It would look like the above. Additional application-specific signalling 
would also say something like this:

{
      "firstStream":
      {
          "SSRC": "11111",
          "accept": "false"
      },
      "secondStream":
      {
          "SSRC": "22222",
          "accept": "true"
      },
      "thirdStream":
      {
          "SSRC": "333333",
          "accept": "true"
      },
}
