Abstract: In certain aspects of the disclosure, a method, a computer-readable medium, and a system for foveated rendering of omnidirectional media content are provided. The method includes receiving a request to access a stream of media data associated with the omnidirectional media content at a point in time the client is accessing the stream of media data for foveated rendering of the omnidirectional media content; determining an initial portion of media data, starting from the point in time the client requests to access, for foveated rendering of the omnidirectional media content for delivery to a client device; and transmitting, in response to the request, the initial portion of media data. The initial portion of media data comprises a portion of the omnidirectional media content for a viewport that is foveated rendered or to be displayed using foveated rendering on the client device according to the request.

Abstract: The techniques described herein relate to methods, apparatus, and computer readable media configured to encode and/or decode video data. Immersive media data includes a first patch track comprising first encoded immersive media data that corresponds to a first spatial portion of immersive media content, a second patch track comprising second encoded immersive media data that corresponds to a second spatial portion of the immersive media content that is different than the first spatial portion, an elementary data track comprising first immersive media elementary data, wherein the first patch track and/or the second patch track reference the elementary data track, and grouping data that specifies a spatial relationship between the first patch track and the second patch track. An encoding and/or decoding operation is performed based on the first patch track, the second patch track, the elementary data track and the grouping data to generate decoded immersive media data.

Abstract: The techniques described herein relate to methods, apparatus, and computer readable media configured to generate media data for an immersive media experience. A set of parameters for processing a scene description for an immersive media experience are accessed. Multimedia data for the immersive media experience is accessed, including a plurality of media tracks, each media track comprising an associated series of samples of media data for a different component of the immersive media experience, and a derived track comprising a set of derivation operations to perform to generate a series of samples of media data for the client for the immersive media experience. A derivation operation is performed to generate a portion of media data for a derived media track, including processing the plurality of media tracks to generate a first series of samples of the media data for the immersive media experience, and outputting the derived media track.

Abstract: A method performed by a control device includes: receiving forwarding information of many network devices in a network, where the many network devices in the network include a first edge device and a second edge device; determining, based on the forwarding information of the second edge device, information about a first network address that is reachable to the second edge device and that is outside the network; and estimating, based on the first network address information and the forwarding information of the plurality of network devices, whether one or more packets whose destination addresses are covered by the first network address information and that enter the network through the first edge device can be forwarded to the second edge device through the network.

Abstract: A network reachability verification method and apparatus, and a computer storage medium are provided, and pertain to the field of network technologies. The method includes: obtaining a source interface and a destination interface that correspond to a virtual packet in a target network; and verifying reachability of the virtual packet in an overlay network based on a logical topology of a plurality of forwarding instances of a plurality of network devices in the target network, routing information of the plurality of forwarding instances, a source forwarding instance corresponding to the source interface, and a destination forwarding instance corresponding to the destination interface. In this way, single-layer reachability verification on the overlay network in the target network is implemented, and verification accuracy is high.
