DETAILED DESCRIPTION
Embodiments of the present invention provide videoconferencing systems, videoconference clients, and videoconference servers that provide satellite images of videoconference client physical locations to the videoconference clients. The satellite photographic images for a physical location are preferably provided in the form of physical location video data representing a moving picture of the physical location shown at increasing magnification, and can be combined with graphical images, text, and the like to provide further information. The videoconference system preferably obtains the images, text, and the like from a satellite image provider. While embodiments of the present invention are described in terms of a client-server paradigm, other embodiments operate according to other paradigms such as peer-to-peer paradigms and the like.
FIG. 1 shows a videoconference system 100 comprising a videoconference server 102 and a plurality of videoconference clients 104A-N engaged in a videoconference. Also shown is a satellite image server 106. Preferably videoconference server 102, videoconference clients 104, and satellite image server 106 are connected by one or more networks 108 such as the Internet.
FIG. 2 shows a process 200 for videoconference system 100 according to a preferred embodiment of the present invention where videoconference clients 104 obtain the physical location video data of their physical locations. During the course of a videoconference, videoconference server 102 and videoconference clients 104 send and receive audiovisual data according to well-known techniques.
Each videoconference client 104 identifies a physical location, such as a street address, latitude and longitude, or the like, associated with the videoconference client 104 (step 202). For example, each videoconference client 104 prompts a user to enter the address, obtains the address automatically from a Lightweight Directory Access Protocol (LDAP) directory, or the like.
Each videoconference client then automatically obtains physical location video data for the physical location from satellite image server 106 (step 204). The physical location video data preferably comprises a plurality of satellite photographs of the physical location. The physical location video data preferably represents a moving picture of the respective physical location shown at increasing magnification.
The physical location video data optionally further comprises graphic images of the respective physical location. For example, the video can begin with views of the Earth from outer space, followed by a series of maps, followed by the satellite photographs, all shown at a steady rate of increasing magnification to convey an effect of approaching the physical location from above.
Satellite image server 106 can be part of videoconference server 102, and can even reside on the same physical device, but is preferably operated by a satellite image provider that provides an application programming interface (API) for videoconference server 102.
Videoconference clients 104 preferably obtain the physical location video data before the first videoconference, and store the physical location video data for use in each videoconference, as described in detail below. Alternatively, videoconference clients 104 obtain the physical location video data at the beginning of each videoconference.
Each videoconference client 104 sends the physical location video data to videoconference server 102 (step 206), which receives the physical location video data (step 208) and then sends the physical location video data to one or more others of videoconference clients 104 (step 210). Preferably each videoconference client 104 compresses the physical location video data prior to transmission, and decompresses the video data on reception, according to conventional techniques. In some embodiments, videoconference server 102 stores the physical location video data, either compressed or not, for use in future videoconferences.
Videoconference clients 104 receive the physical location video data (step 212) and decompress the physical location video data, if necessary. Videoconference clients 104 then display the physical location video data (step 214). Preferably the physical location video data of the physical location of a videoconference client 104 is displayed automatically as that videoconference client 104 joins the current videoconference. In addition, a user can view the physical location video data at any time by manipulating a graphical user interface. Users can view the physical location video data for any videoconference client 104, including the user's videoconference client 104.
Preferably the physical location video data simply replaces the video portion of the regular videoconference audiovisual data, which continues to be received uninterrupted, but is not displayed. In other embodiments, the physical location video data is shown in a separate window concurrently with the video portion of the regular videoconference audiovisual data.
FIG. 3 shows a process 300 for videoconference system 100 according to a preferred embodiment of the present invention where videoconference server 102 obtains the physical location video data of the physical locations of videoconference clients 104. During the course of a videoconference, videoconference server 102 and videoconference clients 104 send and receive audiovisual data according to well-known techniques.
Each videoconference client 104 identifies a physical location, such as a street address, latitude and longitude, or the like, associated with the videoconference client 104 (step 302). For example, each videoconference client 104 prompts a user to enter the address, or obtains the address automatically from a Lightweight Directory Access Protocol (LDAP) directory or the like.
Each videoconference client 104 then automatically sends an indicator of the physical location to videoconference server 102 (step 304). The indicator can be the street address or some other indicator of the physical location.
Videoconference server 102 receives the indicator of the physical location of videoconference client 104 (step 306) and obtains physical location video data for the physical location (step 308), as described above with reference to FIG. 2.
Videoconference server 102 sends the physical location video data to other videoconference clients 104 in the videoconference (step 310). Preferably videoconference server 102 compresses the physical location video data prior to transmission, and videoconference clients 104 decompress the video data on reception, according to conventional techniques. In some embodiments, videoconference server 102 stores the physical location video data, either compressed or not, for use in future videoconferences.
Videoconference clients 104 receive the physical location video data (step 312) and decompress the physical location video data, if necessary. Videoconference clients 104 then display the physical location video data (step 314), as described above.
FIG. 4 shows a process 400 for videoconference system 100 according to a preferred embodiment of the present invention where each videoconference client 104 in a videoconference obtains the physical location video data of the physical locations of the other videoconference clients 104 in the videoconference. During the course of a videoconference, videoconference server 102 and videoconference clients 104 send and receive audiovisual data according to well-known techniques.
Each videoconference client 104 identifies a physical location, such as a street address, latitude and longitude, or the like, associated with the videoconference client 104 (step 402). For example, each videoconference client 104 prompts a user to enter the address, or obtains the address automatically from a Lightweight Directory Access Protocol (LDAP) directory or the like.
Each videoconference client 104 then automatically sends an indicator of the physical location to videoconference server 102 (step 404). The indicator can be the street address or some other indicator of the physical location.
Videoconference server 102 receives the indicators of the physical locations of videoconference clients 104 (step 406) and sends the indicators of the physical location of each videoconference client 104 in a videoconference to the other videoconference clients 104 in the videoconference (step 408).
Each videoconference client 104 in a videoconference receives the indicators of the physical locations of the other videoconference clients 104 in the videoconference (step 410), and obtains the corresponding physical location video data (step 412), as described above with reference to FIG. 2. Videoconference clients 104 then display the physical location video data (step 414), as described above.
