Abstract: Embodiments can provide a service orchestration method and apparatus, and a server. In the service orchestration method, a service flowchart can be obtained. The service flowchart may include a plurality of operation model identifiers and a logical connection relationship among the plurality of operation model identifiers. The logical connection relationship may be an execution sequence in the service flowchart. In this method, a scheduling parameter corresponding to each operation model identifier can be obtained. When the scheduling parameter indicates a live network resource for executing the service flowchart, a live network status can be obtained by using a control plane. Based on the obtained live network status, whether the live network resource can be obtained can be verified. When the verification succeeds, based on the logical connection relationship and the scheduling parameter that corresponds to each operation model identifier, executable code for executing the service flowchart can be generated.

Abstract: Embodiments of the present invention provide a method for synchronous playback by multiple smart devices, and an apparatus. A first device acquires frame synchronization information at intervals of a preset time, and sends the frame synchronization information to one or more second devices, where the frame synchronization information is frame information of a frame to be played by the first device or frame information of a frame that the first device starts to play currently; and after learning the frame synchronization information sent by the first device, the second device adjusts frame resources played by itself. Because the multiple smart devices that perform synchronous playback are generally in one local area network, a transmission delay of frame information from the first device to the second device can be ignored, thereby improving a synchronization effect among the multiple smart devices.

Abstract: A computer-implemented method for increasing the image resolution of a digital image is provided. The method includes performing bicubic upsampling of the digital image to generate a base high-resolution (HR) image. The digital image is converted from a red-green-blue (RGB) color space to a Luma (Y), Chroma Blue Difference (Cb), and Chroma Red Difference (Cr) (YCbCr) color space to generate a low-resolution (LR) residual image. A plurality of convolutional layers of a neural network model is applied to the LR residual image to convert it to a plurality of HR residual sub-images corresponding to the digital image. An HR image corresponding to the digital image is generated using the base HR image and the plurality of HR residual sub-images.
