isovideo to Showcase Industry-First Stream-Based 4K/UHD/HD Standards Conversion/Transcoding/Transport Viarte Server Cluster at the NAB 04

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 isovideos 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:

archiving lossless compressed or high-quality compressed such as prores-hq,

proxies for editing or quick review,

preparing and sending files to streaming servers,

pushing converted files to NAS or SAN storage for IP workflows.

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

Superior Conversion Quality: Viartes motion compensated (MC) deinterlacer is the only technology that offers GPU-accelerated realtime HD throughput with 100% vertical resolution, no visible flicker, and a substantial 17% average reduction in HEVC/H.264 bitrates. Viartes MC frame-rate conversion offers smooth and clean video for any frame-rate in common use. Its adjustable, accurately simulated motion blur reduces playback motion judder when converting from higher to lower frame-rates. Added motion blur has the further benefit of significant savings in compressed bandwidth with subsequent H.264/HEVC compression

Low Delay: latency is less than 15s, from ingest to first output stream.

High Throughput: for example, realtime (or even faster than realtime) archive quality encoding, UHD/4k/8k frame rate conversions can be achieved with a large cluster. Note that performance is dependent on total processing tasks with given resources.

Highly flexible configuration: multi-concurrent conversion between any combination of frame-rate/resolutions/aspect-ratio/scan-type. Multiple codecs with a number of profile controls. Accurate output timecode control. Automatic handling of mixed cadence, and overriding erroneous metadata.

Highly efficient pipelined execution from ingest to final delivery.

Easy workflow integration via NFS, SMB or Open-iSCSI mounts.

Efficient scalability up to Class-C network capacity supports automatic and redundant server discovery, and synchronous individual server maintenance shut-down.

Savings

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.

Award

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.
