H.223 Reference Bitstreams

The reference H.223 bitstreams included in this packet have been validated by 
ITU-T Q11/SG16 Mobile Interoperability Testing ad-hoc group in December 1998. 

The bitstreams have been generated according to interoperability test plan, phase 1
(the latest version is q11i12.doc).
Detailed parameters of the bitstreams are like the following.

Case 1

Audio:
input 512 times ramp 0..255	(131 072 octets)
AL-type AL2 without sequence numbers
AL-SDU size 256 octets
segmentable channel

Video: 
input 512 times ramp 0..255	(131 072 octets)
AL-TYPE AL3 control field 0 octets
AL-SDU size 256 octets
segmentable channel

Multiplex table entries
1	audio, repeat until closing flag
4	video, repeat until closing flag

Multiplexed files:
rampL0.223	Level 0
rampL1.223	Level 1 (Annex A)
rampL1d.223	Level 1 with double flag
rampL2.223	Level 2 (Annex B)
rampL2o.223	Level 2 with optional header (Note! Optional header is included also in the initialization sequence)

All files were demultiplexed correctly, i.e., input and output files are bit exactly same


Case 2

Audio:
input jap63.723
AL-type AL2 without sequence numbers
AL-SDU size 24 octets
non-segmentable channel

Video:
input tstvideo.263
AL-TYPE AL3 control field 0 octets
AL-SDU size 120 octets
segmentable channel

Multiplex table entries
1	audio, repeat 25 octets
4	video, repeat until closing flag

Multiplexed files:
audvidL0.223	Level 0
audvidL1.223	Level 1 (Annex A)
audvidL1d.223	Level 1 with double flag
audvidL2.223	Level 2 (Annex B)
audvidL2o.223	Level 2 with optional header (Note! Optional header is included also in the initialization sequence)

Only level 1 demultiplexed video file (demuxed from audvidL1.223, containing 1 CRC error) differs from the input file, and it is included in the package (videol1.263)
