Chapter 2 Installation of IVC-4300 

2.1 Hardware Installation 

Follow the steps below to install IVC-4300. 

1. Power off the computer. 

2. Plug IVC-4300 into a PCI slot of your computer. 

3. Fasten IVC-4300 on the computer case. 

Note: IVC-4300 will take up or share several sets of IRQ and I/O Address. Make 

sure there are enough free sets of IRQ and I/O address for IVC-4300 to use. 

The IRQ of the PCI slot can be modified from the BIOS settings of the 

motherboard. Please refer to the motherboard’s user manual to make any 

necessary adjustments. 

2.2 General Purpose Input Output (GPIO) Connections 

The GPIO module contains a GPIO daughter board, an input connector and an 

output connector. The GPIO module allows users to connect four input devices 

and four output devices. Please refer to Figure 1.

Operation procedure 

1. The active state of DVR software configuration is Normal Open. 

2. Cm and NC should have signals before and after system is turned on. 

3. When an event occurs, Cm and NO will have signals. 

Alarm devices should be connected to Cm and NO connectors so that event action 

will be triggered only when an event happens and will not be affected when 

system restarts.

companion CD of IVC-4300. 


Chapter 3 IVC-4300 SDK Programmer Guide 

3.1 Introduction to DirectShow Application Programming 

A complete documentation about DirectShow application programming can be 

found on Microsoft website. If DirectX 9.0b or later SDK is installed, this 

documentation is also available from DirectX SDK Help. 

The main goal of writing a DirectShow Application is to build a filter graph by 

connecting several filters together to perform a given task such as previewing 

video or audio, capturing video or audio and multiplexing them to write into a file. 

Each filter performs a single operation and passes data from its output pin to the 

input pin of the next filter in the graph. 

To build a capture graph using a program, the first thing to do is to obtain the 

interface pointer of the capture filter. IVC-4300 Video Capture Filter can be 

obtained through system device enumerator. After holding an interface 

pointer to the capture filter object, use method 

IGraphBuilder::AddSourceFilter to add the source filter object to the filter 

graph. Use IFilterGraph::AddFilter to add other downstream filters to the 

filter graph. After filters are added, call IFilterGraph::ConnectDirect or 

IGraphBuilder::Connect methods to connect output pins from upstream filters 

to the input pins of the downstream filters. Calling methods 

IMediaControl::Run, IMediaControl::Pause or IMediaControl::Stop will 

change filter state to running, paused or stopped. 

The filters needed for capturing MPEG2 and MPEG4 streams are listed in Chapter 

3.2, with detailed information for each filter and its pins. Example filter graphs 

for previewing/capturing MPEG2 and MPEG4 streams are illustrated in Chapter 

3.3. Chapter 3.4 gives examples of two ways to control device driver. 

**Note that the MPEG2/1 decoder recommended is InterVideo video codec, which 

is not included in our SDK package. Please refer to InterVideo website 

http://www.intervideo.com/ for more information. 

3.2 Filter Description 

This chapter lists filters necessary to build a filter graph for capturing and/or 

previewing MPEG4/2/1 video and audio streams. 

3.2.1 Source Filter 

IVC-4300 Video Capture Filter belongs to the category of WDM Streaming 

Capture Devices. It is actually a kernel-mode KsProxy plug-in. An application 

can treat it simply as a filter. Use System Device Enumerator to add this filter to 

a filter graph.

3.3 Example Graphs 

Microsoft DirectX SDK provides a useful debugging utility called GraphEdit, which 

can be used to simulate graph building. From the Graph menu of the GraphEdit 

application, click Insert Filters and choose the desired filters. Filters are 

organized by categories. Click Insert Filter to add the filters to a graph. Then 

connect two filters’ pins by dragging the mouse from one filter’s output pin to 

another filter’s input pin. An arrow will be drawn if these two pins agree on the 

connection. 

After inserting IVC-4300 Video Capture Filter, right click the rectangle and click 

Filter Properties. The filter properties dialogue will appear. Set video and 

audio settings before connecting video pins or audio pin to other filters. The 

property screens are shown below: 

Video Setting: 


Audio Setting: 

Note: MS and IMA ADPCM sample bits are 4 bits, PCM only supports 16 bits. 

Video Decoder: 

If the device is a capture board, IVC-4300 Video Capture Filter will have an 

“Analog Video In” input pin. The CrossBar Filter needs to be inserted at this time 

to allow video source switching. Right click on the crossbar filter and click Filter 

Properties. The filter properties dialogue will appear, shown as below:

Appendix A FAQ 

1. What kind of compression solution is IVC-4300? What is the 

minimum hardware requirement for using IVC-4300? 

IVC-4300 is an MPEG-4 hardware video and audio encoding card. The 

dedicated hardware chip on the card performs only MPEG-4 encoding 

function, which needs to be performed by software via CPU resource. 

Usually, decoding 4 video channels with full D1 resolution (720 x 480) needs 

Pentium 4 3.0G or faster CPU to achieve real-time decoding performance. 

Decoding more channels needs faster CPU to achieve the same performance. 

2. Can IVC-4300 card driver be upgraded directly? 

No. To upgrade or re-install IVC-4300 device driver, or to add more 

IVC-4300 card into the system, always remove existing IVC-4300 device 

driver from control panel “Add/Remove Program” first. Restart the system 

to complete the uninstalling procedure. After then, you can install IVC-4300 

device driver. 

3. When using Windows device manager to remove single card, the 

system reboots automatically. How can this problem be solved? 

Do not disable or uninstall single IVC-4300 capture device by Windows device 

manager; otherwise the system will reboot automatically whenever you try to 

enable or install the driver again. This is an OS issue, and will be solved in 

Windows XP Service Pack 2, or later editions. 

4. Why IVC-4300 cannot work properly on some on-board VGA cards? 

How can this be solved? 

Display of video for four or more channels costs lots of system and display 

card resources that some on-board VGA cards cannot handle well. Below is 

a list of VGA card drivers verified by IEI. You can refer to the list for 

consideration of types of VGA card to use with IVC-4300. 

a. Windows 2000 + SP4 for an Intel 865G based VGA card: VGA driver 

version 6.14.10.3943, 6.14.10.3619 works fine. 

b. Windows XP + SP1 for an Intel 865G based VGA card: VGA driver 

version 6.14.10.3943, 6.14.10.3510 works fine. 

c. Windows XP + SP2 for an Intel 865G based VGA card: VGA driver 

version 6.14.10.3943 works fine. 

5. Why there are drop frames sometimes when DemoApp works? 

DemoApp of IVC-4300 uses Microsoft DirectShow filter for recording. If the 

load is heavy, it will drop frames sometimes when recording files on remote 

network drive. 

6. When multiple cards are inserted at the same time, can the same ID be 

assigned to them? 

No. A unique card ID has to be assigned to each card for IVC-4300 to 

identify which channels the device is mapped to. The card ID cannot 

duplicate; otherwise the capture device will not work properly. 

7. Can the default status of SDK be changed? What will happen if the 


status is changed? 

It is highly recommended to keep SDK status as default or the capture 

application may fail to find necessary codec or filter.
