OVERVIEW

Built on the proven, award-winning Intraplex® IP Link codec technology, GatesAir’s Intraplex Ascent Media Gateway platform supports reliable and secure Cloud-enabled distribution of TV and radio programming with high-end features.

The Ascent Media Gateway is ideal for applications that require real-time distribution of UDP-based media over IP-based WANs or Microwave. This includes video programs for TV broadcast, and distribution of audio or FM/MPX signals to a large number of radio transmitter sites. This high-density solution reduces cost and provides a path for convergence of IT and broadcast infrastructure.

Product Details

The Ascent platform continues the Intraplex tradition of reliable distribution with the Media Gateway over IP application. The platform provides a scalable, cloud-enabled solution for the distribution of video and audio signals with enhanced reliability and security with SRT (Secure Reliable Transport) protocol and Intraplex StreamSplicing®.

SRT is an open-source protocol that provides low-latency, reliable and secure streaming of video and audio data. The added capability of StreamSplicing over SRT provides enhanced reliability and security over multiple diverse networks. For uni-directional unicast network (i.e. STL Microwave), the reliability is accomplished using SMPTE-2022-2 and SMPTE 2022-7 “hitless” packet protection using FEC and a dual-WAN-networks scheme.

When using SRT on full-duplex links, the packet loss protection is provided using a built-in, real-time re-transmission scheme, added via Intraplex StreamSplicing technology with diverse WAN links. The security of the content is handled by the built-in AES-128/256 payload encryption.

Ascent is built on Commercial-Off- The-Shelf (COTS) x86 architecture to leverage the scalability and cost of the technology. It is available as a 1RU (single PSU) or 2RU (dual PSU, FANs) branded hardware server and as a software-only option.
