Configuring a X-VIEW DPXe Wall Processor system is fairly easy, a typical system will comprise of a Master Wall Controller frame, an expansion frame (if the system requires more than 9 slots provided in the master frame), Display output modules and Input Modules, along with X-View Wall Control software and license key.

Step 1. Outputs

To begin, we first need to know how many display output will be required, this is determined by the number of display monitors used in the video wall design. The XV-IMG4DP is the display output module which provides 4 outputs per card and each card takes up 1 slot. Typically up to 10 cards can be installed in any one system which allows 40 displays.
2x2 video wall = 4 display monitors, this will require 1 card XV-IMG4DP and will use up 1 slot.
3x3 video wall = 9 display monitors, this will require 3 cards, since each card provides 4 outputs, with 3 cards we will have 12 outputs, out of which 9 will be used and others will be spares. This will take up 3 slots.

Step 2. Inputs

We next need to determine what type and number of inputs that are required, there are a variety of input options available for the X-VIEW DPXe therefore please refer to the current list of products to determine which one is most suitable.
16 composite video inputs, 2 computer inputs are required in this example, therefore this would use:
2 x XV-SD8 8 input CV per card = 16 CV inputs, 2 cards which would use up 2 slots
1 x XV-RGB-E2S 2 input DVI/VGA per card = 2 Computer inputs, 1 card which would use up 1 slot.

Step 3. Master Frame

There are 3 choices in terms of the master frame available, each one has different CPU processing power, for most applications the XV-VIS800 is suitable, if a high number of computer inputs or IP video stream decoders are required then either the XVVIS870 or XV-VIS890 should be selected. All models of master frames are available in either single ATX power supply or Dual Redundant Power supply options, generally we recommend the use of the redundant PSU frames. All video wall configurations will require at least 1 master frame, which will provide 9 slots.

Step 4. Expansion Frames

Each expansion frame provides a further 9 slots, typically up to 2 expansion frames can be installed with one XV-VIS800, if more expansion frames are required then the XV-VIS870 or XV-VIS890 controllers should be used as the master frame. The expansion frames interlink to the master frame via a short (0.75M) multi-core cable, therefore expansion frames will need to be installed either directly above or below the Master frame in the system rack. This cable cannot be extended beyond 0.75M due to signal losses and performance issues. This cable is used to extend the PCIe bus between frames, which uses high bandwidth data transfers and hence needs to be no longer than the supplied 0.75M length.
Add up the total number of output display cards and input cards required, this will then give us the number of slots required, if the number is less or equal to 9 then we can install all cards in one master frame, if it exceeds 9 then one or more expansion frames will be required. The expansion frames are available with single or redundant PSU options, in general we recommend use of the redundant PSU.

Step 5. Wall Control

All systems will require 1 x XV-Wall-CTL software application and license key, the wall control software is installed onto the master frame with a USB license key dongle. Wall Control application is required in order to create, save and recall custom layouts for the video wall. The Wall Control Client application can be installed onto other PC's which are connected on the same network as the Master frame to provide further remote control points. No additional licenses are required for this.

Step 6. Sequence and Scheduler

The XV-SEQ-SCH software application allows for scheduled and timed layout changes, the software is installed on the master frame, this application is mostly used for digital signage and mall display video wall systems where the display on the video wall may need to change at pre-set times.

The above steps are all that is generally required in order to configure an X-VIEW DPXe Video Wall system.

IP Video / CCTV System Configuration

This section deals with the system configuration when IP Video streams from CCTV cameras may need to be displayed with the X-VIEW DPXe Video Wall Controller. IP Video streams (RTSP) are decoded by the X-VIEW XV-RS870 1/2/3 Render stations, the render stations are available with 1, 2 or 3 Decoder processors fitted inside one 4RU frame. Each decoder CPU is associated with a dual head NVIDIA Graphics card which provides a mosaic DVI output of the chosen IP camera streams. The DVI output from the NVIDIA Graphics card in the Render station is then connected to a XV-RGB-E2S DVI input, using wall control application the mosaic input is then split into individual windows which can then be independently positioned and sized anywhere on the video wall display. Each processor in the XV-RS870 can decode 16 IP video streams and provides 2 DVI outputs where each output comprises of a mosaic of 8 videos. Each XV-RS870 can have a maximum of 3 processors, which allows for a maximum of 48 IP video streams per Render station (XV-RS870-3), a 3 processor system will provide 6 outputs which will require 3 x XV-RGB-E2S input cards in the X-View DPXe configuration. Multiple XV-RS870 Render stations can be used within a single X-VIEW DPXe video wall configuration, it is recommended to use the XV-VIS870 or XV-VIS890 master controller frames when decoding more than 16 IP video streams for optimal performance.
240 IP Video streams
240 divided by 16 = 15 Decoder CPU's, each XV-RS870 can house a maximum of 3 CPU decoders, 15 divide by 3 = 5 x XVRS870-3, with 6 outputs per XV-RS870-3 =30 DVI outputs in total.
30 DVI inputs divide by 2 = 15 x XV-RGB-E2S cards that would be required in system configuration.
Assuming we have a video wall of 16 display screens a typical X-View DPXe system configuration for decoding 240 IP Video streams would comprise of the following:
1 x XV-VIS890 Master Frame
4 x XV-IMG4DP 4 channel display output cards (Total 16 outputs)
15 x XV-RGB-E2S 2 Channel DVI input cards (Total 30 DVI inputs)
2 x XV-VIS800X 9 slot expansion frames (Total 18 slots + 9 in Master = 27 slots)
Out of the total 27 slots 19 are used by the input and output cards and 1 slot in the master frame is used by the expansion Link card, therefore 20 slots are taken which leaves 7 slots that can be used for any additional input or output cards in future)
5 x XV-RS870-3 Render Stations with 3 Decoder CPU's per frame
1 x XV-WALL-CTL Wall control application and license key
1 x XV-WCTL-IP IP Decoder License upgrade
