Workshop: Streamed Media in Immersive Scene Descriptions

Zoom Webinar, September 29 and 30, 2021


MPEG and The Khronos Group are hosting a joint workshop on Streamed Media in Immersive Scene Descriptions. The primary purpose of the workshop is the exchange of information on developments in MPEG that relate to Khronos specifications, primarily glTF 2.0, and to seek feedback on the approaches taken. In addition, the workshop aims to identify additional synergies and opportunities for cooperation regarding Khronos standard APIs for GPU processing and XR run time APIs, MPEG’s work on digital representation of digital media, and 3GPP’s 5G-based advanced delivery of media.

The webinar will be run under the umbrella of the MPEG-I Scene description Ad Hoc Group (AHG) and is open to the public under the MPEG AHG policies as available here. Registered users are expected to consent to the policies laid out, in particular §9.

The workshop will be run over two days with a three hour Zoom session each day. The detailed program is provided below.
