Abstract: An exemplary method for intelligent compression uses a foveated-compression approach. First, the location of a fixation point within an image frame is determined. Next, the image frame is sectored into two or more sectors such that one of the two or more sectors is designated as a fixation sector and the remaining sectors are designated as foveation sectors. A sector may be defined by one or more tiles within the image frame. The fixation sector includes the particular tile that contains the fixation point and is compressed according to a lossless compression algorithm. The foveation sectors are compressed according to lossy compression algorithms. As the locations of foveation sectors increase in angular distance from the location of the fixation sector, a compression factor may be increased.

Abstract: Methods and devices for managing data flows for concurrent multimedia applications executing on a device including a SoC, in response to determining that a temperature or power consumption exceeds a threshold are disclosed. A lowest priority data flow may be identified. A data flow path associated with the identified lowest priority data flow may be traced. A multimedia parameter of any hardware module along the data flow path may be reduced. When the temperature or power consumption no longer exceeds the threshold, a highest priority data flow among the multimedia applications that has had the multimedia parameter reduced may be identified. A data flow path for a data flow associated with the identified highest priority data flow may be traced. The multimedia parameter may be restored to an original value along the traced data flow path for the data flow associated with the identified highest priority data flow.
