This document describes the steps for connecting LEXI Voice to your iCap Alta TS virtual encoder.

Before You Begin

Before you perform the steps in this document:

• Make sure you have an active encoder user. If you do not, contact Ai-Media's sales team.
• Create two access codes and associate both with your encoder user:
  • A code for S1, which corresponds to your translation's input (the "from") language, and
  • A code for S2, which corresponds to the output (the "to") language.
• For information on creating access codes, visit How Do I Create an Access Code?

Configuring LEXI Live and LEXI Translate Instances

Configuring S1 for LEXI Live

To configure your S1 interface for LEXI Live:

1. Log into EEG Cloud Services with your username and password.
2. On the Home Dashboard, click LEXI Live.
3. On the LEXI Instances page, click Add New.
4. On the Edit LEXI Translate Instance page, enter a Name for your new instance, then enter your S1 Access Code.
5. Select Advanced Options and choose S1 from the CC Service menu.
   
6. Configure any other settings necessary for your site, and then click Submit. iCap Admin returns to the LEXI Instances page, where you can find or search for your new instance.

Configuring S2 for LEXI Translate

1. Click Home Dashboard in the EEG Cloud Services top toolbar, and then click LEXI Translate.
2. On the LEXI Instances page, click Add New.
3. On the Edit LEXI Translate Instance page, enter a Name for your new instance, then enter your S2 Access Code.
4. From the LEXI Voice menu, select Google.
5. In the LEXI Voice Settings, choose a Voice that fits your preference.
   
   
6. Choose different Translate From and Translate To languages or choose the same language for both to indicate no translation.
7. From the Source CC Service menu, choose CC1.
8. From the Destination Service menu, choose S2.
   
9. Configure any other settings necessary for your site, and then click Submit. iCap Admin returns to the LEXI Instances page, where you can find or search for your new instance.

Configuring Alta TS with LEXI Voice

To connect Alta TS to LEXI Voice, follow these steps. You can use an existing Alta TS channel or create a new one. The settings in these instructions assume standard ATSC User Data mode.

1. Log into Alta TS with your sever username and password.
2. To use an existing Alta channel:
   1. If the channel's State is ON, press the power button and wait until the State changes to OFF.
   2. Click Edit. The channel's settings window opens.
   3. Continue with step 4.
      
3. To create a new channel, click Add New Channel. The New Instance Settings window opens.
4. In the left toolbar, click iCap Settings, and confirm there is a packet identifier (PID) in the Audio PID field. If this field is blank, enter the PID for the source audio, which you can find in your upstream configuration.
   Note: If you leave the Audio PID field blank, LEXI Voice will not work properly with your Alta channel. 
   
5. Click LEXI Voice Settings, and then in the LEXI Voice Settings window:
   1. Click Enable LEXI Voice.
   2. Set the Output Track Type to Mono.
   3. Enter a PID and language in the Output LEXI Voice PID field, with the format [PID/language], For example,5555/eng. The system creates and carries Lexi Voice on this PID. 
      Note: Use a PID that is not in your original output configuration, otherwise the PID you set here will replace your original data.
      
6. Click Other Settings and then, in the Other Settings window:
   1. Find the output CBR (constant bit rate) in your transport stream software, and enter a CBR Transport Rate to a rate 1 Mbps higher. For example, if your software's output CBR is 25500000, enter 26500000.
   2. Set the Output Buffer Size to 1500. If you experience output underflow gaps, gradually increase the buffer size until the gaps end, up to a maximum size of 2000."
      
7. Click Create Instance, if you are creating new instance, or click Save Settings if you are editing an existing instance.
