## Summary description

Signal MOD/SIG-420 is a DVB-T modulator designed to convert audio/video input into a DVB-T RF broadcast signal. It serves integration of video sources into terrestrial DVB-T distribution systems, enabling multiplexing of content for transmission to DVB-T receivers. Typical uses include local TV distribution, hospitality systems, and headend installations.

## Long description

Signal MOD/SIG-420 is a DVB-T modulator that converts composite audio/video signals into a DVB-T RF broadcast stream suitable for integration with terrestrial distribution systems. Designed for headend installations and local distribution, the device accepts standard AV inputs and outputs a modulated COFDM signal on selectable UHF/VHF channels to be received by DVB-T tuners and set‑top boxes. The product is intended for professional and semi‑professional deployments such as hotels, campuses, apartment buildings, or small broadcast headends.
Advantages
The modulator provides reliable conversion from analog AV sources to a digital DVB-T RF output, supporting stable multiplexing into existing DVB-T networks. Its compact design and straightforward signal routing reduce installation complexity and rack space requirements. The unit is compatible with common DVB-T receivers and set-top boxes, enabling distribution of live video and audio across coaxial cable infrastructures without requiring IP network changes.
Suitable for (tasks / use cases)
 Local TV distribution in hotels, hospitals and residential buildings
 Headend systems for small cable or MATV networks
 Integration of CCTV or media players into DVB-T distribution
 Temporary event broadcasting where RF distribution to DVB-T tuners is required
When it may not be suitable
The MOD/SIG-420 is focused on converting AV inputs to DVB-T RF and is not a replacement for IP streaming encoders or advanced multiplexers with extensive service management. It does not provide features specific to DVB-T2, multicast IP distribution, or advanced conditional access systems. For installations that require DVB-T2 compatibility, encrypted pay-TV CAS, or direct IP streaming to OTT platforms, this device may not meet all requirements.
Key specifications
 Input types: analog audio and composite video (AV)
 Output type: DVB-T RF (COFDM) on selectable UHF/VHF channels
 Modulation: standard DVB-T COFDM parameters (channel bandwidth and guard intervals selectable per installation)
 Supported resolutions and audio formats: compatible with standard-definition composite sources
 Power and dimensions: compact form factor suitable for rack or shelf mounting (refer to official datasheet for exact physical dimensions and power consumption)
How to use
Connect the composite video and stereo audio outputs from your source device (such as a DVD player, camera, or media player) to the corresponding input connectors on the MOD/SIG-420. Configure the output channel, modulation parameters and multiplex settings according to your DVB-T network plan using the device controls or web/remote interface if available. Feed the RF output into the coaxial distribution network or directly to DVB-T receivers. Verify signal levels and channel tuning on representative DVB-T tuners to ensure proper reception across the distribution system.
What to consider before purchase
 Confirm that DVB-T (not DVB-T2) output meets the required receiver compatibility in your installation
 Check that your source devices provide compatible composite AV outputs or plan for appropriate converters
 Ensure available RF channel allocations and compliance with local broadcasting regulations
 Review the unit's physical size, mounting options and power requirements against available infrastructure
Usage recommendations
Place the modulator in a ventilated cabinet and use quality coaxial cabling and connectors to minimize signal loss. After initial setup, perform channel scans on multiple DVB-T receivers at different locations to confirm uniform coverage. For environments with multiple sources, label inputs and keep configuration documentation to simplify maintenance and future changes.
