摘要： A macroblock in a video sequence may be undecodable because the corresponding compressed data is lost or the syntax is out of synchronization. An undecodable macroblock may be concealed using error concealment technique. The level of initial visible artifacts caused by undecodable macroblocks may be estimated as a function of motion magnitude, error concealment distance, and/or residual energy. The initial visible artifacts may propagate spatially or temporally to other macroblocks through prediction. Considering both initial visible artifacts and propagated artifacts, levels of overall artifacts may be estimated for individual macroblocks. The visual quality for the video sequence can then be estimated by pooling the macroblock level artifact levels.

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： In video coding, prediction of P- and B-frames is based on reference frames, which are indicated by reference picture lists. Scalable video coding (SVC) requires this for both, base-layer and enhancement-layer. The invention describes a decoding process for reference picture list construction for spatial enhancement layer. With just one flag of syntax modification, it provides simpler and direct reference lists construction process. By using this, complicated RPLR and other syntaxes can be skipped, and the RPLR process for spatial enhancement layer can also be avoided. The process also can be used as for error concealment when the spatial enhancement layer slice is lost.

摘要： Packetized video data with a base-layer and at least one enhancement-layer organized in a GOP structure may contain packet loss errors. A method for detecting such errors includes the steps of reading header information relating to a layer, generating a scheme or selecting a predefined scheme according to the header information. The scheme can be made up of a display order number, and/or a number of reference frames and temporal level for the frames of the respective layer. The method can then extract from received video data frames the display order number, and/or the number of reference frames and temporal level parameters, and detect that one or more frames or packets are missing. The received parameters are compared with the parameters of expected frames according to the scheme and a missing packet or frame is determined by a mismatch between received and expected parameters.

摘要： A method of online predicting maintenance of an apparatus is disclosed. Using an optical emission spectroscopy (OES) positioned on the apparatus and the change of emission spectrum intensity detected by the OES in the process, according to the detected results, measuring the parameter in the process, the function relation between the process parameter and spectrum intensity is acquired. A control threshold is decided by the processing requirement to the apparatus. When the parameter exceeds the control threshold, maintenance to the etching apparatus is engaged in order to avoid processing error caused by frequent shutdown or deficient maintenance which is estimated by experience, and hence decreasing the cost and increasing processing efficiency of substrates (such as silicon wafers) without changing apparatus and adding other online sensor, and improving production rate by avoiding waste substrates caused by error processing results. The method is suitable for semiconductor substrate etching maintenance of the apparatus and also other maintenance of the apparatus.
