Redundancy (Award winning)
Appear TV's intelligent redundancy software provides seamless integration between broadcast equipment and IP networks. The software is unique in being the only solution in the IP television market to take a holistic view of operation and network management. Redundancy configurations are simplified and automated, and operational routines are significantly reduced.

Appear TV's holistic approach is built upon a single software core capable of handling failures on both inputs and outputs. Appear TV's redundancy offers operators using IP for video distribution significant quality of service benefits and improved network efficiency. The system provides automatic backup in case of service stream failure on an operator's network, without requiring complex control software.

IP Output Redundancy
The IP output redundancy system presents a network with multiple sources from which it is possible to obtain the same service.

IP Input Redundancy
IP Input redundancy is designed to monitor failures external to Appear TV systems that may be indicated by link loss or the absence of a bitrate. The Appear TV chassis is configured with two IP input modules, one configured to serve as the main module, and the other as backup. In the event of input source failure, the IP input source is switched automatically.

Internal Redundancy
The DC1000 chassis provides an advanced, self-contained, input redundancy solution. The system is based upon 1+1 redundancy of the input module, switch module and backplane. Decoders can choose to receive configuration information from either the Master MMI or, should failure occur, from the slave MMI. Switching between the redundant input and backplane will be handled individually per decoder module based on active alarms on the modules.

IP Output Redundancy

• Provides unmatched service availability
• Rapid switching
• Utilizes general level 3 IP - routing protocols to perform the switching (or signal selection)
• Can switch an entire port or just one service (SPTS)
• Minimal network setup required
• Redundancy structure supports multiple site distribution
