Description

CROSS-REFERENCE TO RELATED APPLICATION

This application is a continuation of and claims priority to U.S. patent application Ser. No. 11/700,330, entitled “Coordinated Media Control System,” which is incorporated herein by reference in its entirety.

BACKGROUND

Media devices are commonly used to facilitate communications between remote users. Exemplary media devices include fax machines, video cameras, telephones, printers, scanners, displays, personal computers, microphones, speakers, and other suitable devices for facilitating communications. Each media device typically includes its own interface and control system. Further, different brands and models of the same type of media device may differ in their interface and control systems. The functionality available may also differ even on the same type of media device.

Communications between remote users are typically enhanced by utilizing a plurality of media devices together in a collaborative environment. However, coordinating among the differing interface and control systems of the various media devices can be, amongst other things, complex, time-consuming, and expensive. Having differing interface and control systems can further interfere with the accuracy, expediency and efficiency of the communications process.

For these and other reasons, there is a need for the present invention.

SUMMARY

One embodiment of the invention provides a coordinated media control system. The coordinated media control system includes a node manager, a device control system, and a device. The node manager is operatively connected to a first node. The device control system is operatively connected to the node manager. The device is operatively connected to the device control system. The node manager is configured to establish and coordinate media streams for transmitting media from the device to a second node or for receiving media to the device from the second node.

DETAILED DESCRIPTION

In the following Detailed Description, reference is made to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration specific embodiments in which the invention may be practiced. In this regard, directional terminology, such as “top,” “bottom,” “front,” “back,” “leading,” “trailing,” etc., is used with reference to the orientation of the Figure(s) being described. Because components of embodiments of the present invention can be positioned in a number of different orientations, the directional terminology is used for purposes of illustration and is in no way limiting. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. The following detailed description, therefore, is not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.

Embodiments of the invention provide systems and methods for establishing an environment employing a plurality of devices. In one embodiment, the environment is a collaborative environment. In one embodiment, the plurality of devices are locally and remotely coordinated by establishing media stream correspondences between the devices.

As used herein, the term “media” includes text, video, sounds, images, or other suitable digital data capable of being transmitted over a network.

As used herein, the term “node device” includes processor-based devices, input/output devices, or other suitable devices for facilitating communications between remote users. Examples of node devices include fax machines, video cameras, telephones, printers, scanners, displays, personal computers, microphones, and speakers.

As used herein, the term “node” includes any suitable environment or system configured to transmit and/or receive media via one or more node devices. In one embodiment, the environment is a collaborative environment, which enables remote users to share media across one or more node devices. A collaborative environment will enable, for example, a presenter to simultaneously give a multimedia presentation to an audience not only in the presenter's location but also in one or more remote locations. The collaborative environment may further enable the audience in the remote locations to participate in the presentation as the audience in the presenter's location would participate (e.g., ask questions to the presenter).

As used herein, the term “event” refers to a connection of a plurality of nodes such that one or more node devices of one node are configured to transmit media to and/or receive media from one or more node devices of another node.

FIG. 1 illustrates a block diagram of a coordinated media control system 100 in accordance with one embodiment. Coordinated media control system 100 includes a first node 102a, a second node 102b, an event manager 104, and an event data storage 106. First node 102a and second node 102b are collectively referred to as nodes 102. While the illustrated embodiment depicts two nodes 102, coordinated media control system 100 includes any suitable number of nodes 102 in other embodiments.

First node 102a includes a graphical user interface (GUI) 108a, a device data storage 110a, a node manager 112a, a device control system 114a, and a node device 116a. Second node 102b includes a graphical user interface (GUI) 108b, a device data storage 110b, a node manager 112b, a device control system 114b, and a node device 116b. GUI 108a and GUI 108b are collectively referred to as GUIs 108. Device data storage 1108 and device data storage 110b are collectively referred to as device data storages 110. Node manager 112a and node manager 112b are collectively referred to as node managers 112. Device control system 114a and device control system 114b are collectively referred to as device control systems 114. Node device 116a and node device 116b are collectively referred to as node devices 116.

Event manager 104 is operatively connected to event data storage 106 and node managers 112. Node manager 112a is operatively connected to GUI 108a, device data storage 110a, and device control system 114a. Node manager 112b is operatively connected to GUI 108b, device data storage 110b, and device control system 114b. Node device 116a is operatively connected to device control system 114a and node device 116b, which is operatively connected to device control system 114b. In one embodiment, one or more components of coordinated media control system 100 are operatively connected via one or more suitable computer networks, such as a local area network (LAN) or the Internet. In one embodiment, one or more components of coordinated media control system 100 communicate via one or more suitable network protocols, such as TCP/IP.

In one embodiment, event manager 104 is configured to manage information describing the state of an event. Examples of information describing the state of an event include the identity of nodes 102 and node devices 116 participating in an event, the relationships among nodes 102 and node devices 116, the intent or manner in which each node 102 and node device 116 is participating, and the capabilities of each node 102 and node device 116. In another embodiment, event manager 104 is also configured to instruct nodes 102 to operate in accordance with event management policies stored in event data storage 106.

Event management policies include any suitable conditions or restrictions for creating, executing, and terminating an event. Examples of event management policies include the number of nodes 102 permitted to join an event, the types of nodes 102 permitted to join an event, and data relating to the progress of the event (e.g., duration of an event, available bandwidth). The operation and configuration of event manager 104 is described in greater detail in Ser. No. 11/497,886 entitled “System and Method for Managing Virtual Collaboration Systems,” filed Aug. 2, 2006 and assigned to the same assignee as the present application, the disclosure of which is incorporated herein by reference.

Node managers 112 are configured to establish and coordinate media streams for transmitting media between node devices 116. As illustrated in the embodiment of FIG. 1, node managers 112 operate in accordance with instructions received from attendees via GUIs 108 and in accordance with the event management policies provided by event manager 104. In one embodiment, GUIs 108 provide a user interface enabling attendees to create, execute, and terminate events between nodes 102. GUIs 108 include any suitable input/output devices, such as a mouse and a display, for communicating with node managers 112. In one embodiment, each of node devices 116 further includes its own GUI (not shown).

In one embodiment, GUIs 108 provide attendees with a natural and logical environment for coordinating node devices 116. In particular, GUIs 108 allow attendees to operate node devices 116 for sharing media streams without the need for specific knowledge of the interface for each node device 116. For example, if the attendee in first node 102a desires to share image data recorded from an overhead camera in first node 102a, the attendee is able to control functions of the camera, such as zoom and focus, through GUI 108a without the need for specific knowledge regarding the brand or model of the camera. Further, the attendee is unburdened with the complications of establishing media connections among a plurality of node devices 116 with different interfaces. For example, if an attendee in first node 102a desires to share image data from an overhead camera in first node 102a to a display in second node 102b, the attendee is able to select the overhead camera and the display through GUI 108a.

In one embodiment, node managers 112 configure and control node devices 116 in accordance with node information stored in device data storages 110. Node information includes any suitable configuration and control information specific to the particular nodes in which device data storages 110 are located. Examples of node information include the state of the nodes 102 (e.g., online or unavailable), event participation configuration and control data (e.g., the manner and priority in which a node 102 can participate in an event), node device configuration and control data (e.g., command sequences for operating node devices 116), and user interface data (e.g., the default language of GUIs 108). In one embodiment, only node manager 112a or other components within first node 102a is permitted to access device data storage 110a. In one embodiment, only node manager 112b or other components within second node 102b is permitted to access device data storage 110b.

In one embodiment, the node information related to first node 102a and node device 116a is stored in device data storage 110a and managed by device control system 114a. In one embodiment, the node information related to second node 102b and node device 116b is stored in device data storage 110b and managed by device control system 114b.

In one embodiment, device control systems 114 provide node managers 112 with an abstracted interface to node devices 116. The control commands are “abstracted” because the user does not need to have specific knowledge (e.g., brand, model, firmware version) of node devices 116 to operate them. Device control systems 114 are described in greater detail in the commonly-owned U.S. patent application Ser. No. 11/700,331 entitled “Device Control System,” which is incorporated herein by reference in its entirety.

FIG. 2 illustrates a flow diagram illustrating one embodiment of a method 140 of establishing and sharing media from (receiving media to) first node 102a to (or from) second node 102b. With reference to FIG. 1, using GUI 108a, an attendee selects (at 142) a node device 116a in first node 102a for which to share media from (or receive media to) node device 116a. In one example, if the attendee desires to share the image from an overhead camera, the attendee selects a camera icon among a plurality of icons shown on GUI 108a. The attendee selects (at 144) a node device 116b in second node 102b for which to receive the media from (or to send the media to) node device 116a. In one example, if the attendee desires for a display to show an image from an overhead camera shared by node device 116a, the attendee selects a display icon among a plurality of icons shown on GUI 108a.

The attendee shares (at 146) the media between the selected node devices 116. In one example, the attendee selects a share icon among a plurality of icons shown on GUI 108a to share the media from node device 116a to node device 116b. The attendee configures (at 148) node device 116a. In one example, the attendee adjusts the focus and zoom of an overhead camera using GUI 108a. In one embodiment, the attendee configures (at 148) node device 116 prior to sharing (at 146) the media. In another embodiment, the attendee configures (at 148) node 116 while sharing (at 146) the media.
