Conditional Range Filters for Media over QUIC Transport rev 01 lands on the IETF Datatracker
In Media over QUIC Transport (MOQT), subscribers can use Range Filters to select specific subgroups, objects, or priorities within a subscribed track. However, these subscription filters are static once established and can only be modified through explicit subscriber control signaling. This document proposes an extension to the Range Filter design that binds conditional evaluation logic directly to specific Range Filter sets. By introducing dynamic conditions to Range Filter configurations, a relay can autonomously adapt the intra-track forwarding behavior based on real-time network conditions, avoiding the round-trip delay of explicit subscriber update signaling.
