摘要： Content can be advantageously customized by use of an accompanying rich media file that characterizes segments in the content file. To perform such customization, the rich media file undergoes parsing (e.g., examination) to identify a location for an overlay in the least one segment of the content file. Thereafter, an overlay is inserted into the at least one content segment. In practice, the overlay is inserted to block objectionable material in the content segment, but the overlay can be inserted to add material, such as to insert an advertisement or a sub-title for example. Inserting the overlay can include physically overlaying a cover layer onto one or more frames of the content segment to add information or block objectionable material in the content segment.

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.
