Abstract: 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 artefact 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 artefacts and an artefact/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 artefacts, the received subjective quality score and the artefact/quality score database.

Abstract: A hinge assembly and a portable electronic device are provided. The portable electronic device includes a lid, a main body, and a hinge assembly. The hinge assembly pivotly connects the lid to the main body. The hinge assembly includes a pivot element, a torsion spring, and a hinge brace. The pivot element is formed on the lid and partially and rotatably received in the main body. The torsion spring is assembled between the lid and the main body. When the lid is in a closed position with respect to the main body, the torsion spring becomes constricted and accumulates potential energy. When the lid is opened from the main body, the potential energy of the torsion spring is released to drive the lid to rotate to an open position with respect to the main body. The hinge brace is attached to the main body for blocking an excessive rotation of the lid with respect to the main body.

Abstract: 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.

Abstract: 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.
