A method and system for providing technical support for networked devices includes a first client component on a networked device having a conferencing application to enable communication exchange with a second client component. A server component is configured to distribute video and audio data streams to the first client component and the second client component in a conference session. A conference channel communication connection is established over which the video and audio data streams are carried between the first client component, the server component, and the second client component, and a back-channel communication connection is established for transmission of diagnostic and status information. A service call is managed by a service center dispatcher, who connects a technician client and a networked device client in a multi-party conference hosted on one of a plurality of load balanced servers.

Real-time one-button integrated support for networked devices

A secured network connection requires three authentication routines. A system access authentication routine requires a client network device to submit user authentication information to a network server. Upon successful user authentication, the network server creates a Client Service Access Pass, embeds this pass into a dynamic web page transmitted to the client device. A client application access authentication routine requires that the dynamic web page pass the Client Service Access Pass to an instantiated client application, which in turn submits it back to a service server on the network server for authentication. Upon success authentication, the network server destroys the Client Service Access Pass, creates a Media File Access Pass, and sends this pass to the client application. A media file access authentication routine requires the client application to submit the Media File Access Pass along with any file access requests to the network server.

A method for managing transactions associated with a persistent framework in a multi-thread environment is provided. The method initiates with associating each individual thread with an event queue. Then an event is added to a first event queue associated with a respective thread. The event is associated with a persistent object. Next, write access to the persistent object is prevented to all threads except the respective thread. Then, the event in the first event queue associated with the persistent object is executed. A computer readable media and a system capable of maintaining transaction states of persistent objects are also provided.

A communication protocol stack for enabling multimedia communication between communicating devices where multiple port communication data is tunneled through a single TCP port is provided. The communication protocol stack includes, at an application level, the capability to identify whether received communication data is for a communication port. If the received communication data is for the communication port, then the communication protocol stack includes the ability to forward identification data regarding the received communication data to a table in advance of forwarding the received communication data to a driver level of the communication protocol stack. A method, computer readable medium, and a system for tunneling port traffic through a single HTTP port are also provided.

Method and apparatus for tunneling data through a single port

Methods and systems for tunneling data associated with a packet based multimedia communication standard are provided. The method includes intercepting a library call associated with the multimedia communication standard in a modified TCP/IP stack and registering identification data associated with the library call. A modified Transmission Control Protocol/Internet Protocol (TCP/IP) header is appended over a pre-existing header of a data packet related to the identification data. The method also provides for transmitting the data packet having the TCP/IP header through a firewall. The TCP/IP header includes a TCP SEQ number and a TCP ACK number to provide a stateful connection.

A series of approved printers is associated with each of multiples utilities. A client user having a local printer must first identify the local printer as one of the approved printers. The client user may then gain access to the utilities having an association with the local printer. The utilities have access to multiple image sets. Each image set includes a thumbnail representation for quick selection, a screen representation for editing the image, and a printer representation for printing the image. The printer representation is of higher resolution than the screen representation, and the screen representation is of higher resolution than the thumbnail representation. Each utility is further associated with list of predefined, and unalterably, printer setting. When a print option is actuated, the utility conveys a list of predefined printer settings to a printer without requiring the client user to submit any printer preferences.

Printing sub-system for java and internet applications

A rotated representation of an image is printed by using a coordinate system to assign tile divisions to the image. The size of the tile divisions are selected to maintain their area equal to, or less, than a predetermined maximum. Each segment of the image, as defined by the tile delineations, is sent separately to a data processing unit for processing. The received tile is assigned new coordinate dictating its new target position on a printed page, and its relation to the other tiles. The tile is itself further rotated prior to being send to the printer.

An internet presentation system includes an internet accessible server that permits specific types of access to a target presentation file by selected remote users. Only users having purchase access to the target presentation file may submit a purchase order for a copy of the presentation file. Each user is further restricted to the type of copy, video or data, of the presentation that the user can acquire. Users having purchase permission are further divided into owner status and buyer status. Users having owner status may grant or revoke the purchase permission of non-owner status users. At least one owner status user is additionally designated a super-owner, and can grant and revoke the owner status of other users. The super-owner user may relinquish its super-owner status to any other user.

Methods and computer readable media for a software tool capable of subdividing programs into autonomous modules, where the modules enable a feature of the program, are provided. One exemplary method includes a computer implemented method for identifying modules of an executable program. The method begins with initiating the executable program. Then, the executable program is monitored as it is running. The monitoring of the executable program further includes, identifying interrelated classes for each of the modules where each of the modules correspond to a feature functionality of the executable program. Also included in the monitoring is generating a data structure for each module as the executable program is running. Here, the data structure defines the classes for each feature functionality.

Dynamic class packaging

Methods and an apparatus for downloading an application over a distributed network are provided. One exemplary method includes a computer implemented method executed by a general purpose computer, where the computer implemented method is capable of downloading an executable program from a networked storage to the general purpose computer. The method initiates with downloading a core module where the core module includes classes necessary to run an engine of the executable program. Then, the core module is installed which in turn module provides instant user functionality. The installed core module includes code for, requesting a class not associated with the core module, searching non-core modules of the executable program for the requested class, and downloading to the general purpose computer a non-core module containing the requested class while the executable program provides the user functionality.

Dynamic java class loading for application execution

A method of tracking modifications of specific program objects during the runtime of a computer program, facilitates the creation of general UnDo and ReDo operations, as well as the support of an object-specific UnDo operation. When an object is modified, the object is interrogated to collect information about it and how the modification may be undone. The collected information is stored in a highly unbalanced data-tree structure. Since the interrogation of an object is a characteristic of the programming language, and not necessarily a modification of the program being executed, the present method may be easily applied to different existing programs with minimal, if any, modification to the existing programs.
