A system for video streaming may include a video receiver configured to receive a video sequence. The system may further include a video priority analyzer configured to calculate coefficients that correlate cognitive or perceptual priority with spatial, temporal, or audio elements of the video sequence. The video priority analyzer may further determine a priority map using the calculated coefficients. The priority map may include a set of coefficients that is associated with a video interval of the video sequence. A video decision router may be configured to select a transcoding technique or bitrate level for each video packet based on the determined priority map. Further, the video decision router may transmit the packet according to the selected transcoding technique or bitrate level. |
