Abstract: In one example, a processing system including at least one processor may obtain viewport information of a mobile computing device associated with a panoramic video, map the viewport information to a plurality of blocks of a frame of the panoramic video in accordance with a cube map projection of the frame, encode the plurality of blocks into a projected frame, and transmit the projected frame to the mobile computing device. In another example, a processing system of a mobile computing device including at least one processor may obtain viewport information of the device associated with a panoramic video, transmit to a server the viewport information, obtain from the server a projected frame of the panoramic video comprising a plurality of blocks of a frame of the panoramic video that are associated with the viewport information in accordance with a cube map projection of the frame, and buffer the projected frame.

Abstract: Aspects of the subject disclosure may include, for example, receiving, over a communication network, a plurality of requests for frames of video content to provide to a mobile device. Further embodiments can include determining a first portion of the plurality of requests are for pre-fetch frames of the video content, and providing, over the communication network, the pre-fetch frames to the mobile device over a default bearer path. Additional embodiments can include determining a second portion of the plurality of requests are for emergent frames of the video content, and providing, over the communication network, the emergent frames to the mobile device over a dedicated bearer path. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, a virtual processing system initiating a first streaming session with a content streaming server to receive content data, creating a first transport connection with a viewer streaming the content data in a second streaming session with the content streaming server by imitating a transport connection of the content streaming server with the viewer, creating a second transport connection with the content streaming server by imitating a transport connection of the viewer with the content streaming server, splitting the first streaming session between the content streaming server and the viewer, and streaming the content data to the viewer. Other embodiments are disclosed.

Abstract: A multimedia conferencing service uses accessible-forwarding-plane network elements such as OpenFlow® controllers and OpenFlow®-enabled switches. A conferencing server receives a conference subscription request including a network address of a L2/L3 signaling server, and connects to an accessible-forwarding-plane controller to control an accessible-forwarding-plane switch. Flow tables and group tables are managed to classify traffic with minimum table usage and update frequency. Media channels are established between clients through the OpenFlow®-enabled switches, relieving bottlenecks at the conferencing server.
