isovideo to Showcase Industry-First Stream-Based 4K/UHD/HD Standards Conversion/Transcoding/Transport Viarte Server Cluster at the NAB 2014

(Beaverton, Oregon - March 16, 2014) isovideo will be demonstrating the latest version of their highly scalable and efficient Viarte servers with stream-based, on-the-fly standards conversion/transcoding/transport capability. Also being demonstrated is a prototype of our upcoming product Vilan - an UHD capture/transmission server, for sending mathematically lossless HD/UHD/4k video in real time via 10 Gbits IP at NAB booth SU10211.

Fast Turn-Around Ip-Studio Workflow

Viarte standards conversion/transcoding gets a near-linear boost in throughput versus the number of Viarte servers, using isovideo's latest innovative, extremely efficient and scalable video splitting technology. This technology allows a network of Viarte server cluster to work together to dramatically increase throughput, while also allowing on-the-fly live IP file streams or file ingest, standards conversion, transcoding to multiple formats, and transport. Realtime on-the-fly processing dramatically reduces studio production turn-around, pushing out high quality file streams (possibly dozens for large clusters) in multiple formats, thereby allowing fast start of downstream workflow tasks such as:

New Applications: Live feed and Archives Productions

Viarte stream-based processing opens up a whole new set of applications beyond file-based operation. With the Vilan capture server sending true lossless-compressed HD/UHD over IP to one or more Viarte servers, a continuous video stream can be received and processed by networked, GPU accelerated Viarte cluster in realtime and with low delay. Cost-effective Vilan systems can be used at capture/contribution to send either compressed lossless video (equivalent to uncompressed) or a camera-compressed IP stream.

Viarte low-delay splitting technology also enables years of valuable accumulated high quality archives to be made instantly accessible with various formats on demand (including different frame rate/resolution/ codecs, etc) with best possible quality. For, example, pristine 1080i50/60 or 480i60 material can be transformed on-the-fly to 1080p50/60, 3820x2160p50/60, and 720p50/60 and pushed to stream servers for immediate viewing.

Key Advantages


Viarte server installations at central facilities enable on-the-fly local transcoding via remote live feeds, avoiding sending multiple derived formats from capture, and thereby saving significant bandwidth. In addition, the cost associated with renting and operating standards conversion/transcoding systems at the remote event location can be reduced significantly.


Viarte was one of five winners of the prestigious Game-Changer Awards by the IABM/NAB 2013, and was recognized as having the greatest potential to revolutionize the industry by a panel of impartial experts.
