5G Predictive HARQ

HARQ is a physical layer mechanism provides retransmissions based on the feedback to increase robustness. Predicitve HARQ focuses on providing the HARQ feedback earlier by predicting the decoding outcome, designated as Early HARQ (E-HARQ).

5GXR

We explore ways to efficiently stream volumetric videos over 5G networks. Our work focuses on development of a volumetric video streaming system that offloads the rendering to a powerful cloud/edge server and only sends the rendered 2D view to the client instead of the full volumetric content.

Versatile Video Coding (VVC): High-level Syntax and System Integration

Considerable progress has been made in the field of video coding [e.g., versatile video coding (VVC)] for the purpose of improving compression efficiency (e.g., reducing the amount of data needed to store or transmit a video). Just as relevant, however, is the progress that has been made in enabling video applications through design of the codec high-level syntax and the system integration.

Volumetric Video Formats

Volumetric video represents a new way of experiencing immersive media content. Compared to traditional two-dimensional video, volumetric video requires the storage of geometric information in addition to texture, which results in a huge amount of data. Therefore, a suitable compression and storage format is essential for such applications.

360° Video - MPEG-OMAF

The MPEG-OMAF standard (officially ISO/IEC 23090-2) is the first international standard for storage and distribution of 360° Video, with significant contributions from Fraunhofer HHI’s Video Coding and Analytics department. OMAF specifies tile-based streaming of 360° Video which allows for significantly higher resolution at the end device.
