BN880
High-performance ST2110 IP gateway for multi-channel UHD and HD broadcast workflows.
Description
The Bluebell BN880 Series ST 2110 gateways offer advanced multi-channel conversion between SDI and ST2110 IP, catering to modern broadcast workflows with precision and efficiency. Available in two primary variants — 2-channel for 12G-SDI and 4-channel for 3G-SDI — each channel supports one video, four audio, and one ANC data flow. With the capability to handle up to 16 audio channels per flow and flexible audio re-mapping, the BN880 ensures unmatched versatility for complex signal transport requirements.
The BN880 series supports PTP (Precision Time Protocol), which enables accurate timing and synchronisation across devices, crucial for broadcast workflows. Optional PTP-synchronised genlock outputs can further enhance timing precision for video and audio signals, allowing secure and independent setup and management of the system separate from the main data streams.
Designed for high-performance environments, the BN880 features dual 25G (or 10G) Ethernet IP media ports with full support for ST 2022-7 hitless redundancy, ensuring reliable and uninterrupted signal transmission. The device offers flexible control and configuration options via NMOS or Ember+, as well as a published RESTful API for seamless integration into third-party control systems. Users can also utilise MN SET software or the USB-C port with BluebellConnect for quick and easy initial network configuration.
