Abstract: A method, a system, a terminal and a server for switching from a video live stream to video-on-demand data are provided. The method includes: sending, by a terminal, a video acquisition request for a target video to a server; acquiring, by the server, video data of the target video from a live stream of the target video in response to the video acquisition request, and storing the acquired video data of the target video; sending, by the terminal, a video editing request for the target video to the server; performing, by the server, non-linear editing on the video data of the target video in response to the video editing request; and storing, by the server, the edited video data as video-on-demand data of the target video.

Abstract: A RF signal choking device includes: a first port electrically receiving direct current, RF signals, and antenna interface standards group (AISG) signals from a base station; a blocking capacitor being provided for blocking the direct current and the AISG signal and transmitting the RF signal; a second port connected to the other end of the blocking capacitor, for outputting the RF signal; a first inductor, one end of which is connected to the first port, for transmitting the AISG signal and the direct current; a modulator, one end of which is connected to the other end of the first inductor, for processing the AISG signal; a third port, which is connected to the other end of the modulator, for outputting the processed AISG signal; and a second inductor, one end of which is connected to the second port and the other end of which is connected to the ground.
