Abstract: Provided a method and device for playing and processing a video based on a virtual desktop. The method comprises: a terminal receives a original code stream of a video file to be played currently, wherein the original code stream is sent to the terminal by a virtual desktop system after the virtual desktop acquires the original code stream; and the terminal plays the video file according to the original code stream. The disclosure avoids or reduces the occupation of Central Processing Unit (CPU) resources of a virtual machine host, and achieves smooth playback of video files.

Abstract: Disclosed is a method for transmitting media data, comprises: acquiring streaming media data of a media file that a terminal requests to play; when it is determined that the terminal supports a media format of the streaming media data, sending the streaming media data to the terminal, and the terminal playing the streaming media data; when it is determined that the terminal does not support the media format of the streaming media data requested to be played, converting the media format of the streaming media data into a media format supported by the terminal; and sending the converted streaming media data to the terminal, and the terminal directly playing the converted streaming media data. Also disclosed is a virtual desktop server. The present invention can effectively save the CPU resources of the virtual desktop server.

Abstract: An implementing method for removing duplication protection for multimedia messaging service interworking forwarding message and multimedia messaging service interworking gateway. The method determines whether to return response message according to the different value of the acknowledgement request field of the request signaling. Using the SMTP-interactive-status code as a criterion, when the acknowledgement request field is set to be “NO”, requesting not to return the response message, and when the acknowledgement request field is set to be “YES”, requesting to return the response message. Determine whether the forwarding is successful by determining whether the SMTP-sending-status code returned by the response signaling is received according to the replying status of the response signaling.
