Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises: receiving, at a first device, a metadata file from a second device; and determining a descriptor in a data structure in the metadata file, a presence of the descriptor indicating that the data structure is for providing a picture-in-picture service, and the data structure indicating a selection of a first set of bitstreams of a first video and a second set of bitstreams of a second video for the picture-in-picture service.

Abstract: Systems and methods for managing a Network Based Media Processing (NBMP) workflow are provided. A method includes obtaining a first network based media processing (NBMP) workflow description document (WDD); creating a first workflow corresponding to the first WDD; managing at least one media processing entity (MPE) according to the first workflow; obtaining an update comprising a second WDD, wherein the second WDD includes a continuity flag indicating whether a second workflow corresponding to the second WDD is a continuation of the first workflow; creating the second workflow; and managing the at least one MPE according to the second workflow.

Abstract: Example techniques described herein involve a point-of-contact (POC) playback device that operates as an intermediary between the cloud and a media playback system that includes the POC playback device. As the intermediary, when the cloud issues a command to the media playback system, the POC playback device may perform some or all processing of the command to determine how to implement that command in the media playback system. For instance, the POC playback device may determine the target devices for a command, and then cause the target devices to carry out the command. This processing by the POC playback device may simplify control of the media playback system from the perspective of third party controllers, as these controllers need not have full and/or completely up-to-date knowledge of the media playback system functionality and status, among other possible benefits.

Abstract: A Unified Content Delivery Network system (UCDN) system which is formed from a network of one or more inter-operable Peer networks. A hierarchical hybrid adaptive Secure Peer-Assisted Networking System (termed SPAN-AI),using a hierarchical AI driven approach under a unified secure content-addressable architecture which is based on five key SPAN-AI sub systems: unified naming; unified discovery; hybrid adaptive routing; scalable pubsub; and embedded security; all of said five key SPAN-AI sub systems securely integrated and jointly optimized via a hierarchical, pluggable AI framework, with an associated simulation, training, and development pipeline that embeds AI agents with varying degrees of awareness and optimization capabilities at peer, edge, or core or other network levels (hierarchies).
