    • 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.
    • 一种实现多画面的方法,包括:A.多点控制单元(MCU)创建一个包含每个终端的多画面信息的指示符,并将指示符发送到终端; B.每个终端接收指示符,根据多图像信息指示符中的信息对源图像进行编码,并将所述多图像信息指示符插入到子比特流中,并将子比特流发送到MCU; 当从各个终端接收子比特流时,MCU将子比特流组合成合成比特流,并将合成比特流发送到显示终端; D.显示终端接收复合比特流,从合成比特流中提取子比特流,并根据子比特流的多图象信息指示符对子比特流进行解码,并将解码的子图像合并成多比特流, 图片输出。 本发明降低成本并大大提高了多画面传输和组合能力,从而实现子画面的传输和组合。

    • A preparation process of polyimide aerogels that composed of aromatic dianhydrides and aromatic diamines or a combined aromatic and aliphatic diamines is described. Also descried is a process to produce carbon aerogels derived from polyimide aerogel composed of a rigid aromatic diamine and an aromatic dianhydride. Finally, the processes to produce carbon aerogels or xerogel-aerogel hybrid, both of which impregnated with highly dispersed transition metal clusters, and metal carbide aerogels, deriving from the polyimide aerogels composed of a rigid aromatic diamine and an aromatic dianhydride, are described. The polyimide aerogels and the polyimide aerogel derivatives consist of interconnecting mesopores with average pore size at 10 to 30 nm and a mono-dispersed pore size distribution. The gel density could be as low as 0.008 g/cc and accessible surface area as high as 1300 m2/g.
