  • Publication number: 20140253601
    Abstract: 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.

  • Publication number: 20140136727
    Abstract: A method includes calculating a complexity value for each segment or version of multimedia content. The multimedia content has multiple versions associated with common content and different encoding parameters, and each version is divided into segments. The method also includes adaptively streaming the multimedia content to a client device based on at least some of the calculated complexity values. The complexity value for each segment or version is calculated by summing multiple operation complexity values defining complexities of operations for decoding the segment or version. The operation complexity values could include values for a bit parsing operation, a buffer initialization operation, an intra-prediction operation, an inverse quantization and transform operation, a reference block fetch operation, a fractional interpolation operation, and in-loop deblocking operation, a sample adaptive offset correction operation, an adaptive loop filtering operation, and a de-ringing filtering operation.

  • Publication number: 20130278834
    Abstract: Segments for a video are transmitted in payload units with an extended network abstraction layer unit (NALU) header 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.

  • Publication number: 20130278642
    Abstract: 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. The maximum 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.
