H.261 Payload Format

An H.261 video frame is fragmented and converted to packets using the mechanism specified in [RFC2032] and in this document.

An H.261 video frame is constructed by concatenating H.261 video payload data of all RTP packets for the video frame.

H.261 video packets are considered to be complete if they satisfy the following condition:

  • An H.261 I-Frame SHOULD be sent every 15 seconds.

Note The above conceptual data can be implemented using a variety of techniques. An implementation is at liberty to implement such data in any way it pleases.
