+
+### Media types configuration
+
+The new `mediaTypes` parameter allows you to block bids whose mediaType does not match any of the media types declared at the ad unit level.
+
+### Disabling In-Banner video
+
+To block bids containing In-Banner Video creatives [IAB Creative Attributes 6 and 7, as defined in the AdCOM 1.0 specification](https://github.com/InteractiveAdvertisingBureau/AdCOM/blob/main/AdCOM%20v1.0%20FINAL.md#list_creativeattributes), configure the Bid Response Filter module to reject these responses.
+
+Restrict the ad unit to banner only and declare disallowed creative attributes (battr) directly in the ad unit definition:
+
+```javascript
+const adUnit = {
+  code: 'banner-adunit',
+  mediaTypes: {
+    banner: {
+      battr: [6, 7] // Block In-Banner Video creative attributes
+    }
+  },
+  bids: [ /* bidder configs */ ]
+};
+```
+
+Enable both the attr and mediaTypes filters in the bidResponseFilter configuration:
+
+```javascript
+pbjs.setConfig({
+  bidResponseFilter: {
+    attr: { enforce: true },
+    mediaTypes: {
+      banner: { enforce: true }
+    }
+  }
+});
+```
