Appear TV announced the launch of the industry’s most advanced IP seamless switching technology across its range of head-ends.
This new switch performs seamless switching, where two independent multicast networks rings are monitored for packet loss and switched to ensure the output is the better of the two.
This is enhanced with new functionality that monitors both networks simultaneously to ”reconstruct” the original data on the basis that the two networks are independent and will therefore not be subject to the same degradations, such as packet loss, at exactly the same time.
Additionally the Appear TV advanced “packet reconstruction” technique can enable operators to reduce the overhead for FEC while maintaining robust transmission QoS. This new technique is especially good news for networks suffering lengthy burst errors which are not handled efficiently by FEC but are by this new solution.
