A system and method for a media processor separates the functions of topology creation and maintenance from the functions of processing data through a topology. The system includes a control layer including a topology generating element to generate a topology describing a set of input multimedia streams, one or more sources for the input multimedia streams, a sequence of operations to perform on the multimedia data, and a set of output multimedia streams, and a media processor to govern the passing of the multimedia data as described in the topology and govern the performance of the sequence of multimedia operations on the multimedia data to create the set of output multimedia streams. The core layer includes the input media streams, the sources for the input multimedia streams, one or more transforms to operate on the multimedia data, stream sinks, and media sinks to provide the set of output multimedia streams.

Media scrubbing using a media processor

Methods and systems of processing multi-media editing projects are described. In one embodiment, a request for one or more multi-media files is generated on a user computer that comprises part of a network where multi-media files are maintained in a network-accessible location. The file or files are intended for use in a multi-media editing project. The request is intercepted and software executing on the user computer ascertains whether one or more of the requested multi-media files are located on the user computer. If the file or files are located on the user computer, they are retrieved and used. If a file or files are not locally available, the file or files are retrieved from the network-accessible location. In one embodiment, a multi-media file locator object is configured to intercept network-bound requests for multi-media files and determine whether requested files are locally maintained on a user computer. A list associated with the file locator object can reference local file directories on the user computer where multi-media files are stored, or have been stored in the past. Whenever a user retrieves a multi-media file from the network and saves it locally, if the directory in which the file is stored is not referenced on the list, the file locator object can update the list to include the new directory. If the file locator object attempts to locally find a multi-media file but cannot, the user can be prompted to point to a directory where they have stored the file. The list is then updated to reflect this new directory, and the directory is checked on subsequent searches for multi-media files. Accordingly, when a request for a multi-media file is received, only those local directories that are or have been associated with multi-media files can be checked.

Methods and systems for processing multi-media editing projects

In one embodiment, a network-bound request for a multi-media file is intercepted to determine whether the file is located locally on a user computer. If the file is located on the user computer, it is retrieved. If the file is unavailable locally, the file is retrieved from a network-accessible location. In another embodiment, a file locator is configured to intercept network-bound requests for multi-media files and determine whether the files are available locally using a list that includes local file directories where files may be stored. When a user retrieves a file from a network and saves it in a directory, if the list does not include the directory, the list is updated to include the directory. If the file locator cannot find the file locally, the user is prompted to select a directory where the file is stored, and the list updated to include the directory.

Media processing technologies

A system is presented including a plurality of sources, and an interface, selectively coupled to the plurality of sources, to generate and implement a development project of processing chains, wherein the interface dynamically loads a processing chain for each of the plurality of media sources at a point during the execution of the project when the chain is required, and wherein the interface is configured to unload at least a subset of the chains when they are not required.

A timeline source is described. In an implementation, a method includes examining a plurality of nodes within a media timeline, where at least two of the nodes reference respective media. The media timeline is for exposure over an API. The media timeline is divided into one or more presentations. Each presentation describes rendering of the media for a particular interval of time.

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.

A multimedia processing system and methods provide flexibility and modularity by separating data flow information from maintaining of stream state for multimedia components. The system includes a media processor component to process received media data, a media session to determine a timeline for events to occur for performing media processing and a topology loader component to load a topology that describes a flow for the received media data to enable processing via an extensible symbolic abstraction of media objects. The topology loader ensures that events described in the topology occur. The system also includes core layer components such as media sink components to determine a media stream for output from the multimedia processing system and a media source component coupled to supply media data for processing. The topology created in the system symbolically provides data flow information, independent of maintaining a streaming state of control information.

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.

System and related interfaces supporting the processing of media content

A method comprising generating a source chain for use in a development project, generating an identifier which is uniquely assigned to the source chain, and caching the source chain when it is not currently required in the development project. As execution of the development project continues, or during a subsequent project, if the source processing chain is required, it is retrieved from cache.
