The invention discloses a method for transferring desktop information of a PC to a video communication terminal. The method includes steps as follow: capturing desktop information of a PC after having received a triggering command, and converting a format of the PC desktop information into a format of the a video communication terminal; encoding the converted desktop format in a mode ensured by the local video communication terminal; sending the coded bit stream to the local video communication terminal; receiving the said coded bit stream by the local video communication terminal, and transferring to a remote video communication terminal after being processed. The invention also discloses an apparatus for transferring desktop information of a PC to a video communication terminal that includes a background processing-device and a terminal processing-device. The background processing-device includes a capture driver, a capturing device, an image converter, a background encoder and a background bit stream sender; the terminal processing-device includes a terminal bit stream transmitter. With the method and device, any desktop information of a PC can be transferred to a remote video communication terminal integrally and clearly.

A method for realizing multi-picture, including: A. Multipoint Control Unit (MCU) creates an indicator containing multi-picture information for each of the terminals and sends the indicators to the terminals; B. each terminal receives the indicator, encodes a source picture depending on the information in the multi-picture information indicator, and inserts said multi-picture information indicator into a sub-bitstream and transmits the sub-bitstream to the MCU; C. when receiving the sub-bitstreams from the respective terminals, the MCU combines the sub-bitstreams into a composite bitstream and sends the composite bitstream to a display terminal; D. the display terminal receives the composite bitstream, extracts the sub-bitstreams from the composite bitstream, and decodes the sub-bitstreams depending on the multi-picture information indicators of the sub-bitstreams and combines the decoded sub-pictures into a multi-picture output. The present invention reduces the cost and greatly enhances multi-picture transmission and combination capability thus to implement transmission and combination of sub-pictures.
