Vantage Shows ABR and Closed Captioning Leaps at NAB

Telestream is unleashing a number of additions to its Vantage transcoding and workflow automation software at NAB.

For multiscreen OTT workflows, Telestream will show Vantage Transcode with a new method of constructing adaptive-bitrate (ABR) packages that “significantly reduce delivery bandwidth needs and costs within multiscreen distribution applications”.

“This capability can achieve real-world bandwidth reductions of 25-40% whilst maintaining a premium viewing experience,” says Paul Turner VP of Enterprise Product Management.

"In the world of multiscreen media delivery, Content Delivery Network (CDN) costs are a significant issue for broadcasters. While traditionally they are used to fixed distribution costs, irrespective of viewing audience, this is not the case when distributing via CDN. These distribution partners charge on a “per-bit, per-viewer” basis, so the more multiscreen viewers, the higher the cost of distribution. Therefore, the ability of a product to produce high quality images at lower bit rates is a major consideration." 

For NAB, Telestream is also bringing integrated closed captioning technology into the Vantage workflow. On display will be a new subtitle and captioning service that integrates seamlessly into Vantage, providing a unique interface to read, write, and adjust subtitle and caption data. With the ability to automatically retime captions when performing frame-rate conversions or edits via Post Producer, this new service allows existing Vantage users to meet captioning requirements without disrupting their existing workflows and, conversely, gives those seeking a captioning and subtitling solution all the benefits of an industry-standard media processing platform. An integral part of the Vantage Media Processing Platform, this new capability can also provide captioning and subtitling services in the cloud with Vantage Cloud Subscriptions.

Also showcased at NAB will be the latest version of Wirecast, Telestream's live streaming software. This is said to be the industry's only cross-platform, all-in-one live streaming production software that enables capture, live production and encoding of live streams for broadcast to multiple servers and platforms simultaneously.

“With new powerful production capabilities, streamlined workflows, and expanded content source options, Wirecast offers the capabilities of more expensive hardware solutions with the flexibility and affordability of a software application,” said Turner. “With an ever expanding list of streaming destination partners such as Verizon Digital Media Services, YouTube, Microsoft Azure, Ustream and may others, Wirecast makes it easy to broadcast professional-looking live web shows, news, online gaming, sporting events, concerts, church services, corporate meetings, lectures and much more with just a few mouse clicks.”

Wirecast Go, a mobile live streaming application that converts any iPhone into a live broadcast studio, will also be demonstrated at NAB.

Gamers attending NAB will also be interested to see Gameshow, the firm’s new gamecasting software. It is a software application designed to help gamecasters create professional quality streams with graphic templates, dynamic editing, live switching, and green screen technology. “With a few clicks, users can pick and customize game templates, insert graphics, add widgets and start streaming to Twitch or YouTube,” Turner added.
