Abstract:
Technology for distributing presence information by a presence server in an Internet protocol (IP) multimedia subsystem (IMS) based dynamic adaptive streaming over hypertext transfer protocol (HTTP) (DASH) service is disclosed. In an example, a user equipment (UE) can be operable to act as a presentity and include computer circuitry configured to: Generate a trigger event during a DASH session; and publish presence information including content being consumed to a presence server. The published content can include DASH content.
Abstract:
Technology for a first multimedia telephony services over internet protocol (IP) multimedia subsystems (IMS) (MTSI) client operable to support region of interest (ROI) signaling with a second MTSI client is disclosed. The first MTSI client can identify a requested region of interest (ROI). The first MTSI client can encode the requested ROI for transmission to the second MTSI client via a real-time transport control protocol (RTCP) feedback message. The first MTSI client can decode encoded video received from the second MTSI client that corresponds to the requested ROI.
Abstract:
Technology for a local user equipment (UE) operable to perform video conferencing with a remote UE is disclosed. The local UE can receive a set of predefined region of interests (ROIs) from the remote UE. The local UE can select a predefined ROI from the set of predefined ROIs received from the remote UE. The local UE can communicate the predefined ROI to the remote UE that directs the remote UE to capture video within the predefined ROI and encode the video within the predefined ROI. The local UE can receive encoded video within the predefined ROI from the remote UE. The encoded video can include regions within the predefined ROI and excluding regions outside the predefined ROI. The local UE can provide the encoded video within the predefined ROI for rendering and display at the local UE.

Abstract:
In a video conferencing application, a user viewing a scene can performing zooming by selecting an area in the scene, then dynamically switching a video feed of the scene to the selected area of the scene. The hardware and software of the video conferencing application can limit the video transmitted to the user to include only the selected area of the scene. Transmitting only the selected area of the scene, and excluding the non-selected area of the scene from transmission, can more efficiently use the available bandwidth of the video conferencing application.

Abstract:
Technology for operating a video conferencing application at a local user equipment (UE) that supports an interactive zooming feature is disclosed. A local UE can define a region of interest (ROI) within a field of view at a remote UE. The local UE can communicate the ROI to the remote UE via a real-time transport control protocol (RTCP) feedback message, wherein the RTCP feedback message directs the remote UE to capture video within the ROI and encode the video within the ROI. The local UE can receive the encoded video within the ROI from the remote UE, the encoded video including regions within the ROI and excluding regions outside the ROI. The local UE can receive actual transmitted ROI corresponding to the encoded video from the remote UE via an RTP header extension. The encoded video within the ROI can be rendered for display at the local UE.
