Abstract: A new image formation model for descattering different from the previous works based on atmospheric scattering model is established. It can provide a corresponding physical explanation for each scattering environment, illustrate a relationship between a light source position and scattering conditions and solve the problem of scattering removal under non-uniform illumination. Firstly, a dark angle of a camera is removed by an integrating sphere; then, a pure scattering part is found by an improved dark channel-like prior method; and finally, a zenith angle, an azimuth angle, an extinction coefficient and other related physical quantities are calculated according to the light attenuation and backscattering distribution of a scattering medium to eliminate the backscattering and light attenuation. Theoretically, the model can be used in any uniform scattering medium, such as underwater and fog environments, and works well in high-density media.

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: A method and a system for allocating delivery reports are disclosed in the present invention. A Service Provider (SP) sets a message identifier MSGID1 in a multimedia message and submits the multimedia message containing the MSGID1 and destination numbers to a server in a multimedia messaging service gateway (MMSG), the server sets a message identifier MSGID2 in the multimedia message, and forwards the multimedia message containing the MSGID2 and the destination number to a multimedia messaging service center (MMSC); the MMSG parses the corresponding server generating the MSGID2 according to the MSGID2 in the delivery report returned by the MMSC, and forwards the delivery report to the server creating the MSGID2. By adopting the method and system of the present invention, it ensures that the delivery reports returned by the MMSC are evenly allocated to the servers in the MMSG, the load balancing of the servers can be realized.

Abstract: A multimedia messaging service center (MMSC) and method for caching mobile phone newspaper thereof are disclosed. The MMSC comprises a memory module, a mobile phone newspaper message processing module and a network attached shortage (NAS) module. In this method, after receiving a multimedia message, the MMSC decodes the multimedia message and determines whether the multimedia message is a mobile phone newspaper message; if it is, then the MMSC transmits the message body of the multimedia message to the mobile phone newspaper message processing module. The mobile phone newspaper message processing module determines whether the same message body has been saved in the memory module; if it is, then said message body is discarded, otherwise, said message body is saved into the memory module. The processing efficiency of the MMSC and the user experience are improved by the present invention.

Abstract: A services cloud system and a service realization method are provided. In the services cloud system, a service processing module processes a core service logic part of an application service and calls a data processing module. The data processing module calls a tool and algorithm library of an open service logic module to process the service data and stores the results into a distributed file system module. The system and service realization method implement unified service products and save network resources.

Abstract: The present invention discloses a method and a system for application layer link control. The method comprises: judging whether the number “a” of links which have been established between an exterior IP and a multimedia messaging service gateway (MMSG) in current granularity is less than a threshold number “A” of links for establishing a connection with the MMSG in the current granularity (S1); if it is determined to be “yes”, subtracting the “a” from the “A” to obtain a threshold number “B” of links for establishing a connection with the MMSG in a next granularity (S2), wherein B=A?a; and otherwise, obtaining the threshold number “B” of links for establishing a connection with the MMSG in the next granularity, wherein B=0, and rejecting a request that the exterior IP initiates to establish a connection with the MMSG in the next granularity.
