Abstract: Techniques perform data backup. Such techniques involve: in response to a first storage node to be switched to a second storage node, determining whether there is an ongoing data backup operation between the first storage node and a third storage node; and in response to the ongoing data backup operation between the first and third storage nodes, ceasing the data backup operation. The second storage node is used for backing up data of the first storage node in real time and the third storage node is used for backing up the data of the first storage node periodically. Accordingly, colliding operations can be prevented, system resource can be saved and processing efficiency can be improved.

Abstract: Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. In some examples, an apparatus for video decoding includes processing circuitry. The processing circuitry receives coded information of a current coding tree unit (CTU) from a coded video bitstream, and determines a context model for a split flag associated with a current block within the current CTU at least partially based on split information of a corresponding block in a reference CTU for the current CTU. Then, the processing circuitry determines the split flag based on the context model, and decodes the current block based on the split flag that is determined based on the context model.

Abstract: A device may operate within a specified frequency band within a specified coverage area of a wireless cellular network served by a cell. The device may monitor, during a cell-specific paging window, paging messages transmitted by the cell within the cell-specific paging window to devices operating within the specified coverage area and targeted to receive paging messages. The device may enter an idle state if the monitoring indicates that the paging messages do not include a respective paging message intended for the device. If the monitoring indicates that the paging messages include a paging message intended for the device, the device may process the paging message. Furthermore, the device may indicate to the cell, when attaching to the cell, whether the device has a capability to support standalone operation within the specified frequency band. If the indication is that the device does not support such standalone operation, the cell may not issue paging messages to the device.

Abstract: The present invention relates to a video processing apparatus, method, and system. In particular, in accordance with one embodiment, high-speed video is divided into at least two sub-videos having a frame rate lower than that of the input video, during which metadata for synchronization of the two sub-videos which corresponds to frames of each sub-video is generated, and inserted into the respective sub-videos for video processing in parallel. During the parallel processing of the sub-videos, the system monitors and controls the synchronization of the process and, upon completion of the sub-video processing, use the metadata to re-assemble the sub-videos into one high-speed video stream for output, the output video having the same frame rate as the received input video stream.

Abstract: A method for determining whether a testing specimen is supplied to a testing system, which includes a reaction tank in which the testing specimen reacts; a light source for emitting testing light into the reaction tank from one side of the reaction tank; and a photoelectric sensor that is placed on the side of the reaction tank opposite to the light source for receiving the testing light traveled through the reaction tank and that converts the received testing light into an electrical signal. The amount of the testing specimen to be added into the reaction tank is set so that the level of the testing specimen is above the light path of the testing light while the reaction tank is cleaned. Whether the testing specimen is supplied is determined based on the presence of change of the electrical signal output from the photoelectric sensor.

Abstract: Innovations in intra-picture prediction with multiple candidate reference lines available are described herein. For example, intra-picture prediction for a current block uses a non-adjacent reference line of sample values to predict the sample values of the current block. This can improve the effectiveness of the intra-picture prediction when the reference line of sample values that is adjacent the current block includes significant capture noise, significant quantization error, or significantly different values (compared to the current block) due to an occlusion.
