compliant has required a labyrinth of converters, splitters, amplifiers, and more,” said Ted Grauch, President and CEO of Blonder Tongue Laboratories. “The Aircaster AQT8 reimagines what off-air rebroadcasting equipment can do in a single compact unit, enabling custom lineups of up to 64 channels, accessible to thousands of residential homes in the case of service operators, or hundreds of rooms and TV sets for hospitality, institutional, and SMB use cases. It effortlessly creates and multiplexes a complete digital media service, while eliminating unnecessary fees and equipment.”

The Aircaster AQT8 transmodulators are suitable for any fiber optic or cable service operator or commercial property, including campuses, hospitals, hotels, and multi-dwelling units (MDUs), as well as video integrators with small- and medium-sized business (SMBs) customers. Requiring only one RU, the device can accept up to eight ATSC 1.0 off-air or QAM sources, and simultaneously output a series of either Single Program Transport Streams (SPTS) and/or Multi-Program Transport Stream (MPTS), creating both a custom IP feed and/or QAM transmissions.

Featuring an internal active splitter, the Aircaster AQT8 enables users to create a full lineup of up to 64 channels and distribute them to thousands of different locations across a facility, eliminating the need for countless digital converters, external splitters, and legacy one-to-one solutions.

Aircaster AQT8 transmodulators feature:

  • Pass Through Mode, which directly maps the demodulated RF port content in MPTS format to IP output
  • Encrypted QAM input and IP/QAM output allows for MPTS or SPTS formats while preserving the source MPEG tables (PAT, PMT, PSIP, VCT, and MGT)
  • Virtual channel mapping via a simple interface, where users can change the packet identifier (PID), program number short name, major/minor channel (PSIP), and overall channel lineup
  • Signal testing and GUI-based remote monitoring and control via any web browser to improve quality while reducing truck rolls
  • Emergency Alert System (EAS) control to override standard inputs and distribute an alert signal to an entire MDU facility
