Abstract:
1. A method of realizing multi-picture, comprising the following steps: A. a Multipoint Control Unit creating an indicator containing multi-picture information for each of the terminals and sending the indicator to each of the terminals; B. each of the terminals receiving said indicator, encoding a source picture depending on the information in the multi-picture information indicator, and inserting said multi-picture information indicator into a sub-bitstream and transmitting the sub-bitstream to the Multipoint Control Unit; C. when receiving the sub-bitstreams from the respective terminals, the Multipoint Control Unit combining the sub-bitstreams into a composite bitstream and sending the composite bitstream to a display terminal; D. the display terminal receiving the composite bitstream, extracting the sub-bitstreams from the composite bitstream, decoding the sub-bitstreams depending on the multi-picture information indicator of the sub-bitstreams, and combining the decoded sub-pictures into a multi-picture output.
