Description

The present invention relates to a Coding Drive (CODEC) driven touch screen video conference control system. In the prior art, a video conference system usually includes an encryption device (coder) and a decryption device (decoder), which are described as a coding decoder (CODEC), and compresses the video signal to an amount capable of being transmitted. In addition, it forms a function of decompressing (decompressing) up to a displayable amount. The output of the coding complex (CODEC) typically determines the appearance and feel of the display screen or monitor of the video conference system.

Known video conferencing systems generally fall into two categories. In the first category, control is performed using a dumb (non-intelligent) portable remote control device. Other video conferencing systems can also utilize touch screen intervention and display devices assisted by devices such as personal computers that are intelligent and can be programmed. In the former case, a dumb portable remote control device is used, and such a remote control device has a normal button, and when it is pressed, a command code or information in numerals or characters is transmitted to the CODEC by the infrared method. The Such a remote control device is not intelligent and can only perform a specified task by pressing a specific button.

In the latter prior art video conference system, the touch screen is used to control the video conference system. However, the touch screen is generally an accessory that is added later and the device itself is unique. Has a screen programming device and is not associated with a screen programming device supplied by the videoconferencing device manufacturer. Such a touch screen control system is operated by a program belonging to an intelligent device such as a personal computer. These touchscreen control systems have their own originality and design rather than those of videoconferencing system manufacturers. As a result, touch screen device programmers are virtually independent of screen control instruments because customers choose in any way and manner regardless of the appearance and feel of the video conferencing system on which the touch screen is operating. There is no consistency in or on the device. Furthermore, in such an installation method, the area of the touch screen corresponding to the function controlled by the manufacturer may be designed so that the prior art touch screen suppresses these control indications. Displayed on one of the monitors.

FIG. 1 is a schematic diagram of a touch control screen, designated generally by reference numeral 1 and manufactured for a prior art video conference system. In the type of system described in FIG. 2, the appearance and feel of the screen display of the videoconferencing system manufacturer is not captured or duplicated. Rather, the video conferencing system screen is essentially reprogrammed to perform functions according to the sequence and form of the touch control screen chosen by the individual programmer of the touch control screen. In the prior art system shown in FIG. 1, the control function is displayed on the screen or video conference monitor that the user sees, although the display may be suppressed as previously described. Furthermore, prior art operations require the cursor on the video conference screen to be moved to the proper location using the azimuth arrow 2, where the enter button 3 is pressed to control the resulting function. It is.
It is desirable to develop a control system for a video conference system that is compatible with the video conference system and that operates with the pre-programmed screen appearance and feel of the video conference system in order to increase compatibility and effectiveness. The present invention has been made with this in mind.

(5) As a further point, according to the teachings of the present invention, there is no need to use a cursor on the video conference monitor screen. In fact, using the present invention, there is no control function on the monitor screen of the video conference system.

  By using the coded composite (CODEC) -driven touch screen video conference control system of the present invention, a control function can be performed only on a remote control device without displaying a cursor for controlling the video conference on a video conference monitor. This is effective in improving the display on the monitor.

  First, FIG. 3 and FIG. 4 will be described. With particular reference to FIG. 3, a typical videoconferencing system known in the relevant art is generally indicated by reference numeral 10. The system 10 includes a camera 11 that provides a signal to a Coding Combiner (CODEC) 13 that sends audio-video signals to monitors 15 and 17. Coding decoder (CODEC) 13 can also receive signals from VCR 19, DVD player / recorder 21, document camera 23 and terminal personal computer 25. The VCR and DVD player / recorder are programmed to be displayed on the monitors 15 and 17 as can be seen from the double-headed arrows between the CODEC 13 and the video cassette recorder (VCR) and DVD player / recorder. The signal used and controlled to do can be sent from the CODEC to the VCR and DVD player / recorder. This VCR is used to record programming from the CODEC 13.

  Still referring to FIG. 3, the CODEC 13 has a port 27 from which the captured video can be obtained. Further, the CODEC has an auxiliary connection portion 29 from which API information can be obtained. “API” is an abbreviation for “Application Programming Interface”. This information transmission device accessed via the connection unit 29 allows the present invention to be connected to the CODEC 13 so that the present invention can supply the CODEC 13 with a desired series of commands and responses from the CODEC 13. It was.

Still referring to FIG. 3, the elements of the present invention are generally indicated by reference numeral 40 and include a touch screen remote control 41, a personal computer 43 and a video capture board 45. As can be seen, the personal computer 43 has a connection portion 47 to which a conductor 46 connected to the API information connection portion 29 of the CODEC 13 is connected. The video capture device 45 has a connection 49, which is connected to the capture video connection 27 of the CODEC 13 by a conductor 51.
The video capture device 45 under the control of the personal computer 43 supplies a signal to the touch screen 41 via the connection unit 42. When the user touches the screen 44 of the touch screen 41, the x and y position coordinates corresponding to the contact position are transmitted to the connection portion 57 on the personal computer 43 through the connection portion 53 and the conductor 55.

  As can be seen, the personal computer 43 is pre-programmed with data corresponding to the respective x and y position coordinates corresponding to the functions of the video conference system 10 related to the position of control of what functions on the touch screen 44. In other words, the touch screen 44 is supplied with patterns that are normally displayed on the monitors 15 and 17, which patterns correspond to various functions of the video conference system 10 as will be better explained with reference to FIG. Includes “buttons”. In accordance with the teachings of the present invention, these “buttons” are no longer displayed on the monitors 15 and 17, but are now displayed alone on the screen 44 of the touch screen 41.

Video signals are captured from the system 10 in the following manner (see FIG. 6):
S-video with monitors 15 and 17 outputs (including handheld remote control system supplied by the manufacturer) is sent from the CODEC 13 to the video capture device 45, which then understands the video as required by the PC / device program-one skilled in the art. Prunes and scales the video as it is placed in the “capture region” as defined by the program above.
Once the capture process is started, it is automatically advanced.

The touch screen transfer operation proceeds as follows (see FIG. 6).
The CODEC 13 dynamic link library (DLL) is designed to load a “Screen Behavior Definitions” file from the personal computer 43 when the user accesses it. This file lists all the guidance screens in the system and clarifies the XY coordinate information for each area on the screen.
When the user touches the “capture area” of the touch screen 44, the user interface module in the screen system 41 sends the coordinates of the contact to the personal computer for analysis.
The personal computer cross-checks the XY coordinates against the current screen and then performs the appropriate operation.
The personal computer always listens to a message informing that the screen is displayed.
The operation performed by contact is one of two general classes.
1) Command 2) The operation “command” is a raw CODEC API command. These are usually similar to “screen jump” or direct instructions to the CODEC 13.
“Operation” includes the use of a general purpose subroutine (some subroutines are possible) to determine what actually happens. Claims are specified in an action statement for optimal behavior. Generally, before the operation is complete, confirm the CODEC status or advance additional commands.
The display pattern is sent from the connection part 27 of the CODEC 13 to the video capturing device 45 and further sent to the touch screen 41 via the connection part 42. Thus, when the area on the screen 44 is touched by the user, the coordinates corresponding to the contact are transferred to the personal computer 43 via the conductor 55, and from there, the connection 47, the conductor 46 and Control of function changes on the monitors 15 and 17 is performed through the CODEC 13 in the same manner as the conductors 14 and 16 through the connection portion 29.

As described above, according to the teachings of the present invention, the need for a cursor on screens 15 and 17 is eliminated. Further, as in the prior art example illustrated in FIG. 2, it is not necessary to align the cursor with the area above one of screens 15 and 17 and press the “On” button. The areas on the screens 15 and 17 no longer exist, and only the screen 44 of the touch screen 41 has areas having functions of the system 10 represented by those areas.

  In accordance with the teachings of the present invention, the screen 44 includes two general ranges. That is, the central square portion that displays the accurate output of the CODEC 13 and the control for the active attached audio video apparatus such as the camera 11, the VCR 19, the DVD 21, the document camera 23, and the terminal personal computer 25 as well as the adjustment instruction for the CODEC 13. It is the edge of the four corners containing the button. In addition, an area on the screen 44 is sent a prompt display of information about the status of the system. Connections 42 and 53 are provided to couple the touch screen 41 to the subsystem and conference system linked to the present invention.

  Compared to the prior art, according to the teachings of the present invention, the system of the present invention captures the exact video output of the CODEC 13 and also duplicates the output of the manufacturer's portable remote device into the CODEC 13. In this way, the operation is always exactly the same as that designed by the manufacturer of CODEC 13. Each implementation of the system 10 is a prior art device, i.e., a touch screen remote control that is not based on a CODEC program, but rather a prior art device that is based on a remote control program, There is no contradiction even when compared.

FIG. 4 is similar to FIG. 3, but is condensed into the components of the invention described above. The numerical display in FIG. 4 is similar to the components in FIG. The system 40 of the present invention enables control of the functions of the CODEC 13 through the use of a simple-use touch screen 44 controlled by a personal computer 43 and an intelligent device that ensures logical operation, and makes the right choice for the user. This gives a second opportunity to make a request to prove that the operation has been performed by displaying, and prevents an erroneous operation.
More specifically, the personal computer 43 can execute logical instructions described in a computer program language. The personal computer 43 controls the operation of the video conference system 10 together with the video capturing device 45 via the PCI or other appropriate bus incorporated in the personal computer 43. The coupling of the CODEC 13 via the RS232 series is schematically shown in FIG. The transmission is instructed while exchanging between the connection part 47 of the personal computer and the connection part 29 of the CODEC. As you can see, these transmissions are compatible with the CODEC 13 manufacturer's application program information transfer device (API).

  Transmission also occurs through the use of a touch screen through a continuous transmission chain as shown in FIG. 4 and designated by the conductor indicated by reference numeral 55 and the connection of 53,57. As mentioned above, there is no cursor display on the monitor screen using the present invention. Rather, the touch screen 41 acts like a mouse, and when an area on the screen 44 (FIG. 3) is touched, the x and y coordinates of the contact position are transferred to the personal computer 43 via the conductor 55. Since the personal computer 43 is programmed in advance, an appropriate control signal is sent to the CODEC 13 via the conductor 46. If necessary, when the area on the touch screen is touched, the personal computer 43 may display a request to the user to contact the screen again to confirm the operation.

In summary, the personal computer 43 executes a special set of computer programming that initiates and controls all operations of the video conference system 10. The logic includes the following set:
(1) All operations of the touch screen 41 including all transmissions to and from the user;
(2) all operations on the video capture board; and (3) all requests to the CODEC 13 and all messages from the CODEC 13.
If necessary, the PC software may have a special password and security control to prevent tampering. An important key of the present invention is the fact that the personal computer 43 controls the video conference system 10 through the CODEC API of the video conference system itself through the CODEC API.

According to FIG. 5, all transmissions between the personal computer 43 and the CODEC 13 are performed in the same procedure. According to FIG. 5, when the user touches the screen 44, the user has accessed the system 40. Thereafter, the video capture board 45 captures video from the CODEC 13.
Next, the video capture board 45 sends the video from the CODEC 13 to the touch screen 44 via the connection part 27, the conductor 51, and the connection parts 49 and 42 on the touch screen system 41.
As pre-programmed by the personal computer 43, once the CODEC video is received by the touch screen system 41, the system 41 detects that the screen 44 corresponds to each area of the screen 44 where the function starts by touching that area. Overlay by y coordinate.
Thereafter, when the user wants to start a function, the user touches the touch screen in the area indicating the required function. In response to the contact, the touch screen system 41 transfers the x and y coordinates of the touched portion to the personal computer 43 via the connection portion 53, the conductor 55, and the connection portion 57 (see FIG. 3). The search table pre-programmed in the storage device of the personal computer 43 correlates with the x and y coordinates received by the personal computer along with the necessary operations. In response to this, the personal computer 43 transmits the API code to the CODEC 13 via the connection unit 47, the conductor 46 and the connection unit 29. The CODEC 13 resonates with the personal computer 43 via the same transmission path indicating reception of transmissions, and then the CODEC 13 performs the necessary operations via one of its connections and its associated conductor.

Next, the CODEC 13 sends an operation completion signal to the personal computer 43 via the connection unit 29, the conductor 46 and the connection unit 47. When the operation is completed as described above, the personal computer 43 waits for the next contact with the screen 44 by the user.
In order to understand the importance of the present invention, it is useful to contrast its operation with a prior art manufacturer-supplied portable controller. The present invention essentially overlaps the operation of a portable remote device from a CODEC manufacturer. In the version of the videoconferencing system manufacturer, a control screen showing a diagram indicating the necessary operations is displayed on the same device (TV screens 15, 17) that displays the videoconference.

A prior art portable remote device is shown in a video device (eg, a television screen) and presses the appropriate button on the portable remote device. An infrared signal is sent to the CODEC to indicate the position of the symbol in the picture of the imaging device and the desired operation. Since portable remote devices are dumb (non-intelligence: lack of logical intelligence), the logic of the sequence and operation must be determined by the user-for example, a logical check of "second opportunity" There is no possibility.
A CODEC remote device (similar to all virtual portable remote devices) is not easy to operate and intuitive. Often, prior art devices need to be operated by clicking and using a cursor on a monitor screen that is moved to the desired area by remote control. The operation of the present invention is described below.

  In the present invention, the control screen does not appear on the same video device (eg, television screen) that is used to project the video conference. Instead, the control screen video is “captured” by the video capture device (FIGS. 4, 45) and sent to the touch screen display (FIGS. 4, 44). The PC also performs another function. The personal computer transmits all information on the screen to the CODEC 13 so as to be displayed on the video devices 15 and 17 (for example, a television screen), and displays a video at a distant location in the video conference. This information screen originates from the personal computer 43 and hides distant images until they are erased by the user of the terminal via the touch screen. This is employed for safety (eg, do not loosen until authorized to display distant images).

  The CODEC 13 is an encryption / decryption device (coder / decoder) manufactured by several different manufacturers. It is the central part of the video conference system. With the exception of control, it essentially performs all intelligent operations of the video conference system. It determines what video sources (cameras, VCRs, DVDs, document cameras, personal computers) are displayed on the video device, establishes contact with the remote location and receives operational commands to perform the necessary operations (eg, Make a video call, display a list of contacts, display a VCR, etc.).

  In the present invention, it is described how the touch screen remote control invention works rather than how the CODEC 13 works. The contents of the CODEC screen and the functions performed by CODEC are not centrally related. What is related is how the personal computer 43 is connected to the CODEC 13, how the API command is executed, how the command is sent and received from the CODEC, and so on. What is special is that each was done separately, for example capturing CODEC video screens, covering them with x 'and y' coordinates, and sending control codes from touch screen 44 to personal computer 43 And sending a message from the personal computer 43 to the touch screen 44.

  The touch screen system 41 consists of an LCD screen or other video display technology (CRT, plasma, etc.) 44 (FIG. 3) that can be resized. In addition to the display screen, the touch screen includes hardware that covers the screen with x 'and y' coordinates. When the touch screen display is touched, a “mouse click” presenting the x ′ and y ′ coordinates of the screen range is transmitted to the personal computer 43. The personal computer 43 logic recognizes the location by means of a programmed search table, thereby activating the implied control code. The personal computer 43 transmits a code (compatible with the CODEC API protocol) to the CODEC 13 via the connection unit 47, the conductor 46, and the connection unit 29 (FIG. 4). The CODEC 13 then executes the requested command.

The periphery of the touch screen is delineated by all four corner rectangle commands and information. These rectangles are always in the same position and are always manipulated in a special way. The periphery of the screen is preferably composed of four command areas.
-Camera control (upper left corner)
-Video input (upper right corner)
-Voice control (lower left corner)
-Function (lower right corner)
It also has three operating state / help buttons.
-Off / On-Line-Help (When "Help" is pressed, the next button appears.
○ Support contact ○ User's manual ○ Three sets of software (SMCS module) information-Transfer (rapid transfer function)
If this system is subscribed to a transmission line roll call, an additional “Network Statistics” button is displayed. By pressing this button, the user can view several pages of network statistics directly from the CODEC 13.

In a given system (determined by system setup time), one or more cameras can be included. Camera control consists of six buttons.
Zoom in-Zoom out-Left point camera-Right point camera-Upper point camera-Lower point camera The button is pressed and kept pressed until the camera moves the requested area.

The video input consists of 5 buttons.
-Main camera-DVD
-VCR
-Document camera-External computer Activate the video source by pressing one of these buttons. If desired, it is displayed remotely on one of the video devices.

The video source button is used to request connection to the required video source. A typical video conference system displays two images.
○ Distant location ○ Near location or variable video source (DVD, VCR, document camera or PC)
In a single monitor (video device), one video is displayed on the main part of the device. The second video is displayed on the screen (PIP) in the screen. In a dual monitor system, the left monitor displays far and the right monitor displays near or variable information (DVD, VCR, document camera, external computer).

Voice control consists of four buttons.
-Volume down-Volume up-Mute / non-mute Voice-Mute / non-mute By holding down the microphone volume up or down button, you can raise or lower the sound until there is no more sound. The mute / non-mute button can be used to mute or turn off the microphone or speaker sound.
There are four function controls.
-In the information transfer mode, the mode is switched between the video conference mode and the introduction mode.
-Logout Place the system in idle mode.
-Open Admin ○ User setting (for security password maintenance)
○ Cleaning (purification of CODEC security detection information at the time of repair)
-Main / Back (returns the operation back)
Time and date are displayed on the screen.

Thus, the present invention has been disclosed in its embodiments and has achieved any of the objects of the invention described above. It provided a new and useful CODEC driven touch screen video conference control system.
Of course, various changes, modifications, and alterations will occur to those skilled in the art without departing from the scope of the present application.
Accordingly, the invention is not limited to only the language of the following claims.
