Abstract: The method includes: after obtaining an image of a to-be-operated device by using a target application, the electronic device may send the image of the to-be-operated device to a server corresponding to the target application. Then, the server may obtain an operation model of the to-be-operated device based on the image of the to-be-operated device, and the server sends the operation model of the to-be-operated device to the electronic device. Next, the electronic device may display a user operation interface corresponding to the operation model, and the user may perform an operation on the user operation interface. The electronic device sends an operation event corresponding to the second operation of the user to the server, and the server processes the operation event corresponding to the second operation.

Abstract: A video playing method and a terminal device and method including starting, by a terminal device, at least two playing instances based on an operation instruction of a user, where each of the at least two playing instances corresponds to a video display window, and where the video display window includes a first video display window and a second video display window, playing first channel content in the first video display window and playing second channel content in the second video display window according to a display mode selected by the user, detecting an operation gesture of the user on the first video display window or the second video display window, and adjusting playing modes of the first channel content and the second channel content according to the operation gesture of the user and a current display mode.

Abstract: A channel playing method and a related device, to collect statistics on channel playing information of a terminal and update a mosaic channel bitstream and a played image based on a statistical result. In this way, subchannels of a mosaic channel are updated based on the playing information of the terminal, and the terminal device plays an adapted mosaic channel. The method performed by a video server includes: obtaining channel playing statistical information of a terminal; updating subchannels of a mosaic channel based on the channel identifiers in the channel playing statistical information; and sending a channel generation instruction to a mosaic generator to instruct the mosaic generator to generate a mosaic channel bitstream that includes the updated subchannels and channel identifiers of the updated subchannels, and the channel generation instruction includes the channel identifiers of the updated subchannels.

Abstract: Embodiments of the present invention disclose a method, a device and a system for ordering a pay program, which aim to play an ordered program automatically once a user's payment is completed. The method includes: sending an order request to an EPG server; receiving an amount should be recharged sent by the EPG server; sending a redirection request to the payment platform, where the redirection request carries an HTTP URL provided by the EPG server, and the HTTP URL is saved by the payment platform; receiving a redirection response sent by the payment platform, where the redirection response carries the HTTP URL; redirecting to the order processing page of the pay program according to the HTTP URL; obtaining an RTSP URL from the order processing page; and requesting a CDN to play the pay program according to the RTSP URL.
