Complete narration
0:00 · Many voices, a wider audience
An assembly brings together delegations from many places. Hundreds of people can take part in the discussion. Millions may want to follow it. How can this meeting organize participation and distribute its voices without concentrating all media in one application server?
0:19 · Participation has its own reference
In PRP, groupcast gives the group its own reference and participation governed by authorized identities. The assembly application decides who may take the floor. Group membership does not automatically grant every right to speak or transmit.
0:37 · Independent sources
Amara presents her proposal. Kenji responds. Each stream has its own reference and authorized source. The application associates these streams with the meeting. The group organizes participants without turning all their voices into a single source.
0:56 · Shared distribution paths
Aggregators distribute each stream along paths to its recipients. Shared stretches can feed further branches. The source does not need to send a separate copy to every viewer. Distribution grows through cooperation across the network.
1:13 · Watching and deliberating
The assembly chooses which streams to make public. Millions can follow without joining the deliberating group. Carrying these voices does not grant the right to admit delegates, claim authorship, or control who may speak.
1:28 · The group continues
One stream ends. Another begins. Sessions can change while the group continues. This organization depends on valid state, available paths, and capacity.
1:41 · Return to the audience
Many voices take part. A larger audience follows. The group organizes participation. The network distributes the streams. Groupcast. PRP.
Visual description by scene
0:00 · Many voices, a wider audience
Amara, a Black woman with short natural hair and a teal blazer, sits behind a laptop and microphone. A four-panel view adds Kenji, a grey-haired man in a grey shirt, Sofia, a brown-haired woman in a plum blazer, and an audience watching them on a screen. The delegates blink, and Amara and Kenji make small hand gestures. Text reads: Hundreds of delegates; potential audience: millions; illustrative scenario.
0:19 · Participation has its own reference
On a cream background, a pale green group area contains portraits of Amara, Kenji and Sofia. A card labels the assembly group. Amara and Sofia are labeled Admin; Kenji is labeled Participant. A sentence states that speaking permissions are defined by the application.
0:37 · Independent sources
Amara connects to a teal Stream A card and Kenji to an amber Stream K card. Arrows and moving dots also carry A to Kenji and K to Amara. Purple dashed lines associate both stream cards with the assembly group, distinguishing application association from data transport.
0:56 · Shared distribution paths
The delegates appear at left, round aggregators R1, R2 and R3 in the center, and recipient symbols at right. Teal paths branch from Amara through R1 toward recipients; amber paths add Kenji's independent stream. Branches also deliver each delegate's stream to the other. Moving dots and arrowheads indicate direction; colors retain source identity on shared infrastructure.
1:13 · Watching and deliberating
Amara appears above Kenji inside the deliberating-group area. The teal stream leaves Amara, reaches R4 and branches to Kenji and the public audience. The amber stream leaves Kenji, reaches R5 and branches to Amara and the audience. Arrowheads and moving dots show direction. Labels identify what each delegate sends and receives. Neither stream is drawn returning to its own source.
1:28 · The group continues
A card reading Same group reference remains while Session 1 fades and Session 2 appears. Text below lists valid group state, available paths and capacity. The group reference persists through the session change.
1:41 · Return to the audience
The audience watches the three delegates on a large screen. The closing card shows the official PRP logo, The Group Continues and prp-protocol.org on a cream background.
