Fraunhofer and Unified Streaming Platform are adding multichannel HE-AAC to MPEG-DASH streaming

Fraunhofer and Unified Streaming Platform are adding multichannel HE-AAC to MPEG-DASH streaming | Video Breakthroughs | Scoop.it

Fraunhofer IIS and Unified Streaming (USP) have begun a collaboratin designed to extend the ecosystem for HE-AAC MPEG-DASH streaming, enabling broadcasters and service providers to deliver the best possible MPEG-DASH (dynamic adaptive streaming over HTTP) streaming experience for video and audio-only services. 

 

The two parties say that HE-AAC has emerged as the global standard for broadcasting and streaming multimedia content, including Internet radio or Web TV, digital radio and digital television. It is natively supported by Android Jelly Bean, iOS, Windows 7/8, Mac OS, the leading HTML5 browsers. Therefore, says Fraunhofer and USP, service providers in many cases only need to encode their content in a single audio format, HE-AAC Multichannel.

Nicolas Weil's insight:

Interesting partnership - one more for the pushy USP !

Audio Catches Up: Online Video Rocks with Multichannel Audio

Audio Catches Up: Online Video Rocks with Multichannel Audio | Video Breakthroughs | Scoop.it

As movies move online and go mobile, sound gets some respect with updated codecs, more TLC, and a better attitude.

 

The next time you walk past the hollowed-out hulk of a Blockbuster store in your neighborhood, you’ll be reminded that there is a war going on. Actually, the format wars have been going on for decades now, but the debris left behind by the physical media era underscores how the battles have migrated to the virtual realm now. One of the defining characteristics of this epoch of the conflict, though, is that it’s becoming less about the origin of the content, or even the format it takes in its travels, and more about the places that it ends up. Streaming to an ever-widening selection of devices and platforms puts content under a variety of pressures, and while the HD video dogfights get all the glory, audio— media’s perennial underdog—has some pretty capable allies of its own.

Announcing Adobe Media Server 5.0.1 : Closed Captioning, DRM for HLS, Multiple Language Audio Tracks, SIP Gateway

Announcing Adobe Media Server 5.0.1 :  Closed Captioning, DRM for HLS, Multiple Language Audio Tracks, SIP Gateway | Video Breakthroughs | Scoop.it

Adobe Media Server 5.0.1 brings to you – Closed Captioning compliance, DRM protection for millions of iOS Devices and Playback Support for Multiple Language Audio Tracks.

 

Adobe Media Server 5.0.1 comes bundled with Adobe Media Gateway – a powerful technology to connect SIP telephony devices to flash based applications.

 

Closed Captioning :

Adobe Media Server supports CEA-608 (also called Line 21) and CEA -708 closed captions in video files containing H264 video codecs. This plays in HLS, HDS and RTMP Streaming protocols. Additionally, the timed text track defined by Apple for Quicktime movie files is also supported. Adobe Media Server 5.0.1 also provides support to embed your content programmatically while encoding the content via an AMF message. This works for RTMP and HDS techniques.

 

Support for Multi Language tracks :

Adobe Media Server 5.0.1 has support for including multiple language tracks for HTTP video streams, without requiring duplication and repackaging of the video for each audio track. This feature, called as “late” binding of audio tracks allow content providers to easily provide multiple language tracks for a given video asset, at any time before or after the asset’s initial packaging. The OSMF framework based Strobe Media player provides support for allowing the viewers to switch between audio tracks either before or during playback.

 

Content Protection for HLS Streams :

Adobe Media Server offers both stream and content protection across HLS, HDS and RTMP protocols. It also enables DRM protection using the Adobe Access DRM license server. Now, Adobe Media Server can dynamically segment, encrypt, and deliver standard MP4 assets using the HLS format with Adobe Access DRM policies on native Apple iOS applications (using the Adobe Access Objective-C library for iOS).
