SmartStream PLUS Redundant IP Streaming
Tieline’s proprietary SmartStream PLUS IP technology ensures you’re always on the air. The codec
features dual Ethernet IP ports allowing two completely independent IP connections. There are three
levels to SmartStream PLUS IP streaming.
1. The codec can stream simultaneous redundant data streams from both Ethernet ports and
deliver seamless redundancy by switching back and forth, without loss of audio, from the
nominated primary data link to the backup link if one fails and then subsequently recovers.
Use IP links from two different IP network providers for optimal redundancy over mission
critical connections.
2. Second, when multiple redundant audio streams are sent, the decoding codec automatically
reconstructs audio into a single stream on a first packet arrived basis, to minimize program
latency and ensure audio integrity.
3. Third, SmartStream features automated jitter buffer management and Forward Error
