摘要： A video decoder performs a method of dynamic voltage/frequency scaling (DVFS) for video processing. The method includes parsing a bitstream associated with a video to determine embedded information associated with a complexity of a first portion of the video, estimating the complexity of the first portion of the video using the embedded information, determining a voltage and frequency to be used for decoding the first portion of the video based on the estimated complexity, and decoding the first portion of the video at the determined voltage and frequency.

摘要： Segments for a video are transmitted in payload units with a supplemental enhancement information (SEI) message within which is embedded display adaptation information that may be employed to control display brightness and thereby reduce power consumption during display of the respective segment. The display adaptation information includes at least a maximum pixel brightness that may be used to scale pixel brightness to maximum and correspondingly reduce backlighting for liquid crystal displays, or to adjust the supply voltage for OLED displays. The display adaptation information may optionally include a minimum pixel brightness, a pixel histogram step size, and an indicator of scaling method.

摘要： Segments for a video are transmitted in payload units with an extended network abstraction layer unit (NALU) header or supplemental enhancement information (SEI) message within which is embedded display adaptation information that may be employed to control display brightness and thereby reduce power consumption during display of the respective segment. The display adaptation information includes at least a maximum pixel brightness that may be used to scale pixel brightness and correspondingly reduce backlighting for liquid crystal displays, or to adjust the supply voltage for OLED displays. m pixel brightness is set to a level saturating a portion of the pixel histogram without perceptual loss to the viewer, resulting in further reduction of power consumption.

摘要： A method and apparatus for managing data in a software defined network (400). The apparatus is configured to receive control information related to a source node (502a) and a target node (502b) from a plurality of network devices (404,406,412) in the software defined network (400). The apparatus is also configured to identify a route (510-522) for data forwarding between the source node (502a) and the target node (502b) based on the control information. The apparatus is also configured to request data forwarding to the plurality of network devices according to the route. The source node (502a) or the target node (502b) can be at least one of a user equipment (UE) (300), and a cellsite node (474) including at least a base station (404).
