Media Over QUIC (moq) ----------------------------------------------------------------------- Current status: BOF WG Chairs: Ted Hardie <ted.i...@gmail.com> Alan Frindell <afr...@fb.com> Assigned Area Director: Murray Kucherawy <superu...@gmail.com> Applications and Real-Time Area Directors: Murray Kucherawy <superu...@gmail.com> Francesca Palombini <francesca.palomb...@ericsson.com> Mailing list: Address: m...@ietf.org To subscribe: https://www.ietf.org/mailman/listinfo/moq Archive: https://mailarchive.ietf.org/arch/browse/moq/ Group page: https://datatracker.ietf.org/group/moq/ Charter: https://datatracker.ietf.org/doc/charter-ietf-moq/ Media over QUIC (moq) will develop a simple low-latency media delivery solution for ingest and distribution of media. This solution may address use cases including live streaming, gaming, and media conferencing and will scale efficiently. The solution will be implementable in both browser and non-browser endpoints. The work focuses on building protocol mechanisms for publication of media and means to identify and receive the media. The media publication protocol will enable sending media including audio, video, and timed metadata, such as closed captions and cue points. The common protocol for publishing media for ingest and distribution will support: * one or more media formats, * an interoperable way to request media and encodings, * rate adaptation strategies based on changing codec rates, changing chosen media encoding/qualities, or other mechanisms * cache friendly media mechanisms The mechanism to name and receive media will enable: * Requesting the server start sending media related to a given point in the stream * Selection of desired encoding (choosing language, bit rate, etc.) Media will be mapped onto underlying QUIC mechanisms (QUIC streams and/or QUIC datagrams) and can be used over raw QUIC or WebTransport. The proposed solution will provide extensibility for supporting different media formats and shall specify a mandatory to implement media format to ensure interoperability. The proposed solution will support multiple media types and media encodings. The working group will define MoQ so that the media publication protocol can leverage coordinating relays, caches, or replication points wherever applicable to improve the delivery performance. The solution will specify a simple method for clients to authenticate to the relay or server to transmit or receive media. Media will be encrypted at the transport layer using the standard QUIC mechanisms. Media content may be end-to-end encrypted in certain use cases, where the "end-to-end" keys are available to media sources and consumers, but not relays. Even when media is end-to-end encrypted, the relays can access metadata needed for caching (such as timestamp), making media forwarding decisions (such as drop or delay under congestion), and so on. Such media metadata will be authenticated and integrity-protected end-to-end. Mechanisms for establishing keys for these end-to-end protections are outside the scope of this group. This working group will not propose changes to the underlying QUIC transport, but may propose requirements for QUIC extensions to the QUIC WG. This working group will not define signaling mechanisms for discovery of relay or media producers or consumers. This working group will coordinate with the QUIC, WebTransport, and MOPS working groups as needed. It will liaise with MPEG Systems WG, DASH Industry Forum, and W3C WebTransport as appropriate.
