RTP Payload Format for Haptics

This memo specifies an RTP payload format for the MPEG-I haptic data. A haptic media stream is composed of MIHS units including a MIHS (MPEG-I Haptic Stream) unit header and zero or more MIHS packets. The RTP payload header format allows for packetization of a MIHS unit in an RTP packet payload as well as fragmentation of a MIHS unit into multiple RTP packets. The original subtype registration for haptics/ hmpg, registered with IANA in RFC9695, did not include any required or optional parameters. This memo updates RFC9695 and the haptics/ hmpg registration to add optional parameters. It also provides SDP usage information for the haptics media type.
