Abstract: A method may include receiving functional model information regarding a set of functional blocks associated with a functional model. The functional model may include a streaming algorithm for exchanging streaming data. The method may include receiving architectural model information regarding physical devices included in a target device from a hardware-software co-design platform. The physical devices may include a software based processing device and a hardware based processing device. The method may include mapping the functional blocks to the physical devices to allow the streaming data to be communicated between the software based processing device and the hardware based processing device. The method may include generating a streaming interface to model communication of the streaming data between the software based processing device and the hardware based processing device.

Abstract: A system for modifying video including a source of a filter stack specifying filter operations to be carried out on a video clip, a filter registry of filter functions including information on filter operations that can be carried out by the filter functions, and a filter planner that receives the filter stack and accesses the registry in order to generate a filter plan specifying filter functions to be used in carrying out the filter operations specified in the filter stack.

Abstract: A method for displaying data representative of a video stream by providing frames containing progressively-encoded frame data. These frames represent a portion of the video stream. A selected extent of the frame data contained in each frame is fetched, and a video stream corresponding to the selected extents is displayed.

Abstract: The media manipulator is a middle layer between the clients and the remote data servers is the common client-server organization. It transforms the network into a more flexible three-tiered configuration. Requests generated by the clients for media objects from media resources are routed to the media manipulator. It processes the requests and determines if the media objects may be found locally, either cached in the media manipulator itself or in the local data servers. When the media objects are obtained, the media manipulator can be used to perform operations on those objects such as format translations, to apply protective mechanisms for the clients, to speed communications between the remote servers and the clients, or perform compute operations for the clients. In one example, a parser of the manipulator searches for images in the media objects so that service devices can be called to perform data compression or pornography detection on the images.
