Adaptive jitter buffer management, e.g., for playout of packetized data transmitted over a network. Playout delay is iteratively adjusted based on changing network traffic characteristics by varying the release threshold in a jitter buffer. The adjustment is carried out by evaluating three quantities: (1) average packet transit time over the network; (2) jitter of the packet transit time; and (3) additional waiting time due to the presence of out-of-sequence packets. This invention reduces negative effects of jitter and/or transmission irregularities, such as late arrival of packets and out-of-sequence packets, while maintaining relatively low playout delay and relatively high quality of service.

The invention discloses a sampling GPR method of continuous anomaly detection in a collecting data flow of an environment sensor, and belongs to the technical field of data monitoring of environment sensors. The sampling GPR method of the continuous anomaly detection in the collecting data flow of the environment sensor is used for solving the problem that anomaly detection can not be conducted in real time, wherein the problem is caused by the fact that data calculation amount is large in data flow anomaly detection of a traditional environment sensor. The sampling GPR method of the continuous anomaly detection in the collecting data flow of the environment sensor is based on a prediction-model method, a prediction model is built through historical data, the mean value and the confidence interval of current data are obtained, a current data value is compared with the confidence interval, and the current data value is regarded as exceptional data if the current data value exceeds the confidence interval. According to the sampling GPR method of the continuous anomaly detection in the collecting data flow of the environment sensor, less historical data are needed, algorithm operation efficiency is improved, and input training data are not required to be provided with category tags. The sampling GPR method of the continuous anomaly detection in the collecting data flow of the environment sensor can detect an exceptional situation in a self-adaptive mode according to real-time arrival data, and is applied to continuous exceptional data detection in collecting data flow of the environment sensor.

A content-dependent scan rate converter with adaptive noise reduction that provides a highly integrated, implementation efficient de-interlacer. By identifying and using redundant information from the image (motion values and edge directions), this scan rate converter is able to perform the tasks of film-mode detection, motion-adaptive scan rate conversion, and content-dependent video noise reduction. Adaptive video noise reduction is incorporated in the process where temporal noise reduction is performed on the still parts of the image, thus preserving high detail spatial information, and data-adaptive spatial noise reduction is performed on the moving parts of the image. A low-pass filter is used in flat fields to smooth out Gaussian noise and a direction-dependent median filter is used in the presence of impulsive noise or an edge. Therefore, the selected spatial filter is optimized for the particular pixel that is being processed to maintain crisp edges.
