Chapter 2Using ViaVideo

Snapshot	Sends a high-resolution still image, or snapshot,
	to the far site during a call.
	This feature is designed for far sites that use the
	Annex D high-resolution (704 x 576) graphics
	standard. These are typically conference room
	video communications systems, such as
	Polycom ViewStations.
	Systems using lower resolution graphics
	transfer standards (for example, QCIF,
	NetMeeting) are not able to receive high
	resolution snapshots.
Volume	Controls audio volume received from the far site.
	For more information about controlling audio,
	see “Controlling Audio,” on page 27.
Audio Mute	Mutes outgoing audio to the far site. When this
	option is selected, the audio mute icon is
	displayed on the screen (the far site does not
	see the icon). ViaVideo maintains the audio
	mute setting between calls.
