[the rid spec](https://tools.ietf.org/html/draft-ietf-mmusic-rid-15#section-11.2) mentions dependencies between rids (using the "depend" restriction). Here is an excerpt: Adding scalable layers to a session within a multiparty conference gives a selective forwarding unit (SFU) further flexibility to selectively forward packets from a source that best match the bandwidth and capabilities of diverse receivers. Scalable encodings have dependencies between layers, unlike independent simulcast streams. RIDs can be used to express these dependencies using the "depend" restriction. In the example below, the highest resolution is offered to be sent as 2 scalable temporal layers (using MRST). See [I-D.ietf-mmusic-sdp-simulcast] for additional detail about simulcast usage. Paused - the simulcast spec talks about offer/answer negotiations specifying streams that are initially paused (using the ~ notation). the layer is still being "sent" and negotiated, but it starts out as paused. i assume that layers can pause as well. -- GitHub Notification of comment by amithilbuch Please view or discuss this issue at https://github.com/w3c/webrtc-pc/issues/2035#issuecomment-443040680 using your GitHub account
