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.

A generic hardware and software platform for electronic devices in multimedia, graphics, and computing applications are disclosed. In one embodiment, the generic hardware platform includes one of a single bus link or multiple bus link. Further, the generic hardware platform includes one or more of a power module, a processor, a memory device, a security engine, an environmental device, a man machine interface (MMI) device and a medical device coupled to the one of the single bus link or multiple bus link via an associated interface. Furthermore, the generic hardware platform includes one or more of a storage device, a video/image input device, a video/image output device, an audio input device, an audio output device, a location, position, and motion device, a wireless communication channel, a wired communication channel, and a timer coupled to the one of the single bus link or multiple bus link via an associated interface.

A system and method for providing in-built audio/video bridge on endpoints capable of video communication over Internet protocol (IP) is disclosed. In one embodiment, a modified video communication terminal (MVCT), one or more of video communication terminals (VCTs) and one or more of voice over IP communication terminals (VoCTs) are connected via an IP network. Further, the MVCT includes an audio/video bridging module (AVBM). Furthermore, the audio/video bridging of incoming audio/video streams from the one or more of VCTs and VoCTs via the IP network is enabled by the AVBM for conferencing the participants.
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.
