The Enterprise Scalable Video Coding (SVC) solution is an alternative to the AVC mode that has traditionally

been supported. Differences between the two modes are listed in the following table.

The SVC solution provides the following features:

● For video send, support 270p (480x270) and 135p (240x135)

● For video receive, support up to 360p with no bandwidth limitation; average is 270p or 180p

(480x270)

● For video send, support 7.5/15 fps

● For video receive, support 7.5/15/30 fps

● Support auto layouts of 1x1, 1+1 through 1+5.

The maximum layout of 1+5 comprises 4 remote participants plus 1 content-sharing frame, and 1

local preview frame.

SVC Mode AVC Mode

Each participant in the conference call is received by the

client as a separate video stream.

The composite video image is determined by the bridge

based on administrator configuration.

A Caller ID is indicated by text in the appropriate window,

on display throughout the call.

Caller ID information is displayed intermittently.

Double-clicking or tapping on a participant’s video, content

video, or local preview expands that video to full screen.

Double-clicking or tapping again reverts the display to the

composite image.

Pinch controls enable you to zoom in and out on a

participant’s video or content video.

Layout may typically be controlled by dialing **, and

then selecting a format.
