Abstract: PROBLEM TO BE SOLVED: To provide automatic re-authentication. SOLUTION: Upon successfully authenticating a client device with a server system, the client device and server system share auto-reconnected data. Upon subsequently losing and re-establishing communications with the server system, the client sends an auto-authenticate request to the server. The auto-authenticate request includes a session verifier that is based at least in part on the shared auto-reconnected data. The server validates the session verifier. If the validation is successful, the server automatically re-authenticates the client device. COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To provide a data compression for communication in a terminal service environment. SOLUTION: Data is compressed by finding an index in a LUT matching with an initial sequence in the data. The LUT includes a plurality of entries and each entry is found by using specific one in a plurality of indexes. Each entry is a reference to show whether or not the corresponding index is located in a history buffer, and if it is located, it becomes the reference to show one or plural positions of the corresponding index in the history buffer. When the corresponding entry of a matching index refers to a plurality of positions, a sequence having the matching sequence each position is compared with a sequence in the data including the initial sequence. The matching sequence is led from a comparison based on a length and the position of the sequence existing in each of a plurality of positions. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: Techniques are disclosed for acceleration techniques for improved image remoting. A rolling 2D hash of a first image sent to a client is computed. When the server has a second image to send to the client, it calculates a rolling 2D hash of the new image. It also calculates "pivot points" for the images based on the rolling 2D hashes. Based on the pivot points, it determines possible matching hash windows between the two images that correspond to window moves or scrolls. Where a match is confirmed, it determines whether a "larger" a larger matching rectangle exists between the two images. It then instructs the client to display the matching rectangle that exists in the first image that the client has in the appropriate location in the second image, thereby saving the bandwidth requirements to re-transmit it to the client.

Abstract: 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.

Abstract: 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.

Abstract: Techniques are disclosed for a user-mode based remote desktop protocol (RDP) encoding architecture. A user mode desktop application and user mode virtual channel application run in user-mode session space. Virtual channel data from the virtual channel application is marshaled and sent to a RDP encoder process in user-mode system space. There it is converted to RDP protocol data units (PDU) and sent to a remote client across a communications network. Graphics data from the desktop application is sent to a display driver in kernel-mode session space and then to a graphics reflector that marshals the graphics data and sends it to the RDP encoder for a similar transformation.

Abstract: Embodiments provide for efficient encoding and rendering of remote graphic displays by applying one or more of the following: (1) field encoding for identifying fields of a graphics set such that commonalities of various fields across different graphics languages are identified; (2) resource caching, which treats heterogeneous resources in a homogeneous way when it comes to storing them; (3) determining the type of encoding for remoting items within a graphics set based upon the types of compression mechanisms supported by a remote device; (4) improving responsiveness by rendering with partially sent resources; (5) a mechanism for determining what portions (if any) of a graphics set should be sent to a remote device and in what order; and (6) use of dedicated resources already on a remote device in order to eliminate the transfer of a resource between a local device and the remote device when rendering such resource.
