NEW HARDWARE ELEMENTS FOR THE DIGITON VIDEO TRACER:

---------------------------------------------------------------------------------------------------------------------------------------------

The DVC 304 Video Controller is the larger version of the DVC 301 Controller. It has 8 inputs and 16 outputs. Based on our operating experience the 8 outputs of DVC 301 Video Controller may be not enough in case of large events. The Control Cube engages 4 outputs and the remaining 4 outputs are not always sufficient. (For example if we operate more screens, we connect to video conferences, we transfer images to interpreters etc.) We have also expanded the service of the DVC 301 Video Controller. The DVC 304 cannot be only operated by USB, but we have also supplied it with a RJ45 network plug. The advantage of this service extension is that the system runner Control Cube can be removed from the DVC 304, so the USB port limited cable length is not problem. It can be controlled via local network or even the Internet. This also may be advantageous, because typically it connects to the Control Cube on the DVC 304 LAN placed on the technical location, so even the event moderator can manage the video control from the location with the help of the Control Cube graphical screen and a mouse.

--------------------------------------------------------------------------------------------------------------------------------------------

The PEP3010V Control Cube is the computer that controls the system. With its built-in special extension card, it is able to receive 4 HD-SDI signals. These four video signals may be recorded separately or with a single split image. The software of the Control Cube is the control software that manage the Video Tracer. It controls the DVC 301 and DVC 304 controllers, and the robot cameras via the Video Controllers. It prepares the event by programming the cameras, and setting the possible connections. The Control Cube is the controller of the event, where the pre-programmed video camera connections and the robot cameras can be controlled only by mouse clicks. The video of the event is recorded to the Control Cube winchester in Full HD quality. The floor sound sign gets beside the recorded video. The Control Cube sends the video of the event to the streaming server as a broadcaster. Our system is able to record video with split screen, and to stream video as well. The PC program of the Control Cube can connect to all known video streaming provider server. For the Digiton Video Tracer we operate a service website, where we can even provide events with large headcount. At this website, the video stream sent by the Control Cube can be also viewed in Full HD quality. The service ensures the lag-free, continuous, high-quality play with CDN technology. The broadcast can be public or private (protected by user name and password). The website is available at www.conferencestreaming.net.

---------------------------------------------------------------------------------------------------------------------------------------------

The PEP 3012V Video Conference Cube can connect remote participants to the event with image and sound. With the aid of special extension card it can connect to the DVC 301 or the DVC 304 Video Controllers. The video conference client program installed on the Video Conference Cube is able to connect even 200 remote participants' image and sound to the system. It is also possible that the remote participant's presentation appears on the screen of the event, so we can even connect a remote lecture to the event. The remote participant is enough to have a web camera and a microphone, as well as a free program installed on the PC, which has a simply used software. If we would like to connect two events (two Video Tracers) we also have to use the Video Conference Cube. The video conference service provides the low latency with cloud-based CDN technology. The low latency enables the PEP 3012V Video Conference Cube that with the help of Video Conference Cube we can ensure simultaneous translation with remote interpreters in the Digiton Video Tracer System. The remote interpreter can see and hear everything, what is happening on the event within 1 second delay. The video conference service can be tested on this website: www.conferencestreaming.net

 DVC 301 Video Center

 

 

 

 

The DVC 301 video controller operates as the video centre of the DIGITON Video Tracer system. It receives the video sources and switches them to the appropriate outputs. Any input may be switched to any output, and even one input may be selected for all the outputs. The number of the inputs and outputs are both 8. The DVC 301 controller is able to switch HD-SDI uncompressed audio-video sources even in the quality of Full HD 1080p 60 frame/sec. The DVC 301 controller unit sends the controlling signals to the DVC 100 robot video (speed dome) cameras. The HD SDI signal transmitted with the aid of a coax cable may be forwarded up to 120 m without refreshing. It connects via USB cable to the PC. The cameras must be connected to the standard RS-485 output.

 

          DVC 302 Adapter                    DVC 303 Adapter

A DVC 302 adapter is required for the monitors, projectors and the devices that ensure remote connection. It is practical to install the DVC 302 adapter near to the display unit in order to use coax cables on the longer distances. As required several display units may be also used in the system, for example the remote video conference connection may be allocated to a separate display.

A DVC 303 adapter is required for connecting HDMI audio-video sources. It is practical to place the adapter near to the HDMI device in order to forward the uncompressed video through a coax cable to the DVC 301 video centre. For the DVC 303 HDMI input we can connect for example a presentation notebook, media player, image from a remote location, namely the H323/SIP codec HDMI output.

 

 

 

 

 
 

The Control program:

The A DIGITION VIDEO TRACER is made by two different programs. One of them builds into the ICN 2005 ConferControl PC program. The other one can be used without conference sytem. The main difference between them is that in case of the ICN 2005, the stored postions of the robot cameras can be programmed to the delegate units. If the delegate unit’s microphone is active, then the camera focuses on the person, who uses the microphone. In the other program (without conference system) we can see an image of the room on the PC’s display and we can see buttons on the image.  We connected camera positions to the buttons in the preparatory part of the conference. During the conference the technician clicks on the button, which is connected to the person, who speaks and the robot camera automatically focuses on that person. The program ensures (with Multipoint Video Control Algorithm) that the system is able to serve out more cameras, more displays and more rooms with one operator and one video centre. Furthermore it ensures the Smart Recording video minutes, which means that only the relevant occurences are recorded in the video minutes. If someone speaks then his speech, if someone presents then his presentation, if someone plays video then the video, and if someone speaks from remote site then the remote site’s image can be recorded in the video minutes. The video’s voice is always equal to the floor sound. Of course the recording is FULL HD just like the system. Important to say that in contrast to IP based systems, the DIGITION VIDEO TRACER’s system has no delay on the displays. On the FULL HD screen the voice and the image is in lip-synch.

 

Some Typical screen of the software:

 

 

 

 

 

The image above shows a real scene. The small round buttons mark camera positions, which are ordered to chairs. The red button shows that participant, who is speaking. The oblong video source selector buttons can be seen on the top of the screen. Use these buttons to choose the displays and the recording sources.

During the preparation of the conference, we can program the robot cameras on the above screen. Here we can assign camera positions and video source for the buttons. We can recall this screen anytime during the conference, if we need some correction on the positions.

The video connection setting screen. We can connect inputs and outputs. We can specify all contact that occurs during the conference. (That is why it seems on the figure like we connected more inputs to one output). The settings on the above screen is an important part of the realization of the a Multipoint Video Control Algorithm.
