Scalable Video Coding (SVC)

The most recent and highly efficient video coding standard H.264/AVC has recently been extended by scalability tools, developed mainly by researchers at Fraunhofer HHI. This so-called Scalable Video Coding (SVC) extension allows for decoding the same video content at variable resolutions, frame rates or image fidelity, just by extracting parts of a scalable bit stream, without any need for transcoding. As will be demonstrated, application areas of SVC include simultaneous transmission of multiple HD formats (720p/1080p) as well as Mobile TV at QVGA and VGA resolution.

Mobile TV

Mobile TV offers opportunities for new audio-visual services. One most appealing application is Visual Radio, which is characterized by excellent audio, accompanied by visual information (music covers, slide shows, information charts etc.) at a low frame rate (e.g. 0.5 Hz). A Visual Radio service based on T-DMB is shown, using a HE-AAC audio codec and an H.264/AVC video codec running at very low rates (15-20 kbit/s). This demonstration shows the latest product out of a complete family of AV encoding and crypting solutions for DVB-H, T-DMB, DAB-IPDC and MBMS developed by Fraunhofer HHI.

Low Delay Streaming of 3D Graphics

Modern computer games pose high demands on CPU power and are usually only available on high end PCs and game consoles. In order to enable ubiquitous gaming in a home environment, hotel, or café, a 3D graphics streaming solution has been developed. From a server executing the games, the graphics commands are intercepted, encoded and streamed to low cost end devices, where they are rendered locally. The object-based approach offers high visual quality at low delay, crucial for gaming and interactive graphics applications.
