Gateway-4 Ideal for Remotes and STLs
Introducing Tieline’s New Generation 4 Channel Codec
The Gateway-4 is a powerful DSP-based 1RU IP codec designed for live remote broadcasting applications, as well as STLs or SSL links. The Gateway-4 also includes support for AES67, ST 2110-30, AES3 and analog I/O as standard, and an optional WheatNet-IP card. The Gateway-4 supersedes and replaces the popular Merlin and Genie STL audio codecs. It supports 4 full-duplex audio channels in 1RU to expand channel density by one when compared with these codecs.
The Gateway-4 is designed for solutions requiring up to 4 audio streaming channels with advanced redundancy features and remote configuration and control. It supports 4 full-duplex audio channels* in 1RU and is backward compatible with all Tieline IP codecs. The Gateway-4 provides two stereo connections, or one stereo and two mono connections, or up to 4 mono connections. The new generation Gateway-4 delivers best-in-class DSP-based reliability and performance for mission critical broadcast streaming applications. It is ideal for:
- Remote broadcast applications.
- Studio-to-Transmitter Links (STLs)
- Studio-to-Studio Links (SSLs)
For larger networks the Gateway-4 is ideal for transmitter sites, remote trucks or rack-mounted remote kits. For affiliates and smaller stations it can be used to transport studio-to-studio links, or a stereo studio-to-transmitter link signal plus another stereo connection, or dual mono connections for remotes. The addition of the Gateway-4 codec to the Gateway codec family delivers a codec designed for streaming solutions requiring between 1 and 4 channels of audio. Customers with higher channel requirements will gravitate towards the Gateway-8/16 multi-channel codec. The Gateway-4 perfectly complements the Gateway-8/16 codec, which has increased capacity of between 8 and 16 channels of IP audio, depending on the channel configuration purchased.
Gateway-4 – ideal for remotes…
Gateway-4 is ideal for remotes, and with 4 channels has increased capacity when compared to its predecessor the Merlin codec. This means it can support up to four simultaneous full-duplex mono remote connections.
The Gateway-4 is also ideal for connecting to the Tieline ViA codec, which simultaneously supports full-duplex stereo for program audio, plus a separate full-duplex mono IFB communications channel. Plus, the Gateway-4 will still have capacity for an additional mono connection if required.
Rock Solid STLs Featuring Multiple Layers of Redundancy…
The Gateway-4 delivers hitless packet switching using SmartStream PLUS redundant streaming, plus bandwidth aggregation using Fuse-IP technologies over internet connections. It features dual internal power supplies, dual LAN ports and dual AoIP ports. Automated network failure detection provides auto switching to a backup IP connection. The codec can automatically switch between 4 backup audio sources to maintain program output at transmitter sites. An optional Gateway Euro ISDN module can also be purchased for use with the Gateway-4. This allows the codec to integrate with legacy ISDN network infrastructure for primary or backup connections as required.
The Gateway-4 is also capable of multicasting, or multi-unicasting to up to 20 endpoints over IP.
Interoperability and Remote Control
Its feature-rich and compact design is interoperable with all Tieline IP codecs and compatible over SIP with all EBU N/ACIP Tech 3326 and 3368 compliant codecs and devices. Gateway-4 is fully optioned for today’s AoIP networks with support for AES67, ST 2110-30, and an optional WheatNet-IP card.
The Gateway codec family is configurable through an embedded HTML5 Toolbox Web-GUI interface and is also fully controllable using Tieline’s Cloud Codec Controller.
