Abstract: Systems and methods are disclosed that facilitate real-time information exchange in a multimedia conferencing environment. Data Client(s) facilitate data collaboration between users and are maintained separately from audio/video (AV) Clients that provide real-time communication functionality. Data Clients can be remotely located with respect to one another and with respect to a server. A remote user Stand-in Device can be provided that comprises a display to present a remote user to local users, a digital automatic pan/tilt/zoom camera to capture imagery in, for example, a conference room and provide real-time information to an AV Client in a remote office, and a microphone array that can similarly provide real-time audio information from the conference room to an AV Client in the remote office. The invention further facilitates file transfer and presentation broadcast between Data Clients in a single location or in a plurality of disparate locations.

Abstract: Systems and methods are disclosed that facilitate rapidly warping a two-dimensional image using integer math. A warping table can contain two-dimensional floating point output pixel offset values that are mapped to respective input pixel locations in a captured image. The warping table values can be pre-converted to integer offset values and integer grid values mapped to a sub-pixel grid. During warping, each output pixel can be looked up via its integer offset value, and a one-dimensional table lookup for each pixel can be performed to interpolate pixel data based at least in part on the integer grid value of the pixel. Due to the small size of the lookup tables, lookups can potentially be stored in and retrieved from a CPU cache, which stores most recent instructions to facilitate extremely rapid warping and fast table lookups.

Abstract: The invention facilitates transmission of information across text communication channels in real time. A conversion component is provided that converts binary data into binary-as-text format, and parses converted binary data into packets for serial transmission over an SIP-connected messaging system via a text channel in the SIP-connected messaging system and/or an SIP information side-band channel.

Abstract: A software enabled, matrix switch is presented wherein a scalable plurality of inputs, coupled to media content sources, provide media content which is recursively routed through select media processing object(s) coupled to a scalable plurality of matrix switch outputs in accordance with a user-defined media processing project.

In one embodiment a media engine includes a topology loader module that receives a partial topology from another module associated with the media engine. The topology loader implements logic operations that convert a partial topology into a full topology, which may be returned to the media engine for presentation of the media stream(s) to a user.

Abstract: In one embodiment, a system receives an indication to generate a filter graph representing a user-defined development project. Media sources that are to be used in the user-defined development project are identified and a programming grid is establishing that incorporates a user's editing instructions. A matrix switch filter is generated based, at least in part, on the programming grid. The filter graph is assembled and comprises a plurality of individual filters. Buffer size and attribute characteristics are negotiated between an input/output of the matrix switch filter and an input/output of adjacent filters. Negotiated buffers are utilized to communicate media content between the matrix switch filter and adjacent filters by sharing a common buffer between inputs and outputs.

Abstract: Methods and systems for managing multiple inputs that are capable of competing or contending for a particular or primary output are described. In one embodiment, the multiple inputs are managed through the use of a software-implemented matrix switch object, and an associated data structure that is used to program the switch object and resolve contention issues between the inputs. The matrix switch object can process the multiple inputs to provide a primary output. One implementation of the switch object uses virtual input and output pins to receive and provide data streams. One specific embodiment is used in connection with multi-media editing software that enables users build or define their own editing multi-media editing projects that incorporate multiple different user-selected clips, in the form of digital data streams, into an integrated project. Each clip can be defined in terms of one or more digital data streams, e.g. video and audio streams.

Editing projects can have one or more tracks, and each track can be associated with one or more data stream sources that can have effects or transitions applied on them. Compositions can be nested inside one another and provide an economical way for complex editing manipulations to take place.
