9.1 Configuring Captions

During a conference, you can create a caption, and then overlay the caption on the video sent by the local site. The caption can be overlaid on the top, in the middle, or at the bottom of the video.

The terminal supports T.140 and non-T.140 captions. Table 9-1 describes the differences

between these two types of captions.

Table 9-1 Differences between T.140 and non-T.140 captions

Non-T.140 Caption

A non-T.140 caption will be superimposed on the local video.

T.140 Caption

A T.140 caption will be sent to remote sites and displayed on the remote displays without being superimposed on the local video.

SIP and H.323 terminals can send and receive captions.

No restriction is imposed on the terminals that send or receive non-T.140 captions.

Non-T.140 captions can be sent only from terminals in a conference, and cannot be sent from the

ResourceManager that is the videoconferencing management software.

Only H.323 terminals can send and receive captions.

If a T.140 caption is shared, both the sending and receiving parties in a conference must support

T.140 captions. Otherwise, a terminal that does not support T.140 captions cannot receive the shared

T.140 caption.

If both the sending and receiving parties in a conference support T.140 captions, a T.140 caption can be sent using any of the following methods:



Sending the caption from the chair site



Sending the caption from the ResourceManager

NOTE

Captions can be sent from either party in a point-to-point call.

The terminals' software is different from each other. Therefore, you may need to set only certain parameters instead of all of them when you prepare a caption.

Step 1 Choose Settings > Caption, and then set the parameters listed in Table 9-2.
