WebRTC Object Model API - Transceivers
The document presents concepts and use cases related to WebRTC RTP transceivers, highlighting various examples including audio-only, audio and video, and audio-video-data combinations. It discusses the roles of RTP sender, receiver, and the significance of DTLS, ICE transports, and data channels. Additionally, it notes that further examples and SDPs for multi-party scenarios, simulcast, and more will be provided.
