Description

 "Method of configuring a display monitor for a camera system, display monitor and camera system"

TECHNICAL FIELD OF THE INVENTION

The present invention relates to a method of configuring a display monitor for a camera system. It also relates to a display monitor and a camera system implementing such a method.

STATE OF THE ART

In the state of the art, there are known camera systems composed of at least one camera served by an operator or cameraman, sound recording means and lighting means.

 The film crew in addition to the operator includes several agents including the director of shots, the sound engineer, the script-girl, the lighting designer, the director of photography. Some stations are even doubled depending on the complexity of shooting, for example in systems with multiple cameras.

 Some or all of the filming agents are equipped with display monitors like the CineMonitor HD Evolution (Trademark) monitors from Transvidéo. Each monitor is connected by a communication channel to one or other of the cameras of the camera system so as to inform the agent who is wearing the display monitor of the view being recorded.

 This knowledge allows everyone to act immediately according to his responsibility in the shooting and avoids a great loss of time that is known during the traditional shootings during which it is necessary to interrupt shooting between two shots to examine the taken, and then decide if the last shot is correct and conserved or if it is faulty and requires to shoot again the same shot by correcting a data such as lighting, sound level, diaphragm or a setting. point.

In Figure 1, there is shown by way of example a shooting system for digital cinema in stereo. It has two identical digital cameras, ie a right camera 4 and a left camera 5 carried by a stereoscopic base ensuring correct deviation and orientation of the optical axes of the two cameras.

 Such a base, known in the art of shooting as a "Rig", may consist of an optical box with a semi-reflective mirror and two faces each carrying one of the cameras 4 or left 5. base has not been shown in Figure 1 for the sake of simplification.

 Each camera 4 or 5 comprises a digital camera 6 on which is mounted an instrumented optics 7. The digital camera 6 produces a video signal which is packaged in a video communication circuit 8 and the instrumented optics 7 produces a measurement signal of various optical state sensors which is conditioned by a digital data communication circuit 9.

 In the systems of shooting, it is known to use a standard of images HD to condition the video signal and the standard

RS232 to condition the measurement signal.

 The video signal conventionally comprises frame and synchronization data or image data, while the measurement signal contains the digital state data of the sensors of the instrumented optics 7 such as zoom, focal length and aperture, or others, together forming the measurement signals of shots.

 The communication circuits 8 and 9 are connected to a communication channel 10 for the right camera 4. The left camera 5 being functionally identical to the right camera 4, it has not been detailed in the drawing but is connected. likewise to its own communication channel 11 for the left camera 5.

 The two camera communication channels are associated in a global communication channel 12. The global communication channel 12 groups together all the video and measurement communication channels for all the cameras of the camera system. It is under the control of a communication controller (not shown) especially when the camera system has several display monitors.

The number of two camera communication channels, characteristic of a stereographic camera system, can be reduced to one if the system has only one camera or more than two camera communication channels if the camera has more than two cameras or cameras.

 Similarly, the global communication channel 12 comprises other communication channels not shown in FIG. 1, notably comprising:

 - audio data communication channels issued or generated by sound recording devices;

 - digital data communication data from or generated from lighting devices and / or lighting sensors;

 - State data communication data of ancillary shooting devices such as the Tally Light of each camera or camera and which comprises at least one warning light device indicating the shooting status of each camera of the camera system.

 The global communication channel 12 may take the form of a wired network or preferably a radio frequency network. The transmitters and receivers at the ends of the channel 12 are adapted accordingly as well as the communication protocols.

 The Display Monitor 3 which can be a CineMonitor HD Evolution

(Trademark) of the company Transvideo, includes a high definition display screen 19 with high definition digital video image generation circuits. A description of the monitor is available from Transvidéo and has been posted on the Web at:

 http: //www.zgc.eom/t/pdfs/lnstructions/Transvideo_CineHD_Operator -Manual_evol_1.1.pdf

which can be referred to for further details.

 Note the presence of a power supply display monitor rechargeable batteries. The display monitor being on battery is also portable.

 The global communication channel 12 is connected on the display monitor 2 to reception means which mainly cooperate with:

- a set of specialized resources to perform the display and management of graphic objects and the available image on the channel of global communication 12, the set of resources being implemented in a specialized integrated circuit 14 of the FPGA type;

 a microprocessor 15 capable of executing one or more management programs of the display screen 19 by calling, depending on the management program executed, the resources of the specialized integrated circuit 14 necessary for the video and measurement data present on the channel global communication system 12, a receiver (not shown) of which is integrated with the microprocessor 15 and the control data generated by the user on a user interface 17 disposed on the display monitor 3; and

 a memory 16 of data useful for the operation of the monitor as a function of the execution of the program or programs executed on the microprocessor 15.

 The user interface of the CineMonitor HD Evolution (Trademark) of the company Transvidéo is composed of a plurality of push buttons distributed along at least one edge of the display screen and a rotary knob 18 and allowing long or short presses, which serves in particular to enter variable values or to select one or more items from a list of articles displayed on the display screen according to the execution of the program on the microprocessor 15 .

 On the display screen 19, it is provided by means of one of the programs executed on the microprocessor 15 to generate or not one or more lateral zones in the direction of the height 20 or in the direction of the length 21, the directions of the height and of the length being included relatively respectively at the small and the large side of the display screen 13.

 Each lateral zone may display one or more graphic objects generated by one of the programs executed by the microprocessor 15 by using at least one computing resource of the aforementioned FPGA-type specialized integrated circuit 14. Such a graphic object may be an icon of a working tool of the image displayed on the viewing screen. Such an icon 21 is then disposed at a position 22 in one of the lateral zones under the control of the microprocessor 15.

It is then assigned by the program executed one or more buttons of the user interface 17 so that the working tool symbolized by the icon 21 can be selected, activated or deactivated or configured by the user who interacts with him and the display screen using the user interface 17. It is understood that several icons and therefore several work tools are freely viewable and usable depending on the execution of the user. monitor control program running on the microprocessor 15.

 Such working tools are described in the aforementioned manual. These include, but are not limited to:

 A tool for working on the sound levels of sound recording devices connected to the camera system;

 A work tool for editing the "timecode" or time mark of the video frames of the video signal (s) from the video signal channels of the global communication channel;

 A working tool to edit the settings of the instrumented optics of the selected camera and if necessary assist in modifying the settings of the instrumented optics;

 A working tool to assist the operator and the director of actors in the determination of the areas of development;

 A work tool for generating various markers on the image comprising a cross movable over several areas of the image displayed on the display screen;

 A work tool comprising an artificial horizon associated with a camera or a set of cameras having a determined attitude measured using a tilt sensor generating a displayed artificial horizon.

When a working tool has been executed on the user's control on the user interface 17, it is displayed on the display screen 19. The display operation of the work tool, executed by a user associated management program, is executed on the microprocessor 15 which calls one or more resources of the specialized integrated circuit FPGA 14. The associated management program then assigns one or more buttons of the user interface 17, such as the button 18, to one or more several commands so as to enable the user to provide control data or working parameters of the work tool such as his position on the display screen 19 or a numerical or other value which is then interpreted by the user. management program associated with the working tool running on the microprocessor 15. The specialized FPGA type integrated circuit 14 has been described in more detail in FIG. 2. Each resource 25-1 to 25-14 is called by a program routine executed by the microprocessor 15 on the internal bus of the monitor control circuits. display 3 (Figure 1). They can optionally be called by another connected electronic module (Ext) on the internal bus. Among the resources thus collected in the specialized integrated circuit 14 of the FPGA type are:

 a histogram generator on specific characteristics of the video signal received on the global communication channel 12 (Figure 1) and selected on the user interface 17 (Figure 1), such as color, luminance, etc. :

 a global communication channel monitor 12 (FIG. 1) as a radio frequency link;

 a waveform generator to be displayed on the screen 19 (FIG. 1);

 - a detector of "timecodes", or time marks on the shooting in progress;

 a focus sensor on the selected measurement signal of the integrated optics of the camera and received on the global communication channel 12 (Figure 1) and selected on the user interface 17 (Figure 1);

 - a color temperature meter;

 a plotter of curves for displaying measurement graphs on the screen 19 (FIG. 1);

 a marker generator on the screen 19 (FIG. 1) comprising lines, crosses, rectangles, and others;

 a frame generator on the screen 19 (FIG. 1);

 a colorimetric data meter on a selected region of the image displayed on the screen 19 (FIG. 1) and generated on the basis of the video signal received on the global communication channel 12 (FIG. 1) and selected on the interface user 17 (Figure 1) including the selection of an area marked by the marker generator or the frame generator;

an artificial horizon display for displaying an artificial horizon on the basis of a measurement signal transmitted on the global communication channel 12 (FIG. 1); an audiometric data generator performing the visualization of the measurement of the sound levels for each audio channel of at least one audio signal received on the global communication channel 12 (Figure 1) and selected on the user interface 17 (Figure 1) in from sound pickup devices connected to the global communication channel 12; etc.

 In FIG. 3, there is shown a work tool generated by a determined routine of a work tool management program executed on the microprocessor 15 (FIG. 1) using specific resources of the specialized integrated circuit. FPGA type (Figures 1 and 2) on the screen 19 of the display monitor 3 (Figure 1).

 To this end, the user must select a menu on a sidebar 20 or 21 to display the icon of the integrated optics work tool. For this purpose, the user must use the navigation button 18 of the user interface 17 to scroll through the menu items and choose the working tools corresponding to the menu item that has been selected. For this purpose, the management program executed on the microprocessor 15 monitors the presses on the button 18 to determine the item chosen in the menu.

 The menu monitoring routine then starts executing the work tool icon display routine corresponding to the menu item that has been selected. An icon of the integrated optics work tool such as icon 23 is displayed.

 When the user selects the icon 23 of the integrated optics work tool and activates it by clicking with the navigation button 18, the corresponding display routine of the integrated optics work tool represented in FIG. 3 is then displayed in a determined region of the screen 19 (FIG. 1).

 The integrated optics work tool shown in Figure 3 includes:

 a first graduated scale, marked with the drawing FOCUS, and which represents the focal length of the instrumented optics whose measurement signal is currently selected on the given camera;

a second graduated scale, marked with the IRIS drawing, which represents the opening of the objective of the instrumented optics whose measurement signal is currently selected on the given camera; a third graduated scale, marked ZOOM, which represents the magnification of the teleobjective of the instrumented optics whose measurement signal is currently selected on the given camera.

 Finally, the working tool of the integrated optics shown in Figure 3 has on the first scale FOCUS graduated a colored segment, disposed between the focal lengths of 63 meters and 97 meters, which indicates the depth of field. In addition, a vertical marker, generated using the appropriate resource of the circuit 14, makes it possible to display the focus by transferring to the depth-of-field segment the focusing of the telephoto lens measured on the third scale ZOOM at the zoom value of 36 mm.

 Such a tool allows some film crew members to make shooting decisions.

 There are thus about forty different work tools that use the resources of the circuit 14 and which are displayed at the request of the user of the display monitor 3 on his screen 19, when he is correctly connected to the communication channel. overall 12.

 A work tool thus includes data and programs executable on the processor 15 of the display monitor 2. This work tool is stored in the memory 16 and is executed when selected by the user on the interface user 17.

 For this purpose, it is called by selection on the user interface 17 with an icon and / or a special menu as it is known. It is then executed by the microprocessor 15 and, as the case may be user commands on the user interface 17, the executed work tool processes data available on the global communication channel 12.

 In response, the executed work tool displays representations of these processes on the data of the global communication channel 12, including the image data and the measurement signals described above.

 The display of these processing representations exploits graphical and other components called and generated on the special circuit FPGA 14 described above.

But, in the experiment, it appeared that, for a given user, the fact of being confronted, thanks to the various menus displayed on the screen, to all the work tools are too complex. The handling of the display monitor must be complete. However, an agent on a film crew such as a script girl or a cameraman does not need to know and use all the work tools available on each display monitor.

 All users of a display monitor connected to a camera system do not have the technical skills to configure and use each of the tools programmed on a display monitor intended to connect to a global communication network. 'a system of shots.

 It has therefore appeared a need to reduce the difficulty of using a display monitor with all available working tools.

 The present invention provides a remedy for this drawback of the state of the art.

The details of FIGS. 1 to 3 have already been described in the state of the art.

 In Figure 4, there is shown a block diagram of an arrangement of a camera system of the type described in Figures 1 to 3 and to implement the configuration method of the invention .

 In one embodiment, the camera system or at least one of its display monitors, cooperates with a computer 38 having an Internet browser 36, with a connection to the web network to execute a web client. or the Internet.

 In one embodiment, the computer 38 is available to a user of the display monitor for a camera system, while the remote configuration station 35 is available to the display monitor manufacturer. .

The Internet server 34 provides, on a given Internet site, an Internet page for example in HTML, including a html form. The user on the computer 38 connects using his browser on the Internet page proposing the downloading of files from configuration. Having opened this page in his browser 36, the user sees the display of the html form generated by the server 34. The form thus contains a list of identification files or configuration scripts of the display monitor 2 and a form submission button whose click, as it is known, triggers the issuing of an html request containing the request of the file selected by the user. Preferably, the file identification list or configuration scripts of the display monitor 2 is composed of indications of the business of the user. The user then recognizes his trade in the list of indications displayed in the request form. Each indication of the list thus points to a configuration file or script which has been previously programmed so as to determine a suitable subset of working tools for the display monitor as will be explained.

 The user who has a display monitor such as the display monitor 2 of Figure 1, chooses the display monitor configuration file 2 according to the trade he wants to exercise with the display monitor. 2.

 F-stop 'open' coding for the integrated optics associated with the selected camera on the display monitor.

 Other trades than those presented above are planned. Each of them is characterized by a predetermined choice of work tools and configuration of each work tool depending on the job.

 Each job thus corresponds to a script or configuration file of the work tools that is generated by a script generator or configuration file operated at the server 35 of configuration files.

 In an initial step of the method of the invention, a script or configuration file is written in the form of data and / or programs that are intended to be interpreted by the management program (s) executed on the microprocessor 15 of the monitor. display 2 which is the target of the given configuration file. When it is edited, it is verified that the calls of the resources of the dedicated circuit 14 of the target display monitor 2 do not cause conflicts.

This initial editing step is performed outside of a particular shooting system. It is executed on behalf of a set of potential users. The edited script or configuration file contains data and / or programs that allow programs originally installed in the display monitors to display only the tools corresponding to a specific trade to which a configuration file 'View' is dedicated.

 Once one or more configuration files thus edited, once this or these files loaded on a target display monitor 2, as will be described later, the management program of the display monitor 2 present to the user who has just turned it on two modes of operation: a) a mode called 'View' in which the user will select from a menu or list displayed on the screen of the display monitor 2 connected to a global communication network of the camera system with which it is associated, and b) a complete mode of use of the tools of the monitor in which the user can select and configure himself any available tool in the form of programs and recorded data. in the display monitor memory 2.

 When the 'View' mode which makes it possible to select a particular trade is activated when opening a session on a given display monitor 2, and when the configuration file is interpreted by the management program executed on the microprocessor 15, only the working tools corresponding to the business selected in the 'View' mode can then be used on the display monitor 2 on which the configuration file has been implemented.

 We will now describe a step of the configuration method of the invention during which a user will load new views 'View' corresponding to one or more identified trades. In this step, the user can have his display monitor for use in a particular camera system. But, the display monitor on which an additional configuration file will be loaded does not need to be connected yet.

Referring to Figure 4, once the query generated (a) by the user on the browser 36 and transmitted (b) from the html form filled by the browser user on a computer 38, serving as a navigation client on the Internet, the request is decoded by the actual server 34, which is programmed as an html page server with an html query interpreter. The decoding of the received form is then performed (d) on a job selection circuit 33. The job selected by the job selection circuit 33 is then used to find (d) in a database 31 of the configuration files the configuration file corresponding to the selected job. The server 34 receives from the base 31 the selected configuration file and downloads it (f) to the client computer 38.

 The configuration file is then stored in a memory 37 of the computer 38 of the future user. It is then discharged by any suitable means into a configuration file memory 39 of the display monitor 2. The latter is then ready for use and it will naturally be configured to its first power up.

 For this purpose, the program executed at the start of the display monitor checks for the presence of a configuration file 39. If there is no configuration file, the display monitor 2 continues its operation as per the state of the technique explained above with the help of Figures 1 to 3. If there is a configuration file in the memory 39, the startup program interprets the configuration data file 39 and makes available only the working tools prepared for the trade selected in step (a) above.

 The unloading operation (g) on the display monitor 2 of the configuration file downloaded to the computer 38 can be realized:

 By connecting the memory 39 of the display monitor to a port

USB of the display monitor connected by a suitable cable to the USB port of the computer 38;

 By connecting to a USB port of the display of a USB stick initially connected to a USB port of the computer 38 so as to receive a copy of the downloaded configuration file, or

 By connecting to an SD memory card reader of the display monitor of an SD memory card initially connected to an SD card recorder of the computer 38 so as to receive a copy of the downloaded configuration file.

 As a result, the user has a display monitor adapted to the needs of his trade, which greatly facilitates its use because the user has the only subset of work tools that correspond to its constraints or profession.

In addition, the configuration method has a number of advantages that make it possible to vary the applications of the display monitor. In an embodiment shown in FIG. 5, there is provided a step of identifying the target display monitor 2 when it is connected by a communication port 42, for example of the USB type, to the USB port 43 of the computer 38. described in Figure 4.

 Such identification can be performed by reading an identifier code stored in a memory 44 of the display monitor and this reading is performed during a dialogue between the server 35 and the computer 38 on which the display monitor 2 has been connected by an electronic connection such as a USB or RS232 serial link.

 In FIG. 5, the display monitor 2 shows its microprocessor 15 with a management program 40 running and connected to the memory 39 containing in particular the configuration file described above.

 The computer 38 is represented with its Internet browser 36 open on the Internet server 34 of the remote configuration station 35. With the aid of an application loaded into the html page accessed by the client station or computer 38, the identifier code 44 of the display monitor 2 is read by the Internet server 34 on the remote configuration station 35.

 It is thus possible, at the remote configuration station 35, to know the identifier of the display monitor and ensure a supply of configuration files in relation to the identifier.

 Similarly, it is also provided, or in its place, a step of identifying the user who must then, in the request form on the browser 36, enter an identifier, completed if necessary with a password . Once the identifications verified, it is intended in one embodiment to perform a sale step of the provision of provision of a configuration file under specified conditions of use.

 Such billing can be used either for the simple provision of the working tools of the configuration file, but also for making available by sale or rental of the display monitor itself.

Delivery of the configuration file is then decided after the billing operation according to procedures known to those skilled in the art. In another embodiment, shown in Figure 6, there is also provided a step of tracking the uses of the various work tools and / or resources of the special integrated circuit 14 and / or graphics components.

 In an exemplary embodiment, means 47 for recording the uses of the various working tools and / or resources of the special integrated circuit 14 and / or graphic components are provided, preferably on each display monitor.

 Similarly, the means 47 for recording the uses of the working tools also record an identifier of each user. It is thus possible to impersonally identify the user by saving the name of the configuration file currently stored in memory 39.

 In another embodiment, the configuration file when it is downloaded from the Internet server 34 (see FIG. 4) receives an identifier that makes it possible to establish a relationship between the configuration file stored in the memory 39 and the user who has produces the download request for this configuration file.

 To monitor the use of the display monitor work tools, when the management program 40 executed on the microprocessor 15 executes a call of a resource of the special integrated circuit FPGA 14, or a work tool, this call activates a counter, associated with this resource or work tool and implemented on the microprocessor 15 in the tracking process 47, so that over an accumulated period, the counter represents the number of calls of the resource thereby indicating the calls. the most importants.

 It is expected to record combinations of resource calls or otherwise, calling a work tool from the set of work tools defined by the configuration file so that resources, resource combinations, and / or most useful or less useful work tools are detected at a given display monitor, for a given user and for a given period.

This knowledge is useful for adapting the delivery of a configuration file to a specific user. But it can be associated with several users of the same monitor and / or multiple monitors by compiling usage statistics. To this end, it is planned to connect at least each display monitor. The connection resumes the link by USB ports 42 and 43, between each display monitor of the statistics and the computers 38 of their users. Each user can identify himself personally by an identification process 48 on the request form of a configuration file or by another procedure such as the registration of an identifier of the previously downloaded configuration file and the date of its download. .

 When each user computer 38 connects to a suitable html page produced by the Internet server 34 on the remote configuration station 35, the tracking data produced by the process 47 of the microprocessor 15 on the display monitor 2.

 The data thus recorded during the period of use since the last connection of the display monitor 2 and the computer 38 of the user to the configuration station are loaded by the Internet link of the computer 38 on the server Internet 34. The loaded data of the memory 39 are then provided to a calculating circuit 49 statistics of use of one or more display monitors and where appropriate one or more users.

 In the remote configuration station 35, the statistics calculation circuit 49 is connected to a utilization statistics consolidation circuit 50 according to the identification of one or more display monitors and one or more users to derive default configuration values to use a configuration file editor 30 when editing (h) a configuration file for a set of constraints or occupation determined.

 The step of tracking the uses of the various working tools and / or the resources of the special integrated circuit 14 and / or the graphic components is then followed by a step of calculating usage statistics of one or more monitors. display and where appropriate of one or more users. It is thus possible to determine the frequency of use of each tool, and to determine the most frequent or less frequent settings or any other criteria of use of the display monitors.

In one embodiment, the means for recording the uses of the various work tools and / or resources of the special integrated circuit 14 and / or graphic components are connected to the less per periods to a circuit for calculating usage statistics of one or more display monitors and, where appropriate, of one or more users. Preferably, such a circuit is implemented on the side of the server 35 which allows the editing and selection of configuration files.

 Finally, after the step of statistical calculations, a step of consolidation of the usage statistics is provided according to the identification of one or more display monitors and one or more users to derive configuration values from them. defect to be used in the editing (h) of a configuration file for a set of constraints or a specific trade.

 In an exemplary embodiment, the statistical calculation circuit is connected to a usage statistics consolidation means according to the identification of one or more display monitors and one or more users. Using the consolidated statistical data, we deduce default configuration values to be used in the h edition of a configuration file for a set of constraints or specific business.

 The generation of a configuration file and its selection have been described by the indication of a job of the user of the display monitor. It is understood that the indication of a trade may be replaced by any arbitrary or determined selection of one or more constraints leading to the selection of a subset of work tools on the display monitor.

 In Figure 7, there is shown in schematic form another application of the invention which illustrates several aspects.

 The camera system mainly comprises a camera 52 optionally equipped with sound recording means and cooperates with lighting devices. Several display monitors 51, 53 are also arranged and each used by a specialist in shooting.

Cameras 52 with lighting and sound pickup devices and others are connected through the overall communication channel 54 in the form of a radio frequency channel. The shooting data, and the measurement signals as well as the metadata taken are inserted in communication units according to a determined communication protocol which is not the subject of the present invention. In particular, as has been explained with the aid of FIG. 4, the shooting data are made accessible on the global communication channel 54 analogous to the global communication channel 12 of FIG. 4.

 Each display monitor 51, 53 is provided with means for displaying and operating work tools as explained above.

 According to the invention, at least one of the display monitors, here the display monitor 51, is provided with a display screen 61 and a user interface 62 as well as all the display monitors 53 It is, like these, equipped with a processor, a special calculation circuit containing resources for displaying work tools and a memory already described with the aid of the preceding figures.

 In the embodiment of FIG. 7, the display monitor 51 is also equipped with a modem 56 connected to a WAN type communication network such as the Internet network 55 so as to connect to a server such as an Internet server. 50, which is configured as shown in Figures 4 to 6.

 The modem is also connected to an http stack and to an Internet browser 57 so that the display monitor 51 is provided with at least one specialized access resource for connection to the work tool server described herein. -above.

 As has been described on an associated computer 26 (FIG. 4), it is thus possible to make a requestor such as the requestor 36 (FIG. 4) to submit a request to download configuration files to an Internet server 50 or the like. , similar to the server 35 (Figure 4) described above.

 As a result, the camera system may not need to cooperate with a computer such as computer 36 described in Figure 4.

 The set of functions that has been described with the aid of these Figures 4-6 can be implemented directly on the display monitor 51 which, for him, no longer needs to cooperate with a download module described. for example at 37, 39 and 42 in Figure 4-6.

 It is possible, even during a shoot, during a stage

(A) (Figure 7) of the method of configuring the embodiment of the invention, to load any work tool available on the server 50 on the display monitor 51 according to the desires of the agent that uses it.

 Whether or not the display monitor 51 has its own Internet connection resource 55-57, in another embodiment also shown in FIG. 7, it is assumed that the display monitor 51 has a subset of working tools to cover several trades.

 In this other embodiment, it is advantageous if there is a global communication channel 54 to then distribute, during a step (B) (FIG. 7) independent of the above-mentioned step (A), a communication tool. determined work on the display monitor 51 storing the subset of work tools determined to download via the global communication channel 54 to at least one of the other display monitors 58, 59, ... from group 53 of slave display monitors.

 To achieve this objective, the display monitor 51, called the master monitor, is configured as a master station on a local network created using the global communication channel 54 (FIG. 7). Such a master station is at least capable of transmitting data packets transmitted according to a determined protocol on the channel 54.

 The master monitor 51 selects the network identifier, ie ID # i, from one of the slave display monitors 53. The slave display monitors 53 are configured as slave stations on the local network created with the master station 51 on the global communication channel 54.

 Such a slave station is at least capable of receiving data packets at its network ID ID # i issued by a master station.

 According to a determined communication protocol, the data of the configuration file corresponding to a working tool missing in the memory of the network identifier display monitor ID # i are inserted by a network connection resource (not shown) executed on the processor of the master monitor 51, in communication data packets 63 on the global communication channel 54, and decoded by the network identifier recipient display monitor ID # i among the slave monitors 53.

The network identifier slave monitor ID # i, provided with a network communication resource (not shown) executed on its processor, decodes and extracts the configuration file into communication data packets received on the global communication channel 54. The configuration file received, decoded and extracted is then implanted in the memory of the target slave monitor 53.

 A new tool distributed at the initiative of the master monitor 51 is then available on one of the slave monitors 53, here the slave network identifier monitor ID # i.

 Typically, this embodiment of the invention enables the technical director of a film set to ensure that an operator or agent of the camera system is well equipped with each work tool that is necessary for the filming system. performance of his mission on the set.

 It is no longer necessary to stop shooting because one of the filming agents does not have a display monitor equipped with the correct working tool, or because the agent is unable to configure this. work tool. It is sufficient for him to report to the technical director with a master display monitor as the monitor 51 (Figure 7) that he misses his tool. The latter selects it from the memory of its own monitor 51 and transmits it to it on the local network defined by the global communication channel 54 to its slave display monitor 58 or 59.

 It is understood that the same possibility of creating a local network between the display monitors of the camera system of the invention is open with another communication channel than the global communication channel 54.

 In particular, it is possible to deposit the necessary configuration file, associated with the missing work tool, on a removable memory medium such as a USB key on a first display monitor that has it. Then, in a second step, the user will connect this USB memory stick to a receiver port of the slave monitor 58 or 59 on which the tool or the tool set is missing. The receiving port of the target monitor 58 or 59 is similar to that described at port 42 in Figure 5.

In another embodiment of the invention, there exists in the memory as the memory 15 of a display monitor a batch of several configuration files, each corresponding to a trade, each of them corresponding to a particular trade shooting. Another categorization configuration files depending on the constraints that were used to edit them (see step (i) of the process (Figure 4)) is possible.

 But with such a display monitor, the user has a simple way to choose at any time the set of work tools best suited to the actual situation in which he is on a shoot. All he has to do is access a menu that records the batch of configuration files as a list of trades or other categories, each corresponding to a configuration file loaded into the display monitor's memory.

 By selecting an item from the menu, referring by an icon and / or an identifiable business name (or other category), the user can then execute the configuration file associated with the selected menu item and thus have the tools to work that this configuration file defines and see them arranged and running on the display monitor screen according to the configuration programmed in advance.

 To this end, it is expected during the download request, that instead of loading a single configuration file, the user accesses a request to download a menu of a lot of trades and a set of files of associated configuration in the memory of the display monitors.
