Abstract
Systems, methods, and instrumentalities are disclosed for client centric service quality control. A first viewport of a 360 degree video may be determined. The 360 degree video may comprise one or more of an equirectangular, a cube-map, a cylindrical, a pyramidal, and/or a spherical projection mapping. The first viewport may be associated with a spatial region of the 360 degree video. An adjacent area that extends around the spatial region may be determined. A second viewport of the 360 degree video may be determined. A bitstream associated with the 360 degree video may be received. One or more enhanced regions may be included in the bitstream. The one or more enhanced regions may correspond to the first and/or second viewport, A high coding bitrate may be associated with the first viewport and/or the second viewport.
