The data is generated according to document Q15-I-61.
Error patterns are available in Q15-I-16r1.

The following sequences and rates are specificied.

Hall    QCIF  10  fps  32  kbps 
Foreman QCIF  7.5 fps  64  kbps
Foreman QCIF  7.5 fps  144 kbps
Paris   CIF   15  fps  144 kbps
Paris   CIF   15  fps  384 kbps
Irene   CIF   30  fps  384 kbps

For each sequence, 4000 coded frames are provided, looping 
the sequence as necessary, with an I-frame used each time 
the loop restarts.

The high complexity H.323 mode of TMN11 is employerd, with
rate-distoriton optimized PLR-aware encoding, TCON error 
concealment method, and Annexes D, F, I, J, and T employed. 

GOB headers are inserted at the beginning of every 
macroblock row. 

For rate control, a packetization overhead of 40 bytes per 
packet is deducted from the above target bit rates.

It is important to note that PSNR calculations are a little 
different than usual. PSNR is calculated for full frame 
rate, i.e. 30 fps. Where one or more coded frames is lost 
or when complete frames are skipped due to the reduced 
target frame rate, the last decoded frame is repeated for 
the purpose of calculating PSNR.

The bitstream file name format are:
 <sequence>_<bit_rate>_<plr>.263

The data files are:

- d0.txt: Encoder assume correct PLR 0%, i.e. error-free.
- d1.txt: Encoder assumes correct PLR for each of 3, 5, 10, 
and 20%.
- d2.txt: Encoder assumes incorrect PLR of 0% always for each
of 3, 5, 10, and 20%.
