Tieline Introduces Gateway-4 IP Codec

Suitable for remote broadcast, STL and SSL applications

Tieline Gateway-4, audio codecsTieline has added another IP audio codec to its lineup called the Gateway-4, which it expects to begin shipping by the end of next month.

It described it as “a powerful DSP-based 1RU IP codec designed for live remote broadcasting applications, as well as STL or SSL links,” the manufacturer stated in its announcement.

“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 replaces the company’s Merlin and Genie STL audio codecs; it supports four full-duplex audio channels in 1RU to expand channel density by one compared with the older models. VP Sales APAC/EMEA Charlie Gawley said it is suitable for mission-critical broadcast applications requiring two to four audio streaming channels. Those who need more channels can choose the Gateway-8/16 multichannel codec, another recent introduction that replaced the Merlin Plus and Genie Distribution.

The new codec provides two stereo connections, or one stereo and two mono connections, or up to four mono full-duplex connections. Tieline said it also supports multiple unicasting to up to 20 endpoints and multicasting.

“For larger networks, the Gateway-4 is ideal for transmitter sites, remote trucks or rack-mounted remote kits,” Tieline said. “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.”

Features include hitless packet switching using SmartStream Plus redundant streaming, and bandwidth aggregation using Fuse-IP technologies over internet connections; dual internal power supplies, dual LAN ports and dual AoIP ports; and an optional Gateway Euro ISDN module to integrate with legacy ISDN network infrastructure for primary or backup connections.

It is interoperable with other Tieline IP codecs and compatible over SIP with EBU N/ACIP Tech 3326 and 3368 compliant codecs and devices.

It is configurable through an embedded HTML5 Toolbox Web-GUI interface and is controllable using Tieline’s Cloud Codec Controller.
