ModulCast ATSC
ATSC 3.0 Modulation Board
ModulCast ATSC is an optimized and unique modulation board supporting ATSC 3.0 standard to design Terrestrial TV Transmitters. It meets manufacturers’ demands for a quick & straight-forward integration and made High Quality TV Transmitters to answer broadcasters’ quality requirements.
Highlights
ATSC 3.0 Standard
Based on Vortex II exciter experience, largely use across USA for powering ATSC market transition from version 1.0 to version 3.0 of the standard, ModulCast ATSC is a cost effective and optimized solution for ATSC 3.0 commercial roll out.
Up to 8 PLPs & 2 Subframes
To cover any commercial use case deployment, ModulCast ATSC manages up to 8 PLPs / 2 Subframes as well as MFN (Multi Frequency Network) and SFN (Single Frequency Network) system architecture.
Precorrection Process
ModulCast ATSC integrates two Non-Linear precorrection algorithms for a better adjustment of your Power Amplifier and broadcast a very high quality signal.
Automatic Gain Control
Based on its real-time power measurement probes, ModulCast ATSC can control and adjust your Transmitter output power: it simplifies your Power Amplifier Design without compromising on the RF output quality.
