 # Branch API Reference
-Branch components are similar to Pipelines in the way they're used to manage and link Child components when transitioning to states of `ready`, `paused`, and `playing`. Unlike Pipelines, Branches can not contain Source components, and must be added to a [Demuxer or Splitter Tee](/docs/api-tee.md). 
+Branch components are similar to Pipelines in the way they're used to manage and link Child components when transitioning to states of `ready`, `paused`, and `playing`. Unlike Pipelines, Branches can not contain Source components, and must be added to a [Demuxer or Splitter Tee](/docs/api-tee.md) or [Remuxer](/docs/api-remuxer.md). 
 
 #### Branch Construction and Destruction
 Branches are constructed by calling [`dsl_branch_new`](#dsl_branch_new),[`dsl_branch_new_many`](#dsl_branch_new_many),  [`dsl_branch_new_component_add_many`](#dsl_branch_new_component_add_many), and destructed by calling `[dsl_branch_delete`](#dsl_branch_delete), `[dsl_branch_delete_many`](#dsl_branch_delete_many), or [`dsl_branch_delete_all`](#dsl_branch_delete_all). Deleting a Branch will not delete its child components but will unlink then and return to a state of `not-in-use`. The client application is responsible for deleting all child components by calling [`dsl_component_delete`](/docs/api-component.md#dsl_component_delete), [`dsl_component_delete_many`](/docs/api-component.md#dsl_component_delete_many), [`dsl_component_delete_all`](/docs/api-component.md#dsl_component_delete_all), or [`dsl_delete_all`](/docs/overview.md#dsl-delete-all).

 Pipelines can have multiple Primary GIE or TIS -- linked in succession to operate on the full frame -- with any number of corresponding Secondary GIEs or TISs (only limited by hardware). Pipelines cannot be created with a mix of GIEs and TISs. Pipelines that have secondary GIEs/TISs but no Primary GIE/TIS will fail to Link and Play. Secondary GIEs/TISs can `infer-on` both Primary and Secondary GIEs/TISs creating multiple levels of inference. **IMPORTANT**: the current release supports up to two levels of secondary inference.
 
 ### Construction and Destruction
-Primary GIEs and TISs are constructed by calling [`dsl_infer_gie_primary_new`](#dsl_infer_gie_primary_new) and [`dsl_infer_tis_primary_new`](#dsl_infer_tis_primary_new) respectively. Secondary GIEs and TISs are created by calling [`dsl_infer_gie_secondary_new`](#dsl_gie_secondary_new) and [`dsl_infer_tis_secondary_new`](#dsl_infer_tis_secondary_new) respectively. As with all components, Primary and Secondary GIEs/TISs must be uniquely named from all other components created.

Once created, clients can query both Primary and Secondary GIEs/TIEs for their Config File in-use by calling [`dsl_infer_config_file_get`](#dsl_infer_config_file_get) or change the GIE/TIS's configuration by calling [`dsl_infer_config_file_set`](#dsl_infer_config_file_set).
