Built on the proven, award-winning Intraplex® IP Link codec technology, GatesAir's Intraplex Ascent platform supports up to 32 audio channels with high-end features.

The scalability of Ascent makes it ideal for applications that require multiple channels of audio encoding and decoding at head-end sites. The high-density solution reduces cost and provides a path for convergence of IT and broadcast infrastructure. The interoperability between Ascent and IP Link codecs provides a complementary solution for remote contribution and distribution use cases.

Product Details

The Ascent platform continues the Intraplex tradition of providing an unprecedented level of reliability for audio over IP application. Built with enhanced network reliability and security in mind, Ascent supports the Dynamic Stream Splicing technology of IP Link codec, which provides “hitless” protection for packet losses using the combination of time and network diversity for packet transmission, and FEC.

To further enhance reliability and security, the platform supports the SRT protocol encapsulation. SRT (Secure Reliable Transport) is an open-source protocol that provides low-latency, reliable and secure streaming of audio and video data. The reliability in SRT is accomplished by a built-in packet re-transmission scheme; the security of streams is handled by the built-in AES-128/256 payload encryption.

In addition to “hitless” protection, like the IP Link codecs, the Ascent also supports automatic failover between different incoming streams or stored audio.

This combination of capabilities gives Intraplex codecs a market-leading position in STL over IP technology and unmatched network transport reliability.

Ascent supports both physical audio interfaces (AES3, Analog) and AES67 (AoIP), with a maximum of 16 full-duplex or a total of 32 channels (combination of encode and decode). Physical audio interfaces can be ordered as 4- or 8-channel cards, supporting both AES3 and analog audio signals.    The Ascent product is built on the Commercial-Off-The-Shelf (COTS) x86 architecture to leverage the scalability and cost of the technology. The product is available in a 1RU branded hardware server and as a software-only option.

The next generation of digital STL
Our challenge: to design a studio-to-transmitter link (STL) for your most demanding 950 MHz applications — one as reliable and robust as Intraplex® T1 and IP audio links. Digital STL manages much more than audio, so installation and configuration need to be straightforward, not a science project. Data should not be optional, requiring additional boxes and complexity. Your STL should be ready, out of the box, for AM, FM and HD Radio™, as well as future multimedia applications.

Earlier digital STLs were not designed for IP data transport. Adding IP data to them required optional modules and external add-ons, and many engineers working on HD Radio installations reported spending much time and money trying to eliminate glitches.

Our solution: HD Link™ is designed to manage all HD Radio™ transport scenarios, regardless of where you place your importer and exporter. Its two prioritized Ethernet paths give preference to HD Radio™ data over control and other LAN/WAN data. It supports both UDP and TCP, and even handles the switching of TCP return packets over asymmetric IP paths with plug-and-play simplicity.

HD Link offers RF power to spare, an integrated IP gateway with sophisticated data handling capabilities, and multiple channels of audio. The intuitive front panel and remote interfaces tap into the most complete feature set of any microwave STL, yet take less time to configure. It can even operate on both RF and IP simultaneously, and allows automatic backup of all services from one to the other.

Intraplex is broadcasting’s first choice for rock-solid, full-time operation of T1 STLs. With HD Link, you can now count on the same dependable performance, superior support and long-term value for your microwave links.

Intraplex® IPConnect is an IP networking gateway solution for fortification of mission-critical communication across wide area networks
IPConnect solves the problem of reliable transport across complex networks that traditionally suffer data loss through dropped packets. IPConnect provides an added layer of reliability for many types of IP traffic such as HD Radio, DAB/DAB+, or DRM by employing a combination of packet protection schemes with network/time diversity and packet-level forward error correction. Additionally, IPConnect can bridge local area network (LAN) segments across wide-area networks with seamless tunneling to enhance reliability of program and signal transport across large geographical regions with multiple receiving and transmitting sites.

With its three network interfaces, IPConnect’s data gateway provides extra protection through packet encapsulation, which encloses external IP data packets in a GatesAir protocol wrapper as it moves across IP networks. IPConnect provides this protection for studio-generated data, as well as IP data from external sources. While the former might include RDS data or SNMP control signals to trigger a command at the transmitter site, the latter may incorporate program or control data coming from a network operations center, satellite feed or advertising service.

As the next-generation member in GatesAir Intraplex family of IP codecs, the award-winning IPConnect leverages the strengths of previous IP Link codecs—including GatesAir’s patented Dynamic Stream Splicing (DSS) technology to mitigate IP packet loss, eliminate off-air time, and optimize stream reliability.

GatesAir’s Intraplex® LiveLook application for IP Link, NetXpress™, and HD Link™ provides advanced network analytics and monitoring capabilities at an affordable price. It is an invaluable tool for optimizing and monitoring network performance. Broadcasters are increasingly using IP networks for audio contribution and distribution. While IP networks provide clear benefits for both cost and flexibility, there are network impairments which must be overcome to realize the reliability required for broadcast application. While the Intraplex® IP Link platform provides several packet loss mitigation techniques, it is essential to understand the patterns of packet losses as well as other impairments on the network connection to optimize these techniques.

Intraplex LiveLook provides both a real-time analytics as well as a monitoring and notification platform for the IP Link audio codec systems. The analytics capability of LiveLook uses Burst Packet Loss modeling technique to analyze the patterns of packet losses, which is then used by the internal decision tree to provide recommendation on the most effective packet loss mitigation technique of the IP Link to apply.

The monitoring capability can simultaneously collect long-term statistics on multiple audio streams, which can be used for historical analysis. The notification capability creates a separate alarm log for each audio stream and can optionally send email notification to the user on the state of the audio stream.
