2.2.1.1 General Usage

  • Article

The RTP payload format defined in this section is suitable for any kind of multimedia data that is encapsulated in ASF data packets. The RTP payload format is used for audio streams and video streams, as well as streams of any of the other types, as specified in [ASF].

ASF data packets can contain multiple payloads from different streams of different types. Therefore, it is possible for a single RTP packet to contain both audio and video data because the ASF packet contained in the RTP packet can multiplex data from different streams.

This RTP payload format allows for multiple ASF data packets to be combined into a single RTP packet. It is also possible to split (fragment) an ASF data packet across several consecutive RTP packets.

Each ASF data packet, or fragment thereof, is preceded by an RTP payload format header, specified in section 2.2.1.3.
