A system and method for ensuring buffer compliance in a moving picture experts group 2 (MPEG2) transport stream (TS) system is disclosed. In one embodiment, a plurality of encoded audio/video (A/V) streams is categorized into a first group and a second group. Further, interleaving bits and a number of bytes to be sent are computed for each encoded A/V stream in the first group and the second group, respectively. Furthermore, an encoded A/V stream is selected based on the computed interleaving bits and number of bytes to be sent, respectively. In addition, one or more TS packets are generated by packetizing data in one or more frames in the selected encoded A/V stream based on program clock reference (PCR) and decode time stamp (DTS) associated with the one or more frames to ensure buffer compliance in the MPEG2 TS system.

A system and method for demultiplexing an MPEG-2 Transport Stream (TS), is disclosed. In one embodiment, a method of demultiplexing an MPEG-2 TS includes receiving the TS via a system interface, managing the TS via a TS manager, and managing parsing of the TS via a parser manager. Further, the method includes creating a media data stream by parsing the TS via one or more parsers within the parser subsystem, and creating a plurality of decodable units from the media data stream via a framer.

A design for a unified session signaling system for use in multimedia communications is disclosed. In one embodiment, a method includes interfacing, via an application interface, with an associated application and a session, tracking, via a call state/session manager, a call state and session properties across multiple calls associated with the session, managing, via a server interoperation module, registration and proxying services associated with the session, managing, via a basic SIP services module using a third party SIP stack, a basic set of SIP services associated with the application and the session, and determining and advertising, via a media negotiator module, media capabilities of devices associated with the session. The method may also include managing, via an additional SIP services module using the third party SIP stack, a set of additional services associated with the session.

An architecture, system and method for an RTP streaming system is disclosed. In one embodiment, a method includes developing multiple standalone modules, developing application programming interfaces associated with the standalone modules, and tying together the standalone modules to form a subsystem associated with a streaming application and with a network. The method further includes integrating standalone modules including an RTP module, an RTCP module and a payload interface, associated with any one of a server mode and a client mode. The method also includes managing a streaming session associated with media streams via an RTPSS manager, adding the media streams to a stream manager. For each media stream of the streaming session: the method includes performing packetization services in the server mode and de-packetization services in the client mode, and performing server-mode related services in the server mode and client-mode related services in the client mode.

A memory manager for a system, a system that includes the memory manager and a method of using thereof are provided. The memory manager manages memory allocations in at least a memory. The memory manger comprises, a first unit configured for receiving a plurality of requests from one or more components of one or more applications of a system. The memory manager also includes a second unit configured for optimizing memory allocations for the plurality of requests.

A method of managing a processing system that has at least one processor, uses the steps of: measuring MCPS (million cycles per second) utilization in the at least one processor; estimating a cycle count requirement for an algorithm on least one processor based on measured MCPS utilization; and, estimating an ability to run multiple applications on the at least one processor by assessing MCPS requirements and estimated cycle count requirement. Measurement of the MCPS utilization is preferably done by using the steps of: choosing a critical path in the processor, e.g., by taking hard real time requirements into consideration; measuring time taken for processing along said critical path; and, calculating MCPS requirements along said critical path using the measured time taken and a current processor clock speed. The inventive method has application in 802.11 MAC. Also described is a programmed storage medium to execute the described method.
