Fast & reliable redundancy switching

You can depend on the compact 2:1 ProSwitch. The system monitors your MPEG-2 TS and seamlessly switches to a backup stream to maximize uptime. You can use this flexible 1-RU appliance for any architecture, including ASI-based headends and IP-centric networks.

Flexible architecture possibilities

Available with Gigabit Ethernet or ASI interfaces, the ProSwitch is suitable for any type of architecture: from widely deployed ASI-based headends to IP-centric networks. The switch is equipped with dual power supplies/plugs to maximize service availability and maintains service delivery via a smart and configurable bypass mechanism on the GbE and ASI interfaces — even in case of power failure.

Delay compensation capabilities

The ProSwitch offers delay-compensation capability by simultaneously analyzing delayed input streams (from several milliseconds to several seconds). If one input is detected as being corrupted, the unit compensates for the time difference and switches seamlessly to the other uncorrupted stream without any disturbance to end users. The typical application is network distribution redundancy.

Remote surveillance & configuration

The ProSwitch is equipped with a 100/1000 Base-T port for control and supervision. The unit can be supervised and configured remotely through any standard web browser, and provides a complete display of switching configurations, along with easy-to-read input/output status information, error-log data and bitrate graphics. The ProSwitch embeds an SNMP agent for centralized management applications.

Redundancy with ProSwitch

You'll get a fast, dense and reliable 2:1 MPEG-2 transport stream redundancy switch. Offering up to 16 2:1 IP switches or four 2:1 ASI switches in 1-RU, the high-density ProSwitch provides cost, power and space savings, helping operators to save on CAPEX and OPEX.

ProSwitch is ideal for all your redundancy needs

ATSC 3.0

Monitor and test models for this environment ensuring that your ATSC MPEG-2 TS is properly secured.

Network & product redundancy

Designed for automatic redundancy of 1+1 TS streams coming from two different paths handling different delays or coming from two different equipment.


Seamless switching for DVB-T/T2 terrestrial networks, by preserving the SFN structure of the incoming transport streams.

Turk Telekom leverages Harmonic’s ProSwitch for playout and redundancy. The ProSwitch monitors Turk Telekom’s MPEG-2 TS and seamlessly switches to a backup stream to maximize uptime. This ensures a flawless viewing experience for viewers, without minimal latency.
