 ## Attributes ## {#RTCRtpScriptTransformer-attributes}
 
 A {{RTCRtpScriptTransformer}} has the following private slots called `[[depacketizer]]`, `[[encoder]]`, `[[options]]`, `[[readable]]` and `[[writable]]`.

-## Attributes of BandwidthInfo ## {#BandwidthEstimate-attributes}
-The <dfn attribute for="BandwidthEstimate">allocatedBitrate</dfn> attribute represents the bandwith that the downstream
-entity recommends to be allocated for media from this source. If this number is exceeded, the downstream entity
-can drop frames to stay within the allocated bandwidth limit.
-
-The <dfn attribute for="BandwidthEstimate">availableOutgoingBitrate</dfn> attribute represents the overall bandwidth estimate
-of the downstream entity - for an {{RTCRtpSender}}, this is the same number as the {{RTCIceCandidatePairStats/availableOutgoingBitrate}} of the {{RTCIceCandidatePair}} object that is currently supporting the transport.
-
-The <dfn attribute for="BandwidthEstimate">writable</dfn> attribute is true whenever it is possible to enqueue a
-frame for processing without it being immediately discarded. Note that delivery is not guaranteed under any circumstance.

 ## Events ## {#RTCRtpScriptTransformer-events}
 
 The following events fire on an {{RTCRtpScriptTransformer}}:
 
-* bandwidthestimate of type {{Event}} - fired when the sink determines that the bandwidth estimate has changed significantly from what has been previously signalled. Significant changes include a change to the "writable" attribute, a decrease of the "allocatedBitrate" attribute, or an increase of more than 10% of the "allocatedBitrate" attribute. In the context of {{RTCRtpScriptTransform}}, if the event is not cancelled, the information will be passed to the source as if the sendBandwidthEstimate() function had been called.
-
 * keyframerequest of type {{KeyFrameRequestEvent}} - fired when the sink determines that a key frame has been requested. In the context of {{RTCRtpScriptTransform}}, if the event is not cancelled, the information will be passed to the source as if the generateKeyFrame() function had been called. <!-- NOTE IN DRAFT: generateKeyFrame() and requestKeyFrame() should merge -->

 ## KeyFrame Algorithms ## {#KeyFrame-algorithms}
 
 The <dfn abstract-op>generate key frame algorithm</dfn>, given |promise|, |encoder| and |rid|, is defined by running these steps:
