Ascent offers two key differentiating factors for IP transport: an ability to manage many Secure Reliable Transport (SRT) streams on a centralized platform, and its integration of GatesAir’s unique Dynamic Stream Splicing (DSS) software. The latter diversifies SRT data across redundant networks, and adds protection against packet losses and network failures.
At IBC2019, GatesAir will demonstrate how the Ascent SRT Gateway supports reliable and encrypted transport of video content both in point-to-point and point-to-multipoint configurations. The addition of DSS software will support duplication of SRT streams with video and embedded audio over separate network paths, leveraging a single stream-splicing buffer for hitless protection against errors and failures.
The core Intraplex Ascent platform is available in two form factors, each of which supports up to 32 audio channels (AES3, AES67, analog). Both versions will be on display at IBC2019: a 1RU server, with configurable options for physical and AES67 channels; and a software-only solution that operates in a virtualized container. Ascent adds value to broadcasters by removing the need for many separate codecs and auxiliary hardware components at the originating studio or headend. This streamlined architecture frees multiple equipment racks in enterprise-level facilities, simplifying installation and systems management.
