弗劳恩霍夫提出MPEG-DASH流与HEVC和7.1 HE-AAC在IBC
Fraunhofer’s IBC presentations that include multi-screen, 动态AD插入和加密技术, 支持MPEG-DASH标准.
荷兰阿姆斯特丹(9月12日)
A major shift in audio and video streaming techniques has emerged with the introduction of an ISO standard for Dynamic Adaptive Streaming over HTTP (DASH), 也称为MPEG-DASH. Fraunhofer is a codeveloper of the MPEG-DASH standard and a leading source of DASH implementations. 对于IBC, 三个弗劳恩霍夫研究所- IIS, HHI and FOKUS – collaborated and demonstrate their solutions for DASH-based streaming systems.
DASH delivers high quality streaming multimedia content over the Internet through conventional HTTP servers. 它可以无缝地适应不断变化的网络条件, which eliminates buffering experiences that frustrate viewers.
At IBC, Fraunhofer IIS and Fraunhofer HHI demonstrate the world's first DASH streaming system with 7.1 HE-AAC Multichannel Audio and the new HEVC Video coding standard. The combination of the two state-of-the-art MPEG codecs within a DASH adaptive streaming system allows for the most efficient delivery of high quality content at the lowest possible data rates solely based on international ISO standards.
Fraunhofer IIS是HE-AAC v2的主要开发者, the mandatory stereo and optional multichannel codec in the DASH-AVC/264 implementation guidelines developed by DASH-IF. HE-AAC is the ideal choice for DASH due to its encoding efficiency that allows for flawless audio bit rate switching and surround sound streaming, without the need to switch to stereo when bandwidth is constrained.
Fraunhofer HHI, the main developer of HEVC, focuses on combining DASH with HEVC. Fraunhofer HHI's new software toolset for DASH fully supports HEVC content encoding. Its authoring tool supports the VoD profile of the ISO Base Media File Format (BMFF) as well as encapsulating HEVC streams into ISO BMFF segments. Fraunhofer HHI’s DASH client SDK naturally supports HEVC over DASH based on ISO BMFF. HEVC requires only half the bandwidth for high quality video transmission needed by its predecessor AVC.
Fraunhofer FOKUS introduces at IBC its FAMIUM ecosystem for the consumption and delivery of adaptive bit rate content as well as Digital Rights Management (DRM) protected content. FAMIUM enables platform-independent multiscreen and rich media applications, bundling several DASH and DRM related functionalities for use in web applications. It is based on the W3C working draft Media Source Extensions (MSE) and Encrypted Media Extensions (EME). FAMIUM takes the opportunities of this technology and enhances it with multiscreen, 同步和DRM功能. Use cases such as live TV in the browser without the need for plugins, including dynamic advert insertion or synchronous playback of video with complementary content on multiple screens become possible with the FAMIUM ecosystem solution.
