   + **Name**: Enter a name for your channel.
   + **Tier**: The tier determines what features the channel supports and how much it costs to run the channel. For more information about pricing, see the [Channel Assembly pricing page](https://aws.amazon.com/mediatailor/pricing/#Channel_Assembly_Pricing). MediaTailor supports the following tiers:

     + **Standard** - The Standard tier supports live sources, and requires the Linear playback mode.
