Applications Independent Submission IRC Internet Relay Chat Audio Video This document describes version 3 of the Internet Relay Chat (IRC) protocol, which extends the original IRC protocol to include support for audio and video capabilities. It defines new message types, commands, and channel modes that allow for the transmission of audio and video data within the existing IRC framework, while maintaining backward compatibility with text-only clients and servers.

The Internet Relay Chat (IRC) protocol, originally defined in RFC 1459 and updated in RFCs 2810-2813, provides a lightweight, text-based communication system. This document introduces version 3 of the IRC protocol, which extends the original protocol to include support for audio and video capabilities, allowing users to exchange multimedia content within the familiar IRC framework. IRC v3 aims to maintain the simplicity and flexibility of IRC while adding the ability to transmit audio and video data. It achieves this by introducing new message types, channel modes, and permissions, and by leveraging the existing Direct Client-to-Client (DCC) mechanism for larger data streams.

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in .

IRC v3 introduces the following key components: Extensions to DCC for audio and video streaming New channel modes for audio and video capabilities Extended user modes and flags for audio and video permissions Modified JOIN command to specify media preferences New PRIVMSG subcommands to manage media streams Server-to-server commands for propagating A/V metadata

The introduction of audio and video capabilities brings new security considerations to IRC: Denial of Service: Implementations MUST include measures to prevent abuse of audio/video streams that could lead to denial of service. Privacy: Users MUST be clearly informed when audio/video streams are being initiated or received. Content Verification: Clients SHOULD implement measures to verify and sanitize received audio/video content to prevent potential attacks through malformed data. Encryption: All audio and video streams MUST be encrypted using TLS 1.3 or later to ensure user privacy.

This document requires IANA to update the IRC protocol registration to reflect the new version number and capabilities described herein.
