A media player may be adapted to manage presence information distribution and access to facilitate media communication between compatible devices. Devices connecting in an ad-hoc or other network topology include a plurality of presence settings that determine how or if the device appears to be available for communication to other devices over the network. Additionally, the presence settings identify other, specific devices or groups of devices that may communicate with a device. By comparing the presence settings of a sending device with the settings of a receiving device, the receiving device may determine a presence state for all devices within communication range.

Media device presence management

A media player is adapted to organize and display nearby media device information between communicating media devices before a complete connection is established. A nearby media device receives a message that is either generally or specifically sent from another media device. The nearby device determines whether the sending media device is blocked and whether to accept the message. The nearby device accepts the message if it originates from a compatible source. If the message is accepted, the nearby device sends an acknowledgement message containing a unique device name and a device status to the sending device. The sending device then displays the unique device name and status.

Nearby media device tracking

An improved application sharing system and method are described wherein a display of shared information is constructed such that application artifacts that are of no use to the viewer are not displayed to the viewer. In this way, a greatest possible portion of a viewing area can be used to display document content rather than such artifacts. In an embodiment, the functionality of reducing the display in this manner is engageable and disengageble by a viewing user. In a further embodiment of the invention, the functionality of reducing the display is automatically engaged and disengaged based on actions of a sharing user with respect to the shared information.

Document viewing mechanism for document sharing environment

An improved application sharing system and method are described wherein an application sharing viewing display is modified to increase the likelihood that a viewing user is able to see without scrolling the entirety of a window of interest displayed by a sharing user on a sharing machine. The scale of the viewer representation of the window of interest may be substantially continuously varied so as to best account for the particular size of the available display area at the viewing machine. In a further embodiment of the invention, the viewer's attention may be focused by filtering of the shared display material to visually enhance the current window of interest.

Application sharing viewer presentation

A server computer hosts one or more application programs that are accessed by a client computer. Higher-level graphics commands describing graphics images are received from the application programs. The server computer determines whether the client computer is able to generate graphics using the higher-level graphics commands or generates graphics using relatively lower-level graphics commands. The server computer sends higher-level or relatively lower-level graphics commands depending on whether the client computer generates graphics using higher-level or relatively lower-level graphics commands.

Remote client graphics rendering

In order to minimize the delay of the video images viewed by a network conference attendee, an intelligent buffering process (IB process) selectively discards video frames from at least one point, and in an embodiment, many network points, such as at 'in' and/or 'out' buffers of clients, servers, routers, etc. Packets of video frame data arrive at a buffer, which can fill to a predetermined limit if the packets cannot be forwarded due to delays or slow connections. To forward the most current video images, old frames in the buffer are discarded rather than forwarded. In a particular embodiment, when the buffer is full, the next arriving delta frame packet is discarded. To avoid distortion, each subsequent delta frame is discarded until a new key frame eventually arrives. If the buffer is still full when the key frame arrives, the buffer is purged and the new key frame is added.

Techniques relating to enabling a graphical window modification command to be applied to a remotely generated graphical window are described. In one instance, a process detects a user command to modify a remotely generated application graphical window in a remote terminal session. The process determines whether to initiate the user command at a local machine upon which the remotely generated application graphical window is displayed or at a remote machine which generated the remotely generated application graphical window.

An improved application sharing system and method are described wherein shared window data is treated according to different sets of rules depending upon the fraction of the shared window data that corresponds to the actual shared window. In this manner, occlusions of a shared window on a sharer display may be disguised or handled by a viewer display to minimize the impact of the occlusion on a viewing user, providing a more consistent and less confusing viewer experience.

Application sharing user interface improvements

Embodiments of the invention, are directed to synchronizing the presentation of windows between two computing systems. A client computing system participates in a terminal server session with a server computing system. Both computing systems identifying their own windows display information (e.g., client-side for local windows and server-side for remote windows respectively). The server computing system transmits its windows display information to the client computing system. The client computing system accesses the windows display information of the server computing system. The client computing system formulates combined ordering applicable to the presentation of both local and remote windows at the client computing system. The combined ordering is based on both the client side and the server-side windows display information. The client computing system presents windows in accordance with the formulated combined ordering. Additionally or alternatively, the client computing system transmits the formulated combined ordering to the server computing system.

Enabling a graphical window modification command to be applied to a remotely generated graphical window

An improved application sharing system and method allow sharing of documents on a per document basis rather than on a per application basis, in order to simplify the user experience and to provide a more secure sharing environment. A window marking method is used to construct a window list describing the shared and unshared status of various windows. In an embodiment of the invention, a viewer machine displays only a most recently active shared document window even when other windows are also marked as shared. In this way, a viewer's attention can be automatically focused on a current document of interest.
