Unified Streaming

Unified Streaming Tools

Unified Streaming provides software for streaming, offline and on the fly packaging and recording of streaming video and audio. Unified Streaming platform aims to deliver content from a single source to various formats, avoiding the need for duplicate content storage. It fits into existing web servers (Apache, IIS, Nginx and Lighttpd) and runs on Windows, Linux and Unix.^[1][2]

The platform started as dual licensed h264 webserver module,^[3] which in turn has roots in Open Source Lighttpd Flash module mod_flv_streaming.^[4] Unified Streaming was launched in 2012 as a subsidiary of Code-Shop (founded in 2005) after several years of research in streaming media. The company provides several streaming software

• Unified Packager: software to package content in streaming friendly formats such as MP4. fMP4, Common Media Application Format and generate streaming manifests
• Unified Origin: A webserver that provides on the fly packaging, sub-title conversion, on-the-fly encryption and manifest generation that also scales to large numbers of users.
• Unified Capture: A tool for capturing live media content or online streaming content for storage in archives or for future streaming
• Unified Remix: A tool for on the fly editing of videos, enabling content stitching and insertion of contents in streaming presentations.
• Unified Edge: A deployment mode combining origin/remix for deploying Unified Origin on the edge for advanced streaming architectures with edge based media processing

Research and Standardization

Unified Streaming is active research and standards: Unified streaming is a partner of the 5G PPP Superfluidity project to create heterogeneous 5G networks, sponsored by European Commission's Horizon 2020 research and innovation programme.^[5][6] In this project, amongst others it has shown how media streaming could benefit from large scale deployment on OpenStack and in edge computing scenarios that will be present in the next generation of (mobile) Networks.

Unified Streaming is a member of Moving Picture Experts Group (MPEG) ^[7] Consortium where it chaired the network based media processing group together with Samsung, exploring how on-the-fly media processing will benefit advanced media services in future networks. The main aim of NBMP is to define new interchange formats between central and edge sites or within a cloud environment, facilitating the processing functions such as transcoding, content stitching etc. This standard serves as the delivery standard for MPEG-I which defines standards for advanced immersive services such as based on 3 and 6 degrees of Freedom. In addition it was chair and contributor to MPEG AhG on Point Cloud Compression that is developing a standard for six degrees of freedom video, Unified Streaming was one of the nine companies (including all major mobile device manufacturers) to contribute to the call for proposals on point cloud compression in October 2017.
