In a real-time video transmission system for a cellular-connected unmanned aerial vehicle (UAV) based on an adaptive bitrate provided by the present disclosure, an on-board computer is loaded and configured on the UAV, such that the UAV can provide multiple video streams with different bitrates for retrieval. A client with a bitrate adaptation unit is set up, allowing the system to adjust the bitrate of the video stream according to network conditions in each time interval. Intranet penetration and port mapping are implemented on the cloud server, enabling the client to obtain, from the cloud server, the real-time video stream captured by the UAV. The present disclosure allows a remote user to watch, through a cellular network, the real-time video stream captured by the UAV.

Embodiments of the present invention, relating to the field of desktop cloud applications, provide a desktop-cloud-based media control method and a device, so as to reduce a bandwidth occupied by transmission of a multimedia data stream in a media control process. The method includes: acquiring, by a client, a multimedia data stream, displaying the multimedia data stream, receiving a control instruction sent by a cloud server, and performing a corresponding control operation on the displayed multimedia data stream according to the control instruction. The method embodiment is used for media control.

Desktop-cloud-based media control method and device

A dual band communication method and a wireless local area network (WLAN) device, First determining a service type of a service in a switching period according to a preset policy, where the switching period includes one first timeslot in which a first radio frequency (RF) channel works and one adjacent second timeslot in which a second RF channel works, and determining, according to the determined service type and a preset service quality requirement corresponding to the service type, maximum duration of the switching period in which the service quality requirement is met, and when time division multiplexing (TDM) is performed on a baseband processor, controlling the switching between the first RF channel and the second RF channel according to the maximum duration, hence actual duration of the switching period is less than or equal to the maximum duration.

Dual band communication method and WLAN device

Embodiments of the present invention provide a dual band adaptive concurrent processing method and apparatus. In the embodiments of the present invention, by using statistical information of services at first and a second frequency bands in the Nadjustment period, performance of the services at the frequency bands in an adjustment period may be acquired. Based on the statistical information, and a quality of service (QoS) requirement that the services at the two frequency bands need to meet, a second coefficient of proportionality between timeslots occupied by the services at the two frequency bands in the (N+1)adjustment period may be determined, so that switching control on first and second channels may be performed in the (N+1)adjustment period according to the determined second coefficient of proportionality.
