Definitions

  • the present invention relates in general to a system which allows a viewer to view a remote location, in real time.
  • Such systems are known in the implementation of a dedicated system, where one user is able to view one specific location through the use of one specific camera which is linked to a monitor at the viewer's location by means of a suitable information transfer system, for instance a conductive cable, optical cable, or a wireless communication system.
  • a suitable information transfer system for instance a conductive cable, optical cable, or a wireless communication system.
  • the viewer can only view the scene observed by the specific camera from one specific location, i.e. where the monitor is located.
  • a dedicated system needs to be set up for each combination of location to be watched (camera) and location where the viewer can watch (monitor) .
  • An object of the present invention is to provide a system which allows the images generated by a specific camera to be seen by any number of authorized viewers, independent from the location where those viewers are located. Further, the present invention aims to achieve this objective with a minimum of system costs.
  • the present invention aims to provide a system which is flexible in design, in that the locations which can be viewed as well as the persons who are authorized to view these locations can easily be amended.
  • a computer network preferably but not exclusively the Internet.
  • Connection between a user and camera is made through one specific Internet site.
  • a user who wants to view a specific scene enters the scene of his choice, his name, and his personal password or other suitable identification number.
  • the Internet site determines whether this specific user is authorized to view the scene of his request, and if so, the connection to a specific camera is made.
  • the connection is a one way connection allowing the user to view in real time specific scenes on his computer or other type of viewing apparatus, for instance a telephone with Internet facilities and suitable display. Normally, the connection is for images only, but the connection may be for sound, too.
  • the invention offers great flexibility in respect of the viewers. Any interested viewer needs only to have an Internet surfing apparatus, normally but not exclusively a personal computer. The interested viewer needs only to remember one address of one Internet site, independent of the location he wishes to see. The interested viewer needs only to contact this Internet site, and enter his demand.
  • the system may comprise cameras which are freely accessible to anyone, but normally access to a camera is restricted to a certain number of authorised persons; therefore, the interested viewer needs to enter his name and authorisation code. This information is also used for billing the viewer.
  • the invention also offers great flexibility in respect of the places which can be monitored. Whenever a new location joins the system, all that is needed for the company operating the system is to install a new camera with an Internet interface. Then, through the Internet, communication with this camera is possible from anywhere in the world, always through said one Internet site and under the exclusive control thereof.
  • a- computer network is generally indicated by the reference numeral 9.
  • This computer network 9 is for instance the Internet, although the applicability of the present invention is not limited to the Internet.
  • the Internet comprises many Internet sites, each having a unique address, which can be visited by simply typing the desired address in a suitable browser.
  • such site is implemented by a computer, which can send information through the Internet to a visiting computer.

  • the figures also show a user, generally indicated as visitor 1, with a web surfing device which, in the example shown, comprises a personal computer 2 including a monitor 3 and a keyboard 4.
  • a web surfing device which, in the example shown, comprises a personal computer 2 including a monitor 3 and a keyboard 4.
  • the present invention is not limited to the use of a PC as web surfing device; instead, the present invention is applicable in the context of any type of web surfing device, such as for instance a mobile telephone with web surfing facilities, a TV-set with a web surfing appliance, a personal digital assistant (PDA) , etc.
  • PDA personal digital assistant
  • the only condition is that the web surfing device comprises a monitor 3 or can at least be coupled to an associated monitor 3 for displaying images.
  • the system further comprises at least one, but preferably a large number of, remote stations 30, each remote station 30 comprising a remote camera 31 connected to the Internet 9 through an associated web connecting device or web interface 32, typically a computer.
  • This web interface 32 is designed to catch the image signals from the associated remote camera 31, and to send (41) these signals through the Internet 9 to the host site 10 in a suitable format. Since such web interfaces are known per se, a more detailed description thereof is not necessary here.
  • a person wants to subscribe to the visual connection services of said host site 10 he must first register with the company which operates the host site 10. An operator of this company will determine which cameras are accessible to this subscriber, and will issue an authorisation code to the subscriber. This information is also entered into an authorisation table in a memory 11 associated with the host site 10.
  • the visitor 1 wants to be connected to a specific remote camera 31 he visits (42) the host site 10, where he will be asked to input information regarding, on the one hand, the remote location 30 he wants to view and, on the other hand, regarding his identity and a password or other identification number.
  • the host computer 10 verifies the information as received in an authorisation table, to check whether this visitor is authorized to receive images from said specific remote camera 31.

  • the host site 10 may comprise a further memory 12, in which the host site 10 will store the identity of the last N cameras for each visitor, the number N for instance being equal to 10.
  • the host site may present the visitor a list of recent visits, and the visitor may re-visit a certain camera by clicking or doubleclicking on an item in the list. In case access to such camera depends on repairing, the host site will ask the visitor to enter his particulars .
  • An important advantage of the present invention is that visitors, whether they are authorized or not, can not access a remote camera 31 directly.
  • the web interface 32 associated with that camera 31 would not send image signals to such accidental visitor, because the web interface 32 is designed to send such signals to the host site 10 only, or to send such signals to specified computers only in response to instructions received from the host site 10.
  • a visitor 1 can only receive image information from a specific remote camera 31 if authorized by the host site 10. This authorisation will be given by the host site 10 only if certain conditions are met, depending on the circumstances.

  • one or more cameras 31 are installed to monitor a specific location associated with only one user, for instance his home, his office building, a parking place for his car, etc. From any location in the world, the user can check whether his house, office, car, etc., respectively, is alright, by connecting to the host site 10 and entering the desired destination and his password. Specifically, cameras may be installed in children's bedrooms; even if one is away from home, one may check whether the children are alright.
  • the user may receive his access code or authorisation code on installation of the camera.
  • An example of such situation is a school classroom, a daycare center, etc.
  • the parents may have to leave their children to the care of other people, such as a teacher, a daycare center attendant, etc., and although they normally have full confidence in the capabilities of such other people, parents feel the need to check upon their children themselves now and then.
  • Such facility is offered by the present invention, too.
  • a daycare center wishes to offer this facility to the parents, one or more cameras 31 are installed in such daycare center.
  • Parents receive an authorisation code upon registration of their child to such daycare center. If these parents feel the need to watch their children, they visit the host site 10 according to the present invention, enter their name and authorisation code, and the images of the daycare center in question are relayed to them. In such a situation, the authorisation of the parents may be restricted to the moments that their children are actually present in the daycare center.
  • Another typical example regards events which can only be visited by a limited number of people. Examples of such events are, for instance, sporting events, musical events, etc. If the tickets are sold out, a large number of potential visitors who would in principle be willing to pay for such visit must be disappointed if they can not visit. Also, potentially interested people may be unable to attend because they are living far away from such event, or for any other reason.
  • cameras may be installed at such events, and visitors from all over the world may watch such event in real time, on payment. Thus, not only do those visitors benefit, but also the organisers of such event may be able to make more money than by selling tickets to a limited number of visitors.

  • a certain product being manufactured on demand for a certain customer.
  • the authorisation code may be issued when the processing of the product is ordered; this information will also be used to connect the customer to the correct camera along the process line, i.e. the camera which momentarily corresponds to the specific product associated with this specific customer.
  • Another typical example regards the cameras which are installed near motorways in order to monitor the traffic.
  • these cameras are intended for traffic police, only.
  • the images are made available to the public, for instance to allow a driver, before leaving, to check upon the traffic intensity. It may be that the operator of the host site 10 decides to make these images available to everybody free of charge. However, it is also possible that the operator of the host site 10 decides that access is only open for subscribers at a certain fee.
  • cameras are installed for showing scenery to remote tourists, for touristical PR purposes .
  • Another typical example regards cameras which are employed on exploring vehicles such as satellites. It may be that the images provided by these cameras are for internal, scientific use only. The present invention, however, provides a way of making these images available to the public, possibly on a commercial basis.
  • the host site 10 will show a visitor all possible connections on one page.
  • the host site organises the connection possibilities into groups, for instance: “guarding premises”; “schools”; “daycare centers”; “events”; “processes”; “scenery”, etc.

  • the host site 10 only asks the visitor for an authorisation code if he has selected a camera with restricted access. However, it may also be possible that the visitor is asked to enter his authorisation code first, and that, in the above-indicated web-pages, options will only be presented to him if such options are accessible with his specific authorisation code (or without needing a code) . It may even be possible that the visitor is asked to enter his authorisation code first, and that the host site will understand that the authorisation code corresponds to only one camera and will make the connection automatically.
  • cameras 31 may be equipped with a memory 33 in which images (footage) can be recorded and kept for a predetermined time, preferably at least a number of days. If the host site receives a request from a visitor to view a recorded event, the host site will instruct the remote location 30 to send these recorded images over the network 9.
  • Billing for the facilities offered by the present invention may be done in several ways. For instance, it is possible that the user pays a fixed amount of contribution to the host site 10, for having the facility available, whether or not the facility is used at all. This type of billing scheme may be adequate in cases where there exists a one-to-one relationship between a visitor and a camera, for instance in the above-described example of cameras guarding the premises of a user. In other examples, the user may be billed for each image connection set up on his request through the host site 10, or for the amount of time such connection lasts. In both cases, billing may be combined with a fixed amount of subscription.
