Powerful Solutions for DTT
Appear TV offers innovative, flexible and compact head-ends for digital terrestrial television operators, which includes compression, statistical multiplexing, DVB-T/T2 adaptation and redundant distribution to transmitter sites. Appear TV has adopted a modular approach that maximizes the potential of the broadcast system through unprecedented integration and density.
A wide selection of input, processing, and output modules enable systems that are tailor made to customer specifications. Virtually any broadcast system configuration is possible.
- IP, ASI, DVB-S/S2/S2X/T/T2/C, ISDB-T, 8-VSB and analog RF input options
- High-quality encoders and transcoders, complete with integrated statistical multiplexing controller
- CSA/AES scrambling, audio leveling and EPG processing
- Multiplexing and advanced PSI/SI generation on all output modules
- Fully-featured DVB-T/T2 gateways with IP or ASI output
- High-density DVB-T/T2 IRDs for system monitoring
All Appear TV modules are integrated into a full featured and intuitive management interface with a strong focus on operational aspects such as simple deployment and ease of use, without sacrificing the ability to control and monitor on a deep level every aspect of the system. The high density and tight integration is backed by a comprehensive set of redundancy features, providing all the safety measures required to enable dense, highly integrated systems.
The integration of every part of the required head-end functionality into the Appear TV system provides a valuable single vendor responsibility scenario; simplifying logistics, removing integration issues between vendors and enabling comprehensive end-to-end support. However, Appear TV remains strongly committed to open standards and ensuring third party equipment compatibility.
Appear TV has integrated the gateway functionality for DVB-T2 into its system as an output module. The IP gateway can deliver 4 independent multi-PLP T2MI streams and the ASI gateway can deliver 2. Both the IP and ASI gateways have dual mirrored outputs. Full re-multiplexing and PSI/SI generation is supported on every PLP, making the T2MI gateway appear as a standard output in the system. The system comes with an intuitive drag-and-drop user interface for setting up output streams, and provides advanced assistance in calculating PLP parameters based on desired bit-rate and time-interleaving depth.
Appear TV IP based gateways can be fully synchronized, and all head-end components are provided with advanced redundancy options. Together with the unique Appear TV network redundancy feature, true seamless end-to-end protection between the head-end and transmitter sites is provided, with no single points of failure.
Appear TV DVB-T2 gateways further support a variety of models for regional content insertion in SFN networks, including bandwidth optimal solutions for satellite distribution using PLP replacement and local gateways with re-multiplexing.
