An H.239 connection is initiated and terminated through the remote control using
the single Presentation source button:
Pressing this button for a short period selects the computer presentation
source and starts the H.239 link.
Pressing the button again for a short period terminates the H.239 link.
The camera occupies one channel and the source connected to either PC input the
second channel. At the remote site these two images may either be viewed on two
separate monitors or, using POP, displayed on a single large screen, depending on
the capability of the remote CODEC.
The system boots up from cold in approximately 50 seconds. When not in a call the
system automatically goes into sleep mode after a user defined period of time. It
may also be put into sleep mode via the remote control. A flashing blue light on the
monitor indicates that sleep mode is selected. An incoming call or pressing any
button on the remote control will return the system to active mode.
The comprehensive call information menu displays call status data including
connection bandwidth, frame rate, compression protocols and packet loss. During
the evaluation, in calls with some other vendors’ systems, although moving images
were in fact being transmitted the menu indicated zero (0) transmitted frame rate.

During an H.239 call three separate images, i.e. PC, near and far were displayed at
the transmit site, but the receive site could only display two simultaneous images,
those of the presentation and far images.
In calls between SCOPIA® VC240
systems it was possible to transmit two
simultaneous high resolution images at 720p; however the frame rate of the
presentation image was restricted to 2-3 frames per second at all connection speeds.
