ABSTRACT:
A modified modulation transfer function of a device is determined. The modified modulation transfer function includes intentional deviations from a nominal modulation transfer function of the device. A digital content object is modified based on the modified modulated transfer function to optimize playback of the digital content object on the device, and the modified digital content object is distributed to the device.
