 | Windows XP Service Pack 1 or later (Unless IPv6 multicasting is used, Windows 2000 SP3 or later). |
| DirectX 9.0 or later |
| Microsoft C runtime library: msvcr70.dll, msvcp70.dll |
| Borland C++Builder runtime library: borlndmm.dll, cc3250mt.dll |
| DirectShow-compatible codecs such as Microsoft MPEG4 codec V2 (when sending and receiving compressed data) |
| CPU: Pentium 4 1.8GHz or higher (recommended) |
| Memory: more than 512MB (recommended) |
Sender application (rsSenderUI.exe) requires video capture devices such as DV camera(IEEE1394 or i.Link) or Web camera. If no video capture device is not installed on the machine which the sender application runs on, the application will not run.
| Microsoft C runtime library: msvcr70.dll, mscvp70.dll You can get them
from the following web (they are also included in the distribution package of
FocusShare). |
| Borland C++Builder runtime library: borlndmm.dll, cc3250mt.dll You can
get them from the following web (they are also included in the distribution
package of FocusShare). |
| Codecs such as Microsoft MPEG4 codec V2 If you would like to compress
video data, you need DirectShow-compatible codec filters. If you cannot get wmpcdcs8.exe from the above link, please refer to the
followings. To install ME-MPEG4 v3 codec, please get Windows Media 9 Series Codec
Installation Package for IT Professionals (Windows Media 9 Series Codecs
installation package) WM9Codecs.exe, and install it. |
Before you can use FocusShare applications, you need to set up DirectShow filters for FocusShare.
| Sending application Double-click rsSenderUI.exe If no video capture device is found, it will terminate. |
| Receiving application Double-click rsReceiverUI.exe |
| Communication Select "Multicast" from main menu, then "Settings".
"Max. Hop Count" is appropriately specified for multicasting.
| ||||||||||||||
| Encoder You can choose a encoder from "Encoder" Menu. Unfortunately,
you cannot use all encoders listed in "Encoder" menu.
Receiving applications does not have a menu for decoder settings because the encoder information is sent as control information and the receiving application try to choose an appropriate one from installed decoders. Needless to say, the appropriate decoders have to be installed in the receiving applications.
|
| Communication Select "Multicast" from main menu, then "Settings".
To enable receiving application to communicate with sending application, please set up "Status/Control Info. Receiver" as matching sending application.
|
| Pointer-sharing If you want to run multiple receiving applications and to share multiple pointers among them, select "Poitner" from main menu, then "Settings"
To avoid address conflict, please make sure that a pair of "Multicast IP Address" and "Port Number" in "Pointer Sender" is different from the "Pointer Sender" settings of other receiving applications.
Even if you use the same "Multicast IP Address" and "Port Number" as other receiving applications, no errors are detected, however, behaviors of pointers will be strange. When pointer information is received, pointer position is updated. Thus a pointer may blink if the same settings of "Pointer Sender" are used in more than one receiving applications. Moreover, to receive pointer information properly, settings in "Pointer Receiver 1", "Pointer Receiver 2" or "Pointer Receiver 3" have to match the settings in "Pointer Sender" . Please note that an receiving application does not show its own pointer unless its pointer information is received through multicasting. |
When using IPv6, the following conditions must be satisfied. If FocusShare works using IPv4 but does not work using IPv6, please check the followings.
| Windows XP SP1 or later | ||||
| IPv6 protocol is installed For installation of IPv6 protocol, please search "IPv6" using Help system in Windows XP. | ||||
| Firewalls do not block IPv6 multicast packets (UDP) Since IPv6 Internet Connection Firewall is automatically activated as a default, you usually need to change settings of IPv6 Internet Connection Firewall.
If you use other firewalls, you need to change their settings. |
