Abstract
A method mechanism for streaming multi-viewpoint virtual reality (VR) content via Dynamic Adaptive Streaming over Hypertext Transfer Protocol (HTTP) (DASH) is disclosed. The mechanism includes receiving media content including a VR video sequence. A DASH Media Presentation Description (MPD) is generated. The MPD includes an indication specifying that a portion of the media content that is related to a first viewpoint is associated with a timed metadata representation. A request is received from a client for the media content. The DASH MPD, including the indication, is transmitted to the client in response to receiving the request to support communication of the media content to the client.
