Chapter 4 - Hardware Description

The maximum transmission capability of E1 lines (up to 1920 Kbps) can be used in Transcoding or Continuous Presence conferences. To enable the high line rate transmission, a newer video card version (version 1.43 and up) must be installed.

Figure 4-12 describes the various video card versions and their support of 30 frames per second and high bit rate:

Table 4-5: Video card 30 FPS and high bit rate support

Video Card Version

30 FPS Support

High Bit Rate Support

 

 

 

1.20, 1.21, 1.22, 1.23

 

 

 

1.24

 

 

 

1.41, 1.42

 

 

 

1.43, 1.44 or higher

 

 

 

If the High Bit Rate flag is set to Yes, and the MCU contains video cards of a version older than 1.43, the MCU status changes to Major and an appropriate error message is added to the Faults log. In such a case, the highest line rate that can be set for the conference is 768 Kbps. If the High Bit Rate flag is set to No, the high bit rate option is disabled and the highest conference rate is limited to 768 Kbps.

Video+ Module

The Video+ module supports up to 8 participants per module. In addition it provides the following features/enhancements:

Click&View - A graphical console transmitted to endpoints enabling the users to change their personalized video layout or conference.

Personal Layout - Definition and on-the-fly modification of individualized participant Continuous Presence layouts. For details, see Personal Layout

Visual Effects - Definition of background colors, frame colors and frame widths for Continuous Presence layouts. For details, see Visual Effects
