RTP Payload Format for Uncompressed Video

How to Write an RTP Payload Format

“…If earlier wrapping may occur, then the payload format should specify an extended sequence number field to allow the receiver to determine where a specific payload belongs in the sequence, even in the face of extensive reordering. The RTP payload format for uncompressed video [RFC4175] can be used as an example for such a field.…”

“…The RTP payload format for uncompressed video [RFC4175] must be mentioned in this context as it contains a special feature not commonly seen in RTP payload formats. Due to the high bitrate and thus packet rate of uncompressed video (gigabits rather than megabits per second) the payload format includes a field to extend the RTP sequence number since the normal 16-bit one can wrap in less than a second.…”

“…For example, video formats that need a media parameter expressing color sub-sampling may be able to reuse those defined for 'video/raw' [RFC4175].…”

Uncompressed High Definition Visual Sharing System towards Interactive Networked Collaboration

“…UltraGrid has potentials to support two types of RTP payload formats: Circuit emulation [12] and native packetization [13]. Circuit emulation packetizes and transports SMPTE292M signal to get compatible with other industrial products using HD-SDI interfaces.…”

“…5) to make synchronization easily and to cope with channel loss robustly. Note that payload header for uncompressed video format is defined in [13]. When we grab an audio frame with pseudo circuit emulation, the number of samples per audio frame will be variable (e.g., the number of samples equals to the truncation of 48KHz/29.97fps and a surplus.).…”
