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.

摘要： A particular implementation receives a bitstream and derives parameters from the bitstream. The parameters include quantization parameters, content unpredictability parameters, ratios of lost blocks, ratios of propagated blocks, error concealment distances, motion vectors, durations of freezing, and frame rates. Using these parameters, a compression distortion factor, a slicing distortion factor, and a freezing distortion factor are estimated respectively for distortions resulting from video compression, a slicing mode error concealment, and a freezing slicing mode error concealment. The distortion factors are then mapped to a composite video quality score. For applications with limited computational power, the estimation of distortion factors can be simplified. In particular, the compression distortion factor, the slicing distortion factor, and the freezing distortion factor can be predicted from quantization parameters, ratios of lost blocks, and durations of freezing, respectively.

摘要： Accuracy and efficiency of video quality measurement are major problems to be solved. According to the invention, a method for accurately predicting video quality uses a rational function of the quantization parameter QP, which is corrected by a correction function that depends on content unpredictability CU. Exemplarily, the correction function is a power function of the CU. Both QP and CU can be computed from the video elementary stream, without full decoding the video. This ensures high efficiency.

摘要： A user terminal device, a server device, a system and a method for assessing quality of media data are described. The user terminal device is used for extracting artifact features from the media data and for communicating the features to the server device which is then used for determining a quality score using the artifacts and an artifact/quality score database accessible by the server device. The score, transmitted to the user terminal device, is presented to a user from which a subjective quality score and a request for re-determination are received which the user terminal device communicates to the server device. This in turn is used for re-determining the quality score and for transmitting back the re-determined quality score wherein the quality score is re-determined using the received artifacts, the received subjective quality score and the artifact/quality score database.
