摘要： 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.

摘要： Two dimensional interpolation techniques are used to compensate for time-varying channel gain H in an OFDM system. The channel gain can be reasonably estimated at various times and at various frequencies due, for example, to the use of pilot tones. These channel estimates are used to estimate the channel gain at other times and/or frequencies by two-dimensional interpolation, interpolating first with respect to time (e.g., with respect to a symbol index s) and then with respect to frequency (e.g., with respect to a sub-carrier index c).
