 For details on how to create or update asset filters, see [Create or update](https://docs.microsoft.com/rest/api/media/assetfilters/createorupdate). Also, see [JSON examples for filters](https://docs.microsoft.com/rest/api/media/assetfilters/createorupdate#create_an_asset_filter). 
 
+## Associate filters with Streaming Locator
+
+You can specify a list of asset or account filters, which would apply to your Streaming Locator. The [Dynamic Packager (Streaming Endpoint)](dynamic-packaging-overview.md) applies this list of filters together with those your client specifies in the URL. This combination generates a [Dynamic Manifest](filters-dynamic-manifest-overview.md), which is based on filters in the URL + filters you specify on Streaming Locator. We recommend that you use this feature if you want to apply filters but do not want to expose the filter names in the URL.
+
+To create and associate filters with a Streaming Locator using REST, use the [Streaming Locators - Create](https://docs.microsoft.com/rest/api/media/streaminglocators/create) API and specify `properties.filters` in the [Request Body](https://docs.microsoft.com/rest/api/media/streaminglocators/create#request-body).

+## Stream using filters
+
+Once you define filters, your clients could use them in the streaming URL. Filters could be applied to adaptive bitrate streaming protocols: Apple HTTP Live Streaming (HLS), MPEG-DASH, and Smooth Streaming.
+
+The following table shows some examples of URLs with filters:
+
+|Protocol|Example|
+|---|---|
+|HLS|`https://amsv3account-usw22.streaming.media.azure.net/fecebb23-46f6-490d-8b70-203e86b0df58/bigbuckbunny.ism/manifest(format=m3u8-aapl,filter=myAccountFilter)`|
+|MPEG DASH|`https://amsv3account-usw22.streaming.media.azure.net/fecebb23-46f6-490d-8b70-203e86b0df58/bigbuckbunny.ism/manifest(format=mpd-time-csf,filter=myAssetFilter)`|
+|Smooth Streaming|`https://amsv3account-usw22.streaming.media.azure.net/fecebb23-46f6-490d-8b70-203e86b0df58/bigbuckbunny.ism/manifest(filter=myAssetFilter)`|
