    摘要: A technique and method provide virtual N-way video conferencing to participants having IP stations/videophones, which have limited processing capacity, by auto-selecting a limited subset of the participants for video display and restricting the rest of the participants to voice-only mode which requires reduced processing capability. The method uses a virtual n-way conferencing module (VNCM) to provide the video conferencing, and an auto caller select module (ACSM) for causing selective video display. Some of the participants might have VoIP terminals instead of IP videophones. The invention includes a technique, e.g., by using a video transmission control module (VTCM) for reducing the bandwidth requirement of IP videophones by signaling the participants in voice-only mode not to transmit the video information in bandwidth-constrained situations. Also taught herein is an article comprising a storage medium having instructions thereon which when executed by a computing platform will result in execution of the method.

    摘要: An improved decoding process as applied to MPEG AAC decoders of the type that use codebooks, reduces redundant traversing steps while finding the location of a specific binary stream codeword in the codebook. To this end, the codebooks are divided into a plurality of node-tables, each table corresponding to a node. From the number of bits “k” in a given node-table, the decimal value of the first “k” bits in a binary stream to be decoded is ascertained and compared with the decimal value of the maximum code word in the given node-table. The comparison is used for the identification of the location of the codeword in the node-tables to assist in decoding without unnecessary traversing of all the nodes in the codebook.
