  1. 3D Video in the Session Description Protocol (SDP)draft-capelastegui-mmusic-3dv-sdp-00 Pedro Capelastegui capelastegui@dit.upm.es

  2. 3D Video in SDP • Goal: Describe 3D video streams in SDP • 3DV stream: • Composed of 2+ streams: views, depthmaps • 3DV formatoptions: simulcast, video-plus-depth, frame-packing • Extensionrequirements: • 3DV formatnegotiation • Relationshipbetweenviews/maps of 3DV stream

  3. Additionsto SDP • New media-levelattribute: “3dvFormat” • 3D formatfor a media description • Associatedto media format (payloadtypenumber) • Fourdefinedformats a=3dvFormat:<fmt> <attribute>:<value> • New decodingdependency [RFC 5583]: “3dd” • Dependencybetweenviews/maps in 3DV stream • A “DDP” grouprepresents a single 3DV stream

  4. SDP Example 2 media descriptions, 5 3D configurations • 2D video • fmt: 99,0 • Frame-packing • fmt: 100, 0 • Video-plus-depth • fmt: 99, 99 • Simulcast, view + depthmap: • fmt: 99, 100 • Simulcast, 2 views • fmt: 99, 101 a=group:DDP1 2 m=video 1111 RTP/AVP 99100 a=rtpmap:99 H264/90000 a=3dvFormat:99stereo-view:left a=rtpmap:100 H264/90000 a=3dvFormat:100frame-pack:side-by-side a=mid:1 m=video 1112 RTP/AVP 99100101 a=rtpmap:99 H264/90000 a=3dvFormat:99depth-map-metadata:1 a=rtpmap:100 H264/90000 a=3dvFormat:100depth-map-simulcast:1 a=rtpmap:101 H264/90000 a=3dvFormat:101stereo-view:right a=mid:2 a=depend:99 3dd 1:99; 100 3dd 1:99; 101 3dd 1:99
