Yospace adds closed captions to Flash streaming

Posted on

SDK which allows Flash to interpret HLS streams now meets CEA-608 standard.

NAB 2013, Las Vegas, Booth SU8503: With closed captioning now an FCC requirement in the USA, and a powerful access tool elsewhere in the world, Yospace has announced full support for captions in its live streaming technology, including its unique solution which allows Flash players to display HLS content.

Yospace offers an SDK which allows a Flash player to consume HLS streams, and it is this which is now compatible with CEA-608 captioning. The CEA-608 standard defines the means by which closed captions are embedded within video data as it distributed, either by the means of traditional broadcast or internet streaming.

The result is that broadcasters and content owners can now meet the requirement to caption content online using HLS while using the workflows that exist to embed closed captions in broadcast.

“The support for CEA-608 in Apple devices means that broadcasters can already deliver closed captioning to a wide audience using a workflow they should find familiar,” explained David Springall, CTO and founder of Yospace. “By adding the same support in our Flash SDK for HLS, we have extended that reach to Flash-based players with no further workflow adaptations needed.”

The Flash player SDK, closed captioning, seamless content replacement and other leading edge streaming technologies will be demonstrated on the Yospace stand at NAB 2013, Booth SU8503.

Yospace brings seamless content replacement to Microsoft Smooth Streaming

Frame-accurate splicing for transparent advertising replacement and content blocking.

NAB 2013, Las Vegas, Booth SU8503: With broadcasters and content providers around the world looking to minimise operational expenditure and maximise revenues, Yospace is introducing a vital step forward: seamless in-stream content replacement for the Microsoft Smooth Streaming platform alongside content prepared for Apple HLS.

Content replacement allows a broadcaster to replace live material for which it does not have online rights, and to tailor advertising to the platform and the demographics of the user. Traditional technology downloads the replacement content in advance and expects the receiving device to perform the switching, which results in ugly transitions with buffering and spinning wheels. Consumers see this quality of experience as significantly lower than broadcast, so reject it.

The Yospace solution, which is established for HLS streams (used for Android, Blackberry, Samsung connected televisions and even the Microsoft Xbox as well as iPad and iPhone), replaces the content in the delivery stream thanks to close integration with the broadcast playout automation system. To the receiving device it is a single, seamless stream with no compromise in the quality of experience. The Yospace solution is now also available for Microsoft Smooth Streaming, which is typically used on Silverlight platforms in conjunction with PlayReady DRM.

“The internal architecture of the Smooth Streaming protocol lacks some of the flexibility of HLS, making content replacement technically challenging,” said David Springall, CTO and founder of Yospace. “Yospace has solved this problem, and can now give broadcasters exactly the same facilities for Smooth Streaming that exist for HLS.

“Our HLS SDKs for Windows 8 and Flash obviate the need to use Smooth Streaming in many cases,” he added. “However, where broadcasters have established Smooth Streaming workflows to enable PlayReady DRM, we have the technology to provide the advanced simulcast features they need to enhance their monetisation opportunities.”

Yospace will be demonstrating seamless content replacement across all platforms at NAB 2013, on Booth SU8503.
