| 20100162092 | APPLYING EFFECTS TO A VIDEO IN-PLACE IN A DOCUMENT - An application program utilizes a decoding sub-system and a three-dimensional (3D) rendering sub-system to apply effects to a video in-place in a document. The program configures pixel shaders for use with a rendering device for applying pixel-level effects to the decoded frames of the video, generates meshes, and pre-renders textures for use in implementing effects. When a request is received to play back the video in-place in the document, a decoding surface and a rendering surface are allocated. The decoding sub-system decodes frames of the video and copies the decoded frames to the decoding surface on one thread. A separate thread copies decoded frames from the decoding surface to a texture and from the texture to the rendering surface. The rendering device utilizes the pixel shaders, meshes, pre-computed textures, and other data to render the frames of the video to a rendering target. | 06-24-2010 |
| 20100215280 | RDP BITMAP HASH ACCELERATION USING SIMD INSTRUCTIONS - Systems, methods and computer readable media are disclosed for a vectorized tile differencing algorithm for a remote desktop protocol (RDP). A server executes a CBC-variant vectorized hash algorithm that is used to produce a big key that identifies the tile, and keeps track of these big keys. Where a serial version of the algorithm operates on a single portion of the image at once—such as 32 bits—the vectorized algorithm operates on a plurality of these portions simultaneously. Where the server identifies that a tile has already been sent to a client via RDP because it has a second big key that matches the big key, it sends the big key to the client—which caches received tiles—and the client uses it to access the proper tile for display. Where the server identifies that a tile has not already been sent to the client, it sends the client the tile. | 08-26-2010 |
| 20100228871 | TEAR-FREE REMOTE DESKTOP PROTOCAL (RDP) DISPLAY - Systems, methods and computer readable media are disclosed for reducing the tearing of display data received across a communications network. A server determines at least two logically related drawing orders in an order heap and warps those orders with a begin marker and an end marker. It sends those wrapped orders across the communications network to a client. The client receives those orders and renders them to a shadow buffer. When the client processes the end marker, it moves the drawing orders in the shadow buffer to a client display surface. | 09-09-2010 |
| 20100254616 | IMAGE COMPRESSION ACCELERATION USING MULTIPLE PROCESSORS - Systems, methods and computer readable media are disclosed for accelerating the compression of images on a multi-processor computer. In an embodiment, an image is divided into a plurality of slices, each slice having the same width as the image. These slices are provided to a work manager that maintains a thread for each processor. The work manager assigns each slice to a thread for processing in an efficient manner (such as the thread corresponding to the first available processor), and when an indication that the slice has been compressed for each slice is received, the work manager assembles the compressed image. | 10-07-2010 |
