Media content segments may be identified in the defined representation in which the determined quality metric is below a selected threshold. The identified media content segments may be replaced with corresponding media content segments from a different representation that are described in the MPD file to form a modified MPD file, wherein the quality metric for the corresponding media content segments is greater than the selected threshold in order to provide a substantially constant quality playback of the media content segments in the defined representation. | 03-24-2016 |
20160100099 | INTERACTIVE VIDEO CONFERENCING - Technology for a local user equipment (UE) operable to perform video conferencing with a remote UE is disclosed. The local UE can define a region of interest (ROI) within a field of view of a camera of the remote UE. The local UE can map the ROI to one or more pan, tilt, zoom and focus (PTZF) commands. The local UE can send the one or more PTZF commands to the remote UE, wherein the remote UE is configured to identify the ROI based on the one or more PTZF commands. The local UE can receive encoded video within the ROI from the remote UE. The encoded video can include the regions within the ROI at an increased zoom level while substantially maintaining a defined quality level to enable the encoded video within the ROI to be rendered and displayed at the local UE. | 04-07-2016 |
20160105478 | CARRIAGE OF MEDIA CONTENT QUALITY INFORMATION - Technology for communicating Moving Picture Experts Group (MPEG)-2 streaming video quality information is disclosed. A network element can generate quality access units that are associated with one or more media access units in a media content stream representation. The quality access units can indicate quality metadata for the media access units in the media content stream representation. The network element can encapsulate the quality access units in an MPEG-2 transport stream (TS). The network element can generate a quality extension descriptor that describes the quality metadata indicated in the quality access units. The network element can communicate, to a user equipment (UE), the quality extension descriptor according to a defined periodicity. The network element can communicate, to the UE, the quality access units in the MPEG TS with the media access units, wherein the quality access units are interpreted at the UE based on the quality extension descriptor. | 04-14-2016 |
