LOLA: Low Latency Audio Visual Streaming System
tools to affect the system configuration in Windows 7, they must be “run as Administrator”). It is
useful to also install test camera files which can generate synthetic video with a wide range of frame
rate and resolution characteristics. You should install the camera files for the video camera(s) you
intend to use with LOLA. The current camera files for the LOLA tested cameras are included into
the CameraFiles folder inside the LOLA distribution kit (if not already included into the BitFlow
standard distribution):
– Sony HR50: SONY-XC-HR50-EXTRIG-SHUT-MODE2.anlg
– Hitachi KP-FD30: Hitachi-RGB-648x480-ExtTrig-NTG.anlg
Hitachi-RGB-648x480-ExtTrig-NTG_bw.anlg
– Toshiba IK-TF5: Toshiba-RGB-640x480 ExtTrig.anlg
Toshiba-RGB-640x480 ExtTrig_bw.anlg
Color cameras can also run in b/w (for example because you want to reduce network
bandwidth use); you just need to load and then select the appropriate b/w configuration Camera
File, which is identified by the “_bw” postfix in the name.

available ones
When the camera files are installed, you can select the appropriate camera from the Audio
Video Setup dialog window, available in the LOLA Tools menu (Fig. 3).
LOLA allows the user to select different frame rates (from 30 up to 60 fps) from its own
setup dialog windows. In order to make this option work, the camera must be configured to
allow triggering by an external source. See Appendix D to correctly set the supported cameras.
We can also supply on request camera files with internal triggering (...SYNC-ON-VID ones) but
they should not be used with LOLA.
Camera Setup Check
After the camera files have been registered, it is recommended to check that the video
grabbing devices are working properly, by using the CiView.exe utility provided with the BitFlow
SDK in the same location as the SysReg.exe tool. Note that with this particular configuration, the
camera must triggered by an external trigger. This can be achieved by running the application in
“Free Run Mode” (this option is available in the Preview menu).
