[AVT] RTP MPEG4/H.263 packetization doubt

[Krishnan Raghavan <krishraghav at yahoo.com>]

I have a question regarding Concatenation and
Fragmentation in RTP Payload format for MPEG4/H.263.

Are the following configurations allowed ? If so, what
are the marker bits supposed to be ?

PSC = Picture Start Code (VoP Start Code)

Consider two mpeg4 frames - frame1, frame 2

(i)

RTP Packet 1:
<PSC>frame1_complete_data<PSC>frame2_data_part1
---------- Marker = TRUE/FALSE ?
RTP Packet 2: frame2_data_part2
----------------------------------------------------------------
Marker = TRUE

(ii)

RTP Packet 1:
<PSC>frame1_data_part1---------------------------------------
Marker = FALSE
RTP Packet 2: frame1_data_part2<PSC>frame2_data_part1
----------- Marker = TRUE/FALSE ?
RTP Packet 3: frame2_data_part2
-------------------------------------------------
Marker = TRUE

(iii)

RTP Packet 1:
<PSC>frame1_data_part1-------------------------------------------
Marker = FALSE
RTP Packet 1:
frame1_data_part2<PSC>frame2_complete_data------------
Marker = TRUE

cheers
Kris
