A method and system of content delivery provide availability of at least two versions of content by delivering data for a first version of content, a difference data representing at least one difference between the first version and a second version of content, and metadata derived from two transformation functions that relate the first version and the second version of content respectively to a master version.

A system and method for compensating for average brightness dependency (ABD) differences between displays with and without average brightness dependency (ABD) includes color correcting source picture content on a reference display to output color corrected picture content. In addition, an ABD simulation process uses the color corrected picture content to simulate the display of content on the reference display. Subsequently, a compensation process receives the color corrected picture content and information from the simulation process and applies an ABD compensation characteristic to the color corrected picture content for correctly displaying the source picture content on a display with different ABD characteristics than the reference display.

A method and system for gamma adjustment for average power level dependency displays includes applying gamma controlled functions over a range of values at a plurality of average power levels (APLs) for a display. The gamma controlled functions include coefficients for reconstruction of the gamma controlled functions. Upon a change to an APL, interpolation is performed between the coefficients to predict a new gamma controlled function for the new APL.

Embodiments of a method, apparatus and system for providing display device specific picture content over a network architecture include at least one content server for storing a plurality of virtual model versions of the content respectively generated in accordance with a plurality of virtual device models. Each of the plurality of virtual device models has a virtual model specification (VMS) which controls at least one display feature. In one embodiment, the at least one content server engages in negotiations with at least one network attached unit to permit a selection of a particular one of the plurality of virtual model versions based on a comparison of at least one of the at least one display feature of the virtual model specification of at least one of the plurality of virtual device models against an actual display requirement included in an actual display specification of a particular display.

According to this method, successive iterations are launched according to the following steps:—1) the reproduction color device is set according to settings,—2) reference input colors are calibrated putting calibrated input colors,—4) reproduction quality rating value are calculated,—5) a reproduction quality criterion is applied to decide or not to go for another iteration with different settings. This method allows the optimization of the settings according to color preferences.

摘要:
Gamma information extracted from an input source is utilized to correct display gammas. Adjustment of display parameters is performed automatically based on the gamma information and obtained display characterization information. One instance utilizes gamma information such as, for example, gain, offset, and gamma, to automatically determine a corresponding brightness and/or contrast adjustment level of a display. In this manner, the output gamma can be adjusted to substantially match the input gamma.
