The 7880DM-VSB is a complete hardware-based solution for demodulating digital terrestrial 8VSB signals. The 7880DM-VSB has one demodulator enabled by default and is software upgradeable to utilize the four built-in demodulators.
The 7880DM-VSB is hardware equipped with 4x RF inputs, 2x ASI ports (configurable as inputs or outputs) and one RJ-45 IP port.
Built with a modular form-factor, along with multiple inputs and multiple demodulators per card, the 7880DM-VSB represents one of the highest density and most flexible solutions in the industry. With ASI and IP interfaces, the 7880DM-VSB provides an ideal solution for turnaround, transcoding, transporting, monitoring or other applications where the received signal remains in the compressed domain. For baseband output, the demodulator may be coupled with an Evertz decoder module, providing a full receiver solution.
Monitoring parameters such as demodulator lock, MER, BER, packet errors and TR101-PR errors present a convenient solution for broadcasters and cable companies who wish to not only receive but also to remotely monitor signal quality.
In addition to an on-board web interface, the 7880DM-VSB is VistaLINK® PRO PRO-capable, offering remote monitoring, control and configuration capabilities via Simple Network Management Protocol (SNMP). This offers the flexibility to manage operations, including signal monitoring and module configuration from an SNMP-capable NMS. Intuitive local and remote control panels are also available for full control of multiple units (optional).
Features
- Quad 8VSB tuners with tuning capabilities of pre-stored physical channels (software-enabled)
- Supports onboard input auto-failover between various inputs including RF, ASI or IP inputs
- SMPTE ST 2022-1 and -2 compliant multiple TSoIP outputs per tuner
- Signal quality monitoring, including MER, BER and TR101-P1 errors
