Definition at line 2505 of file TeamTalk.h.

## ◆ transmitUsers

INT32 Channel::transmitUsers[TT_TRANSMITUSERS_MAX][2]

List of users who can transmit in a channel.

`transmitUsers` is a 2-dimensional array which specifies who can transmit to the channel.

If `uChannelType` is set to CHANNEL_CLASSROOM then only the users in `transmitUsers` are allowed to transmit.

In TeamTalk v5.4 and onwards adding a user ID to `transmitUsers` will block the user from transmitting if the ChannelType is not CHANNEL_CLASSROOM. Basically the opposite effect of CHANNEL_CLASSROOM.

To specify user ID 46 can transmit voice to a CHANNEL_CLASSROOM channel is done by assigning the following:

    * transmitUsers[0][0] = 46;
    * transmitUsers[0][1] = STREAMTYPE_VOICE;
    *

To specify user ID 46 can transmit both voice and video capture to a CHANNEL_CLASSROOM channel is done by assigning the following:

    * transmitUsers[0][0] = 46;
    * transmitUsers[0][1] = STREAMTYPE_VOICE | STREAMTYPE_VIDEOCAPTURE;
    *

The transmission list is terminated by assigning user ID 0 to the end of the list, i.e.:

    * transmitUsers[0][0] = 0;
    * transmitUsers[0][1] = STREAMTYPE_NONE;
    *

To allow all users of a CHANNEL_CLASSROOM channel to transmit a specific StreamType is done like this:

    * transmitUsers[0][0] = TT_CLASSROOM_FREEFORALL;
    * transmitUsers[0][1] = STREAMTYPE_VOICE;
    *

Only channel operators are allowed to change the users who are allowed to transmit data to a channel. Call TT_DoUpdateChannel() to update the list of users who are allowed to transmit data to the channel.

## ◆ transmitUsersQueue

INT32 Channel::transmitUsersQueue[TT_TRANSMITQUEUE_MAX]

The users currently queued for voice or media file transmission.

This property only applied when channel is configured with CHANNEL_SOLO_TRANSMIT. Read-only property.

Definition at line 2566 of file TeamTalk.h.

## ◆ nTransmitUsersQueueDelayMSec

INT32 Channel::nTransmitUsersQueueDelayMSec

Delay for switching to next active voice user in `transmitUsersQueue`.

In channels of type CHANNEL_SOLO_TRANSMIT only one user can transmit voice. When user has stopped transmitting this value specifies the delay before switching to next user in `transmitUsersQueue`. Default value is 500 msec.

Definition at line 2574 of file TeamTalk.h.

## ◆ nTimeOutTimerVoiceMSec

INT32 Channel::nTimeOutTimerVoiceMSec

Time out timer for voice stream. The maximum time in miliseconds a user can transmit voice without changing stream ID.

See also
  STREAMTYPE_VOICE

Definition at line 2578 of file TeamTalk.h.

## ◆ nTimeOutTimerMediaFileMSec

INT32 Channel::nTimeOutTimerMediaFileMSec

Time out timer for media file stream. The maximum time in miliseconds a user can transmit a media file.

  STREAMTYPE_MEDIAFILE_AUDIO
