Description

    REFERENCE TO RELATED PATENT APPLICATIONS
  • This application is a continuation of U.S. application Ser. No. 10/159,398, filed May 30, 2002 and entitled “Videoconferencing Bandwidth Management For a Handheld Computer System and Method,” and application Ser. No. 10/159,398, filed May 30, 2002 claims the benefit of U.S. Provisional Application No. 60/352,785, filed Jan. 29, 2002, and is related to U.S. Pat. No. 6,906,741, entitled “System For and Method of Conferencing With a Handheld Computer Using Multiple Media Types,” the entirety of which are herein incorporated by reference.
  • BACKGROUND
  • The present invention relates to methods and systems associated with mobile computing devices. More specifically, the present invention relates to a system for and method of videoconferencing via a handheld computer. More specifically still, the present invention relates to a system for and method of managing bandwidth for videoconferencing using a handheld computer.
  • Mobile communications and computation devices come in many forms, but conventionally the designs of such mobile devices make portability versus utility compromises. For example, a watch is conventionally a very portable device, but of limited functionality. If a watch included a 20-inch monitor, for example, attached to it, the user could display, navigate, and interact with the system to a very high degree. However, in this exaggerated example, the watch would be of very low portability. Handheld computer, personal digital assistant, and mobile phone designers, among others, are especially aware of this tradeoff, especially as these devices are being asked to include more functionality and asked to carry out more sophisticated tasks. However, although the mobile devices are being asked to provide more functionality, a paramount requirement is that the device remain easily portable.
  • There are challenges to providing a portable device with the ability to video conference. For example, bandwidth demands for videoconferencing can be high, particularly for small, wireless devices with limited computational power.
  • Conventional systems and methods exist which provide video content to handheld computers. For example, PACKETVIDEO of San Diego, Calif., provides an Internet service called PVAirGuide available at http://www.pvairguide.com or http://www.packetvideo.com. The PVAirGuide service provides for streaming video-on-demand where a user can select a channel, such as news, sports, or entertainment to view video information as would be available on broadcast television or radio. PVAirGuide also provides other mobile multimedia, including a live camera application called AirCam which feeds video from a video feed to a mobile device. For example, an AirCam live stream camera can provide live shots of traffic in central London to mobile devices throughout the world. Nevertheless, PVAirGuide's streaming video-on-demand and live camera displays provide only broadcast-television type of communications. Interactive videoconferencing is not available or possible.
  • Accordingly, there is a need for providing highly mobile devices (e.g., handheld computers, personal digital assistants, mobile phones, and watches) with functionalities conventionally limited to less portable devices that have more rich and usable computation, communication, or interaction capabilities. There is also a need for a mobile device to provide videoconferencing communications with other portable and/or non-portable devices. Further, there is a need for systems and methods which manage bandwidth during videoconferencing communications using mobile devices and/or handheld computers.
  • It would be desirable to provide a system and/or method that provides one or more of these or other advantageous features. Other features and advantages will be made apparent from the present specification. The teachings disclosed extend to those embodiments which fall within the scope of the appended claims, regardless of whether they accomplish one or more of the above-mentioned needs

Icon 155 toggles on an audio mode or audio option and allows the user to manipulate audio options, such as mute, etc.
  • An exemplary audio data option may be to present or provide audio data from a currently speaking participant during the video conference. The currently speaking participant may change from one videoconferencing participant to another depending on who is speaking at any one time. Such audio data may be delayed or streamed in a substantially real-time manner. Audio data may be used in a variety of data formats including Motion Pictures Experts Group (MPEG) formats including but not limited to MPEG3, among many other formats. Alternatively, another audio data option may be to provide audio data from all participants to the videoconferencing session. Yet another audio data option may allow the user to mute the microphone at the user's handheld computer such that audio data is not received or transmitted while mute is selected.
  • In a step 240, the user of the handheld computer can select a video data option to provide video communication from a selected source. A video data option can be selected using input function keys or icon 154 on the display of the handheld computer. As previously discussed, video sources during the video conference can include live video of participants of the video conference, video from other live cameras, pre-recorded video clips, or any other visual input. Such video data may be delayed or streamed in a substantially real-time manner. Video data may be used in a variety of formats including Motion Pictures Experts Group (MPEG) formats including but not limited to MPEG3, among many other formats. One video option may provide for the presentation or display of multiple windows at the handheld computer, each window display containing a different participant to the videoconferencing session. In yet another embodiment, a video option may be provided to show a currently speaking participant in one window and presentation slides or any kind of visual aid in another window. As such, participants in the video conference can view a speaker at the same time the speaker's presentation slides are viewed.
  • In a step 250, a user of a handheld computer, during, for example, a videoconferencing session, can select a text data option, using icon 152, to provide text data communicated from a selected source. As with the audio data option described with reference to step 230 and the video data option described with reference to step 240, the text data option can be selected using a function key or input icon 152 on the display screen. Once the text data option is selected, the user can select to present, generate, access, or receive any of a variety of different data sources. In an exemplary embodiment, text messages may be sent to all participants of a video conference or any subset of the participants. Further, text messages may be composed, sent and/or received during the transmissions of other types of data.
  • In a step 255, a user of a handheld computer, during a videoconferencing session can select an application data option, such as but not limited to the scribble option using icon 153, to provide application data communicated from a selected source. As with the audio data option, the video data option, and the text data option described, the application data option can be selected using a function key or input icon 153 on the display screen. Once the application data option is selected, the user can select to present, compose, access, and/or receive a combination of different data types available. For example, a participant to the video conference may desire to retrieve and/or compose application data, such as but not limited to a word processing document, a spreadsheet, a presentation slide show, an interactive sketch pad (scribble), or any other of a variety of different data files to use during the videoconferencing session.
  • Even though steps 230, 240, 250, and 255 are described with reference to FIG. 3 in flow diagram 200, steps 230, 240, 250, and 255 can be performed in any order, as many times, or not at all during a videoconferencing session. For example, a handheld computer user may change selections of audio (step 230) from mute to listen to all participants several times during the session. Similarly, the handheld computer user may change or toggle (or switch) between different video presentation views (step 240) during a session. For example, a user may want to switch back and forth between video images of different participants to the video conference. Further, a user may want to access any combination of data types available during the videoconference. For example, a user may wish to view and listen to a speaker, access a presentation document, and communicate with another participant via a text message, all during the conference call.
  • Once the videoconferencing session is over or the handheld computer user wants to end participation in the session, the videoconferencing session can be ended in a step 260. In an exemplary embodiment, the videoconferencing session can be ended by selection of an end icon or end function key on the handheld computer. Altematively, the videoconferencing session can be ended from a remote location. A wide variety of different options may be available at the end of a videoconferencing session. For example, an option may be provided to present to each participant of the videoconferencing session for the scheduling of a next meeting using the videoconferencing equipment. Advantageously, where multiple participants to the videoconferencing sessions are using a handheld computer, such as, handheld computer 100 described with reference to FIG. 2, possible times for a next videoconferencing session can be presented to the participants based on information stored in the organizer or calendar programs included in the memory of the handheld computer.
  • A wide variety of other applications may be available using the functionality present with the handheld computer. For example, still photos stored in the memory of the handheld computer can easily be presented during the video conference. Similarly, documents stored in the memory of a handheld computer can be shared, reviewed, and edited by any and/or all participants to the videoconferencing session. For example, a report requiring input from multiple employees in multiple locations can be compiled by the four employees while participating in a videoconferencing session. As such, the employees can discuss, face-to-face the report while compiling and editing the report at the same time using the data option in the videoconferencing session.
  • FIG. 4 illustrates a videoconferencing session 300 among at least four participants. In videoconferencing session 300, a conference participants using devices 310, 320, 330, and 340 can communicate an share information. Devices 310, 320, 330, and 340 are similar to handheld computer 100 described with reference to FIG. 2.
  • In an exemplary videoconferencing session, a participant using device 330 can sketch a graph 332 using device 330. Graph 332 can be selectively viewed and edited by other devices in the conference while continually hearing audio from any or all of devices 310, 320, 330, and 340. In lieu of viewing graph 332 as a working document, devices in the video conference can view graph 332 as a still, non-moving graph.
  • By way of example, at any moment during a videoconferencing session device 310 can show a video 314 of another participant in the conference while device 320 can show graph 332 accompanying the discussion while device 330 can show graph 332 and a video 334 of conference participants. At the same time, device 340 can show graph 332, videos 314 and 334 of conference participants, and additional information, such as, a web page 348.
  • Advantageously, each videoconferencing session participant can selectively control content displayed at a particular device. Further, participants can participate in the creation and editing of documents as if participants were all in the same room by using devices communicating in the videoconferencing session.
  • Referring now to FIGS. 6 and 7, videoconferencing images, audio and data can be transmitted in a variety of different modes. For example, a wireless ad hoc network (FIG. 6), or the Internet (or other communications network, FIG. 7), can be utilized to communicate the necessary data. Ad hoc networking provides for the interaction of multiple devices using spontaneous, wireless communication between devices. In yet another embodiment, a combination of an ad hoc network and the Internet or a corporate intranet can be used for communication of the video conference.
  • Referring now to FIG. 6, an ad hoc network 600 is depicted. Ad hoc network 600 includes a handheld or portable device A 610, a second handheld or portable device B 620, and a third handheld or portable device C 630. Devices 610, 620, and 630 are configured with wireless transceivers such that they are able to communicate with each other over wireless links 615, 625, and 635. In such a situation, a video conference may be set up by participants using devices 610, 620, and 630 and a fixed network infrastructure is not required. Devices 610, 620, and 630 may utilize any of a variety of communications protocols including IEEE 802.11 protocols, Bluetooth, and the like.
  • In another exemplary embodiment, a video conference system 700 is depicted in FIG. 7. Video conference system 700 includes a communications network 710, a server 720 coupled to communications network 710, and portable devices A 730, B 740, and C 750. Further, a device D 760, such as a desktop computer, may be coupled to communications network 710 in a wired fashion, such as over a telephone line, a digital subscriber line, a T1 line, an Ethernet connection, or the like. Device D may also be a participant in the video conference with participants 730, 740 and 750. In an exemplary embodiment, devices 730, 740 and 750 may have access to communications network 710 via access points that are coupled to communications network 710. Accordingly, a video conference may be set up between devices 730, 740, 750, and 760, all communications being directed over communications network 710 and to server 720. Server 720 receives communications from devices 730, 740, 750, and 760 and sends the communications back to the participants 730, 740, 750, and 760 after coordinating and directing the information.
  • In yet another exemplary embodiment, system 600 and system 700 may be combined in which some of the participants communicate in an ad hoc manner and others communicate over a fixed communications network such as network 710. Such a situation is a hybrid videoconferencing system utilizing both ad hoc networking and fixed communications network infrastructure.
  • Referring now to FIG. 8, a system 800 for videoconferencing is depicted. System 800 includes a plurality of videoconferencing servers X 802, Y 804, and Z 806. In an exemplary embodiment, servers X 802, Y 804, and Z 806 may include any number of servers. Servers X 802, Y 804, and Z 806 are also configured to communicate between each other via direct connections 808 or alternatively over any type of communications network. Conferencing system 800 includes a plurality of mobile devices including device A 810, device B 812, device C 814, and device D 816. Any of devices 810, 812, 814, and 816 may be handheld computers, such as but not limited to handheld computer 100 as depicted in FIG. 2.
  • In an exemplary embodiment, device A 810 may establish a communication link 820 with server X 802. Device B 812 may establish a communications link 822 with server Y 804. Device C 814 may establish a communications link 824 also with server Y 804, and device D 816 may establish a communications link 826 with server Z 806. In an exemplary embodiment if, for example, device B 812 and device C 814 have established links 822 and 824 with server Y 804, and device A 810 wishes to join the conference call and attempts to link to server Y 804, the connection may be redirected to server X 802 to establish link 820 because server Y 804 has determined that the load for server Y 804 is too substantial to handle other mobile devices. Similarly, if device D 816 attempts to join the conference call via server Y 804, the connection 826 may be redirected to be established with server Z 806. Servers X 802, Y 804, and Z 806 cooperate to distribute conferencing call information to all participants, 810, 812, 814, and 816, in the conference call via a number of links. For example, each of servers X 802, Y 804, and Z 806 transmit information to each of mobile devices 810, 812, 814, and 816. By utilizing multiple servers X 802, Y 804, Z 806, each transceiver must be used to receive less information than if only a single server were used. Further, servers X 802, Y 804, and Z 806 can be used to cooperate and distribute the task of coordinating and distributing information.
  • In yet another exemplary embodiment, a single server may be used to transmit information to all of the call participants, thereby freeing up the other servers to only receive information from the call participants. Accordingly, limited bandwidth using transceivers on servers X 802, Y 804, and Z 806 may be conserved by utilizing multiple servers in coordinating the conference call.
  • Referring now to FIG. 9, a process 900 utilizing the architecture of system 800 or similar architecture is depicted. In process 900, a communications session with a first server is established (step 910). The load of the first server is then checked (step 920). It is then determined whether the load of the first server is above a predetermined threshold (step 930). If the load of the first server is above a predetermined threshold a server is then automatically found that has available load or load capacity (step 940). However, if the load of the first server is not above a predetermined threshold, a communications session with the first server is established and maintained (step 950). Once the participants find an available server and are communicating with an available server, the participants may then communicate in a conference call (step 960). Once the conference call has been completed the conference call is then ended (step 970).
  • Referring again to FIG. 8, mobile devices 810, 812, 814, and 816 may communicate to servers X 802, Y 804, and/or Z 806 via any of a variety of communication methods including, but not limited to wireless communications methods such as IEEE 802.11 methods, Bluetooth methods, as well as through wired connections such as, but not limited to Ethernet connections. The tasks of managing a conference call using a plurality of mobile devices and at least some of which are connected over wireless links is distributed amongst a plurality of servers in an effort to conserve bandwidth, and/or create excess bandwidth that may be used by the mobile devices, especially in a situation in which the wireless connections or wireless transceivers which are being used by servers X 802, Y 804, and Z 806 may be substantially limited.
  • Referring now to FIG. 10, another exemplary process 1000 is depicted. Process 1000 is representative of a method of conserving communications bandwidth during a videoconferencing call that uses a plurality of mobile devices. Each mobile device has or is coupled to a camera for videoconferencing. In the embodiment depicted, mobile devices connect to a videoconferencing call (step 1010). As a particular participant in the video conference call wishes to take the lead in the videoconferencing call it may not be necessary to communicate video from all of the cameras to all of the devices. Accordingly, it may be desirable to conserve bandwidth by only communicating video from a mobile device of a particular user, for example a lead user. Therefore, a camera shutdown signal may be sent to selected user devices to shut down their cameras (step 1020). Once selected the cameras have been shut down, video signals may be sent from active cameras to user devices that are participants in the conference call (step 1030).
  • In yet still another exemplary embodiment, a process 1100 is depicted in FIG. 11. Process 1100 is used to maintain a conference call with multiple mobile devices that are configured to communicate more than one data type over a bandwidth limited service. Multiple user devices, such as handheld computers are connected to a conference call via a server (step 1110). Once the conference call has been established and all participants are on line, the server determines the available bandwidth for maintaining the conference call (step 1120). If requests for services are not available due to bandwidth limitations or due to other limitations, services that are available to conference call participants may be selectively disabled automatically (step 1130). For example specific participants may have access disabled to specific data types. For example, if bandwidth is too limited, participants in a conference call may have video access disabled and, audio access may be only made available to conference call participants. In an exemplary embodiment, the order in which services are disabled may be made in a hierarchy. For example, because video may be the most bandwidth intensive and may also be the most unnecessary of services, video may be the first to be disabled in the hierarchy. Further, in an exemplary embodiment, the user of a handheld device may be able to control the data types being used if the user is not satisfied with the present quality of service of the data types being received. For example, if video service is seen as jerky or undesirable in other ways, video service may be manually dropped by toggling icon 154, thereby disabling video service while maintaining other services, such as but not limited to audio. Such manual control by the user has an effect of conserving bandwidth.
  • An exemplary embodiment may utilize, be executed by, and/or be applied in a handheld computer including a processor such as but not limited to a Dragonball processor running at clock speeds of 33 MHz, 66 MHz, or other clock speeds, the Dragonball processor being available from Motorola Inc. of Schaumburg, Ill. An exemplary handheld computer may also include, but is not limited to, four (4) megabytes (MB) of flash read only memory (ROM) for storing BIOS information, operating system information, and other information. The flash ROM may be used to store, but is not limited to, any of a number of versions of the Palm operating system (OS) available from Palm, Inc. of Santa Clara, Calif. Further, an exemplary handheld computer may also include, but is not limited to, thirty-two (32) MB of synchronous dynamic random access memory (SDRAM) for storing program information, and other information to be used by the handheld computer. In an alternative embodiment, the handheld computer may also use a digital signal processor including an advanced RISC machine (ARM) processor available from Texas Instruments of Dallas, Tex. and may use, but is not limited to, a Linux based operating system.
