    Abstract: The present invention discloses a method for generating media information, a terminal, a server, and an adaptive streaming system. Media code streams of m types of code rate, which are generated by an AHS system, are divided into h groups, and tracing codes are separately embedded into code stream segments of each group. The tracing codes embedded into the code stream segments, and code stream group information are stored in a media presentation description MPD file. In a downloading process of a terminal, tracing of an end user that downloads media data is implemented.

    Abstract: A travelling-wave tube includes an input apparatus, a control circuit, an electron gun, a slow-wave circuit, and an output apparatus. The input apparatus may be configured to receive a radio frequency signal, and feed the radio frequency signal into the slow-wave circuit. The control circuit may be configured to determine a quantity N of electron beams and currents of the N electron beams, and control the electron gun to emit the N electron beams. Further, the slow-wave circuit may perform beam-wave interaction with the N electron beams, to amplify power of the radio frequency signa, and because the slow-wave circuit works in a saturation region, electronic efficiency of the travelling-wave tube can be greater than or equal to a first threshold. The output apparatus may output an amplified radio frequency signal.

    Abstract: This application discloses a linkage apparatus, a camera module, and an electronic device. The linkage apparatus is used in the camera module with continuous zooming, and includes a base, and a first carrier and a second carrier that are slidably connected to the base. A first positioning element is disposed on the base, a first sensing element and a second positioning element are disposed on the first carrier, and a second sensing element is disposed on the second carrier. The first sensing element is disposed opposite to the first positioning element, to detect a location of the first carrier relative to the base. The second sensing element is disposed opposite to the second positioning element, to detect a location of the second carrier relative to the first carrier. A movement relationship between the first carrier and the second carrier is set as an associated movement.
