Aspera Streaming software

Today’s live video opportunities demand new transport solutions that use Internet (IP) networks in place of legacy satellite delivery. As a result, various kinds of technologies and services have been introduced over the past several years that have attempted to deliver video reliably over the Internet such as services that use forward error correction (FEC) over UDP and peer-to-peer distribution. However, these technologies have not been able to provide the consistently exceptional broadcast quality and “zero-delay” experience provided by traditional satellite backhaul and transmission: Neither FEC over UDP nor peer-to-peer networks can guarantee live transmission rates over commodity Internet with variable round trip time and packet loss, and unlimited data rates. Aspera's video streaming software built on top of the FASPStream protocol is the world's first terrestrial solution to provide as good or better transport results as satellite delivery, but at a much lower cost. 

The Streaming for Video software solution was created from the ground up by Aspera with the potential to revolutionize the way that live and near-live video is transported. Broadcast video transport over long distances (ingest and backhaul, pitch and distribution) has traditionally relied on linear satellite systems. However, satellite transport has significant limitations for today’s Internet video demands, where video is produced anywhere and everywhere, and consumer appetite for live and interactive second-screen video is explosive. 



  • Inline transcoding: Begin encoding process while the transfer is still in progress
  • Accelerate media delivery or play out
  • Perform inline file validation while data is being transfer rather than upon transfer completion


  • Speed capture and distribution from remote locations to improve data acquisition
  • Initiate time-sensitive image processing analysis of large data files sooner to make faster business decisions


  • Transfer high-resolution medical images, with speed, security and privacy
  • Enable diagnostic-quality viewing by healthcare practitioners in remote locations to eliminate wait times and accelerate diagnosis



Saves considerable costs by reducing or fully replacing satellite delivery services with much more affordable terrestrial IP networks.


Guarantees timely arrival of live video and data with glitch-free play out and negligible start up delay/pre-buffering, independent of network round-trip delay and packet loss .

SEAMLESS WORKFLOW integration with CLOUD and HYBRID environments

Enables video on demand and production workflows for transcoding and distribution by seamlessly integrating with modern cloud computing environments, unlike satellite delivery systems that require huge investments of capital or long startup times that are impractical for one-time events and modern on-location original programming and news.


Fully utilizes the available bandwidth of commodity IP networks to send and receive broadcast quality video streams at maximum speed, regardless of distance or network conditions.


Achieves high-speed, robust and reliable streaming with end-to-end progress reporting and performance monitoring. All FASPStreams are encrypted in transit and security authenticated using standard public/private key authentication or Aspera's multi-tenant access key system.

The Streaming for Video software is built on the FASPStream transport, a new breakthrough alternative for Internet video transport. At the core of this software is Aspera's patented FASP transport technology that now provides fully reliable in-order byte stream delivery for live feeds over commodity IP networks using the new FASPStream architecture.


  • Glitch-free play out with negligible start up delay at “any” Internet distance
  • Less than 2 seconds of delay from live for 50 Mbps video sources over global Internet networks with round-trip delays of 200 milliseconds and 2% packet loss and for 10 Mbps sources over networks with 500 milliseconds round trip delay and 5% packet loss

Stream Provider and Receiver interoperability

  • Transport any live video source available on local multicast, unicast UDP, unicast TCP, or growing file source and will output video to the same options.
  • Provides a uniform lossless, in-order byte stream transport that equally supports constant bit rate and adaptive bit rate formats with performance independent of video encoding details


  • One stream source can be sent to multiple destinations concurrently and provides built-in path redundancy
  • Server hosts are natively clustered; stream sessions failover automatically to another host
  • Aspera management services automatically reconnect and restart failed streams on network outage 

Robust SECURITY and authentication 

  • All FASPStreams are encrypted in transit and security authenticated using standard public/private key authentication or Aspera’s multi-tenant access key system
  • Built in access control policies can be used to restrict stream providers and consumers by stream protocol, IP address, and ports

Aspera Interoperability and Management

  • FASPStream sessions are designed for full interoperability with the Aspera file transfer stack including writing to cloud based “object” storage.
  • RESTful APIs allow production workflow and broadcast management systems to manage streams and provide status
  • Stream sources can include cloud and on premises transcoders / encoders that read from stream and file, or provide stream outputs or growing files.


  • Linux 64-bit: Ubuntu 12-14, RedHat 6-7, CentOS 6-7, Fedora 16-20, Debian 6-7, SLES 11-12 Kernel 2.4 or higher and libc version GLIB 2.3.4+


  • All host computers or appliances need a Streaming for Video license, please contact Aspera Sales for more information.

What's New in StreamING

The new streaming platform can support any streaming provider (live video or data from TCP as well as UDP sources) without modification, and across all platforms (browser, mobile and desktop).

  • Ascp4 Streaming Client - Aspera's new file and stream transfer binary, available for Mac, Windows, and Linux, sends local FASPstream source feeds (video or data) via a FASP session to a peer ascp4 process, which outputs the received stream to a local target
    • A New TCP provider allows ascp4 to 'tunnel' any local streaming source - TCP, UDP unicast or UDP multicast - over FASP to any target destination, including Stream-to-Stream, Stream-to-File and File-to-Stream (with support for object storage)
    • Supports input/output over source-specific multicast as well as standard multicast, and variable sized UDP datagrams
    • For live data streams, such as live log data, a new segmenter provider writes segments of the stream periodically to a file including direct to HDFS/S3 and a new Kafka provider writes directly to Kafka
    • New FASPstream APIs in C/C++, Java and .NET expose the ascp4 session to applications. Many enhancements in robustness, error handling, and programming model over early versions
  • New Streaming Options in the Aspera Files SaaS allowing users to configure Aspera nodes with streaming capability explicitly or through auto-discovery and create new live ingest streams, start/stop active streams, and publish live feeds post transcoding for playout via Connect
  • New Architecture and Software Stack - This new architecture provides a TCP-like replacement for streaming applications already using TCP such as HTTP and RTMP for web video or data streaming. The architecture exposes a socket-style API with full bidirectional communication between client and server over the FASP session, so that applications (mobile iOS, tvOS, Android, web browsers, streaming services) do not need to change to take advantage of FASP. Key components include:
    • Aspera's Next-Generation FASP Protocol Version 4, which provides a fully bi-directional reliable bytestream transport session to the application (no separate control connection or out-of-channel synchronization required)
    • New Gateway, a lightweight TCP-to-FASPstream proxy software that provides a 1-1 bidirectional bridge between a local TCP and a local FASP session. When run on or near a standard TCP-based server (HTTP, RTMP, etc) it enables clients to maintain their interaction with the remote TCP server while using the FASPstream session over the WAN
    • New Connect, a lightweight agent enabling FASPstream delivery to the browser via a simple javascript library or to any TCP-based application on the local system. Allows any bulk data upload/download or video streaming request to be carried over FASPstream, and available on all browsers and applications
    • New SDKs allow mobile, browser, and desktop applications to embed FASPstream capability as a direct replacement for TCP:
      • - a client-server SDK with FASPstream sessions exposed via a regular POSIX (TCP-like) socket
      • - a C++11 client-server SDK, extends the well-known ASIO framework via FASPstream sessions exposed as a standard ASIO socket with both synchronous and asynchronous methods
      • - A client-side javascript SDK works in tandem with the Connect to provide a FASPstream "socket" inside a webapp, with a WebSocket (RTCDataChannel)-like API, and a higher-level AsperaXHR class that provides HTTP over FASPstream and can be used as a replacement to the native XMLHttpRequest object provided by the browser
      • - a client-side Swift SDK with a "low-level" socket-like API that takes advantage of the well-known GrandCentral/dispatchIO framework for asynchronous processing, and a higher level integration with Apple's "URL Loading System" to provide a URLSessionStreamTask for raw streaming
