Various implementations address distortion and quality measurements related to, for example, freeze-with-skip and/or a freeze-without-skip events. In several implementations, information is accessed indicating that a first and second set of one or more consecutive pictures are not to be displayed. A first and second indicator are determined. In one such implementation, the first and second indicators indicate an amount of distortion across one or more types of distortive effects that result from displaying substantially a first, or second, same picture during a display time for the first, or second, set of pictures. The first and second indicators are combined in a non-linear manner. In another such implementation, the distortion is associated with a given type of distortive effect, from among multiple types of distortive effects, and the first and second indicators are combined for the given type of distortive effect. |

1. A method comprising:
accessing information indicating that a first set of one or more consecutive pictures from a video sequence are not to be displayed; accessing information indicating that a second set of one or more consecutive pictures from the video sequence are not to be displayed, the second set being separate from the first set in the video sequence; determining a first indicator, the first indicator indicating an amount of distortion associated with a given type of distortive effect, from among multiple types of distortive effects, that results from displaying the video sequence with substantially a common first picture displayed during a display time for the first set of pictures; determining a second indicator, the second indicator indicating an amount of distortion associated with the given type of distortive effect that results from displaying the video sequence with substantially a common second picture displayed during a display time for the second set of pictures; and combining the first indicator and the second indicator to produce a combined indicator of distortion for the given type of distortive effect. |
