Abstract: An image processing method and apparatus are disclosed. The method includes: obtaining a video stream, where the video stream includes a first frame of image, a second frame of image, and a third frame of image that are adjacent in time sequence; decoding the video stream to obtain a first alignment frame, a second alignment frame, and at least one residual between the first frame of image, the second frame of image, and the third frame of image; generating at least one residual frame based on the at least one residual; performing super resolution processing on the second frame of image based on the at least one residual frame, the first alignment frame, and the second alignment frame to obtain a second frame of image obtained after super resolution. According to the method, an edge detail can be enhanced, thereby improving video picture quality without increasing hardware costs.

Abstract: Embodiments of the present invention provide a packet loss processing method, a destination network node device and a mobile transmission network system. The method includes: receiving, by a destination network node device, data sent through at least two transmission quality measurement protocol links by a source network node device, where service priorities of the at least two transmission quality measurement protocol links are different; and determining a reason for occurrence of packet loss according to packet loss ratios and the service priorities on the at least two transmission quality measurement protocol links when it is detected that packet loss occurs on the at least two transmission quality measurement protocol links. Technical solutions of the embodiments of the present invention for distinguishing bit error packet loss and congestion packet loss are high in efficiency.

Abstract: The present application discloses a radio frequency system, includes a detection device, at least one antenna line device, and an antenna that are sequentially connected in series by using a radio frequency channel. Each of the at least one antenna line device is configured to: receive a detection signal from the detection device or a previous antenna line device connected in series to the antenna line device; and add device information of the antenna line device to the received detection signal, and send, to the antenna or a next antenna line device connected in series to the antenna line device, the detection signal to which the device information is added. The detection device obtain device information of each of devices connected in series on a radio frequency line, to determine whether a connection relationship between the devices is correct, and determine a specific port location at which an error occurs.
